Pipe Design Overview Civil 3D approaches pipe design through the use of a pipe network. A pipe network consists of structures and pipes which interact with each other as well as other objects in the drawing. The appearance and behavior of pipes and structures is controlled by styles. This arrangement is consistent with other design systems we have studied in Civil 3D.

A typical pipe system design consists of pipes and structures that come in many shapes and sizes. On the other hand, from project to project most designs utilize the same set of shapes and sizes. Civil 3D provides a system of storing, organizing, and managing these common components through a parts list. A parts list can be reused on each new project but is also very flexible to meet unique design requirements.

Pipe system designs typically follow a set of design parameters such as minimum and maximum slopes, minimum and maximum cover, etc. These parameters are also usually similar from project to project. Civil design handles this consideration through design rules for pipes and structures. Design rules can be established for one project and then reused for future projects as well.

Civil 3D parts lists and design rules along with its capability to quickly and dynamically create, modify, and annotate your pipe networks will allow you to efficiently perform pipe designs for your land development projects. The interactive capabilities of Civil 3D objects is also present with pipe networks. Therefore you will have the freedom to modify virtually any portion of your overall land development model and have your pipe networks respond dynamically to the changes you make. Pipe network annotations are also dynamic so you can concentrate on the design itself and let Civil 3D address any revisions that are needed to your pipe or structure labels in both plan and profile views.

Parts Lists As mentioned, the typical pipe system design consists of many types and sizes of pipes and structures. The details of these components can be very different from one engineering office to another or from one locality to another. On the other hand, most offices perform pipe system design using very similar components from project to project. The Civil 3D parts list is a very effective approach to providing effective access to a library of components that you commonly use. Parts lists can be accessed through the Settings tab of the Toolspace.

The Network Parts List dialog consists of an Information tab where you can specify a Name and Description for your parts list.

The Pipes and Structures tabs are where you compile the standard pipes and structures that you would like to use for a particular type of design. You begin compiling the list by first adding a part family. This is done by right-clicking on the name of the parts list and selecting Add Part Family.


4

A part family is a group of components that share similar characteristics such as material, shape, and configuration. Part families are stored in a part catalog that installs along with Civil 3D.

Once you have added a part family to your parts list you must then add one or more part sizes under that family. This is done by right-clicking on the name of the part family and selecting Add part size.

This will launch the Part Size Creator dialog where you will specify the parameters for a given part size. Not all of the parameters can be modified. You can add additional parameters to the part size by pressing the Append Property button in the Part Size Creator dialog. The properties that are available will depend on the part family that you are working within.


5

Once you have provided all of the parameters for a given part size you can press OK to add the part size to the parts list. Each part size can be assigned a style, rules, and a render material style to control its appearance and behavior.

You can add as many sizes as you like to a given part family. The parameters that are stored in the part size can be modified once the part has been placed in the network so you don’t have to create an entry in the parts list for every possible scenario. Instead you should build a library of your most commonly used parts and sizes and rely on the ability to modify the parts to handle unique design situations.

Pipe Network Creation Design Rules Every pipe system design is governed by design constraints to ensure that the system works properly. Common design constraints such as pipe slope and cover can be applied as you design through the use of Civil 3D rules. Rules will control the positioning of the pipes and structures as you design and will also notify you if any violations have occurred. Rules are accessed on the Settings tab of the Toolspace. There is a set of rules for structures and for pipes.


6

The Pipe Rules dialog consists of an Information tab where you can specify a Name and Description for a given set of rules.

The Rules tab is where you specify the rules themselves.

The rules that govern pipe design can be summarized as follows:

Slope • Minimum Slope - This rule defines the minimum slope for the pipe, expressed in percent. During layout,

a pipe will be created according to this minimum slope rule value. You can still edit the pipe as desired, breaking the minimum slope rule, but a rule violation occurs for that object.

• Nominal Slope - This rule defines the nominal slope for the pipe, expressed in percent. Nominal slope is

always greater than minimum slope. This is the desired slope of the pipe. During layout, the pipe will be created at this slope, unless minimum/maximum cover forces the pipe towards a steeper or shallower slope.


7

• Maximum Slope - This rule defines the maximum slope for the pipe, expressed in percent. During layout, a pipe will be created according to its maximum slope rule value. You can still edit the pipe as desired, breaking the maximum slope rule, but a rule violation occurs for that object.

• Apply Maximum Slope - This rule lets you disable the Maximum Slope rule. When the Apply Maximum

Slope rule is set to false, the Maximum Slope rule is ignored.

Cover • Minimum Cover - This rule represents the minimum cover of soil over the pipe, based on the surface

being referenced by that pipe. During layout, a pipe will be created that attempts to maintain the minimum cover, unless the minimum/maximum slope is reached, forcing the cover to be less than the minimum. This rule is also used to determine the elevation of the beginning of the pipe. If the pipe is edited so that its cover is less than the minimum cover value, a rule violation occurs for that object.

• Maximum Cover - This rule represents the maximum cover of soil over the pipe, based on the surface

being referenced by that pipe. During layout, a pipe will be created that attempts to have less than the maximum cover, unless the minimum/maximum slope is reached, forcing the cover to be more than the maximum. If the pipe is edited so that its cover exceeds the maximum cover value, a rule violation occurs for that object.

Pipe Length • Maximum Pipe Length - This rule defines the maximum length of the pipe. When this rule is set, you can

still draw pipes that exceed the maximum pipe length. However, when you do this, a rule violation occurs for that object.

The Summary tab can be used to manage many of your pipe rules settings from one location.

The Structure Rules dialog has an Information tab where you can specify a name and description for your set of structure rules.

The Rules tab is where you specify that actual rules for your structures.


8

The rules that govern structure design can be summarized as follows:

Rim • Rim Elevation Adjustment - This rule applies only to junction structures and defines the adjustment for

the structure rim elevation. This value is only used when a surface is referenced by the structure. When the structure is first created, or the structure is re-sized, the rim will adjust itself to this value above or below the reference surface (+/-). This value has no affect when no surface is being referenced. This value will affect the structure rim when the part is moved or when the surface elevation is changed during editing.

• Adjust Rim Elevation To Surface On Resize - This rule applies only to junction structures. It lets you

disable the Rim Elevation Adjustment rule when a junction structure is resized. This rule gives you the ability to manually edit a junction structure’s rim elevation independent of a surface. When this rule is set to false, and you edit the structure, the structure will still adjust its size to match pipe depths, however, the Z position of the structure does not change. To use this feature, set the structure’s Adjust rim elevation to surface on resize value to false, then move the structure to reposition its Z-insertion points as desired, then right-click the structure and use the Resize to Model command. This adjusts the structure’s sump depths as needed to match the new pipe positions.

Sump • Sump Depth - This rule defines the depth of the sump area of the structure. This is the depth from the

lowest invert of the lowest pipe to the sump (inside bottom) of the structure. This value is used during creation and editing of the structure, or when any new pipes are connected to it or removed during editing.

The Summary tab can be used to control many of the settings for your structure rules from one location.

Creating Pipe Networks by Layout Once your parts lists and rules are in place you are ready to begin creating pipe networks. This is done by clicking on the Pipes pull-down menu and selecting Create By Layout.


9

This will first launch the Create Pipe Network dialog.

Enter a name and description for your new pipe network.

Choose a parts list that you will select components from.

Choose a reference surface to set the rim elevations for your structures and to check cover on the pipes.

Choose a reference alignment to call out structures by station and offset.

Choose label styles that will be applied to the pipes and structures as they are created.

Assign layers to the different components of your pipe network.

Once you have completed all of the information in the Create Pipe Network dialog you can press OK to launch the Network Layout Tools toolbar. You will use the commands on this toolbar to set the stage for your design and to create and modify pipes and structures.

The commands and functions that are available on the Network Layout Tools toolbar can be summarized as follows:

Pipe Network Properties

Opens the Pipe Network Properties dialog box, where you can control defaults and properties of the pipe network, such as the referenced parts list, object references, and more.

Select Surface Opens the Select Surface dialog box, where you can


10

specify the surface referenced by the current pipe network. When a surface is selected, it is used to determine depths and elevations of pipe network parts, based on rules for the part. If there are no surfaces in the drawing, this button is not available. Changes made to this selection will not affect parts already created in the pipe network.

Select Alignment

Opens the Select Alignment dialog box, where you can specify the alignment referenced by the current pipe network. If there are no alignments in the drawing, this button is not available. Changes made to this selection will not affect parts already created in the pipe network. The alignment provides station offset values for the pipe network parts.

Parts List

Opens the Select Parts List dialog box, where you can specify the parts list referenced by the current pipe network. The parts list controls the set of pipes and structures that are available for use in the current pipe network.

Structure List Specifies the type of structure currently selected for insertion into this pipe network.

Pipe List Specifies the type of pipe currently selected for insertion into this pipe network.

Pipes and Structures

When Pipes And Structures mode is selected, a structure is inserted at the first selection point, followed by a pipe. Subsequent selection points continue to insert structures connected to pipes.

Pipes OnlyWhen Pipes Only mode is selected, you are prompted to select the start and end points for each pipe you insert. You can only insert pipes in this mode.

Structures OnlyWhen Structures Only mode is selected, you are prompted to select the insertion points for each structure you insert. You can only insert structures in this mode.

Downslope Pipe slope set to downhill.

Upslope Pipe slope set to uphill.

Delete Pipe Network Object

Deletes the specified pipe network part from the drawing.

Undo Reverses the last action.

Redo Repeats the last action. Redo is limited to one operation.

Pipe Network Vistas

Opens the Panorama window. Lets you display and edit the pipe network data in vistas. There is a vista for pipe object data and a vista for structure object data.

There are several commands on the Network Layout Tools toolbar that you will use often to perform pipe network design. These are explained in more detail below.


11

Pipes And Structures – This command will prompt you for a series of points and will create a new structure at each point that you select. Pipes will be connected between the new structures. The ‘SO (station and offset) transparent command is helpful when placing structures along a road alignment.

Pipes Only – This command will create new pipes only. The command has a built in type of object snap that will recognize structures.

Snap marker

It also has a “snap” that recognizes other pipe objects.

Snap marker

When you connect one pipe to another directly a null structure is placed at the junction.


12

Structures Only – This command will create new structures only. You can use the pipe “snap” to connect structures to pipes that already exist in your drawing.

` `

Downslope and Upslope – Use this toggle to control which direction the slopes in your design rules are applied. For example, if you are drawing pipes in an uphill direction, you should toggle to Upslope. Otherwise your pipes will become extremely deep based on a downward slope.

Showing Pipe Networks in Profile Views At some point you will want your pipe network to appear in a profile view for design and documentation purposes. This is done by clicking on the Pipes pull-down menu and selecting Draw Parts in Profile View.

You will be prompted to select the parts in the drawing area that you would like to show in a profile view. You can also enter “E” for entire network.

Finally you will be prompted to select the profile view where you would like the parts to be drawn.


13

Another approach is to select one or more pipe network parts in the drawing area, right-click, and select Draw Parts in Profile View.

In this case you will not have “entire network” as an option. The parts that you have selected will be added to the profile view.

Pipe Network Display As you might guess, the appearance of your pipes and structures in both plan and profile view is controlled by styles. This section is an introduction to the many intricacies of pipe and structure styles. An in-depth discussion of pipe and structure styles is reserved for advanced training.

Pipe Styles Pipe styles can be accessed through the Settings tab of the Toolspace.

They can also be created or modified from within the Pipe Properties dialog.


14

The Pipe Style dialog has six tabs which can be summarized as follows:

Information – Use this tab to specify a Name and Description for your pipe style.

Plan – Use this tab to control the geometry and appearance of the pipe in plan view.

The options available in this dialog can be summarized as follows:


15

Pipe wall sizes • Use part dimensions – shows the inside and outside wall lines according to the properties of the part. • User defined – shows the inside and outside wall lines according to user specified dimensions. • Size options – The size of the pipes can be controlled by drawing scale, percentage of screen, or can be

set to the absolute dimensions supplied under Inner diameter and Outer diameter. Pipe Hatch Options

• Hatch to inner walls – If a hatch pattern is applied, it will fill the “void” of the pipe between the inner wall lines.

• Hatch to outer walls – If a hatch pattern is applied it will extend from outer edge to outer edge. • Hatch walls only – If a hatch pattern is applied it will be confined between the inner and outer walls on

each side of the pipe. Pipe end line size

• Draw to inner walls – The end line will be drawn across the end of the pipe from inner wall to inner wall. • Draw to outer walls – The end line will be drawn across the full diameter of the pipe from outer wall to

outer wall. • User defined – The end line will be drawn according to user defined dimensions.

• Size options – The size of the end line can be controlled by drawing scale, percentage of screen, or can

be set to the absolute dimension supplied under inch:.

The Profile tab is used to control the display of the pipes in profile view.

This tab is identical to the Plan tab with the exception of the Crossing pipe hatch options. These options function identically to the Pipe hatch options.

The Section tab controls the appearance of the pipe in cross section. It contains only the Crossing pipe hatch options.


16

The Display tab controls the visibility of each component of the pipe as well as the layer, color, linetype, and other AutoCAD properties.

The Summary tab can be used to control many of your pipe style options from one location.

Structure Styles Structure styles can be accessed from the Settings tab of the Toolspace.


17

They can also be accessed from within the Structure Properties dialog.

The Structure Style dialog contains five tabs which can be summarized as follows: The Information tab can be used to specify a Name and Description for your structure style.

The Model tab is used to control the appearance of the structures in 3D view.


18

The display of the structure can be based on information in the catalog or a simple 3D part.

The Plan tab is used to control the appearance of the structure in plan view.

The structure can be represented by the outer boundary of the catalog part or by a user-defined block that exists in the drawing. The x and y scales of the block can be controlled by the drawing scale, the part dimensions, and several other options. This provides a lot of flexibility when you are choosing how to represent the structure in the


19

drawing. Part masking causes the structure to “hide” objects that exist behind it creating a “clean” appearance to the pipes and structures that exist at a junction.

The Profile tab is used to control the display of the structure in profile view.

The structure can be represented by the outer boundary of the catalog part or by a user-defined block in the drawing. As with the Plan tab, the scales of a user-defined block can be controlled using a number of factors.

The Display tab is used to control the visibility of the structure components as well as the layer, color, linetype, and other AutoCAD properties.


20

The Summary tab can be used to control many of the settings for your structure style in one location.

Pipe Network Editing Pipe networks can be edited using a number of approaches. The Network Layout Tools toolbar can be used to add and delete new parts. The Panorama can be used to perform numerical editing to adjust the inverts, slopes, and rim elevations of your network. Network parts possess special grips that can be used to perform graphical editing while maintaining the design integrity of the network. And finally, Civil 3D provides several right-click menu commands that you will find helpful when editing your pipe networks. This section discusses all of these approaches.

Using the Network Layout Tools The Network Layout Tools toolbar that we learned about in the previous section can also be used to edit networks that already exist. It can be launched by clicking on the Pipes pull-down menu and selecting Edit.


21

You can also launch the toolbar by selecting a network part in the drawing, right-clicking, and selecting Edit Network.

Or you can right-click on the name of the network in Prospector and select Edit.

All of these approaches will launch the Network Layout Tools toolbar. For a summary of all of the commands that are available refer to the Pipe Network Creation section of this chapter.

Graphical Editing Pipe network parts are equipped with special grips that allow you click and drag your pipes and structures to make quick visual edits. In plan view, structures can be moved by using the square grip usually located near the center of the structure symbol.

The circular grip is used to rotate the structure about its insertion point.


22

In profile view, the triangular grip can be used to adjust the rim elevation of the structure.

For pipes, a triangular grip in plan view can be used to extend or shorten the pipe along its own direction.

The square grip at the endpoint can be used to change the location of the end of the pipe.

The square grip at the midpoint can be used to move the pipe while maintaining its current direction.


23

The triangular grip at the midpoint can be used to adjust the diameter of the pipe.

In profile view, the triangular grip at the end of the pipe can be used to “slide” the end of the pipe up or down while maintaining its current position in plan view.

The square grip at the midpoint can be used to move the entire pipe up or down while maintaining its slope and current position in plan view.


24

Numerical Editing Once your network is in place, you will often need to make minor adjustments to the inverts and rim elevations based more on actual numbers than on the visual representation of the design. To accomplish this, you can use the Pipe Network Vistas button on the Network Layout Tools toolbar.

This will launch the Panorama with two vistas: Pipes and Structures. Using these vistas you can modify the style of the part as well as the geometric parameters that define its location and size.

The Status column in each vista will inform you if any design rules have been violated. A check mark means that all design rules have been met. A check with a red circle and slash means that an issue exists. You can hover over the status icon to view the details of the rules violation.


25 5

Right-Click Menu Commands Right-Click Menu Commands There are several right-click menu commands that you will find helpful in creating and editing your pipe networks. To access the commands, select a part in the drawing area and press the right mouse button. There are several right-click menu commands that you will find helpful in creating and editing your pipe networks. To access the commands, select a part in the drawing area and press the right mouse button.

Based on the current condition of the part you have selected different commands will appear in the menu. The commands that you can use are as follows:

Swap Part – Exchanges the part you have selected with another in the parts list.

Resize to Model – Updates the rim and sump elevations of the structure you have selected based on any changes to the surface, the location of the structure, or the inverts of the pipes that are connected to it.

Connect to part – Connects the part you have selected to another part in the drawing


26

Disconnect from part – Disconnects the part you have selected from another part in the drawing.

Pipe Network Labels Now that we have discussed the process of designing a pipe network we will now look at conveying design information through pipe network labels. As with other features pipe network annotations are style-based and are dynamically linked to the objects they label. This means you can create annotation styles that meet your CAD standards and concentrate on the design itself rather than manually editing text.

Pipe Network Label Styles Pipes and structures, the two main components of a pipe network, each have a set of styles that control their annotations. These styles can be accessed from the Settings tab of the Toolspace.

They can also be accessed from the Add Labels command in the Pipes pull-down menu.

The Pipe Label Style and Structure Label Style dialog boxes are nearly identical, each containing 5 tabs which can be summarized as follows:


27

The Information tab can be used to specify a Name and Description for your pipe or structure label style.

The General tab can be used to configure general properties for all the components of the label style such as layer, text style, text height, etc.

The Layout tab is used to compile the components of the label and configure each component according to your graphical standard.

The Dragged State tab controls the appearance of the label when it is moved from its original position.


28

The Summary tab can be used to control many of the label style settings from a single location.

Creating Pipe Network Labels You can create pipe network labels by clicking on the Pipes pull-down menu and selecting Add Labels.

This will launch the Add Labels dialog. Under Label Type you can choose to label individual components or the entire network at once.


29

Once you have chosen the Label Type and the styles you would like to use, you can press the Add button to create the labels.

You will then be prompted to select a part in the network you would like to label. If you have chosen a single part Label Type, the part you have selected will be labeled. If you have chosen an entire network Label Type, all of the pipes or structures will be labeled.


30

Once a label is in place, you can change it using a number of approaches. One approach is to select the label, right-click, and select Label Properties.

From the Label Properties dialog you can change the style of the label.


31

For pipe labels, the right-click menu also has a Flip Label command that can be used to move the label to the other side of the pipe.

Labels can also be modified graphically by using grips. For a pipe label you can use the diamond shaped grip to slide the label along the pipe.

For both pipe and structure labels, the square grip can be used to move the label from its original position. This will activate the dragged state.

When a pipe or structure label is in dragged state, the circular grip can be clicked to return it to its original position.


32

Pipe Network Reporting The LandXML reporting capabilities of Civil 3D can also be used for generating pipe network reports. To begin the reporting process, you can click on the General pull-down menu and select Generate Report.

You will then be prompted to choose either the Pick option or the Filter option. The Pick option will ask you to select the pipe network in the drawing area. The Filter option will launch the Generate Report dialog where you can select the pipe network that you would like to create a report for.

The Autodesk LandXML Reporting dialog will then appear. You can use the Forms tab to select the form that you would like to use to format the report.


33

The Output tab will display the actual formatted report.
