Setting Up a Plumbing Drawing

There are three common ways to start new drawings.

The first method is to copy and rename a drawing from

a recent job that is of the same type as the new job. The

second is to create a prototype job setup containing

drawings with externally referenced borders and office-

or job-specific styles. The third method is to use a tem-

plate with standard text and dimension styles set up in

the drawings.

Templates provide a way to implement consistent stan-

dards, reduce errors, and increase drawing accuracy.

Autodesk® Building Systems includes templates that let

you start drawing right away. This chapter looks at the

templates in Autodesk Building Systems and the settings

that create your drawing environment.

Lessons in this chapter:

■ Lesson 1: Starting Out Right

■ Lesson 2: Specifying Drafting and Design Preferences

■ Lesson 3: Creating Plumbing Tables

2 | Chapter 1 Setting Up a Plumbing Drawing

Lesson 1: Starting Out Right

This lesson introduces you to the templates installed with Autodesk Building Systems, and how they can be used in the Plumbing module. The templates have predefined plumbing systems and schematic line and system styles, plus display configurations for specific layouts to be used with the plumbing objects. While your office might use a method other than templates to start new drawings, the two exercises in this lesson follow a workflow that is per-formed for every new job. Following the steps presented in these exercises assures that your drawing will be set up to take full advantage of the func-tionality in the Plumbing module.

Exercises in this lesson:

■ Exercise 1: Starting a Drawing with a Template

■ Exercise 2: Externally Referencing an Architectural Drawing

Exercise 1: Starting a Drawing with a Template

When you begin using the Plumbing module, it is recommended that you start with the template named Aecb Plumbing Model (Metric - ctb) 4.dwt. Its sys-tem definitions, styles, and layer controls can help you get started quickly. By

using an Aecb template, most of the AEC objects from Autodesk® Architec-tural Desktop change to gray (screened). This is a customized display config-uration found only in the Aecb templates.

Another template you might find helpful is ABS Model (Metric Ctb).dwt. The Building Model template is a combination of templates from all three Autodesk Building Systems disciplines, so it includes system definitions and styles for mechanical, electrical, and plumbing.

Each of the Model templates included with Autodesk Building Systems includes three layouts. The Model layout is used primarily for working in either plan or three-dimensional (3D) view, the Work layout provides a method for you to see both two-dimensional (2D) and 3D views as you work, and the Plot layout includes a default title block for your final plotted draw-ings.

Help link Templates

After you become familiar with Autodesk Building Systems, you can create your own templates and layout tabs based on your office standards and project-specific standards. Until then, using a template or layout tab supplied

Lesson 1: Starting Out Right | 3

with Autodesk Building Systems’ standard installation can help you to work efficiently, maintain consistency, and automate repetition.

This exercise shows how to open a template and view the template’s systems, styles, and layering. The Building Model template is used to give you a real-world example of the benefits of removing any layouts that you do not need.

Open an ABS template

1 Do one of the following:

■ If Autodesk Building Systems 2005 is already running on your com-puter, on the File menu, click New.

■ If you have not already launched the product, double-click the Autodesk Building Systems 2005 icon on your desktop, and on the File menu, click New.

NOTE If you do not have an Autodesk Building Systems 2005 icon on your desktop, or if you have multiple icons for the product, see the Autodesk Build-ing Systems 2005 Installation Guide for further instructions.

2 Select ABS Model (Metric Ctb).dwt, and click Open.

Look at the template-supplied schematic pipe styles

3 Open the Plumbing tool palette and click the Add Schematic Pipe tool.


4 Select Domestic Cold Water for System.

Notice that the template includes several systems for schematic pipes.

5 Select Copper Tube - Type K for Style.

Many schematic pipe styles have been set up for you. If you do not start with a template, the only option for System and Style will be Standard.

6 Select 20.00 mm for Nominal Size.

The sizes that are displayed are part of the Copper Tube - Type K style. The range of sizes varies with the style you select.

Add a pipe to see automatic layering

7 Click in the drawing to move the focus out of the dialog box.

8 Select a starting point for the schematic pipe.

When you establish your starting point in the drawing, the Compass is displayed. The Compass is a navigation tool that helps guide you during layout. When you specify an insertion point and move the cursor in any direction, the Compass displays the angle of the cursor position relative to the specified point.

9 Specify an ending point for the pipe.

10 Right-click, and click Enter to end the command.

11 Select the pipe and verify that it is on layer P-Domw-Pipe.


The automatic layering is taken care of with a layer key. If you start a draw-ing without using a template, the drawing does not include layer keys, and the pipe is placed on the current layer.

12 Right-click, and click Deselect All to turn off the grips.

Specify the layer key style and drawing scale for the current drawing

The Drawing Setup dialog box contains the layer standard, layer key style, drawing scale, and other drawing setup values for the current drawing. You can modify the values on any of the Drawing Setup tabs, and apply them to your drawing. You can also establish default drawing setup values using the Save As Default option. Default drawing setup values are stored in the registry, and are applied to any drawing started with a template that does not contain drawing setup values.

13 On the Format menu, click Drawing Setup.

14 Click the Layering tab.

15 Verify that the Layer Standards/Key File to Auto-Import is AecbLayerStd5.dwg. If this is not the default:

■ Click the [...] button next to Layer Standards/Key File to Auto-Import.■ Browse to c:\Documents and Settings\All Users\Application

Data\Autodesk\ABS 2005\enu\Layers.■ Select AecbLayerStd5.dwg, and click Open.

16 Under Default Layer Standard, select Pipe - AIA 256 Color for Layer Key Style.

NOTE The individual layer key styles named Mechanical, Electrical, and Plumbing have only the layer keys for the individual modules within Autodesk Building Systems. For example, if you add a schematic pipe to a drawing that uses the Electrical layer key style, the pipe is placed on layer 0 because there is no layer key for schematic pipe in the Electrical layer key style.


17 Click the Scale tab.

18 Verify that the Drawing Scale is 1 = 100 mm and the Annotation Plot Size is 3.50, and click OK.

NOTE Many of the labels and annotations use the current text style and dimension style. If you are using this exercise as a guide while you work on a drawing for your office, change the text and dimension styles to your office standards. You can use the DesignCenter to drag these styles into your draw-ing from an existing drawing that contains them. Optionally, you can insert the office prototype into your drawing.

As you become more familiar with Autodesk Building Systems, you may want to create one or more templates for your office. If you create a cus-tom template to use with different layer key styles, you must purge all the layer key styles immediately before saving the template. Use the AECPURGELAYERSTYLES command to completely purge the layer key styles and standards from a drawing before saving it as a template (DWT) file.


NOTE To import a Layer Standard and Layer Key Style when new drawings are created, select a file in the Layer Standards/Key File to Auto-Import field, select Save As Default, and click OK.

19 On the File menu, click Close. Click No when you are prompted to save the drawing.

In this exercise, you opened the Building Model template and viewed the template’s predefined systems, styles, and layering capabilities that help you standardize drawings. Next, you insert an external drawing into your current drawing in order to reference the architectural floor plan for the building in this sample project.

Exercise 2: Externally Referencing an Architectural Drawing

The ability to link external drawings into your current drawing is powerful as part of your project standards. Design projects typically involve the coor-dination of many drawing files, and sharing the content contained in those drawings is fundamental to efficient project management. Establishing stan-dards for using external reference files (xrefs) provides for the optimal use of drawings, while minimizing the need to re-create drawing content.

Xrefs allow you to assemble master drawings from individual design draw-ings without significantly increasing the size of your drawing files. You can create borders and title blocks as xrefs for easy maintenance. You can refer-ence all or part of another drawing by using xrefs, which allows you to coor-dinate your group’s work by overlapping data to keep up with changes being made.

This exercise introduces you to the use of xrefs and layers. Organizing layers, and objects on layers, makes it easier to manage the information in your drawings. In Autodesk Building Systems, the Layer Manager provides a cen-tral location to help you organize, sort, and group layers.

In this exercise, you use the Layer Manager to create a layer filter group to isolate and control specific layers of the architectural drawing. You also create a snapshot of the current layer settings. When you receive a new drawing, it is useful to capture the current layer settings in a snapshot for reference later in the design process. You can restore layer settings at any time to those set-tings that existed when the snapshot was taken.


NOTE A Tutorial layout tab has been added to the dataset files for your work in the tutorial exercises. While working on this layout tab, you can change dis-play configurations “on the fly” by using the Display Configuration list at the bottom right of the drawing window.

Dataset Open c:\Program Files\Autodesk Building Systems 2005\Tutorial\Building Systems\Metric Tutorials\Plumbing\m_abp5_L01_E2.dwg.

NOTE All datasets are read-only files.

Externally reference the architectural floor plan

1 On the Insert menu, click External Reference.

2 Browse to c:\Program Files\Autodesk Building Systems 2005\Tutorial\Build-ing Systems\Metric Tutorials\Plumbing.

3 Select m_A-FP-01_P.dwg, and click Open.

4 Under Insertion point, clear Specify On-screen.

5 Verify that the X, Y, and Z coordinates are set to 0.00, and click OK.

NOTE If your external reference has red circles in some of the wall loca-tions, or if the walls do not clean up correctly, you need to regenerate the model. On the View menu, click Regen All. This command refreshes the rela-


tionships among the AEC objects in the drawing, and the walls should clean up.

Add pipe in the default display configuration

6 On the View menu, click Named Views.

7 Double-click Mech. Room, and click OK.

The mechanical room is now the current view. You zoom in so that you can see how the display of each object changes when you change the dis-play configuration in the drawing.

8 Open the Pipe tool palette and click the Add Pipe tool.

NOTE If you are prompted with the No Default Part Set warning dialog box, click Choose a Part, and then click OK to accept the default part.

9 Draw a horizontal pipe segment in the center of the room, as shown.

The pipe is displayed in 1 Line, based on the default display configuration of ABS Floor.

10 Press ENTER to end the command.

Next, you change display configurations. Notice how the pipe is displayed in different configurations.

Look at objects in various display configurations

This drawing uses AEC objects for doors, walls, windows, and stairs. AEC objects can be shown differently as controlled by the display configura-tion. Besides controlling how AEC objects display in different plan views, the display configuration controls how objects display when you change view directions. Notice that the pipe you added is displayed in 1 Line.


Notice the walls, doors, and stairs are gray. Their color is controlled by the display control inherent in objects. The walls and stairs use a display rep-resentation called Screened, which changes them to gray.

NOTE The Screened display representation is unique to the Aecb tem-plates. It causes most architectural AEC objects to be grayed out (screened), by forcing them to use the layer A-Anno-Scrn for their color. If your office uses a different color to plot screened objects, you can modify layer A-Anno-Scrn to use your office standard color for screened architectural backgrounds.

The plumbing fixtures and the elevator are specialized objects called Multi-view Blocks (MvBlocks). They are displayed in the colors associated with their assigned layers. Although they are AEC objects, they do not use the same display control as other AEC objects.

11 Click the Model tab to switch to the model layout.

The Model tab displays these objects in different colors and as 2D objects. If you exploded this drawing now, it would be made up of 2D lines and arcs.

12 On the Navigation toolbar, click on the Views flyout.


Notice that the walls, doors, and stairs are three-dimensional (3D) when viewed from this angle.

13 Click Undo in the toolbar to restore the previous view.

14 Click the Display Configuration list in the lower-right corner of the draw-ing window, and click ABS Ceiling.

Notice that the walls, doors, and stairs are gray, as appropriate for a screened drawing. The ceiling grid is displayed, as you would expect in a Ceiling configuration. Also notice that all objects, including the pipe you added, are displayed in 1 Line.

15 Click the Display Configuration drop-down list, and click ABS Floor - 2 Line.

Notice that the ceiling grid is not shown and that all objects, including the pipe you added, are displayed in 2 Line.

NOTE A key difference between AutoCAD® entities and AEC objects is that AEC objects have predefined display representations that control their


appearances in a designated model space. For example, AEC architectural objects display in 3D when working in a 3D view, in 2D when working in plan view, and gray when displayed as screened elements. The AEC templates pro-vide display representations together with a set of associated display config-urations. A display configuration contains one or more display sets that con-trol the representation of objects in your drawing when viewed from different directions.

Create a snapshot of the current layer settings to use as a reference

While some work is done for you by Display Manager, you will still find layer control useful. Layer Manager gives you the ability to control layers directly and manage layers more efficiently. It includes a feature to capture a drawing’s current layer settings in a snapshot.

16 Click the Display Configuration list, and click ABS Floor.

In the ABS Floor display configuration, pipe is displayed in 1 Line.

17 On the Navigation toolbar, click on the Zoom flyout.

18 On the Format menu, click Layer Management ➤ Layer Properties Man-ager.

19 Click .

20 Click New, and enter Original for Snapshot Name.

21 Click OK.

NOTE When you create a snapshot, you store the current settings of all lay-ers in the drawing. If you change layer settings, colors, and linetypes, you can restore the original settings by clicking Snapshots, selecting Original, and clicking Restore and OK. You can also import the layer settings of an existing drawing into a new drawing. Using this approach can reduce setup time and help to maintain consistency.

Create a filter group to control objects in a drawing

By creating a filter group for the architectural plumbing fixtures and the elevator cores, you can control these layers directly. A filter group can be used for these different types of objects because they are all on layers that begin with “A-flor.” You can use a filter group that captures all layers beginning with “A-flor” and ending with any characters, as represented by the * wildcard character.

The plumbing fixtures in Autodesk Building Systems have intelligent con-nectors that are used by the schematic pipe objects. Architectural plumb-


ing fixtures do not have these smart connectors. By creating a filter group that contains the architectural fixture layer, you can control the graphical display for the layer. In this case, you hide the architectural fixtures to pre-pare for placing Autodesk Building Systems plumbing fixtures in the draw-ing.

22 In the left pane of Layer Manager, verify that All is selected.

23 Click .

24 Enter ArchFixtures for Filter Name.

25 In the box that contains an asterisk, enter m_A-FP-01_P1|A-flor*, inserting the pipe character between the P and A by pressing SHIFT + \.

26 Click OK to close the Layer Filter Properties dialog box.


The ArchFixtures filter group is shown in the left pane of Layer Manager.

27 In the right pane of Layer Manager, click the light bulb next to the m_A-FP-01_P1|A-Flor-P-Evtr layer to turn off the display of the elevators.

28 Right-click any layer name, and click Select all.

29 In the Color column, click the color assigned to any layer.

30 In the Select Color dialog box, enter 8 for Color.

Lesson 2: Specifying Drafting and Design Preferences | 15

31 Click OK twice to close Layer Manager.

32 On the View menu, click Regen to regenerate the drawing and see your changes.

All architectural drawing layers are now displayed in the background (screened) color and the elevators are hidden.

NOTE You can create static or dynamic filter groups, as well as user-defined filter groups. Once a group has been created, you can lock or unlock the group, or turn on or off all layers within the group. To do this, right-click the group in the left pane of Layer Manager and click the appropriate command.


In this exercise, you inserted an external drawing into your current draw-ing in order to reference the AEC objects in the floor plan. Using Layer Manager, you created a static filter group to isolate and control the display of specific layers, and to create a snapshot of the current layer settings. Next, you are introduced to the drawing preferences that are crucial to working with the Plumbing module of Autodesk Building Systems.

Lesson 2: Specifying Drafting and Design Preferences

The exercises in this lesson introduce you to the preferences you can specify to define your drawing environment. Autodesk Building Systems preferences are the drafting and design defaults that you can specify on a drawing-by-


drawing basis, or share between multiple drawings through styles or tem-plates.

Autodesk Building Systems has two types of preferences: initialization and layout. Initialization preferences are typically specified at the start of your design, are based on project standards, and generally do not change through-out the design process. These preferences, which include fundamental ele-ments such as design elevations, are addressed in this lesson. Layout prefer-ences, which are based on specific drafting or design requirements, can be set when you add plumbing fixtures and schematic pipe to your design. They include design-specific elements such as labeling schematic pipe with flow arrows as you draft.

This lesson covers the key initialization preferences for the Plumbing mod-ule: design elevations, default part catalogs, and tooltips. The exercises in this lesson introduce you to preferences that you can specify to define your draw-ing environment.

NOTE In order to perform the exercises in this tutorial, you must use the set-tings specified in this lesson. As you complete the lesson, you may find that the values in your software already match the values specified here. This is because many of the default settings that are part of a standard installation of Autodesk Building Systems are used in this tutorial.


■ Exercise 1: Specifying Design Elevations

■ Exercise 2: Specifying Default Part Catalogs

■ Exercise 3: Specifying Tooltips

Exercise 1: Specifying Design Elevations

In Autodesk Building Systems, you can define named elevations that your parts can use during layout. You can save elevations for different systems on the same floor or on multiple floors in a single building.

Generally, when you start a drawing for a new project, you know the approx-imate heights for the equipment and plumbing runs. This exercise shows how to define the elevations to use for part placement in your drawing. These elevations will be available when you add fixtures and schematic pipes later in the tutorial.



Establish elevations for fixtures

1 On the Format menu, click Options.

2 In the Options dialog box, scroll to the right and click the Building Sys-tems Elevations tab.

3 Click .

4 Click New Elevation, and enter Basin for Name.

5 Click the elevation value, and enter 850 mm for Elevation.

6 Repeat this procedure to create another new elevation. Enter Drinking Fountain for Name, and 1000 mm for Elevation.

7 Click OK to close the Options dialog box.


9 Click the Elevation list to see the elevations you added.


10 In the Add Schematic Pipes dialog box, click Close.


In this exercise, you defined elevations that your parts can use during lay-out. Next, you specify the default catalogs to use for part selection during layout.

Exercise 2: Specifying Default Part Catalogs

Autodesk Building Systems catalogs are libraries of industry-specific, real-world parts. To make it easier to find parts, the parts are organized into chap-ters. Each chapter of a part catalog contains a collection of similar parts, listed alphabetically. For example, all basins, such as 375 x 375 mm Rectan-gular Basin UK, are stored in the Basins chapter of the Plumbing part catalog. Examples of other chapters are: Drains, Fountains, Toilets, and Tubs. Style-based content refers to parts that derive their property information from style definitions rather than from catalog files. All content is organized by type, such as schematic symbols.

You can use part catalog preferences to specify default part catalogs from which parts can be selected during layout. The parts you need for this tutorial are in the catalogs that are designated during a standard installation of Autodesk Building Systems. After you become more familiar with the soft-ware, you can customize the catalogs or create new ones. For example, your office might have developed its own catalog, or you might use a preferred vendor that provides its own catalog.

This exercise shows how to specify catalogs from which parts can be selected for placement in the drawing. The catalogs listed in this exercise must be selected as the default catalogs in order to complete the remaining exercises in this tutorial.

5 Verify that the MvParts catalog is All Installed MvParts UK. If a different catalog is specified, click the [...] button and specify the path as c:\Docu-ments and Settings\All Users\Application Data\Autodesk\ABS 2005\enu\Aecb Catalogs\MvParts UK\All Installed MvParts UK.apc.

6 Verify that the Schematic Symbols path is c:\Documents and Settings\All Users\Application Data\Autodesk\ABS 2005\enu\Aecb Content\Schematic UK\. If a different path is specified, click the [...] button and specify the correct path.

7 Verify that the Schematic Pipe Fittings path is c:\Documents and Set-tings\All Users\Application Data\Autodesk\ABS 2005\enu\Aecb Con-tent\Plumbing UK\. If a different path is specified, click the [...] button and specify the correct path.

8 Verify that the Shared Content path is c:\Documents and Settings\All Users\Application Data\Autodesk\ABS 2005\enu\Aecb Shared Content\. If a different path is specified, click the [...] button and specify the correct path.




In this exercise, you specified the default catalogs from which you can select parts. Next, you work with tooltips.

Exercise 3: Specifying Tooltips

Tooltips display a description when you pass your cursor over items such as toolbars and icons. Tooltips are helpful during design layout because they provide information about an object quickly. Using tooltips in Autodesk Building Systems, you can identify the name of an object, the system the object belongs to, and how the object is classified. In this exercise, you verify that tooltips are turned on.


View tooltip options


2 Click the Building Systems Tooltips tab.

3 Verify that Object Name, System, and Elevation are selected.



5 In the drawing, hover the cursor near the intersection of the fixture and the pipe run to see the tooltips.

This tooltip identifies the objects names and elevations.


Initialization preferences are your drafting and design defaults that con-trol the overall operation of Autodesk Building Systems. They may be cus-tomized for your office, but for the purposes of this tutorial, they must remain at the settings established in this lesson. As you add plumbing fix-tures and pipe to your drawing in the next few lessons, you will see how these settings control your drawing environment.

Before you begin drafting, you need to set up the plumbing tables that will be referenced as you add fixtures to your drawing, and when you size your systems. These tables are addressed in the next lesson.

Lesson 3: Creating Plumbing Tables

In Autodesk Building Systems’ Plumbing module, there are three tables that must be defined at the beginning of your project if you plan to do any pipe sizing for the supply and sanitary waste systems in your design: the fixture unit table, the supply pipe sizing table, and the sanitary pipe sizing table. Each of these tables must be customized to conform to the applicable plumb-ing codes for your locality and to meet project-specific requirements. The verification and proper use of the values in these tables is essential to pipe sizing in the Plumbing module.

When you add fixtures to your design, the software refers to the fixture unit table you have selected and assigns the proper fixture unit values to the sup-ply and sanitary waste connectors on the fixtures. Later, when you size a pipe

Lesson 3: Creating Plumbing Tables | 23

run, the software calculates the total number of fixture units for the run, and uses this total in determining the proper pipe size. When you size a supply or sanitary waste system, you specify the supply or sanitary waste pipe sizing table that you want the software to use to perform its calculations. These tables are established at the beginning of a project and used throughout the project.

In this lesson, you view the contents of the Standard tables that are supplied as samples in the Plumbing module, and then create project-specific tables that will be used in the drafting and pipe sizing exercises in this tutorial.

Exercise 1: Creating a Fixture Unit Table

This exercise shows how to define a fixture unit table for use with your sam-ple project. A fixture unit table definition that meets your local code and project requirements is essential to supply pipe sizing in the Plumbing mod-ule. If you plan to do any pipe sizing for supply or sanitary waste systems in a project, you should establish the fixture unit table that you need at the beginning of the project. When you add fixtures to your plumbing design, you specify the fixture unit table that you want the software to use. As fix-tures are added to your drawing, the software refers to the specified fixture unit table and assigns fixture unit values to each of the connectors on the fix-ture, based on the name of the fixture being added and the occupancy type (private or public). When you size a pipe run, the software calculates the total number of fixture units for the run, and uses this total to determine the proper pipe size.

A standard fixture unit table is provided in the Plumbing module that you can use as a guide in creating a fixture unit table that meets your code and project requirements. If you choose to use the Standard fixture unit table, you should verify that the values meet your design requirements.

You can follow the same procedure to create your own office standard fixture unit table or project-specific fixture unit tables.

Exercise 2: Creating a Supply Pipe Sizing Table

This exercise shows how to define a supply pipe sizing table for use with your sample project. A supply pipe sizing table definition that meets your local code requirements is essential to supply pipe sizing in the Plumbing module. If you plan to do any pipe sizing for a supply system in a project, you should establish the supply pipe sizing table that you need at the beginning of the


project. When you size your supply systems, you specify the supply pipe siz-ing table that you want the software to use.

A standard supply pipe sizing table is provided in the Plumbing module that you can use as a guide in creating a supply pipe sizing table that meets your code and project requirements. If you choose to use the Standard supply pipe sizing table, you should verify that the values meet your design require-ments.

Exercise 3: Creating a Sanitary Pipe Sizing Table

This exercise shows how to define a sanitary pipe sizing table for use with your sample project. A sanitary pipe sizing table definition that meets your local code requirements is essential to pipe sizing in the Plumbing module. If you plan to do any pipe sizing for a sanitary waste system in a project, you should establish the sanitary pipe sizing table that you need at the beginning of the project. When you size your sanitary waste design, you specify the san-itary pipe sizing table that you want the software to use.

A standard sanitary pipe sizing table is provided in the Plumbing module that you can use as a guide in creating a sanitary pipe sizing table that meets your code and project requirements. If you choose to use the Standard sanitary pipe sizing table, you should verify that the values meet your design require-ments.

The sanitary pipe sizing table contains three tabs for different types of pipe runs: Stacks, Branches, and Offsets. When you size a pipe run, you specify the type of run being sized. The type of run you select determines which tab of the sanitary pipe sizing table is referenced. For example, if you specify that the run you are sizing is a branch, then the software refers to the information on the Branches tab of the sanitary pipe sizing table you have selected for use.


View the Standard sanitary pipe sizing table

1 In the drawing, right-click, and click Plumbing ➤ Sanitary Pipe Sizing Table Definitions.


3 Click the Stacks tab.


4 Notice that the table defines the maximum fixture unit load for each stack diameter, according to the number of stories in the building.

NOTE In the Standard sanitary pipe sizing table, the fixture unit values are the same for buildings with three or less stories and buildings with more than three stories. These values may vary according to local codes. If your local code specifies different values, you can edit the Standard sanitary pipe sizing table or create a new sanitary pipe sizing table to meet your requirements.

When sizing a stack in the Plumbing module, you select the sanitary pipe sizing table you want to use and the number of stories the stack spans. Based on this information and the number of fixture units calculated for the selected stack, the software references the specified sanitary pipe sizing table and determines the stack diameter.

5 Click the Branches tab.


6 Notice that the table defines the maximum fixture unit load for each pipe diameter.

When sizing a sanitary pipe run in the Plumbing module, you select the sanitary pipe sizing table you want to use. If you specify that the run you are sizing is a branch, then the software refers to the information on the Branches tab of the sanitary pipe sizing table you have selected for use.

Creating a Plumbing Design

After you have set the standards and preferences for

your project, you are ready to start drawing. Whether

you draft by hand, with AutoCAD® 2005, or with

Autodesk® Building Systems, the process of creating a

plumbing design follows the same workflow: you place

the plumbing fixtures, locate the water supply and san-

itary waste exit, and connect the fixtures with pipes.

Within the framework of this familiar workflow, this

chapter introduces you to the advantages of creating a

plumbing design with the specialized objects in the

Plumbing module of Autodesk Building Systems.

In the Plumbing module, fixtures, pipes, and fittings are

intelligent objects that work together. This chapter

shows you how to place these objects in your drawing

and how to modify their properties.

Lesson 4: Adding Plumbing Fixtures

The first step in creating a plumbing design is to place the plumbing fixtures. In AutoCAD, you might draw a water closet or sink with lines, but more com-monly, you would use a set of AutoCAD blocks to represent these fixtures. Autodesk Building Systems provides a library of specialized, multi-view AutoCAD blocks called MvParts (Multi-view Parts). These parametric or block-based parts represent fixtures and parts such as pumps and water heat-ers.

The extensive collection of MvParts is arranged into type-specific families called catalogs. You retrieve industry-specific equipment from the catalogs and integrate it into your design. For example, to place a basin in your draw-ing, you select the part from the Basins folder of the Plumbing MvPart cata-log.

MvParts relate intelligently by recognizing the size, style, shape, or type of object being attached or connected. When you place a fixture in your draw-ing, you are placing an MvPart that will connect intelligently with other parts within its group of parts.

The connectors on MvParts do several things: they provide snap points that allow pipe to attach readily to the MvPart; they pass sizing and orientation information to the pipe; and they hold the fixture count, so that when you are ready to prepare a fixture schedule, the information you need is already in the drawing.

The exercises in this lesson show how to add various plumbing fixtures to your drawing using object snap points, object tracking, and the Compass to guide you. Because you place the fixtures using tracking from AEC objects, the fixtures are inserted at an elevation of 0, which is the elevation read from the starting point of the tracking vector. In a later exercise, you use the ele-vations you created in chapter 1 of this tutorial to place the basins and uri-nals at the proper elevations.

5 Click the Fixture Units tab.

6 Select Tutorial Standard for Fixture Unit Table.

7 Verify that Fixture is Sink - Washup, and Occupancy is Public.

8 Click the pushpin in the upper-right corner of the Add MvParts dialog box to minimize the dialog box to its title bar.

When you move the cursor off the dialog box, you get an unobstructed view of the drawing area, making it easier to place objects. After you


enable the pushpin feature, all Add and Modify dialog boxes display this behavior.

After clicking the pushpin, you can work in the drawing area without clicking in the area first. The dialog box is redisplayed when you move the cursor over the title bar.

9 Specify the drafting settings:

■ On the status bar, right-click Osnap, and click Settings.■ Verify that Object Snap On and Object Snap Tracking On are selected.■ Click Clear All.■ Select Intersection, and click OK.


NOTE When you insert plumbing fixtures into your drawing, you use the Compass to properly orient them. If you find that the color of the Compass is too light for easy viewing on a white background, you can change the Compass color by clicking MEP Common ➤ Compass ➤ Compass Settings, selecting the desired color, and clicking OK.

10 Use tracking to place two basins in the countertop in the women’s bath-room in the lower right of the drawing:

■ To the right of the number 1, move the cursor over the point where the countertop meets the wall. Pause over the point where you see an Inter-section snap display.

■ Move the cursor to the right until a tracking vector displays.


Object tracking allows you to track from an osnap point, in this case, an Intersection osnap. The tracking vector displays as a dashed line when you move the cursor away from the osnap point.

■ Enter 800 mm, and press ENTER.■ In the drawing, use the Compass to rotate the basin to 90 degrees, and

click to place it.


■ Move the cursor to the left, enter 800 mm, and press ENTER.■ Use the Compass to rotate the basin to 90 degrees, and click to place it,

as shown.

The basins are placed 800 mm from each end of the countertop at a rotation of 90 degrees.

11 Use tracking to place two basins in the countertop in the men’s bathroom:


■ Move the cursor up, enter 500 mm, and press ENTER.■ In the drawing, use the Compass to rotate the basin to 180 degrees, and

click to place it.■ To the right of the number 4, move the cursor over the point where the

countertop meets the wall. Pause over the point where you see an Inter-section snap display.

■ Move the cursor down, enter 500 mm, and press ENTER.


■ Use the Compass to rotate the basin to 180 degrees, and click to place it.


The basins are placed 500 mm from each end of the countertop at a rotation of 180 degrees.


In this exercise, you placed basins in your drawing using object snap points, object tracking, and the Compass to guide you. You selected the specified basin from the Add MvParts dialog box. Because you selected the Add Sink tool from the palette, the list of parts displayed in the Add MvParts dialog box was limited to those MvParts that are defined as Sink in the Type field. Next, you use the Add MvParts dialog box to insert addi-tional plumbing fixtures in your drawing.

Exercise 2: Adding Toilets and Urinals

This exercise shows an efficient method for placing MvParts from different part families in your drawing. The toilets and urinals have cold water and drain connections to be used when adding pipe runs.


Select and place toilets

1 Open the Plumbing Equipment tool palette and click the Add Water Closet tool.

2 Select Wall-Mounted Flush Valve Toilet UK.

3 Select UCS for Elevation.


Because you have selected the Add Water Closet tool, the Add MvParts dialog box displays only the water closet section of the MvParts catalog.


5 Verify that Fixture Unit Table is Tutorial Standard.

6 Resize the dialog box to see the full name for Fixture.

To do this, hover the cursor over the lower-right corner of the dialog box until the cursor becomes a double-headed arrow, and then drag the corner of the dialog box to the right until the full name of the fixture is displayed.

7 Select Water Closet - Flushometer Valve for Fixture, and Public for Occu-pancy.


When you change the fixture, the fixture units are read from the Tutorial Standard fixture unit table, and the value for Connector 1 (the supply con-nector) changes from 2.50 to 5.00 fixture units.

NOTE When you select a fixture in the Add MvParts dialog box, the soft-ware refers to the specified fixture unit table to retrieve the fixture unit values for the fixture. The fixture unit table is referenced based on the name and occupancy type of the fixture. In some cases, the names of fixtures are similar, and the software retrieves the information for the first closely-matched fixture name. You must verify that the proper fixture has been referenced. If you change the fixture, the fixture units are updated as well. If you select a fixture that has no fixture unit assignment, such as a washing machine, the Fixture Units tab displays so that you can enter fixture unit values.

8 Verify the drafting settings:

■ On the status bar, right-click Osnap, and click Settings.■ Verify that Object Snap On and Object Snap Tracking On are selected.■ Verify that only the Intersection mode is selected, and click OK.

9 Use tracking to place four toilets in the women’s bathroom:

■ To the right of the number 5, move the cursor over the point where the walls intersect between the accessible handrails. Pause over the point where you see an Intersection snap display.

■ Move the cursor up until a tracking vector displays.


The tracking vector displays when you move the cursor away from the osnap point.

■ Enter 500 mm.■ In the drawing, use the Compass to rotate the toilet to 0 degrees, and

then click to place it.

■ Move the cursor up along the wall behind the toilet in the accessible stall until you reach the stall partition. Pause over the point where you see an Intersection snap display.

■ Move the cursor up, and enter 400 mm.■ Use the Compass to rotate the toilet to 0 degrees, and click to place it,

as shown.


The first two toilets are placed in the women’s bathroom.

■ Use the same procedure to place two toilets in the empty stalls in the women’s bathroom, as shown.

All four toilets are placed in the women’s bathroom.

■ Use the same procedure to place two toilets in the enclosed stalls in the men’s bathroom. For the accessible stall, place the toilet 500 mm from the intersection to the right of number 6, at a rotation of 180 degrees. For the next stall, place the toilet 400 mm from the stall partition at the same rotation, as shown.

NOTE If you close the Add MvParts dialog box and start the command again, click the Fixture Units tab and change the fixture to Water Closet - Flushometer Valve before placing the toilets in the men’s bathroom.


Two toilets are placed in the men’s bathroom and the Add MvParts dialog box remains open.


Select and place urinals

11 On the Plumbing Equipment tool palette, click the Add Urinal tool.

12 Select Urinal Stall UK.



15 Verify that Fixture Unit Table is Tutorial Standard, Fixture is Urinal, and Occupancy is Public.


16 Following the same procedure you have been using, add two urinals to the drawing. Place the fixtures 400 mm from the stall partitions, as shown.

The urinals are placed in the drawing.


NOTE You can calculate pipe sizing values at any time in the design phase of your project, even before you have added schematic pipe. On the MEP Common menu, click Plumbing ➤ Sanitary Pipe Sizing Calculator, add known values, and press ENTER to calculate the pipe size. You can also size supply pipe using the Supply Pipe Sizing Calculator.


In this exercise, you used the Plumbing Equipment tool palette to access individual sections of the MvParts catalog. Use this tool palette to insert several different types of parts. Use a filtered list, as you did in the previous exercise, when you want to insert only one type of MvPart. Knowing when to use a filtered list instead of the full catalog can help you work more quickly and efficiently.

In addition to working with part selection in this exercise, you also con-tinued using object snap points, object tracking, and the Compass for part placement. Next, you use coordinates to place the final MvParts in your drawing.

Exercise 3: Adding Floor Drains and Drinking Fountains

This exercise shows how to place objects in your drawing using coordinates. Like the other MvParts you have added to your design, the floor drains and


drinking fountains you add in this exercise have “smart connectors” to be used when adding pipe runs.


Place floor drains using coordinates

1 Open the Plumbing Equipment tool palette and click the Add Plumbing Equipment tool.

2 Expand the Drains folder, and select Round Floor Drain UK.


4 Click Details.

The available sizes of floor drains in the catalog are displayed.

5 Select 125 mm Round Floor Drain.


7 Verify that Fixture Unit Table is Tutorial Standard, Fixture is Floor Drain, and Occupancy is Public.

8 Place the drains by specifying the following coordinates:


■ Enter 35800,17500, and press ENTER.■ Press ENTER to place the drain at the default rotation angle.■ Enter 39200,17500, and press ENTER.■ Press ENTER to place the drain at the default rotation angle, as shown.

The floor drains are placed in the bathroom floors at the specified coordinates and the Add MvParts dialog box remains open.

Place drinking fountains using coordinates

9 On the status bar, verify that Ortho is turned off.

10 In the Add MvParts dialog box, click the Part tab.

11 Expand the Fountains folder, and select Round Wall-Mounted Drinking Fountain UK.

12 Select Drinking Fountain for Elevation.


14 Verify that Fixture Unit Table is Tutorial Standard, Fixture is Drinking Fountain, and Occupancy is Public.

15 Place the fountains by specifying the following coordinates:

■ Enter 27000,24300 for the insert point, and press ENTER.■ Enter 45 degrees for the rotation angle, and press ENTER.■ Enter 33200,17500 for the insert point, and press ENTER.■ Enter 225 degrees for the rotation angle, and press ENTER.


The fountains are placed at the specified elevation and locations in the break area and corridor.



In previous exercises, you placed MvParts by tracking from Intersection osnap points that set the elevations for the fixtures at 0. In this exercise, you placed MvParts using coordinates to specify the insertion points, which allowed you to insert the parts at predefined elevations.

You have finished adding fixtures to your plumbing design. Next, you modify fixture properties (to adjust fixture units and elevations), define a new system, and set pipe preferences as you prepare to add the plumbing pipes to your design.

Lesson 5: Working with Plumbing Systems

The exercises in this lesson set the stage for the completion of your plumbing design. Before you can run the plumbing pipes to connect the fixtures, you need to analyze your design and make necessary adjustments. First, you review the fixture units assigned to the fixtures you placed in the drawing and modify these values to suit the design needs of the sample project.

Lesson 5: Working with Plumbing Systems | 55

Each connector on a fixture has an associated fixture unit value that is used for pipe sizing. The fixture unit value is derived from the specified fixture unit table (in this case, Tutorial Standard), which defines fixture require-ments based on plumbing building codes. Typically, the CAD manager in your office creates a fixture unit table that conforms to local plumbing codes and your preferred manufacturers’ specifications for the fixtures that you use in your drawings.

As you add fixtures to your drawing, they are automatically assigned fixture units. The default fixture unit values are derived from the specified fixture unit table, based on the name and occupancy type of the fixture being added. The default fixture unit values suit the fixture requirements of many design situations; however, they will not be the correct values for all plumbing designs. For this sample project, you modify the fixture unit values for the toilets in your drawing.

After modifying the fixture units, you make another project-specific adjust-ment: you define a new system to be used for gas piping, fittings, and equip-ment. The plumbing requirements for this sample project call for a gas sys-tem for the water heater; however, the template you are using does not include the system definition you need.

As the final step in preparing to add pipes to your design, you set the prefer-ences for the schematic pipe you will use. In the Plumbing module, pipe is called schematic pipe because it is a two-dimensional (2D) object that holds system and style information, which control how it displays and how it con-nects with other objects in your drawing. Unlike the pipe object in the Mechanical module, schematic pipe does not have a 3D display representa-tion.

■ Exercise 3: Preparing to Work with Schematic Pipe

Exercise 1: Modifying Fixtures

In the Plumbing module, each connector on a fixture has an associated fix-ture unit value that is used for pipe sizing. Because the default fixture unit values may not be the correct values for all design situations, they should be reviewed and adjusted to suit the requirements of your design. In this exer-cise, you increase the toilets’ supply pressure in order for their flushometer valves to work at maximum efficiency. This exercise shows you how to mod-ify the default supply and drain fixture units for the toilets.



Change the toilets’ fixture units

1 Select any toilet in the drawing, right-click, and click MvPart Properties.


3 Verify that Fixture is Water Closet - Flushometer Valve.

4 Enter 6.00 for Fixture Units for Connector 1.

5 Enter 5.00 for Fixture Units for Connector 2.

6 Click OK to close the MvPart Properties dialog box.

7 Select the remaining toilets in the drawing, and use the same procedure to change their supply and waste fixture units.

Change the elevations for the basins and urinals

Because you placed the basins and urinals using tracking from AEC objects, they are inserted at an elevation of 0, which is the elevation read from the start point of the tracking vector. To move these fixtures to their proper heights, you use the MvPart Modify command. For the basins, you select the predefined Basin elevation created in chapter 1 of this tutorial. For the urinals, you enter a dimension value for Elevation.


8 Select the four basins in the drawing.

9 Right-click, and click MvPart Modify.

10 Select Lavatory for Elevation, and click OK.

The four basins are moved to the Basin elevation of 850.0 mm.

11 Select the two urinals in the drawing.

12 Right-click, and click MvPart Modify.

13 Enter 500 mm for the elevation value, and click OK.

The two urinals are moved to a height of 500 mm.



In this exercise, you adjusted the default fixture unit values in your plumbing design in preparation for sizing the pipes later in this tutorial. You also adjusted the elevations for the fixtures that you placed using tracking. Next, you create a plumbing system definition to use for gas pip-ing, fittings, and equipment.

Exercise 2: Defining Plumbing Systems

This sample project requires gas piping for the water heater; however, the template you are using does not include a system definition for a gas system. This exercise shows how to create your own system definitions to meet the design requirements of your projects.

It is important to define the system types to be represented in your drawing before you add schematic pipes. As you draft your schematic pipe runs, you select a system from the Add Schematic Pipes dialog box. The information in the system definition prevents connections between different system types, holds the variables that set the layer for the pipe, and contains an abbrevia-tion that can be used to label the pipe.

Systems can be grouped together to make it easier to manage similar systems. For example, if you are designing a cold water supply system, you can create a separate cold water supply system for each floor of a building, and then group the individual systems together as one complete cold water supply sys-tem for the whole building.



Create a new style and define general system information

1 In the drawing, right-click, and click Plumbing ➤ Plumbing System Defi-nition.

2 In the right pane of Style Manager, right-click, and click New.

3 Enter Gas for the name of the new style.

4 Double-click the Gas style to edit it.

5 On the General tab, enter Gas Piping for Description.

Define default fittings

6 Click the Defaults tab.


As you draw and connect schematic pipes, fittings are inserted automati-cally to connect the segments and runs. The correct fitting is inserted based on the schematic fitting defaults that you specify in the system def-inition. There are four types of schematic pipe fittings that are placed automatically as you draw: elbows, tees, crosses, and transitions. You can import a specific fitting to be used for each fitting type. Because the soft-ware has the ability to draw elbows dynamically based on the direction of your pipe run, there is no import option for Elbow.

7 Click Import to the right of Tee.

8 Select Plumbing Fittings UK.

9 Click the Tees category.

10 Scroll down, select Tee, and click OK.


11 Click Import to the right of Tee Up.

12 Select Tees, select Tee Up, and click OK.

13 Click Import to the right of Tee Down.

14 Select Tees, select Tee Down, and click OK.

15 Click Import to the right of Cross.

16 Select Crosses, select Double Swept Tee, and click OK.

17 Click Import to the right of Transition.

18 Select Transitions, select Concentric Transition, and click OK.


As you draw and connect schematic pipes, these default fittings will be inserted automatically to connect the segments and runs.

Define design rules for the system

19 Click the Design Rules tab.

20 Enter GAS for Abbreviation.

This is the text that is used by the System label style when labeling a sche-matic pipe.

21 Enter GAS for System Group.

22 Select Gas for System Type.

23 Double-click in the Override Value column next to Major, and enter Fuel for the major field of the layer key override.

24 Double-click in the Override Value column next to Minor 1, enter Gpip for the minor field of the layer key override, and press ENTER.


Define display properties for the system

25 Click the Display Properties tab.

26 Click Style Override.

27 Click the light bulb next to Connector to turn off tick marks for this com-ponent.

If the light bulb is blue, the tick marks are turned off.

28 Click OK three times to close Style Manager.



In this exercise, you created a plumbing system definition to use for gas system piping, fittings, and equipment. Next, you define the graphical appearance of schematic pipe.

Exercise 3: Preparing to Work with Schematic Pipe

You have the option of having labels and flow arrows automatically placed along your schematic pipe runs as you draft. As you begin using the Plumb-ing module, you may want to turn on the automatic labels to view flow direc-tion. Proper flow direction is critical to pipe sizing. If you want to view labels or flow arrows for the pipe run, turn them on before you add schematic pipe.

Several label styles are available for use: Standard, which displays the line size as label text; System, which displays the system abbreviation; and Name, which displays the pipe style name. Flow arrow styles are also available to you.

In this tutorial, the automatic labels are not used, so that you can add anno-tation to your drawing separately. After you complete your plumbing design in this chapter of the tutorial, the next chapter shows how to add flow arrows, labels, and other annotation to your drawing.


Set preferences for schematic pipe

1 Open the Plumbing tool palette and click the Schematic Pipe Preferences tool.

2 Verify that Apply Labels/Flow Arrows is cleared in both locations, and click OK.



In this exercise, you turned off automatic labels and flow arrows so that you can add them manually later in the tutorial.

You have completed the tasks necessary to prepare your plumbing system for schematic pipe. Next, you add pipes and fittings to create a cold water system and a sanitary waste system.


Lesson 6: Adding Schematic Pipe

Traditionally, after the fixtures are located in the drawing, you reset the layer to a piping layer, and start drawing lines that represent pipes connecting the fixtures. Next you add the risers and fittings, which requires extensive trim-ming and filleting of the layout.

In Autodesk Building Systems, the process of adding pipes and fittings to a drawing is far simpler than the traditional method. First, Autodesk Building Systems automatically layers the objects you are using; therefore, when you start drawing the pipes, you do not need to change your current layer. Another advantage is the Plumbing module’s use of schematic pipe objects, rather than AutoCAD lines, to draw your pipe runs. Schematic pipe contains much more information than an AutoCAD line. Like the MvParts you used in an earlier lesson, schematic pipe has properties and smart connectors. Schematic pipe carries information about what system it belongs to, such as cold water, drains, or sanitary waste. This system definition prevents connec-tions between systems, holds the variables that set the layer for the schematic pipe, and contains an abbreviation that can be used to label the pipe.

Schematic pipe can have different appearances when crossing other seg-ments and can depict rises and drops. It is trimmed automatically when addi-tional pipe segments and fixtures are connected, and it maintains knowledge of flow direction, slope, elevation, and fixture unit load.

Because schematic pipe is an intelligent object, when you change direction or pipe size in a schematic pipe run, the proper fitting is placed in your draw-ing. The fitting is determined by the type of change you make (pipe size or direction) and the system definition applied to the pipe, such as cold water or sanitary waste. In the case of laterals, the elevation also controls place-ment.

Schematic pipe and its associated fittings are style-based content, not MvParts. This means that they derive their property information from Build-ing Systems style definitions rather than from catalog files. You add them using the Schematic Piping and Schematic Pipe Fittings options from the Plumbing tool palette, rather than through the part catalogs. After adding a schematic pipe or fitting to your drawing, you can access its property infor-mation by right-clicking it and selecting either Schematic Pipe Properties or Schematic Fitting Properties.

This lesson shows how to add schematic pipe and fittings for the cold water and sanitary waste systems. It also shows how to review the flow direction of the schematic pipes and make changes as needed. The flow direction of the pipe is critical because it is used by the built-in pipe sizing tools. The supply

pipe sizing tool sizes downstream only, while the sanitary pipe sizing tool sizes upstream only.


■ Exercise 1: Adding Domestic Cold Water Pipes

■ Exercise 2: Adding Fittings to Schematic Pipe

■ Exercise 3: Creating a Sanitary Waste System

■ Exercise 4: Changing the Flow on a Pipe

Exercise 1: Adding Domestic Cold Water Pipes

This exercise shows how to add schematic pipe for the cold water system. Whenever you add schematic pipe, you specify its system, such as Domestic Cold Water. The system definition controls the display properties, layers, and default fittings used in the pipe run, as in the previous lesson when you cre-ated the Gas system definition.

In this exercise, you connect the toilets in the women’s bathroom to the main supply branch, starting with the cold water connection farthest from the source. The men’s bathroom has been done for you. Two changes have been made to the drawing to isolate the fixtures where the pipe will be drawn: the drawing area containing the fixtures has been enlarged, and some layers have been turned off to make it easier to connect the pipe.


Connect a domestic cold water pipe to a toilet

1 On the status bar, right-click Osnap, and click Settings.

2 On the Object Snap tab, click Clear All, and click OK.

TIP Clearing object snaps and keeping Building Systems snaps enabled help to ensure the proper connection of segments.


4 In the Add Schematic Pipes dialog box, select PVC Thermoplastic Pipe for Style.

You do not need to specify values for System, Elevation, or Nominal Size because the values will be read from the connector when you select it in the drawing.


5 Beginning with the toilet nearest the top of the drawing, move the cursor over the back edge of the toilet until a Pipe Connector snap displays, and then click the snap.

6 In the Select Connector dialog box, select Connector 1: Cold Water, and click OK.

NOTE The Select Connector dialog box is displayed only when the connec-tors on a fixture are in the same plane.

7 Move the cursor over the Add Schematic Pipes dialog box.

Notice that values have been filled in for System, Elevation, and Nominal Size, based on the information read from the connector you selected.


8 Enter 2800 mm for Elevation because the supply piping for this sample project will be run between the first and second floors.

9 In the drawing, move the cursor toward the right at 0 degrees, and enter 1500 mm.

10 Move the cursor down to the bottom of the drawing at 90 degrees until a Pipe Curve Connector snap displays on the main supply branch.


11 Click the snap to connect the pipe, as shown.


The fixture farthest from the source is connected to the main supply branch. The elbow and tee fittings are inserted automatically.

Connect the remaining toilets

12 In the drawing, move the cursor over the back edge of the next toilet until a Pipe Connector snap displays, and then click the snap.

13 In the Select Connector dialog box, select Connector 1: Cold Water, and then click OK.

14 In the Add Schematic Pipes dialog box, verify that System is Domestic

Cold Water, and enter 2800 for Elevation.

15 In the drawing, move the cursor toward the right at 0 degrees until a Pipe Curve Connector snap displays on the supply pipe, and click the snap.

16 Use the same procedure to connect the remaining toilets to the cold water supply system, as shown.


The remaining supply pipes are drawn, connecting all of the toilets in the women’s bathroom to the main supply branch.


NOTE In Autodesk Building Systems, you can end an Add command in three different ways: Right-click and click Enter, click Close in the Add dialog box, or press ENTER to end the command from the command line. This tuto-rial introduces all three methods during the course of the exercises. As you become more familiar with the software, you are likely to adopt one method and use it routinely.

Connect a domestic cold water pipe to the drinking fountain

18 On the status bar, turn off Ortho.

19 Right-click Snap, and click Settings.

20 Select Snap On, enter 25 for Snap X spacing and Snap Y spacing, and click OK.


21 On the Plumbing tool palette, click the Add Schematic Pipe tool.

22 In the drawing, click the lower pipe connector on the back of the drinking fountain.

23 In the Add Schematic Pipes dialog box, verify that System is Domestic Cold Water.

If System is Sanitary Black Water, you have selected the upper connector, and must click Close, and then click the Add Schematic Pipes tool before you select the lower connector.

24 In the drawing, move the cursor toward the upper right at 45 degrees, and enter 300 mm to add a segment of pipe at a 45-degree angle into the wall.


25 In the Add Schematic Pipes dialog box, enter 2800 mm for Elevation.

26 In the drawing, move the cursor down at 90 degrees, and select a point just above the column.

27 Move the cursor to the lower left at 120 degrees, and select a point just past the column.

28 Move the cursor down at 90 degrees, and select a point above the main supply line.

The 60 degree fittings are added automatically.


29 In the Add Schematic Pipes dialog box, select 25.0 mm for Nominal Size.

You can increase the size “on the fly” and the transition fitting is added automatically.

30 In the drawing, move the cursor down at 90 degrees until a Pipe Curve Connector snap displays on the main supply branch. Click the snap to connect the pipe, as shown.

The drinking fountain is connected to the main supply branch, and the transition and tee fittings are added automatically.

Notice that the fittings are placed for you even if you use the Compass and 60 degree turns. While there are several ways to route this pipe run, this solution was chosen to demonstrate the automatic insertion of 60-degree angle fittings.



In this exercise, you added schematic pipe to connect plumbing fixtures to the main supply branch. You used the Compass to guide the direction of your pipe runs, and two of the Building Systems snaps to help you make valid connections. The Pipe Connector snap helped you connect sche-matic pipe to plumbing fixtures. The Pipe Curve Connector snap helped you connect schematic pipe to existing pipe segments and runs. As you drafted your pipe runs, the proper fittings (elbows, tees, and transitions) were added. These fittings were inserted based on the schematic fitting defaults that are specified in the Domestic Cold Water system definition. Next, you insert additional fittings to complete the design of the cold water supply system.


Exercise 2: Adding Fittings to Schematic Pipe

This exercise shows how to add in-line fittings to schematic pipes. You add gate valves to the pipes supplying the drinking fountain and the water heater, and to the pipe exiting the water heater. You also add a transition fit-ting to the pipe supplying the drinking fountain.


Add a gate valve for the drinking fountain

1 Open the Plumbing tool palette and click the Add Schematic Pipe Fitting tool.

2 Select Plumbing Gate Valves UK for Fittings.

3 Click the Lever category bar to limit the selections to lever fittings.

4 Select Gate Valve Lever.

5 Verify that Justification is Insertion Point.

6 Verify that Specify Rotation on Screen is selected.

You do not need to enter values for System or Elevation in the Add Sche-matic Pipe Fittings dialog box. These values will be read from the pipe on which you insert the gate valve.


7 In the drawing, select a point on the pipe next to the number 1, and then move the cursor up and select a point on the same pipe to set the rotation for the valve, as shown.

The gate valve is added to the supply pipe for the drinking fountain.



Add two gate valves for the water heater

9 Zoom in to the area of the drawing where the water heater is located.

10 On the Plumbing tool palette, click the Add Schematic Pipe Fitting tool.

The last-used settings have been saved, so you can add a gate valve with-out making any selections in the Add Schematic Pipe Fittings dialog box.

11 In the drawing, select a point on the hot water pipe next to the number 2, and move the cursor to the right and select a point on the same pipe to set the rotation for the valve.

12 Repeat this process, adding a gate valve on the cold water pipe next to the number 3 in the drawing, as shown.

The two gate valves are added and the Add Schematic Pipe Fittings dialog box remains open.

Add a transition for the drinking fountain

Next, you add a transition fitting on the pipe supplying the drinking foun-tain. Typically, a drinking fountain needs only a 10 mm supply pipe. Inserting a reducer into the pipe will allow the pipes on either side of the reducer to be sized independently by the built-in pipe sizing tools.

13 In the Add Schematic Pipe Fittings dialog box, select Plumbing Fittings UK for Fittings.

14 Click the Transitions category bar to limit the selections to transition fit-tings.

15 Select Concentric Transition.

16 In the drawing, select a point on the cold water pipe next to the number 4, move the cursor up, and select a point on the same pipe to set the rota-tion for the transition, as shown.


The concentric transition is added to the supply pipe for the drinking fountain.



In this exercise, you added in-line fittings for the drinking fountain and water heater to complete your cold water supply system design. Next, you draft the sanitary waste system using schematic pipe and schematic pipe fittings.

Exercise 3: Creating a Sanitary Waste System

This exercise shows how to add schematic pipe for the sanitary waste system. Whenever you add schematic pipe, you specify the system, such as Sanitary Black Water. The system definition controls the display properties, layers, and default fittings used in the pipe run.

In this exercise, you connect the toilets in the women’s bathroom to the main sanitary waste line, starting with the connection farthest from the sewer exit.

As you add sanitary waste pipe, you specify a slope for proper drainage. When you draw sloped pipe, the software displays a glyph that shows the slope of the pipe as you draft. You can also change from one fitting to another “on the fly” as you draft. This exercise shows how to change fittings using this method, and how to modify an existing fitting to add a cleanout.



Connect a sanitary waste pipe to a toilet

1 On the status bar, verify that Snap, Osnap, Polar, and Otrack are turned off.


3 In the Add Schematic Pipes dialog box, specify the settings:

■ Select Black Pipe for Style.

You do not need to specify values for System, Elevation, or Size, as the correct values will be read from the waste connector on the toilet when you select it.

■ Enter - 11 (negative 11 mm) for Rise, and press ENTER.

The value you enter for Rise works in conjunction with the Run value to determine the slope of the pipe. In this case, the pipe drops 11 mm for every foot it travels, yielding a slope of - 0.7%.

4 In the drawing, move the cursor over the back edge of the toilet numbered 1 until a Pipe Connector snap displays, and click the snap.

5 In the Select Connector dialog box, select Connector 2: Waste, and click OK.


6 Move the cursor to the left at 180 degrees, and select a point near the num-ber 2.

7 Move the cursor toward the top of the drawing at 90 degrees and select a point near the number 3.

As you work in the drawing, notice the glyph showing the direction of the drop.


8 Move the cursor toward the left at 180 degrees, and enter 42000 mm to extend the pipe to the building’s sewer exit, as shown.

The fixture farthest from the sewer exit is connected to the sanitary waste system.


10 Move the cursor along the sanitary waste pipe you just added and notice that the tooltips reveal the elevation changes as the pipe drops.

Connect the remaining toilets

11 Press ENTER to repeat the Add Schematic Pipe command.

12 In the Add Schematic Pipes dialog box, verify the schematic pipe settings:

■ Verify that Style is Black Pipe.■ Verify that Rise is - 11 (negative 11 mm).

13 In the drawing, move the cursor over the back edge of the toilet above the accessible stall in the women’s bathroom until a Pipe Connector snap dis-plays, and then click the snap.



15 In the drawing, move the cursor toward the left at 180 degrees and con-nect to the sanitary waste line using the pipe curve connector.

16 In the Elevation Mis-match dialog box, select Adjust Slope, and click OK.

17 Using the default settings, connect the remaining toilets in the women’s bathroom to the sanitary waste line, as shown.


The sanitary waste pipes connecting the toilets in the women’s bathroom to the main sewer line are added. The default fittings are inserted in the lines.


Change the default fitting

Before connecting the fixtures in the men’s bathroom, you change the default cross to a Double Sanitary Vent Tee to accommodate the pipe con-nections for the men’s bathroom fixtures and the vent system.

19 Right-click in the drawing area, and click Plumbing ➤ Plumbing System Definition.

20 In the left pane of Style Manager, right-click Sanitary Black Water, and click Edit.


21 Click the Defaults tab, and click Import for Cross.

22 Select Plumbing Fittings UK, select Double Swept Tee, and click OK.

23 Click OK twice to close Style Manager.



25 In the Add Schematic Pipes dialog box, click the arrow to the right of Pref-erences, click Cross, and verify that Double Swept Tee is the default.

26 In the men’s bathroom, move the cursor over the back edge of the toilet that is located between the accessible stall and the first urinal. When a Pipe Connector snap displays, click the snap.


28 In the drawing, move the cursor toward the right at 0 degrees, and con-nect to the Pipe Connector snap on the fitting (not the pipe curve connec-tor on the sanitary waste line).

29 In the Elevation Mis-match dialog box, select Adjust Slope and click OK.


The sanitary tee fitting is changed to a double swept tee.

Add cleanouts

31 In the drawing, zoom in to the area near the number 3.



33 Select the Pipe Curve Connector snap at the end of the horizontal pipe as the starting point for the new pipe segment, drag the cursor to the right, and enter 600 mm.

The elbow changes to a tee. In the Plumbing module, fittings change dynamically to accommodate the addition of pipe segments or runs.


35 On the Plumbing tool palette, click the Add Schematic Pipe Fitting tool.

36 Verify that Plumbing Fittings UK is selected for Fittings.

37 Click the All category bar to view all of the plumbing fittings.

38 Select End of Line Cleanout.

39 Select Sanitary Black Water for System.

40 In the drawing, select the pipe curve connector on the pipe segment you just added, move the cursor to the left, and click to set the rotation at 180 degrees, as shown.

The cleanout is added to the drawing.



In this exercise, you connected the toilets in the women’s bathroom to the main sanitary waste line and added fittings using two different methods. Next, you reverse the flow on a pipe.

Exercise 4: Changing the Flow on a Pipe

This exercise shows how to change the flow direction of a pipe. Proper flow direction is essential to pipe sizing. As you add pipes to your drawing, a default flow direction is applied whether or not you use flow arrow labels. When you add a schematic pipe using a connector on a fixture as the starting point, the pipe reads the flow direction from the connector. When you add a schematic pipe to existing schematic pipes, the flow direction is assigned


based on the direction in which the segment is drawn. If the default direction is opposite the actual flow, you can reverse the flow direction by selecting the pipe segment and using the Reverse Flow command. When changing the direction of the flow for a pipe segment or run, you should take into consid-eration the system type, the elevation, and the rise/drop symbology.

In this exercise, the area of the drawing that contains the pipe run to be mod-ified has been enlarged for easier viewing, and flow arrow labels have been added to illustrate the flow direction of the pipes. The flow arrow label style is provided in the template. The steps for applying flow arrow labels are pre-sented later in this tutorial when you annotate your drawing.


Reversing flow direction for pipe segments and runs

1 In the drawing, select the pipe next to the number 1.

2 Right-click, and click Reverse Flow.

The flow direction is reversed for the selected pipe segment only. When establishing a selection set, the Reverse Flow command does not travel beyond a tee.

3 Right-click, and click Repeat SPIPEREVERSEFLOW.

4 In the drawing, select the pipe next to the number 2.

The flow direction for the branch is reversed, as indicated by the three flow arrows that are visible in the viewport.



In this exercise, you reversed the flow direction for a pipe segment and a branch. Because the pipe sizing tools used in the next chapter consider flow direction when determining the extent of a connected run, it is important to check the flow direction and make any necessary adjust-ments before sizing pipe runs.

NOTE Pipe sizing stops at a change in flow direction. When inserting a tee that splits the flow in a pipe run into opposite directions, you need to break the schematic pipes at the tee. Use the SFITTINGBREAKPIPE command, rather than the BREAK command to facilitate connecting the pipes.

Creating Construction Documents

When you have finished the initial layout of the plumb-

ing design, you move on to sizing the design. Previously

done by hand, or with a third party application, the

Plumbing module of Autodesk® Building Systems pro-

vides a tool to size the pipes. After the pipes have been

sized, you add labels and annotations, and you fill out

the schedules to complete the construction documents.

Autodesk Building Systems helps to automate the anno-

tation and scheduling tasks as well.

Lesson 7: Sizing a Plumbing System

Traditionally, in order to do pipe sizing for a system, you begin by calculating the length of the longest pipe run and the number of fixture units served by the pipe. In the Plumbing module of Autodesk Building Systems, this infor-mation is already contained in your drawing, stored in the objects them-selves. This lesson shows how to use that information to calculate pipe sizes.

NOTE Supply pipe sizing requires that you have defined a hot water or cold water system type for the system you want to size. In this tutorial, the system types for the supply systems are Domestic Cold Water and Domestic Hot Water.


■ Exercise 1: Sizing the Cold Water Supply System

■ Exercise 2: Sizing the Sanitary Waste System

Exercise 1: Sizing the Cold Water Supply System

When sizing supply pipe, you use the Size Schematic Pipe command and then select the pipe run to be sized. When you make this selection, the soft-ware highlights all of the pipes, fittings, and fixtures that will be considered in the pipe sizing calculation, and finds the flow rate, velocity, and diameter for the selected pipe.

In the Size Supply Pipe dialog box, you select the pipe sizing table you want to use and enter two values: the water pressure from the source, and the min-imum pressure required by the highest fixture in your supply pipe run. Based on this information, the software calculates the pipe size for the selected run, displays the values in the Size Supply Pipe dialog box, and applies the size information to the supply pipe in the selected pipe run.

NOTE Typically, when you draft a plumbing system, you draw the pipe runs in the direction of flow. Because proper flow direction is critical to pipe sizing in the Plumbing module, there are features that can help you draft your system with proper flow direction. First, you can draw in the opposite direction from the flow when you are adding a schematic pipe to an MvPart connector, and the cor-rect flow direction will be assigned to the pipe based on the information inherent in the connector. Second, if you draw in the opposite direction from the flow when connecting schematic pipe segments, you can use the Reverse Flow com-mand to change the flow direction assigned to the pipe segment. If the system you are sizing has been drawn in this manner and all of the pipes, fittings, and

Lesson 7: Sizing a Plumbing System | 93

fixtures are properly connected, the entire system will be considered when you size individual pipe runs. For example, when sizing the cold water supply system, you would select the pipe that comes in from the source, and the entire system would be considered when the source pipe was sized.


Size the source pipe

1 Select the schematic pipe next to the number 1, right-click, and click Size Schematic Pipe.

The software highlights all of the connected pipes, fittings, and fixtures for this pipe run. The software also finds the flow rate, velocity, and pipe diameter for the selected pipe.

2 In the Size Supply Pipe dialog box, specify the design values:

■ Select Tutorial Standard for Pipe Sizing Table.

When calculating the Developed Length of the pipe run, the software refers to the specified supply pipe sizing table to get equivalent pipe length values for all connected fittings and valves.

■ Verify that Pressure at Source is 413.6854 kPA.■ Verify that Pressure-Highest Fixture is 103.4214 kPA.

The results of the supply pipe sizing are displayed under Calculations for the Longest Run and Calculations at Selected Component.


3 Review the pipe sizing results in Calculations for the Longest Run.

This section displays the developed length, elevation difference, pressure drop, and downstream fixture units for the longest connected pipe run within your selection. These values are not editable. To calculate Devel-oped Length, the software adds the lengths of the pipe segments to the equivalent pipe lengths of all connected fittings and valves located on the same run. To calculate Downstream Fixture Units, the software reads and totals the required cold water supply fixture units for all connected fix-tures.

4 Review the pipe sizing results in Calculations at Selected Component.

This section displays the flow rate, velocity, and pipe diameter for the pipe you selected. These values are not editable. To find these values, the soft-ware reads the flow direction for the pipe, and then reads the values for the end of the pipe that is closest to the source.

5 Notice that the selected pipe run is sized at 50 mm.


Based on the information in your drawing, the values in the Tutorial Stan-dard supply pipe sizing table, and the information you entered for Pres-sure at Source and Pressure-Highest Fixture, the selected pipe is sized at 50 mm.

6 Click OK to close the Size Supply Pipe dialog box.

7 Verify that the calculated size has been added to the property information for the schematic pipe:

■ Select the pipe you just sized.■ Right-click, and click Schematic Pipe Modify.■ Notice that Nominal Size is 50 mm.

■ Click OK to close the Modify Schematic Pipes dialog box.

Size the main branch

8 In the drawing, select the cold water supply pipe next to the number 2, right-click, and click Size Schematic Pipe.

The software highlights all of the connected pipes, fittings, and fixtures for sizing this pipe run. The software also finds the flow rate, velocity, and pipe diameter for the selected pipe.



■ Verify that Tutorial Standard is selected for Pipe Sizing Table.■ Verify that Pressure at Source is 413.6854 kPA.■ Verify that Pressure-Highest Fixture is 103.4214 kPA.■ Review the pipe sizing results.

The values in the Calculations for the Longest Run and Calculations at Selected Component sections are the result of the pipe sizing and are not editable. Based on the information in your drawing, the values in the Tutorial Standard supply pipe sizing table, and the information you entered for Pressure at Source and Pressure-Highest Fixture, the selected pipe is sized at 50 mm.


Size the pipes for the toilets in the women’s bathroom

11 In the drawing, select the pipe segment connecting the women’s accessi-ble toilet to the supply branch, right-click, and click Size Schematic Pipe.

The software highlights the connected fixture for sizing this pipe run.



■ Verify that Pipe Sizing Table is Tutorial Standard.■ Verify that Pressure at Source is 413.6854 kPA.■ Verify that Pressure-Highest Fixture is 103.4214 kPA.■ Notice that the selected pipe is sized at 32 mm.


14 Repeat this process for the next two toilets in the women’s bathroom, and then click OK.


The pipes for these toilets are sized at 32 mm.

15 Repeat this process to size the pipe run connecting the last (top) toilet, by selecting the pipe near the number 3.

The software highlights all of the connected pipes, fittings, and fixtures on this branch, calculates a downstream fixture unit load of 24, and sizes the pipe at 32 mm.

16 Click OK.

The pipe sizing for the women’s bathroom is complete. The pipes for the lavatories can remain at the size that was established by the connectors


when the schematic pipes were added. The current pipe size is more than adequate for the fixture units associated with the lavatories. The pipe siz-ing tool considers the lavatories’ fixture units when sizing the pipe run to which they are connected; however, it does not size the pipes for the lav-atories because they are downstream of the transition fitting on the pipe run.

Insert fittings

Because the main supply branch is sized at 50 mm and the branch to the women’s bathroom is sized at 32 mm, you need to insert a transition fit-ting in the branch. You also need to insert an isolation valve on the same branch to facilitate maintenance of the women’s room.


18 Select Plumbing Fittings UK for Fittings, and select Concentric Transition.

19 If you have not already enabled the pushpin feature, click the pushpin in the upper right corner of the Add Schematic Pipe Fittings dialog box.

20 In the drawing, select the branch to the women’s bathroom next to the number 3, move the cursor up, and click to set the rotation of the fitting, as shown.


The concentric transition is inserted into the branch and the Add Schematic Pipe Fittings dialog box remains open.

21 In the Add Schematic Pipe Fittings dialog box, select Plumbing Gate Valves UK for Fittings.

22 Click the Lever category bar, and select Gate Valve Lever.

23 In the drawing, select a point above the concentric transition, move the cursor up, and click to set the rotation of the fitting, as shown.

The valve is inserted into the branch.

24 In the Add Schematic Pipe Fittings dialog box, click Close.

Size the pipes for the fixtures in the men’s bathroom

25 In the drawing, select a point next to the number 4 on the pipe run sup-plying the men’s bathroom, right-click, and click Size Schematic Pipe.


The software highlights all of the connected pipes, fittings, and fixtures on this branch, and sizes the pipe at 32 mm. The pipes for basins are not sized because they are downstream of a reducer. The current pipe size is more than adequate for the fixture units associated with the basins, so the pipes can remain at the size that was established by the supply connectors when the schematic pipe was added.

26 Click OK.

27 Repeat the pipe sizing procedure to size the cold water supply pipe for each of the toilets in the men’s bathroom.

The pipes are sized at 32 mm.

28 Size the pipes for the urinals:

■ In the drawing, select the cold water supply pipe for one of the urinals.


■ Right-click, and click Size Schematic Pipe.■ In the Unable to Size Pipe dialog box, select 15 mm for the nominal

pipe size, and click OK.

The Unable to Size dialog box displays when the fixture unit load for the selected pipe run is below 5.

■ Repeat this process to size the cold water supply pipe for the second uri-nal.

Add fittings for the branch supplying the men’s bathroom


30 Select Plumbing Fittings UK for Fittings, and select Concentric Transition.


31 In the drawing, select the branch to the men’s bathroom next to number 4, move the cursor up, and click to set the rotation of the fitting, as shown.

The concentric transition is inserted into the branch, and the Add Schematic Pipe Fittings dialog box remains open.

32 In the Add Schematic Pipe Fittings dialog box, select Plumbing Gate Valves UK for Fittings.

33 Click the Lever category bar, and select the Gate Valve Lever.

34 In the drawing, select a point above the concentric transition, move the cursor up, and click to set the rotation of the fitting, as shown.

The valve is inserted into the branch.

35 In the Add Schematic Pipe Fittings dialog box, click Close.

Lock the size of the pipes for the urinals

Now that you have manually sized the pipe for the urinals, use the Modify Schematic Pipes dialog box to lock the nominal size of the pipe. Locking a pipe size prevents the pipe sizing command from resizing the pipe if you perform additional pipe sizing for the cold water supply system.

36 In the drawing, select the cold water supply pipe for one of the urinals.

37 Right-click, and click Schematic Pipe Modify.

38 In the Modify Schematic Pipes dialog box, click the lock to the right of Nominal Size.

The lock changes to a locked position to indicate that the current pipe size cannot be modified by the pipe sizing command.


The pipe size is locked.

39 Click OK to close the Modify Schematic Pipes dialog box.

40 Repeat this process to lock the pipe size for the second urinal.

NOTE There are three commands that you can use to view objects for sup-ply pipe sizing. Use the SHOWOBJECTSFORSIZING command to show all plumbing objects that will be considered when you size a pipe run. Use the SHOWPIPESTOSIZE command to show the schematic pipes that will be resized based on the pipe you select. Use the SHOWOBJECTSINLIMITINGRUN command to show the plumbing objects that have been calculated as the limiting pipe run.


In this exercise, you sized the main cold water supply pipes, the branches for the women’s and men’s bathrooms, and individual pipes as needed. You inserted transition fittings to accommodate reductions in pipe size, and isolation fittings to facilitate maintenance. When sizing the pipes for the urinals, you selected an appropriate pipe size, and then locked the size of the pipes to prevent further resizing. Next, you size the sanitary waste system.

Exercise 2: Sizing the Sanitary Waste System

Before you begin sizing sanitary pipe, you should have a complete draft of the sanitary pipe system. If you modify the system after you have sized it, you will need to size it again.

When you size a pipe run, you specify the type of run being sized: Branch, Offset (or home drain), Stack spanning three stories or less, or Stack spanning more than three stories. The type of run you select determines which tab of the sanitary pipe sizing table is referenced. For example, if you specify that the run you are sizing is a branch, the software refers to the values on the Branches tab of the sanitary pipe sizing table that you have selected for use.


In this exercise, you use the Tutorial Standard sanitary pipe sizing table, which you created in an earlier exercise.

NOTE Sanitary pipe sizing usually refers to sanitary black water systems types. If you create sanitary system types for gray water, you must define the system type as Waste in order for the sanitary pipe sizing to work. In the sample project, the floor drains are part of the Sanitary Black Water system.


Size the pipes for the floor drains

1 In the drawing, select the sanitary pipe connected to the floor drain on the left, right-click, and click Size Schematic Pipe.

The software highlights the connected floor drain for sizing this pipe run.

2 Review the settings in the Size Sanitary Pipe dialog box:

■ Select Tutorial Standard for Pipe Sizing Table.

This table is referenced to determine the maximum permissible fixture unit loads for different types of pipe runs. The fixture unit load is crit-ical in determining the pipe size requirements for your design.

■ Verify that Base Sizing On is Branch.

This selection controls which tab of the pipe sizing table is referenced. In this case, the Branches tab will be used for the sizing calculations.

■ Review the pipe sizing results.


The Fixture Units Upstream value displays the total number of fixture units for the fixtures connected to the selected pipe run. The Fixture Units Upstream value assumes that all connected fixtures are in the drawing that you are working on. After the Fixture Units Upstream Value has been determined, the Size of Branch Value is displayed. In this case, the branch is sized at 50 mm.

3 Click OK to close the Size Sanitary Pipe dialog box.

4 Repeat the pipe sizing procedure to size the pipe for the other floor drain.

The pipe is sized at 50 mm.

5 In the Size Sanitary Pipe dialog box, click OK.

Size the remaining sanitary waste pipes


7 Select Water Closet, click Set Current, and then click OK.

8 In the drawing, select the waste pipe near the number 1, right-click, and click Size Schematic Pipe.

The software highlights the connected fixtures for sizing this pipe run. In this case, both the drinking fountain and the floor drain are highlighted.


9 Verify settings in the Size Sanitary Pipe dialog box:

■ Verify that Pipe Sizing Table is Tutorial Standard.■ Verify that Base Sizing On is Branch.■ Notice that the fixture unit load has been calculated and that the pipe

run is sized at 50 mm.

■ Click OK to close the Size Sanitary Pipe dialog box.

10 Repeat the pipe sizing procedure to size the pipe run on which the toilets are connected.


The pipe is sized at 100 mm.

11 Click OK.

12 Press ENTER to repeat the Size Schematic Pipe command.

13 Select the horizontal pipe run at the top of the drawing, which is the pipe that connects to the building exit.

14 Specify pipe settings in the Size Sanitary Pipe dialog box:

■ Verify that Pipe Sizing Table is Tutorial Standard.■ Select Offset/Home Drains for Base Sizing On.■ Notice that the fixture unit load has been calculated and that the pipe

run is sized at 100.


■ Enter 150 for Fixture Units from Branches Connecting Outside of this Drawing.

When you press ENTER, the Size of Pipe value is recalculated. With the increased fixture unit load, the pipe is sized at 125.


You have sized the sanitary waste system for one floor of the building in this sample project. To perform sanitary pipe sizing for a multiple-story building, save each floor of the building as a separate drawing, and then size each floor individually. Begin sizing at the highest level that has a fix-ture unit load (the roof or the top floor), and proceed downward to the lowest floor. Record each floor’s fixture unit load for your reference, because you need to enter the accumulated fixture units for the upper floor(s) in the Size Sanitary Pipe dialog box for each lower floor you size. Finally, you need to size the stack. One method for sizing a stack is pre-sented in the next procedure.

Size the stack


16 Select Stack, click Set Current, and click OK.

17 In the drawing, select the small horizontal pipe that is marked STACK FROM ROOF, right-click, and click Size Schematic Pipe.

This short pipe segment is connected to a pipe that runs from the tee up 12 meters, allowing you to size the stack for the multi-story building in this sample project. Typically, after you size the stack, you would delete this pipe segment from your drawing.


18 Specify pipe settings in the Size Sanitary Pipe dialog box:

■ Verify that Pipe Sizing Table is Tutorial Standard.■ Select Stacks Spanning More than Three Stories for Base Sizing On.■ Review the pipe sizing results.

The Fixture Units from Branches Connecting in this Drawing is 47, and the stack is sized at 80 mm. Now you need to add the accumulated fix-ture unit load from the top three floors of the building in this sample project. The total is 150.

■ Enter 150 for Fixture Units from Branches Connecting Outside of this Drawing.

When you press ENTER, the Size of Stack value is recalculated. With the increased fixture unit load, the stack is sized at 100 mm.



NOTE There are two commands that you can use to view objects for sani-tary pipe sizing. Use the SHOWOBJECTSFORSIZING command to show all plumbing objects that will be considered when you size a pipe run. Use the SHOWPIPESTOSIZE command to show the schematic pipes that will be resized based on the pipe you select.


In this exercise, you sized the sanitary waste system for the first floor of the building in the sample project. You also sized the stack for the build-ing, based on a supplied value for the accumulated fixture units for the upper floors. As part of sizing your plumbing systems, add transition fit-tings where they are required. Also, it is recommended that you have an engineer review your design and adjust it as needed. Next, you label your design.


Lesson 8: Labeling a Plumbing System

To complete the documentation phase of a project, annotation is added to the design and schedules are created. This lesson shows how to use size labels, flow arrows, and leader tags to annotate your drawing. In the next les-son, you add schedule tags and create a schedule table as the final step in pre-paring construction documents.

Autodesk Building Systems provides two types of annotation: labels and doc-umentation symbols. When you want to display object information, such as text, blocks, and dimensions in your drawing, use labels. When you want to add information like title marks and leader tags, use annotation symbols from DesignCenter. This lesson shows how to use both types of annotation.

Labels are Building Systems objects. They can inherit object properties from attached objects, such as fixtures or pipes, and display them as text. For example, a label can read the size or the system abbreviation of a pipe to which it is anchored, and display the dimension or system abbreviation as text in your drawing. Labels can also display blocks, such as flow arrows, which inherit their orientation from the pipes to which they are anchored. If the anchored object is modified, the label is updated dynamically. For example, if the size of the pipe is modified, the label attached to it reflects the change in size.

When you add a label to an object, you specify the label style. The label style determines the text style, the position of the text on the object, the informa-tion displayed in the label, and how the label is displayed in your drawing. When a label is placed in a drawing, it reads the drawing scale and annota-tion plot size from the Drawing Setup settings, and the size of the label text is based on these settings. The flow arrows and size labels you add to your drawing in this lesson use label styles supplied with Autodesk Building Sys-tems.


■ Exercise 1: Adding Flow Arrow Labels

■ Exercise 2: Adding Size and System Labels

■ Exercise 3: Annotating Your Drawing

Exercise 1: Adding Flow Arrow Labels

One type of labeling that is generally included on construction documents is flow arrows. Flow arrows indicate the direction in which materials flow through the systems in your design. In this exercise, you add flow arrow

Lesson 8: Labeling a Plumbing System | 113

labels to the cold water supply system. The flow arrow label reads the flow

direction from the pipe to which it is anchored, and displays an AutoCAD® arrow block that indicates the direction of flow.


Add flow arrow labels to the cold water system

1 On the status bar, verify that Osnap is turned off.

2 Open the Annotation and Utilities tool palette and click the Add Label tool.

3 In the drawing, select the cold water supply pipe next to the number 1.

4 In the Add Labels dialog box, select Flow Arrow Label - Closed Filled for Label Style.

5 Select One by one for Layout Method.


6 Press ENTER.

7 Apply the label to the cold water supply pipe next to the number 1, as shown.

The flow arrow label is inserted on the schematic pipe, with the arrow oriented to show the direction of flow.

8 Select the cold water supply pipe next to the number 2 as the next object to label.

9 Press ENTER to accept the default values in the Add Labels dialog box, and select a point next to the number 2 to insert a second flow arrow on the same pipe.

The second flow arrow label is inserted on the schematic pipe, with the arrow oriented to show the direction of flow.

The flow direction is different on this side of the tee because the pipe sup-plies the bathroom facilities.



In this exercise, you added flow arrows to show flow direction for the cold water supply system. Next, you continue annotating your drawing by add-


ing labels that display pipe size and system abbreviation for the cold water supply system.

Exercise 2: Adding Size and System Labels

Pipes are often labeled with size and system. Autodesk Building Systems pro-vides label styles that read the size and system abbreviation of schematic pipes, and display these values as text in your drawing. Standard labels dis-play the pipe’s size. System labels display the pipe’s system abbreviation from its system definition. This exercise shows how to use both Standard and Sys-tem label styles.


Label pipes using the Standard label style


2 In the drawing, select the cold water supply pipe next to the number 1.

3 In the Add Labels dialog box, select Standard for Label Style.

4 Select One by one for Layout Method, and press ENTER.

5 Apply the label to the cold water supply pipe next to the number 1, as shown.

The Standard label style is applied to the pipe. It reads the pipe’s 25 mm size and displays it as label text.

6 In the drawing, select the cold water supply pipe below the number 2.

7 Press ENTER to accept the label style and layout method.


8 Click to apply the label to the cold water supply pipe below the number 2, as shown.

The label is applied to the pipe and displays its size as 40.

9 Using the same procedure, apply a Standard label to the pipe labeled Source in the drawing, as shown.

The label is applied to the cold water source pipe and its size is displayed as 50.


Offset a label

11 Select the last label you added, right-click, and click Offset Node.

12 Press ENTER to accept the default to not edit one node at a time.

NOTE By accepting the default setting when multiple objects are selected, all of the labels associated with those objects are offset.

13 Move the cursor to the right and click to select a new insertion point for the label, as shown.


The label is repositioned using the Offset Node command.

Label pipes using the System label style

14 On the Annotation and Utilities tool palette, click the Add Label tool.

15 In the drawing, select the main cold water supply branch, which is the horizontal blue line at the bottom of the drawing.

16 In the Add Labels dialog box, select System Label for Label Style.


18 Apply the label to the main cold water supply branch to place the label, as shown.


The label is applied to the pipe and displays its system abbreviation as CW for Cold Water.

19 Apply a System label to the main hot water supply branch, as shown.

The label is applied to the pipe and displays its system abbreviation as HW for Hot Water.

NOTE The size of the label text in your drawing is based on two drawing setup values: Drawing Scale and Annotation Plot Size. The labels’ size is linked to these two values dynamically; therefore, changing either value changes the size of the text displayed by these labels. These setup values determine text size only when no text height is defined in the label style. If you want the size of the label text to be a fixed height, you can create a text style that has a fixed height, and then apply it to the label style you want to use.



In this exercise, you used the Standard label style to add size labels to the cold water supply pipes. You used the Offset Node command to reposition labels as needed. You also used the System label style to label the main cold water and hot water supply branches with their system abbreviations. Next, you add annotations from DesignCenter to your drawing.

Exercise 3: Annotating Your Drawing

This exercise shows how to add documentation symbols, such as leader tags and title marks, to your drawing. Documentation symbols are accessed through tool palettes and DesignCenter. They can be accessed and inserted into your drawing using the documentation content commands in Autodesk


Building Systems. When you insert documentation symbols from tool pal-ettes or DesignCenter, follow the prompts to provide input for annotation variables such as text, location, angle, and number of symbols to add.

Like labels, the scaling of symbols is controlled by the Drawing Scale and Annotation Plot Size settings. However, unlike labels, the scaling of annota-tion symbols is not dynamic. After an annotation symbol is placed in a draw-ing, its size is fixed. Annotation symbols that display text, such as title marks, elevation marks, and section marks, use the current text style to create their text.

Like the schematic pipes in your drawing, annotation symbols are layer keyed. A layer key is a map between a defined layer and a Building Systems object that you add to your drawing. Using layer keys to place objects on lay-ers is called layer keying. Layer keying enforces the use of layer standards. The layer standard used in Autodesk Building Systems is a modified version of the AIA layer standard. Under this standard, a layer name is made up of four fields: Discipline, Major, Minor, and Status. For example, according to the Plumbing layer standard, the layer for a domestic water pipe is P-Domw-Pipe. A layer key override is used to modify, or override, part of the layer name.

The layer keying for annotation symbols in DesignCenter places them on layers that are set up with a Discipline of A to denote Architectural annota-tion. In this exercise, you use a layer key override to place all annotation on layers with a Discipline of P to denote them as Plumbing layers.

NOTE When a layer key override is in effect, it applies to all objects added to the drawing.


Set the layer key Discipline to Plumbing

1 On the Format menu, click Layer Management ➤ Layer Key Overrides.

2 Click the [...] button to the right of Discipline Designator.


3 Select P, “Plumbing”, and click OK.

4 Click OK.

Add a leader line and text to a shutoff valve

5 Zoom in to the water heater on the left side of your drawing.

6 On the status bar, verify that Polar, Osnap, and Otrack are turned off.

7 Open the Architectural tool palette, click the Architectural Annotation tab, and then click the Text (Straight Leader) tool.

8 Specify a point above and to the right of the shutoff valve on the vertical 25 mm cold water line for the leader start point.

9 Move the cursor up and to the right and specify the second leader point.


10 Move the cursor to the right and specify the leader endpoint.

11 Press ENTER to complete the leader.

12 On the command line, enter 25 mm SHUT, press ENTER to move to a new text line, and enter OFF VALVE.

13 Press ENTER twice to end the command.

The leader line and text are added to the drawing on layer P-Anno-Note.

14 Zoom in to the men’s bathroom.

15 On the Annotation and Utilities tool palette, click the Text (Straight Leader) tool.

16 Select a point near the floor drain in the men’s bathroom, move the cursor a short distance up and to the left and click.

17 Move the cursor a short distance to the left and click.

18 Press ENTER to end the line.

19 On the command line, enter PROVIDE TRAP SEAL, press ENTER to move to a new text line, and enter PRIMER FOR FLOOR DRAINS.


The second leader line and text are added to the drawing on layer P-Anno-Note.

Add a title mark

21 Open the Callouts tool palette and select the TitleMark tool.


22 Specify a point in the lower-left corner of the drawing to locate the title mark.

23 Move the cursor to the right and specify the endpoint of the title mark line.

The title mark is placed in your drawing with generic number, title, and scale attributes.

24 Select the VIEWNUMBER text, right-click, and then click Edit Attributes.

25 In the Enhanced Attribute Editor dialog box, enter 1 for Value.

26 Click OK.

27 Select the VIEWTITLE text, right-click, and then click Edit Attributes.

28 In the Enhanced Attribute Editor dialog box, do the following:


■ Under Tag, select SCALE and enter 1 = 100 mm for Value.■ Under Tag, select TITLE and enter Partial 1st Floor Plumbing Plan for

Value.

29 Click OK.

Remove the layer key override


31 In the Override column, double-click P and then press BACKSPACE to delete this override.

32 Click OK to close the Layer Key Overrides dialog box.


In this exercise, you finished annotating your drawing by adding docu-mentation symbols. You used a layer key override to place all of the anno-tation on layers with a Discipline of P to denote them as Plumbing layers. When you finished placing annotation symbols, you removed the layer


key override as a matter of good practice. Next, you add schedule tags to the fixtures in your drawing in preparation for generating a schedule table.

Lesson 9: Scheduling a Plumbing System

Collecting project data from your layout to create accurate schedules is an important part of building design. Traditionally, scheduling has been one of the most complex and time-consuming tasks in creating construction docu-ments. In Autodesk Building Systems, schedule tables that you create are linked to Building Systems objects and styles in your drawings, allowing them to be updated dynamically whenever you make changes to your design. Schedule tables can be linked to objects, such as MvParts, using schedule tags. Some property set data is attached to the MvParts when you add schedule tags to the parts. The software prompts you to enter additional values that are stored with the part as property set data. Any property included in the property set data can be displayed in a schedule table.

In this lesson, you attach schedule tags to the MvParts you are scheduling. Schedule tags link the property set data (the actual object property values) to the objects being scheduled. You also add a schedule table to your drawing using a schedule table style. Schedule table styles control the overall format and appearance of the schedule table, such as column structure and display properties. Finally, you edit the schedule table to suit your needs.


■ Exercise 1: Adding Schedule Tags to Fixtures

■ Exercise 2: Importing a Schedule Table Style

■ Exercise 3: Generating a Schedule Table

■ Exercise 4: Modifying a Schedule Table

Exercise 1: Adding Schedule Tags to Fixtures

This exercise shows how to attach schedule tags to plumbing fixtures (MvParts). The values you enter become part of the property set data for the MvPart. Some values are displayed on the tag itself; some values display in the schedule table you add to your drawing. Property set data is attached to the MvPart. No data is stored in the schedule tag or in the schedule table; the tag and the table objects merely display the property set data associated with the MvPart.

Lesson 9: Scheduling a Plumbing System | 125


Add schedule tags to fixtures

1 Open the Plumbing tool palette and click the Fixture Tag tool.

2 Select the accessible toilet in the men’s bathroom as the fixture to tag.

3 Select a point to the upper left of the toilet as the location for the tag.

When you place the tag in the drawing, the Edit Property Set Data dialog box displays.

4 Enter W-2 for Item.

5 Enter KOHLER for Manufacturer and click OK.


The command is still active, so you can continue tagging fixtures.

6 Use the same Item and Manufacturer values to add a tag to the accessible toilet in the women’s bathroom, as shown.

The fixture tags are attached to the accessible toilets in both of the bathrooms.

Attach schedule tags to a group of fixtures

The command is still active, so you can continue tagging fixtures.

7 Select any untagged toilet, and click below the toilet to place the tag.

8 In the Edit Property Set Data dialog box, click OK without making any changes.


9 Tag each of the remaining toilets in both the women’s and men’s bath-rooms by selecting each fixture, positioning the tag, and clicking OK with-out changing any of the property set data.

Fixture tags are added for all of the toilets in the drawing.


11 Select the four toilets with no defined tag, right-click, and click MvPart Properties.

12 On the General tab, click Property Sets.

13 Specify the property set data:

■ Enter WALL HUNG-FLUSH VALVE for Description.■ Enter W-1 for Item.■ Enter KOHLER for Manufacturer.■ Enter K-4330 for Model.■ Enter SLOAN ROYAL #111-YO for Model Number.■ Click OK twice.


The tags for the selected toilets are updated accordingly.

All of the toilets in the drawing have schedule tags, which means that they have some property set data attached. The Item value displays on the tag itself; the additional values you entered can be displayed in the schedule table.


Schedule tags behave differently from the labels you worked with in a pre-vious lesson. Unlike labels, schedule tags are not anchored to objects, but are attached only through linked information. Because the tags are not anchored to the diffusers, you can move them once they are placed in the drawing.

Another difference between schedule tags and labels is the way they are scaled. Unlike labels, schedule tags are not dynamically updated when you change the scaling variables for your drawing. Schedule tags refer to the Drawing Scale and Annotation Plot Size values only when they are inserted into the drawing.

NOTE Schedule tags are designed to use the current text style when placed in a drawing; therefore, it is beneficial to set the desired text style as the cur-rent text style before you begin placing tags.


In this exercise, you attached schedule tags to the objects to be included in the schedule table. Next, you import schedule table styles into your drawing in preparation for generating a schedule table.

Exercise 2: Importing a Schedule Table Style

In order to add a schedule table to your drawing, the drawing must contain schedule table styles, which determine the appearance and the categories of data in the schedule table. Autodesk Building Systems provides sample schedule table styles stored in separate drawings that you import into your current drawing. These styles are predefined according to common industry standards. You can modify the styles or create new ones.

This exercise shows how to use Style Manager to import a schedule table style for scheduling the plumbing fixtures in your drawing. It also shows how to purge unused schedule table styles.


Import a style from another drawing using drag and drop functionality

1 On the Format menu, click Style Manager.

2 In Style Manger, on the File menu, click Open Drawing.

3 In the left pane, click Content, and browse to Styles\Metric.

4 Click ABP Schedule Tables (Metric) 3 UK.dwg, and click Open.

5 In the left pane of Style Manager, under ABP Schedule Tables (Metric) 3 UK.dwg, expand Documentation Objects, and double-click Schedule Table Styles.


The right pane of Style Manager displays all the sample schedule table styles in the selected drawing. You can drag styles from the right pane into your current drawing in the left pane.

6 In the right pane, hold down CTRL and select Fixture Schedule, Fixture Unit Schedule, and Hazard Tank Schedule.


7 Drag the selected styles from the right pane into the current drawing (m_abp5_L09_E2.dwg) in the left pane.

8 In the left pane, expand Documentation Objects and Schedule Table Styles for the current drawing to view the styles you copied.


The selected styles now exist in the current drawing.

Preview and copy a style into your drawing using right-click functionality

9 In the left pane, expand Schedule Table Styles for ABP Schedule Tables (Met-ric) 3 UK.dwg, and select Pump Schedule.

10 In the left pane, right-click Pump Schedule, and click Copy.

11 Select the current drawing (m_abp5_L09_E2.dwg), right-click, and click Paste.

12 Expand Schedule Table Styles for the current drawing to view the style you copied.


The Pump Schedule style is copied into the current drawing.

Purge unused styles from the drawing

You can purge styles from drawings using the right-click menu, or using the trash can icon in Style Manager.

13 In the left pane, right-click Schedule Table Styles for the current drawing (m_abp5_L09_E2.dwg), and click Purge.

14 Clear Fixture Schedule and Fixture Unit Schedule to keep them in the drawing, and click OK.


The selected styles are purged from the current drawing. You can purge only those styles that are not used in the drawing. When you run the Purge command on schedule table styles, it purges the unused instances of the selected styles. You can also remove styles one at a time by selecting individual styles and purging them. When you run the Purge command on a drawing, it purges all styles in the drawing.



In this exercise, you imported a schedule table style for scheduling the plumbing fixtures in your drawing (Fixture Schedule). Schedule table styles define the visual characteristics of the schedule table, including the text configuration and the layout of columns and headers. Predefined schedule table styles are stored in drawings and can be imported into your current drawing using Style Manager. Your drawing must contain sched-ule table styles before you can add a schedule table. Next, you use the Fix-ture Schedule table style to add a schedule table to your drawing.

Exercise 3: Generating a Schedule Table

Schedule tables are display objects that hold no data on their own. They extract and display property set data that is attached to objects in your draw-ing. Each column of the Fixture Schedule lists one property associated with an MvPart. The schedule table style that you select determines the columns that are included in the schedule table. For example, the Fixture Schedule has columns for Item, Quantity, Manufacturer, Model, and several other proper-ties for which you can specify property set data.

Two types of property set data can be associated with objects: object data and style data. Object data must be attached to any object you want to schedule. Style data is required only if the schedule table style calls for information stored in the objects’ style. The schedule table style used in this exercise, Fix-ture Schedule, does not require style data. It uses only object property set data, which you defined when you applied schedule tags to the toilets in your drawing.

NOTE Regardless of the type of property set data you add, or the method you use to associate it with an object or its style, the linking happens through an unseen intermediary, the property set definition. Property set definitions are groups of object properties dynamically linked to the schedule tables. Property set definitions can be either style based or object based. Style-based definitions


apply to all objects of a specific style, while object-based definitions apply to indi-vidual objects.

This exercise shows how to select the parts to be scheduled and how to gen-erate a schedule table for your drawing. In the dataset for this exercise, sched-ule tags have been applied to all of the plumbing fixtures, and the required property set definitions have been added.


Generate a schedule table

1 Open the Plumbing Equipment tool palette and click the Fixture Schedule tool.

2 On the command line enter all to select all objects in the drawing, and press ENTER.

3 Press ENTER to end your selection.

4 Select a point below the curtain wall at which to place the upper-left cor-ner of the schedule table.

5 Press ENTER to accept automatic sizing of the table based on the drawing scale.


The schedule table is added to your drawing.

6 In the drawing, zoom in to see the detail displayed in the schedule table.

The schedule table contains double hyphens (--) wherever object property set data has not been defined for fixtures. You can add this missing data by editing the cells in the Fixture Schedule in your drawing, as shown in the next exercise.


In this exercise, you used a predefined schedule table style to generate a schedule table in your drawing. Next, you modify the schedule table’s content and appearance.

Exercise 4: Modifying a Schedule Table

After you add a schedule table to your drawing, you will probably need to modify the data in the schedule as your design evolves. This exercise shows two methods for modifying the schedule table’s content: editing the property


set definitions associated with the scheduled MvParts, and editing cells in the table itself, which changes the objects’ property set definitions. This exercise also shows how to modify the table’s appearance by deleting and moving col-umns. In order to make the table easier to work with, you begin by deleting and moving columns.


Delete columns from the schedule table

1 Select the schedule table in your drawing, right-click, and click Edit Sched-ule Table Style.

2 Click the Columns tab, and scroll to the right until the Supply Fitting col-umn is visible.

3 Select the Supply Fitting column header, click Delete, and click OK.


4 Repeat this procedure to delete the Supply Pipes, Drain, and Trap columns from the table.

5 Click OK to close the Schedule Table Style Properties dialog box.

The Supply Fitting, Supply Pipes, Drain, and Trap columns are removed from the schedule table.

Rearrange the order of the columns in the schedule table

6 Select the schedule table in your drawing, right-click, and click Edit Sched-ule Table Style.

7 On the Columns tab, select the Quantity column header.

8 Drag the header to the left until it is positioned over the Item column, and release the mouse button to drop the column in place, as shown.


You can move any column using this method.

9 Click OK to close the Schedule Table Style Properties dialog box.

The Quantity column is now the first column in the schedule table.

Edit table cells to change object properties

When you edit the values in the schedule table, you are editing the values in the objects’ property set definitions. Schedule tables do not hold prop-erty information, they merely display the property information attached to the objects you have selected.

10 Select the schedule table in your drawing, right-click, and click Edit Table Cell.

11 In the Description column, click the double hyphen (--) in the row for W-2.

12 Enter WALL HUNG-FLUSH VALVE for Description.

13 In the Model column, click the double hyphen (--).


14 Enter K-4330 for Model, and click OK.


The schedule table is updated with the values you entered. The object’s property set definition is updated as well.

Edit a property set definition to modify the table

16 On the Navigation toolbar, click on the Zoom flyout.

17 Use a window to select the area around the rest rooms, as shown.


You zoom in to make selecting objects easier.

18 In the drawing, select the two accessible toilets, right-click, and click Prop-erties.

19 In the Properties palette, click the Extended Data tab.

20 Expand Property Sets, and expand MvParts-FixturesObjects, if necessary.

21 Enter BENEKE #523 SEAT ADA for Accessories.

22 Enter MOUNTED 450 mm for Remarks.

23 Enter SLOAN ROYAL #111-YO for Trim.

24 Verify that Vent is 0.

25 Verify that Waste is 2.

26 Verify that DCW is 6CWFU.

27 Verify that DHW is 0HWFU.



29 Select the schedule table, right-click, and click Update Schedule Table.

30 Click on the Zoom flyout menu to see the updated schedule table.


The row for item W-2 of the schedule table is updated with the values you entered in the MvPart’s property set definition.


In this exercise, you modified the schedule table’s content in two ways: by editing the cells in the table itself, and by editing the property set defini-tions associated with the MvParts. You also modified the table’s appear-ance by deleting and moving columns. Next, you create a schematic riser diagram for the sanitary waste and vent systems in your design.

Working with Schematic Diagrams

Schematic drawings are 2D, not-to-scale diagrams that

show the organization and operation of a system. They

can take the form of orthographic diagrams, such as a

building condenser water flow diagram, or isometric

diagrams that depict, in 2D, the entire building water or

waste and vent system. Autodesk® Building Systems

contains tools for creating schematic drawings, includ-

ing libraries of schematic symbols with connectors. As

you draft, you can connect these symbols with sche-

matic lines that recognize the connectors and snap to

them. The software also includes styles for schematic

symbols and lines that control their appearance and

behavior.

In this chapter, you work with schematic lines and sym-

bols as you create, modify, and annotate a schematic

drawing.

Lesson 10: Adding Schematic Lines and Symbols

This lesson shows how to connect schematic lines and symbols to create a schematic diagram that shows the basic function of the sanitary waste sys-tem included in your overall plumbing design. Schematic lines behave in some ways like schematic pipe. Both objects have a system and a style. Like schematic pipe, the system definition for schematic lines determines the sys-tem label and the layer, while the style controls how crossing lines will be dis-played and how the lines will be trimmed. Unlike schematic pipe, schematic lines do not use elevations, nor do they have a 3D representation. Schematic lines and schematic symbols have their own set of Building Systems snaps, along with their own types of anchors and relationships to each other.

Typically, as you create a schematic diagram, you alternate between drawing schematic symbols and lines. How you place schematic symbols and lines rel-ative to each other determines whether a symbol is an end-of-line schematic symbol or an in-line schematic symbol.

■ End-of-line symbols are placed first, with schematic lines added to them. The line is anchored to the symbol. Because of this relationship, you can think of end-of-line symbols as symbol-anchored lines. A typical example of an end-of-line symbol is a pump.

■ In-line symbols are added to schematic lines. The symbol is anchored to the line. Because of this relationship, in-line symbols are line-anchored symbols. A typical example of an in-line symbol is a valve.

Two Building Systems snaps help you work with schematic symbols and lines. The Schematic Connector snap selects connectors on schematic sym-bols and endpoints of schematic lines. The Schematic Curve snap selects a point on a schematic line.

In this lesson, you add schematic lines and apply schematic line styles and system definitions to them. You then add in-line schematic symbols that rep-resent the laterals and fixtures.

Exercise 1: Starting a Schematic Drawing

This exercise shows how to add schematic lines to a drawing to begin your schematic diagram.

NOTE The riser diagram used in this lesson is based on a preliminary design, and differs slightly from the final design used in the previous chapters of the tutorial.


Add a waste line

1 Establish the settings for your drawing variables:

■ On the status bar, verify that Ortho, Polar, and Osnap are turned off.■ On the MEP Common menu, click Compass ➤ Compass Settings. Ver-

ify that both Enable snap and Enable tick marks are selected, and that they are set to 15 degrees.

■ Change the color of the Compass if you want, and then click OK.

2 Open the Plumbing Isometrics and Schematics tool palette and click the Add Schematic Line tool.

3 In the Add Schematic Lines dialog box, specify the settings for the line:

■ Select Standard for System.■ Select Standard for Style.■ Select Isometric, Isoplane Right for Mode.■ Enter 100 for Designation ID.

Schematic lines do not have widths. By specifying a width in the Designa-tion ID field, you can label the line with width information. Building Sys-tems labels can read the Designation IDs of schematic lines, and display the IDs as text in your drawing.


4 Click the pushpin in the upper right corner of the Add Schematic Lines dialog box to minimize the dialog box to its title bar.

When you move the cursor off the dialog box, you get an unobstructed view of the drawing area, making it easier to place objects.

After clicking the pushpin, you can work in the drawing area without clicking in the area first. The dialog box redisplays when you move the cursor over the title bar.

5 In the drawing, select a point near the number 1 and draw a line to the number 2.

When you draw a schematic line in Isometric mode, the line is restricted to the specified Isometric plane, in this case Isometric Right.

6 Click Close in the Add Schematic Lines dialog box to end the command.

7 Select the line to see that it is placed on layer P-Detl.


The schematic line is placed on layer P-Detl by default. You can override the default layer assignment by defining a schematic system for the line.

Add a line in Isometric mode

8 With the line still selected, right-click, and click Add Selected.

The values are read from the schematic line and displayed in the Add Schematic Lines dialog box.

9 Enter 50 for ID.

10 In the drawing, draw a schematic line from the number 3 to the number 4.


When connecting to an existing schematic line, you may find it helpful to draw past the connection point and then trim the line. Otherwise, the line may break out of the isometric restraints if they are overridden by the schematic connector snaps.

11 In the Add Schematic Lines dialog box, click Ortho to activate Ortho-graphic mode.

You can move between Isometric and Orthographic modes as you draw. In Orthographic mode, you can draw outside the constraints of the Iso-metric plane in which you have been drawing. You also have the Compass to guide your drafting.

12 Draw a schematic line to the number 5, using the Compass to angle the line at 75 degrees. Use the schematic curve connector to snap to the line.

13 In the Add Schematic Lines dialog box, click New Run.

14 Click Isometric to activate Isometric mode, and then click Right to change planes.

15 Select Sanitary Black Water for System.

16 Verify that ID is 50.

17 Add a schematic line from the number 6 to the number 7 in the drawing.


18 In the Add Schematic Lines dialog box, click New Run, and add a sche-matic line from the number 8 to the number 9.

19 In the Add Schematic Lines dialog box, click Ortho.

20 In the drawing, add a schematic line from the number 9 to the number 10 at an angle of 15 degrees, and use the schematic curve connector to snap to the line.

21 In the Add Schematic Lines dialog box, click Close.


The schematic lines for the sanitary waste system are added to your diagram. If the lines are not exact, you can clean them up using the BREAK, EXTEND, and TRIM commands.


In this exercise, you added schematic lines to your diagram using both Iso-metric and Orthographic modes. You used schematic connectors to con-nect lines and, when drafting in Orthographic mode, you used the Com-pass to help you navigate. While you can toggle between Isometric and Orthographic drawing modes, it is recommended that you draw most of the lines in one mode. The mode is saved in the line properties and affects labels or symbols that you add to the lines. Next, you add schematic sym-bols to your diagram.

Exercise 2: Adding Laterals and Fixture Stacks

This exercise shows how to add schematic symbols to schematic lines in your diagram. The schematic symbols you add are in-line symbols because they are added to existing schematic lines. In-line symbols are anchored to sche-matic lines. If you move a line connected to an in-line symbol, the symbol moves with the line.

Schematic symbols are 2D objects. Like schematic lines, you can place sche-matic symbols in either Isometric or Orthographic mode. When you place a


schematic symbol on a schematic line using the schematic curve connector, the symbol reads the line’s mode (Isometric or Orthographic) and orients itself to the angle of the line.


Add a lateral to the waste line

1 Open the Plumbing Isometrics and Schematics tool palette and click the Add Schematic Symbols tool.

2 Select Plumbing Symbols - Isometric UK for Schematic Symbol, and click the Laterals category bar.

3 Select Lateral Right-Facing, and specify the following settings:

■ Verify that Mode is Ortho.■ Select Sanitary Black Water for System.■ Verify that ID is clear.■ Verify that Justification is Insertion Point.■ Clear Specify Rotation on Screen.■ Enter 180 degrees for Rotation.


4 In the drawing, select the schematic line at the number 1, and note that the Add Schematic Symbols dialog box shows that Mode has changed to Isometric.

When you anchored the schematic symbol to the line using the schematic curve connector, the symbol inherited the mode of the line (Isometric), and the Mode setting was updated to reflect the change. The symbol was placed in Isometric mode and read Isoplane Right from the line. When you place schematic symbols in Isometric mode, you have rotation options. The rotation options are not defined by degrees; they use Up, Down, Right, and Left. The option called Top uses a different set of rota-tions than the other options.


5 Verify that Iso Rotation is Right, and add a lateral at each location num-bered 2, as shown.

The laterals are anchored to the schematic lines to which they were added, and the Add Schematic Symbols dialog box remains open. The anchored relationship is maintained when the laterals are copied or moved.

Add a mop sink trap

6 In the Add Schematic Symbols dialog box, click the P-Traps category bar, and select P-Trap Connection 1.

7 Select Isometric, Isoplane Left for Mode.

8 In the drawing, place the symbol at the end of the schematic line num-bered 3, as shown.


The trap is added to the diagram, and the Add Schematic Symbols dialog box remains open.

Add a takeoff for the floor drains

9 In the Add Schematic Symbols dialog box, click the Takeoffs category bar, and select Floor Drain Takeoff.

10 Select Up for Iso Rotation.

11 In the drawing, place the symbol at the endpoint of the line numbered 4.

12 Repeat, adding the same symbol with an Up rotation at the left endpoint of the other horizontal schematic line, as shown.

13 In the Add Schematic Symbols dialog box, click Close.


The takeoff for the floor drains is added to the diagram.


In this exercise, you added schematic symbols to the horizontal schematic lines in your drawing. Next, you add symbols to vertical schematic lines.

Exercise 3: Adding Stack Fixtures

This exercise shows how to add schematic symbols to vertical schematic lines. The vertical lines were drawn using both the Isometric Right mode and the Orthographic mode to create the small turns at the ends of the lines that break out of the orthographic constraints.

You add schematic symbols to vertical schematic lines in the same way that you added them to horizontal lines; however, the rotations differ.


Add a wall-mounted water closet fixture

1 On the status bar, verify that Ortho, Polar, and Osnap are turned off.

2 Open the Plumbing Isometrics and Schematics tool palette and click the Add Schematic Symbols tool.


3 Select Plumbing Symbols - Isometric UK for Schematic Symbol, and click the P-Traps category bar.

4 Select P-Trap Connection 2, and specify the settings:

■ Verify that System is Sanitary Black Water.■ Enter WC for ID.■ Select Specify Rotation on Screen.

5 In the drawing, select a point midway on the vertical line numbered 1.


The symbol is anchored to the line at the insertion point, and the com-mand line prompts you for the rotation.

6 Move the cursor around the insertion point until you find the rotation that places the trap up and to the left, and click to place the symbol, as shown.

The p-trap symbol is added to the line at the proper rotation, and the Add Schematic Symbols dialog box remains open.

7 Repeat, adding a second P-Trap Connection 2 to the same location, but rotated so that the trap is pointing down and to the right.


8 Repeat, adding two P-Trap Connection 2 symbols midway on the vertical line numbered 2. Rotate one trap up and to the left, and the other trap down and to the right, as shown.

The p-trap symbols are added to the lines at the proper rotations.

Add traps for urinals

9 In the Add Schematic Symbols dialog box, select P-Trap Connection 3.

10 Enter UR for ID.

11 In the drawing, select the endpoint of one of the vertical lines numbered 3, rotate the symbol up and to the left, and click to place it.


12 Repeat, adding a P-Trap Connection 3 symbol, at the same rotation, to the other vertical line numbered 3, as shown.

The traps are added for the urinals.

When you add schematic symbols to vertical schematic lines, it is gener-ally easier to use the Specify Rotation on Screen option rather than the Up and Down rotation options. When you specify the rotation on the screen, you can move the cursor around the insertion point to help you visualize the various rotation angles.

Add a cleanout

13 In the Add Schematic Symbols dialog box, click the Cleanouts category bar.

14 Select Line Cleanout, and specify the following settings:

■ Enter WCO for ID.■ Clear Specify Rotation on Screen.■ Select Left for Iso Rotation.


15 In the drawing, select the left end of the horizontal line numbered 4, and place the cleanout, as shown.

The cleanout is added to the diagram.

16 In the Add Schematic Symbols dialog box, click Close.

Copy the cleanout to another line

17 In the drawing, select the cleanout, right-click, and click Basic Modify Tools ➤ Copy.

18 Select a point near the cleanout symbol, and select a second point near the schematic line numbered 5 to place the symbol, as shown.

The copied cleanout symbol jumps to the line and is anchored to it because it inherits a schematic line anchor from the original cleanout symbol.

When you move or copy an in-line symbol, such as the cleanout symbol in this exercise, it can move only along the line to which it is anchored, or to another line within the same system.


Finish adding schematic symbols for the sanitary waste system

On your own, do the following:

■ Add a P-Trap Connection 3 symbol, with an ID of DF for drinking foun-tain, to the vertical line numbered 6 in the drawing.

■ Add a Line Cleanout symbol to the short horizontal line numbered 6 in the drawing.

■ Add a P-Trap Connection 4 symbol, with an ID of LAV, to the two ver-tical lines numbered 7 in the drawing.

■ Add a P-Trap Connection 2 symbol to the two vertical lines numbered 8 in the drawing.

■ Add a Line Cleanout symbol to the short horizontal lines numbered 9 in the drawing.


In this exercise, you added schematic symbols for stack fixtures, fixture traps, and cleanouts to your schematic diagram. You added symbols to both horizontal and vertical schematic lines. When adding symbols to horizontal lines, you used the Right and Left rotation options. When add-ing symbols to horizontal lines, you used the Specify Rotation on Screen


option so you could visualize the various rotation angles by moving the cursor around the insertion point. Next, you add venting to the diagram.

Exercise 4: Adding Lines for Venting

This exercise shows how to draft vent piping for the riser diagram, using a new schematic system (Sanitary Vent) and a new schematic line style (Glued Pipe). In preparation for adding the schematic lines that represent vent pip-ing, you modify the line styles to define how crossing lines are displayed.

Currently, all of the lines in the riser diagram use the Standard schematic line style. In this exercise, you modify the Standard line style and the Glued Pipe line style to define which line will be displayed as broken when two lines of different styles cross.


Modify the Standard line style to define how crossing lines are displayed

1 On the Format menu, click Style Manager.

2 Expand Schematic Objects, and expand Schematic Line Styles.

3 Right-click Standard, and click Edit.


The style definition displays. On the General tab, you can modify the style’s name or description, or add schedule information. On the Designa-tions tab, you can define a list of values for the Designation ID of this schematic line style. When you add a schematic line with a style that has predefined values, you can choose one of the predefined Designation ID values from the Add Schematic Lines dialog box.

4 Click the Annotation tab.

5 Under Crossings, select Break Existing Line.


6 Enter 5.0 for Break/Overlap Width.

7 Enter 2 for Break/Overlap Priority.

The value that you enter for Priority, in conjunction with the Priority set-tings for the other schematic line styles used in your diagram, determines which line will be broken if two schematic lines of different styles cross one another. For example, a schematic line assigned to a line style with a Priority of 1 will break a schematic line assigned to a line style with a Pri-ority of 2. Later in this exercise, you assign the Glued Pipe line style a Pri-ority of 1.

8 Verify that Connection Node, Start, and End are set to None.

This will allow you to place a symbol at each connection or at the start or endpoint of each line.



Modify the Glued Pipe line style to define how crossing lines are displayed

10 In the left pane of Style Manager, right-click Glued Pipe, and click Edit.

11 Click the Designations tab, and click .

When you click New Designation (ID), a designation ID index is created. Enter a name next to the index number to create a Designation ID that can be used when adding schematic lines with the Glued Pipe line style.

12 Click to the right of the index number, and enter 40 for Designation (ID).

13 Repeat, adding Designation IDs of 50 and 60.


14 Click the Annotation tab.

15 Verify that Break/Overlap Priority is 1.

With its Priority specified as 1, a schematic line assigned to the Glued Pipe line style will break a schematic line assigned to the Standard line style, which has a Priority of 2.

16 Select None for Connection Node, Start, and End.

17 Click OK twice to close Style Manager.


The schematic lines are now broken where they cross.

Modify the display of a line

By using the Display Order command, you can control which line breaks another line of the same line style. The line numbered 1 in the drawing should appear to be positioned behind the others; however, it appears to be in front of them.

18 In the drawing, right-click, and click Basic Modify Tools ➤ Display Order ➤ Send to Back.

19 In the drawing, select the line numbered 1, and press ENTER.

20 On the View menu, click Regen.


The line is sent to the back and is broken by the other lines in the diagram.

Add vent piping

21 On the Plumbing Isometrics and Schematics tool palette, click the Add Schematic Line tool.

22 Specify the following settings:

■ Select Sanitary Vent for System.■ Select Glued Pipe for Style.■ Select Isometric, Isoplane Right for Mode.■ Select 40 for Designation ID.

The 40 mm value is available in the Designation ID list because you added it in step 12 of this exercise.

23 In the drawing, draw a vertical segment from each of the stacks numbered 1.5, selecting New Run after drawing each segment.


24 In the Add Schematic Lines dialog box, click New Run, and select 50 for Designation ID.

25 In the drawing, draw a vertical segment from each of the stacks numbered 2, selecting New Run after drawing each segment.

Although you could draw the vertical segments in Orthographic mode, use the Isoplane Right mode. When you label these segments in the next lesson of this tutorial, you will find that the labels orient themselves to the isoplane in which you drew the line.

26 Click New Run, verify that Designation ID is 50, and draw a horizontal segment from the number 3 to the number 4.

27 Click New Run, select 40 for Designation ID, and draw a horizontal seg-ment from the number 5 to the number 6.


28 In the Add Schematic Lines dialog box, click New Run, select 50 for Des-ignation ID, and draw a horizontal segment from the number 6 to the number 7.

29 In the Add Schematic Lines dialog box, select Isoplane Left and continue the horizontal segment until it meets the line between numbers 3 and 4.


30 Finish this exercise by using the TRIM, EXTEND, and BREAK commands to clean up the diagram, as shown.


The vent piping is added to the drawing. The schematic waste and vent diagram is now complete.


In this exercise, you added schematic lines to represent vent piping in your riser diagram. You used a new schematic line system definition (San-itary Vent) and a new schematic line style (Glued Pipe). In the previous exercise, you saw that the system definition controls the layer on which the line is placed, and that it holds a system abbreviation that can be used in labeling the lines. In this exercise, you saw that the schematic line style holds a Designation ID value, which can be used in labeling. You added values for 40, 50, and 60 mm IDs that you used in your riser diagram. You also saw that the schematic line style controls how the lines break at cross-ings. In this exercise, you modified the schematic line styles to define how crossing lines would be displayed. You have finished adding schematic lines and symbols to your riser diagram. Next, you add labeling to the dia-gram and adjust the scaling factors to set the height of the schematic sym-bols and labels.


Lesson 11: Annotating a Schematic Diagram

To complete the riser diagram, you add annotation such as labels, title marks, leaders, and revision clouds to your drawing.

Autodesk Building Systems provides two types of annotation: labels and doc-umentation symbols. When you want to display object information such as text and dimensions in your drawing, use labels. When you want to add information to your drawing such as title marks and revision clouds, use annotation symbols from DesignCenter. This lesson shows how to use both types of annotation, and how to adjust the scale of the schematic symbols and labels for plotting.


■ Exercise 1: Labeling and Scaling a Schematic Diagram

■ Exercise 2: Placing Annotations from DesignCenter

Exercise 1: Labeling and Scaling a Schematic Diagram

This exercise shows how to add labels to your drawing, and how to position multiple labels along the length of a schematic line. It also shows how to adjust the scale of both the schematic symbols and labels with one setting, and how to adjust the scaling for the objects separately.

Labels are Building Systems objects. They can inherit specific object proper-ties from attached objects, such as schematic lines or symbols, and display them as text. For example, a label can read the system abbreviation of a sche-matic line to which it is anchored, and display the abbreviation as text in your drawing. Labels can also read and display the Designation ID of an anchored object. If the anchored object is modified, the label updates dynamically. For example, if the Designation ID of the line is modified, the label attached to it updates to reflect the new ID.

When you add a label to an object, you specify the label style. The label style determines the text style, the position of the text on the object, the informa-tion that is displayed in the label, and how the label displays in your draw-ing. In this exercise, you add labels to your drawing using the Standard and System label styles.


Lesson 11: Annotating a Schematic Diagram | 177

Label a line using the Standard label style


2 In the drawing, select the schematic line numbered 1.



5 Place the label near the number 1 in the drawing, as shown.

The label is inserted on the line. The Standard label displays the Designation ID assigned to the schematic line, in this case 50.

Label a line using the System label style

6 Select the line you just labeled.

7 In the Add Labels dialog box, select System Label for Label Style, select One by one for Layout Method, and press ENTER.

8 Place the label to the right of the number 1 in the drawing, as shown.


The label is inserted on the line. The System label displays the abbreviation assigned to the schematic line in its system definition, in this case SAN.

Place multiple labels along the length of a line

9 In the drawing, select the line located below the number 2.


11 Select Space Evenly for Layout Method.

12 Enter 2 for Number of labels, and press ENTER.

13 Press ENTER to place the labels.


Two labels are spaced evenly along the line. If you change the length of the schematic line, the labels will maintain their even spacing.

Now that you have added labels to your diagram, you adjust the scaling factors for the schematic symbols and the labels.


Change the drawing scale to 1 = 75mm

The labels you placed in your diagram inherited specific properties from the lines to which they were anchored, but the size of the labels was deter-mined by two drawing setup values: Drawing Scale and Annotation Plot Size. These scaling variables also control the size of the schematic symbols in your diagram. Changing either scaling value changes the size of both the schematic symbols and the labels.

NOTE In this tutorial, the scaling values are adjusted after schematic sym-bols and labels have been placed in the diagram in order to illustrate the effect of changing the values. In your own projects, set the scaling values before you begin your diagram in order to work more efficiently.

15 On the Format menu, click Drawing Setup.

16 Click the Scale tab.

17 Select1:75 for Drawing Scale, and click OK.


The scale of both the schematic symbols and the labels changes to 1:75.

18 Press ENTER to repeat the Drawing Setup command.

19 On the Scale tab, enter 4 for Annotation Plot Size, and click OK.


The scale of both the schematic symbols and the labels changes to 4 mm.

20 Press CTRL + Z once to undo the modifications you made to the Annota-tion Plot Size, in preparation for scaling the schematic symbols and labels using a different method.

As you have seen, Drawing Scale and Annotation Plot Size affect sche-matic symbols and labels in your diagram. If you want to adjust the scale of schematic symbols and labels separately, you must modify their assigned styles. To change the scale of a schematic symbol that has been placed in Isometric mode, use the Scale command. To change the scale of a label, create a text style that has a fixed height, and apply it to the label style.

Edit a schematic symbol to change the scale

21 In the drawing, select one of the laterals, right-click, and click Basic Mod-ify Tools ➤ Scale.


22 Select a point near the lateral.

23 On the command line, enter 0.5 for the scale factor.

The lateral is reduced to 50% of its original size, and it remains anchored in its original location.

Create a text style with a fixed height

24 On the Format menu, click Text Style.

25 Click New.

26 Enter Tutorial Text for Style Name, and click OK.

27 Select Arial for Font Name.

28 Enter 500 for Height.


29 Click Apply, and click Close.

Next, you apply this new text style to the schematic label styles.

Apply the text style to the schematic label styles

30 In the drawing, select the label SAN, right-click, and click Edit Label Style.

The Label Style dialog box opens. Because you selected a System label (SAN), any changes you make in the Edit Label Style dialog box will affect the System label style.

31 Click the Label Style Annotation tab.

32 Select Tutorial Text for Text Style.


33 Click OK.

The text style for System labels is now Tutorial Text.

Next, you apply this fixed-height text style to the Standard label style.

34 In the drawing, select the label 50, right-click, and click Edit Label Style.

35 On the Label Style Annotation tab, select Tutorial Text for Text Style.

36 Click the Label Style Offset tab.


37 Select Force To Horizontal Justification, and click OK.

The text style for Standard labels is now TutorialText.

TutorialText has a fixed height of 500 mm, regardless of the values entered for Drawing Scale and Annotation Plot Size. Also, by selecting Force To Horizontal Justification, you ensure that the Standard label style displays horizontally, regardless of where the label is anchored.

Offset a label from its anchored object


39 In the drawing, select the trap next to the number 3.




42 Place the label below and to the right of the number 3 in the drawing.

43 On your own, finish labeling the schematic diagram.


In this exercise, you added labels to schematic lines using the Standard and System label styles, and you placed multiple labels along the length of a line using the evenly-spaced mode. The labels inherited specific prop-erties from the lines to which they were anchored, displaying information such as the designation ID or the system abbreviation. You also changed the scale of labels and schematic symbols in your diagram using the Draw-ing Scale and Annotation Plot Size settings. To change the scale of these objects individually, you used the Scale command on a lateral symbol and you applied a fixed height text style to the System and Standard label styles. Finally, you finished labeling the schematic symbols in your dia-


gram. Next, you add annotation symbols from DesignCenter to your drawing.

Exercise 2: Placing Annotations from DesignCenter

This exercise shows how to add documentation symbols such as title marks and leaders to your drawing. Documentation symbols are stored as drawings in DesignCenter. They can be accessed and inserted into your drawing using the documentation content commands in Autodesk Building Systems. When you use insert documentation symbols from DesignCenter, follow the prompts on the command line to provide input for annotation variables such as text, location, angle, and number of symbols to be added.

The scaling of the symbols is controlled by the Drawing Scale and Annota-tion Plot Size but, unlike labels, the scaling is not dynamic. After an annota-tion is placed in a drawing, its scale is constant. Annotation symbols that dis-play text, such as title marks, elevation marks, and section marks, use the cur-rent text style to create their text. In this case, the current text style is Tuto-rialText, which was specified in the previous exercise.

Like the schematic lines and symbols in your diagram, annotation symbols are layer keyed. The layer standard used in Autodesk Building Systems is a modified version of the AIA layer standard. Under this standard, a layer name is made up of four fields: Discipline, Major, Minor, and Status. For example, according to the Plumbing layer standard, the layer for a domestic water pipe is P-Domw-Pipe. A layer key override is used to modify, or override, part of the layer name.

The layer keying for the annotation symbols in DesignCenter places them on layers that are set up with a Discipline value of A to denote Architectural annotation. In this exercise, you use a layer key override to place all the annotation on layers with a Discipline of P to denote them as Plumbing lay-ers.

NOTE When a layer key override is in effect, it applies to all objects added to the drawing.



Set the layer key Discipline to Plumbing


2 Click the [...] button to the right of Discipline Designator.

3 Select P, “Plumbing”, and click OK.

4 Click OK.

Add a title mark

5 Open the Callouts tool palette and select the TitleMark tool.

6 Specify a point in the lower-left corner of the drawing to locate the title mark.

7 Move the cursor to the right and specify the endpoint of the title mark line.

The title mark is placed in your drawing with generic number, title, and scale attributes.

8 Select the VIEWNUMBER text, right-click, and then click Edit Attributes.

9 In the Enhanced Attribute Editor dialog box, enter 1 for Value.


10 Click OK.

11 Select the VIEWTITLE text, right-click, and then click Edit Attributes.

12 In the Enhanced Attribute Editor dialog box, do the following:

■ Under Tag, select SCALE and enter 1 = 75 mm for Value.■ Under Tag, select TITLE and enter Partial Waste/Vent Diagram for

Value.

13 Click OK.


The title mark is inserted into the drawing on layer P-Anno-Ttlb.

Add a revision cloud

14 Open the Architectural Annotation tool palette and click the Medium Arcs & Tag tool.

15 Specify a point near the top of the drawing and, holding the mouse button down, move the cursor counterclockwise in a circle to draw a revision cloud, closing on the starting point.

16 Specify a point above and to the right of the revision cloud for the center point of the revision tag.

17 In the Edit Attributes dialog box, verify that is 1.


18 Click OK.

Add a leader line and text

19 On the Annotation and Utilities tool palette, click the Text (Straight Leader) tool.

20 Select a point on the right side of the revision cloud, move the cursor a short distance up and to the right and click.

21 Move the cursor a short distance to the right and click.

22 Press ENTER to end the line.

23 On the command line, enter ADD LAVS IN THIS AREA.


The text is inserted into the drawing, but is too small to read. You can resize the leader text.


Resize the label

25 Zoom in to the new text.

26 Select the text, right-click, and click Scale.

27 Press ENTER to accept the existing basepoint.

28 Enter 500 for the new height, and press ENTER.

29 Select the text, right-click, and click Justify.

30 Enter ML and press ENTER.

The leader and text are resized and aligned.

31 Select the leader and verify that it is on layer P-Anno-Note.

NOTE It is important to remove the layer key override before you close this drawing. Another person opening this drawing will see no indication that a layer key override is in effect, and is likely to start drawing with the override in place.


Reset the layer key


34 In the Override column, select P, and then press the BACKSPACE key to delete this override.

35 Click OK to close the Layer Key Overrides dialog box.



In this exercise, you completed your riser diagram by adding documenta-tion symbols such as a title mark and a revision cloud. You used a layer key override to place all the annotation on layers with a Discipline of P to denote them as Plumbing layers. When you finished placing annotation symbols, you removed the layer key override as a matter of good practice.
