CHAPTER 2


2 Draft Features

The Draft module within PDMS allows the designer to generate fully annotated engineering drawings directly from data in the PDMS Design model. Furthermore, the Draft module allows drawings to be easily updated to reflect design model changes. Chapter 2 outlines the facilities that may be utilised within Draft to produce drawings.

2.1 General

The Draft Graphical User Interface (GUI) has been designed to allow the User to generate and retrieve industry standard engineering drawings efficiently. The following features of Draft aid the drawing production process:

The designer can add dimensioning and other annotations with information taken directly from the design model.

The Draft drawing can be created with any view angle and the representation of the drawing graphics is controlled by representation rules that are pre-defined by the project administrator.

Various levels of wireline and hidden line removal views can be used. Sectional views can be generated by the creation of flat or stepped section planes.

The scale of the drawing can be selected from a set of Metric, Architectural and Engineering values, with the option of an automatic scale selection to use the largest appropriate scale.

A label can be attached to any design element and used to display any attribute of the design element. The format, content and appearance of the labels are controlled by the designer. Direct reference to the design data, combined with a simple update operation, ensures that the annotation always reflects the current state of the design model.

The ability to employ Autotagging is a quick solution for automatically generating labels that match a tagging rule. The rule determines the type of label and the design items the labels will be applied too.

A dimension is calculated directly from the design model, the Designer can control the format, content and appearance of the dimensions. As with labelling, direct reference to the design data ensures that the annotation always reflects the current state of the design model with a simple update operation.

2D drafting allows the designer to generate additional 2D annotation and graphics to form drawings. As with other Draft data, 2D annotation can be linked to design data and can be updated to follow the changes that occur in the design model.

2.2 Automatic Drawing Production (ADP)

Automatic Drawing Production is not covered in this training course. As the title of the application infers, this aspect of Draft enables the Designer to produce annotated drawings automatically. A set of rules determine how the annotation is generated. The drawings can be edited, if necessary, using the normal editing options in Draft. There are a number of ADP applications for different disciplines.

Refer to TM-1206 Drawing Production (Advanced)

www.aveva.com


AVEVA PDMS Area Based Automatic Drawing Production enables standard production drawings, complete with annotation, to be automatically generated based on engineering disciplines and Plant areas.

Refer to TM-1209 Area Based Automatic Drawing Production

Refer to TM-1305 Area Based Automatic Drawing Production Administration

2.3 AutoDraft

AutoDraft is not covered in this training course. This application imports drawings directly from Draft into AutoCAD. However, it should be noted that once this action is done, the drawing in AutoCAD has no direct link to the design model or data – thereby not allowing drawing updates to occur from the design model. Symbols and drawing frames can be exported from AutoCAD directly into DRAFT.

Refer to TM-1206 Drawing Production (Advanced)

2.4 Draft Administration

Draft Administration is not covered in this training course. Using this application, the Project Administrator is able to specify and customise the Draft environment. This includes setting default attribute values, creating drawing frames (commonly referred to as backing sheets), symbols and labels. The Administrator will also set the representation rules, labelling rules, naming conventions, lines styles, hatch patterns and available symbols.

The Administration Option is only available to Free Users or Members of the DRAFTADMIN Team.

3 Draft Workflow & Training Outputs

Chapter 3 highlights the Draft workflow in general terms, together with expected training outputs i.e. a discipline specific annotated and dimensioned drawing. Beginning with an introduction to the Draft module interface and basic User manipulation of the components, the proceeding chapters will build on the workflow below to give the Trainee User a clear appreciation of PDMS Draft and the requirements for effective drawing production.

3.1 Draft Workflow: Overview

1. Construct Draft Database Hierarchy As found with other areas of PDMS, Draft has a strict hierarchy that needs to be followed – this is shown by the hierarchical tree below.

The Draft hierarchy is formed as the drawing is created. In the first instance, the User creates a Draft Department beneath the World. Draft encourages the User to adopt a defined but flexible workflow. In this context and on creation of the Department, the User is presented with an opportunity to automatically create the next element, a Registry, and/or set up attributes of the Department.

Refer to Chapter 5 for detailed information on creating a Draft Hierarchy

2. Define Drawing Size, Units, Text & Pens The User is able, via the Department Attributes to define the Paper Size and appropriate Backing Sheet, together with Units (metric or imperial), Pens (colour and style), Font and any bespoke Intelligent Text to be used. Any drawings created in this Department will use these defined attributes as the default setting unless otherwise specified on creation.

Refer to Chapter 5 for detailed information on defining DEPT Attributes

3. Create Drawing & Sheets: from Template or Explicitly In a similar fashion to Step 1, the User is able to automatically create a drawing and continue the Draft hierarchy on Registry creation. The User is able to create a drawing either Explicitly or From Template. From Template - Allows the selection of a pre-defined Drawing, Sheet & Views. Explicitly - Allows the User to define each element of the drawing – Drawing, Sheet and Views - on creation.

4. Define a View: User-Defined, Limits-Defined or Detail

Views are essentially windows within a Sheet in which the model data can be displayed. There are a number of different ways in which Views can be created and setup. Limits-defined: Allows views to be created by specifying corner points on the Sheet User defined: Allows views to be created with the size and position determined using cursor clicks in the sheet area Detail: Allows detailed views to be created by selecting an element, followed by the definition of the size and position Predefined: Presents a range of predefined view setups, where the view positions are fixed, and the view directions can be specified.

Refer to Chapter 7 for detailed information on View creation

5. Populate the View As in Design, a Drawlist must be populated to determine which items are to be displayed within the View. The User is able to populate the Drawlist by referencing elements from the Design Model. Following the population of the Drawlist, the User is able to define an appropriate Scale. This is aided by an Auto Scale function; calculating the largest scale that will allow the entire Drawlist to fit within the View before the User sets the scale to the nearest standardised format. On updating the design, a View of the defined Drawlist is illustrated.

Refer to Chapter 7 for detailed information on View population.

6. Dimension & Label the Drawing

In the Draft Explorer, under the VIEW element, a series of LAYE (Layer) elements exist where Dimensions, Labels and Notes can be stored. The User is able to create Linear/Angular Dimensions and Labels through graphical interaction with the View. Intelligent Text, where notation is automatically derived from the database, can be used. This is highlighted by the annotated dimension Projection Lines below; centre line notation and equipment names have been applied via a reference to the design element.

CHAPTER 4


4 Draft Overview

Chapter 4 aims to introduce the Draft application in regards to access, the user interface and the Draft viewing and manipulations controls.

4.1 Entering a Draft Session

To start AVEVA PDMS and login to the Draft Module, the User must select the following or as directed by the Trainer:

& or AVEVA Plant > Design > PDMS 12.1 > Draft from the Windows Start Menu Login using the details provided by the Trainer, for example:

Project: Training Username: A-Piper Password: A MDB: A-PIPING

Click the Login button On loading PDMS Draft, the following default screen layout is displayed:


20

www.aveva.com


4.2 Current Element Definition & Explorer Windows

When working in any database, PDMS is always located at a specific element in that database - the Current Element (CE). The Draft application allows the User to navigate within the Draft and Design Database, thereby allowing a Design Element to be defined as the Current Element. To display the Draft and Design Explorer windows the following is selected: Display > Explorers prior to selecting (by a tick) the required Explorer.

For example, the Design Explorer is displayed using: Display > Explorers > Design Explorer.

For information on the manipulation and docking of windows please refer to TM-1001 AVEVA Plant (12 Series) PDMS Foundations.


21

www.aveva.com


4.3 Displaying Toolbars

To display toolbars, the right mouse button is clicked while the cursor is located over the main bar menu. The following pull down will be displayed allowing the selection of the relevant toolbars to be displayed.

4.4 Displaying the Draft Drawing Sheet

The Draft Drawing Sheet can be accessed via the Draft Explorer. Starting with the selection of a Department (DEPT), the hierarchy can be expanded using the + sign to show owned Registries (REGI) and expanded thereafter to display owned Drawings (DRWG) and Sheets (SHEE).

The Working Sheet toolbar is normally used to display Drawing Sheets

Used to display Drawing Sheets

Used to remove Drawing Sheets The display button is „greyed out‟ where a sheet is selected from a read only database or the CE is not an appropriate element.

Where a Sheet is contained within a read only database, it may be displayed as a reference drawing by clicking the right mouse button with the cursor positioned over the CE and selecting Open Sheet from the displayed menu.


22

www.aveva.com


In a similar fashion, navigating to a Sheet with write access in the Draft Explorer, the Sheet may be displayed using the Working Sheet toolbar or the right mouse button and selecting Open Sheet from the displayed menu. The Sheet displayed in the below screen capture is a Draft Backing Sheet containing a single empty view.

The name of the Sheet will be displayed in the Working Sheet toolbar list and the currently selected Layer will appear in the Layers toolbar. The latter is illustrated below:

Each View will consist of a number of Layers; for the creation of Dimensions, Labels or 2D annotation for example – these will be described later in the Training. As found with the Design Hierarchy in PDMS Design, it is important to be correctly positioned in the Draft Hierarchy (and within a suitable Layer) when undertaking a task e.g. dimensioning. Where multiple Sheets remain open, the pull-down on the Working Sheet toolbar can be utilised to interchange between Sheets.


23

www.aveva.com


4.5 Manipulating the Sheet View

Both the keyboard and mouse (buttons) can be used to manipulate the view of the sheet. The commands associated with view manipulation are described in the sections that follow.

4.5.1 Left Mouse button

Clicking the left mouse button with the pointer over an element makes the element the Current Element (CE). The element may be a Design element i.e. part of the engineering item displayed, or a Draft element e.g. sheet outline, a label or a dimension. If slider controls are displayed, the mouse pointer can be used to pan the drawing display.

4.5.2 Middle Mouse Button

The middle button allows the user to increase and decrease the scale of the displayed view, as follows: Windowing in – clicking and holding the centre button/wheel allows an area to be defined to zoom into by dragging the mouse. Zooming in - Position the pointer at the point you want to become the centre of the view. Hold down the (shift) key and repeatedly click the middle button, as required. After each click, the display zooms in by a factor of 1.5, centred on the current pointer position. Alternatively, if your mouse has a wheel, rotating the wheel away from you will zoom in. Zooming out - Position the pointer at the point you want to become the centre of view. Repeatedly click the middle button, as required. After each click, the display zooms out by a factor of 1.5, centred on the current pointer position. Again, if your mouse has a wheel, rotating the wheel away from the user will zoom out.

4.5.3 Right Mouse Button

Clicking the right-hand button, when the pointer is in the main display, activates a shortcut menu.

Colour Settings Displays a „Colour Setting‟ sub-menu for selection.

3D view Displays the 3D view

For drawing production via the 3D View please refer to TM-1206 Drawing Production (Advanced).

4.5.4 Keyboard Commands

A number of keyboard commands exist that allow the user to zoom and pan in the graphical display. The commands described below work for most computers, however some laptop computers do not support this functionality. Zooming The Pg Up key can be used for zooming in. The Pg Dn key can be used for zooming out. Holding down the Ctrl key while zooming in or zooming out using the middle mouse button, doubles the zoom factor. The numeric keypad odd-numbered keys can be used for zooming (Keys 7 & 9 zoom in / Keys 1 & 3 zoom out). Panning Panning (moving the displayed area across the overall drawing) can be achieved using the commands below once the view has been suitably zoomed in. Use the up/down, left/right arrow keyboard to pan in the directions identified. Holding down the Ctrl key will increase the step size by a factor of 10. Holding down the Shift key will decrease the step size by a factor of 10. The even-numbered keys of the numeric keypad will also pan in the identified directions by half view width.

4.6 Resetting the Draft View

When the Draft Display has been zoomed or panned to a specific region it is useful to reset the display back to the full screen display. This can be done by using the Right hand Mouse Button and selecting Reset Limits as describe above or by using the Reset Limits Icon from the side of the Drawing display window.

4.7 Modify Mode

Used to modify the position or size of Draft Elements in the Main Display

4.8 Draft Grid

It is normal practice to position annotation on a grid so that elements are spaced evenly on the Drawing Sheet. To display the Display Grid, clicking on the Grid Icon. This is on the toolbar at the side of the Drawing display window. The grid is hidden by re-selecting the Grid Icon.

4.8.1 Changing the Grid Spacing

The Grid Spacing can be changed by selecting the Grid Icon using the right hand mouse button and selecting Spacing. The Grid Size and offset can be set as required.


26

www.aveva.com


4.8.2 Positioning Elements on a Grid (Snap)

Elements of a drawing can be positioned at grid points, by clicking on the SNAP to grid button. This feature will be discussed later in the course.

4.9 Saving and Restoring Views

Up to 4 views can be saved so that the designer can navigate quickly to a specific area of the Drawing. Clicking the right hand mouse button when positioned over the camera icon will save the view.

Views are restored by clicking the left hand mouse button when positioned over the camera icon.

4.10 Units

Units are assigned to values throughout PDMS e.g. distance, mass, temperature and pressure. The Current Session Units can be displayed: Select: Settings > Units...


27

www.aveva.com


Further to the definition of session units, a number of tasks inherent in Draft are suited to smaller units i.e. it is more appropriate to measure a dimension line termination in millimetres rather than metres. This is reflected in the forms presented to the User and will be observed throughout the training.

Intelligent text is independent of format gadgets. For example, if a position is referenced in a label, and the project units are metres, the output displayed for the position will be in metres.

Exercise 1 Draft Explorer & Viewing Controls

Using Chapter 3 as a guide, complete the following tasks:

1. Display the Draft and Design Explorers.

2. Navigate to and open Sheet /DRA/PRJ/TMP/PIPING/A0/S1.

Navigation to the identified sheet can be achieved by expanding the Draft Explorer hierarchy by selecting: Department (DEPT) /Project_Libraries Registry (REGI) REG /DRA/PRJ/TMP/PIPING Drawing (DRWG) DRWG /DRA/PRJ/TMP/PIPING/A0

Sheet (SHEE) SHEE /DRA/PRJ/TMP/PIPING/A0/S1

3. Familiarise yourself with Draft viewing controls (mouse buttons & Keyboard) to zoom and pan

across the Drawing Sheet.

4. Display the Draft Grid and alter the grid size to the following (Note that you may input 10 or 10mm with the same result) :

Do not close the Main Display window as it will be used in subsequent exercises.

CHAPTER 5


5 User Defaults

Draft makes extensive use of default settings which are normally configured and pre-defined by the Draft Administrator. On entry into Draft the default libraries are set. The Library Settings store the location of Symbols, Backing Sheets, Drawing Styles, etc...

5.1 AVEVA System Supplied Departments

There are four System Departments supplied with the product: Project_Libraries - contains sample sheets. Master_Libraries - containing standard backing sheets, symbol libraries etc... TT/Project_Libraries - contains sample sheets using True Type Fonts. TT/Master_Libraries - containing standard backing sheets, symbol libraries (etc…) using True Type Fonts.

Two sets of Libraries are supplied as it is not possible to mix the original Draft Fonts with Windows True Type Fonts on the same sheet. This also applies to referenced backing sheets, symbols etc.

5.2 Setting User Defaults (Training Set-Up)

The system settings defaults can be viewed and modified for the current session by the User. To display the User Defaults form: Select: Settings > User Defaults

Using the File option, Designers can load settings that have been pre-defined by the Draft Administrator.

User Defaults are only valid for the current Draft session.


30

www.aveva.com


5.3 Pre-Defined User Defaults (Training Set-Up)

The training course requires True Type System Defaults to be defined – as shown by the User Defaults form on the previous page. Further to selecting the File menu, the following options are available:

File > Load Pre-Defined Used to load the Draft System Defaults

File > Display Load Errors… Errors may occur if the Default Element does not exist in the

database. File > Display Load Errors… is used to view such errors.

The defaults for the Training have been pre-defined by an Administrator and are selected by: File > Load Pre-Defined From... Navigate to C:\AVEVA\Plant\Training12.1\pdmsui\dflts (or as located by Trainer). Select: dra-gen-system to populate the User Default form.

CHAPTER 6


6 The PDMS Draft Database Hierarchy

The previous Chapters have established a context to the Draft module and now Chapter 6 will introduce the formation of a Draft Hierarchy so that Drawings may be formed in an intelligent and organised manner. The creation of the Draft Hierarchy and defining the associated Attributes lends itself to a Worked Example. This Chapter will outline the creation of the „administrative‟ hierarchy elements: the Department and Registry. The outstanding hierarchy elements will be formed by continuing a (Trainer led) worked example though the proceeding Chapters. Ensuring that Draft > General… has been selected from the main Draft menu; create a Draft hierarchy through the completion of the following Sections and by following the lead of the Trainer.

6.1 Draft Database Hierarchy: Overview

The above diagram illustrates the Draft database hierarchy. As with all database elements, the owning elements can contain any number of legal members. The Department (DEPT), Registry (REGI) and Drawing (DRWG) elements can be viewed in the Draft Explorer, but cannot be displayed graphically. The principal element is the Drawing (DRWG) element. All elements positioned below the DRWG in the hierarchy are used to store the information required to completely define the drawing. A DRWG can contain one or more Sheet (SHEE) elements. A Sheet is the highest level element that can be displayed in the graphical view. A Sheet can own one or more VIEW elements. These Views are projections of parts of the design database. The attributes of a View element:

Define the viewing parameters (view direction, through point and scale

Define the size, position and orientation of the region on the sheet.

Refer to a draw list that contains a list of the DESIGN elements that are to be displayed in the VIEW picture.

WORLD

DEPT DEPT

REGI REGI

DRWG DRWG

SHEE SHEE


32

www.aveva.com


6.2 Draft Hierarchy: Department (DEPT)

Navigate to the World /* element using the Draft Explorer. To begin creating the Draft hierarchy select Create > Department from the main menu bar. The Create DEPT form will be displayed.

The User should enter a suitable name for the Department then click the OK button. For this example enter the following name: /DEPT-EQUIPMENT-AREA01

The Department Information form shows the name of the DEPT and gives an opportunity to automatically create a Registry and/or to set the attributes of the Department. Clicking on the Attributes button will display the Department Attributes form.

6.2.1 Department Attributes

The attributes set using this form are the default properties of the Sheets that will eventually be created in the branch below the Department. The attributes are cascaded down through the Registries and Drawings, but they can be changed at any level.

The attributes form is similar for both Department and Registry elements (discussed later in this chapter) with one exception that will be noted. The name of the current DEPT (or REGI) will be displayed in the name field of the form. Each of the main tabs will be considered in the sections that follow. Changes to the Department (or Registry) Attribute form are confirmed by selecting the Apply button. Clicking the Reset button on the form will reset all the attributes values back to the default settings. The form will remain open until the Dismiss button is selected.


33

www.aveva.com


6.2.1.1 Attributes Form: Size & Units Tab

This tab allows the User to define parameters associated with the drawing Sheet. The Width and Height values define the default drawing size that will be used upon creation of a drawing. The Backing Sheet selection is unset by default. Toggling the Radio button will set the default backing sheet reference to be used on drawing creation.

Unset The backing sheet reference is unset.

Reference Sets a default backing sheet from a list of available options.

Filename Sets a reference to a PDMS plot file. As per the example screen capture above, set the default Backing Sheet for the Department to a /TT/DRA/MAS/BACKS/MET/A0 sheet.

A Warning message may be displayed highlighting incompatible font settings. This is rectified on altering the Pen Font (Section 6.2.1.3)

The Units section of the tab sets the default units used for distance and bore size. Clicking on the Distance option list displays the following options:

Feet and Inches USA output of the form: 5‟-5 13/16”

Feet and Inches output of the form: 5‟5.13/16

Inches output of the form: 0.5 or 1.5 or 24.0

Inches USA output of the form: ½” or 1 1/2” or 24

Inches PDMS output of the form: 0.1/2 or 1.1/2 or 24

Millimetres distance in mm

Centimetres distance in cm

Metres distance in m Clicking on the Bore option list displays the following options:

Inches output of the form: 0.5 or 1.5 or 24.0

Inches USA output of the form: ½” or 1 1/2” or 24

Inches PDMS output of the form: 0.1/2 or 1.1/2 or 24

Millimetres distance in mm

Centimetres distance in cm

Metres distance in m Ensure that the Units options are set to: Millimetres. The Precision section of the tab sets the number of decimal places or fractions of an inch used as the default standard. For the purpose of the training, these values should be left as Default.


34

www.aveva.com


6.2.1.2 Attributes Form: Intelligent Text Tab

This tab allows the User to select the terms that will be displayed on the drawings for positional references. For Plant drawings the positional code words and output format will usually be toggled to ENU (East North and Up). For the purpose of the training, ensure the options remain as Default.

6.2.1.3 Pens Tab

This tab allows the User to set default pen colours, line styles, and fonts for the noted objects in the form. While styles and colours can be modified significantly, a range of prescribed styles is usually set by an Administrator. The default font is set to Standard Thin Upright which is a standard PDMS Font. To view the available standard fonts the User must click on the Select a PDMS Font option from the Font pull-down list. The PDMS Text Font Selector form will be displayed as shown: Three option lists allow the user to define the style, weight and slope of the text. Once a suitable selection has been made the User can confirm the font choice by selecting the OK button. Clicking the Cancel button will stop the selection procedure and dismiss the form.


35

www.aveva.com


The training requires a True Type font to be specified, the User must select the True Type font option from the Font option list as shown below:

The True Type Font Selection form will be displayed: The central selection grid will be populated with True Type fonts specified by the Administrator for the project. In recognition of the ability at 12.1 to utilise the Unicode format, select: Arial Unicode MS [5]

Square brackets indicate the default font.

Select: OK

Example Symbols, Labels and Backing Sheets are included in Draft Sample Project and are prefixed /TT. They can be found in /TT/Master_Libraries and /TT/Project_Libraries.

PDMS Draft and True Type Fonts cannot be mixed on the same Drawing Sheet. This includes any Symbols and Backing sheets that may be used.

6.2.1.4 Miscellaneous Tab

This tab allows the User to adjust the way a number of drawing details are formatted. In particular the terminator details used for dimensions, representation rules, date format, and the default text returned when intelligent text cannot be used.

!


36

www.aveva.com


If the Registry Attributes form is used, the date format cannot be set from the Miscellaneous Tab.

The Null text value is used when it is not possible to extract data from an attribute and the intelligent text system returns an error. Null Text may consist of up to 12 characters. Clicking on the Date Format option list allows the User to define the presentation of the date. Clicking on the Dimension Terminator and Leader Terminator option lists display the following options to the User:

Off no terminators shown on dimension / leader lines.

Arrows solid triangle arrows shown on dimension / leader lines.

Open Arrows outline triangle arrows shown on dimension / leader lines.

Dots solid dots shown on dimension / leader lines.

Open Dots outline dots shown on dimension / leader lines.

Narrow Darts acute two line arrow heads shown on dimension / leader lines.

Wide Darts obtuse two line arrow heads shown on dimension / leader lines.

Obliques oblique lines shown on dimension / leader lines.

Slashes slash lines shown on dimension / leader lines. For the purpose of the Training, set the Dimension Terminator to Arrows.

See Appendix A for example representations.

Clicking on the Ruleset Reference option list displays the available rule sets. Click on the Hatching Ruleset Ref option list displays the available hatching rules.

6.3 Draft Hierarchy: Registry (REGI)

If the Create Registry box was checked on the Create DEPT form, the Create REGI form will be automatically displayed at the end of the previous step. The Create REGI form can also be displayed by selecting: Create > Registry from the main menu bar. The User should enter a suitable name for the Registry then click the OK button. For this example enter the following name: /REGI-EQUIPMENT-AREA01 The Registry Information form will be displayed:

If a drawing is to be created immediately, check the Create Drawing box. The selection of Explicitly or From Template only applies if the Create Drawing box is checked. For the purpose of this training, uncheck the Create Drawing option as drawing creation is covered in the next chapter.

The different methods of creating drawings explicitly or from templates will be explained later in this manual.

Clicking on the Attributes button will display the Registry Attributes form. The function of the attributes form is very similar to that outlined for the Department Attributes form. Values selected during Registry creation will cascade to all other elements contained in the REGI.

Exercise 2 Creating the Draft Hierarchy (DEPT & REGI)

Using Chapter 6 as a guide, create the Department and Registry hierarchy elements for the Training Drawings outlined in Chapter 3 and as shown below: Equipment, Piping & Structural.

Draft Hierarchy:

In each instance ensure that the following attributes are set:

Backing Sheet Reference: /TT/DRA/MAS/BACKS/MET/A0

CHAPTER 7


7 Creating Drawings and Sheets

Building on the previous Chapter, Chapter 7 explores the creation of Drawings and Sheets. In the same vein as previously, this Chapter is presented as a Worked Example under the tutelage of the Trainer.

7.1 Creating Drawings and Sheets

Drawings can be created either explicitly, or by using a template. Both methods are available, regardless of whether the drawing is created by selecting the Create Drawing check box (on the Registry Information form), or by selecting Create > Drawing from the main menu. The Drawing created will own a Sheet, which will own at least one View. The View will own several Layers – these are discussed later. There may also be additional elements, such as Sheet Notes, which are used to store text and primitives for the 2D Drafting. The Drawing will also own a Library. Draft makes extensive use of libraries, which are set up by the System Administrator. Users can extract information from libraries but cannot alter the information contained within. Libraries are used to store, for example, symbols and Draw lists. The latter defining the contents of a View. Users will not access Libraries directly with the Application automatically accessing them as required.

7.1.1 Creating Drawings from a Template

If a drawing is created from a template, several elements will be created automatically. Navigate to the Registry /REGI-EQUIPMENT-AREA01 created earlier. Select: Create > Drawing > From Template from the Main Menu.

The Create New Drawing from Template form enables the User to select the source of the template and the drawing size.

At the top of the form, the Create Mode is set to Drawing from Template. If the form is used for creating a Sheet, the Create Mode is set to Sheet from Template, but otherwise the form is unchanged.


40

www.aveva.com


Using the From pull-down option list displays the available discipline registry that contains the drawing templates; as set up by the System Administrator. PDMS is supplied with example Registries and Drawing Templates. Using the From option list, select the Equipment Registry option. From the Template Drawing list select the A0 Equipment Drawing template. If required, a particular template can be set as the default template by selecting the Use as Default check box. If the Use Default Naming is checked, then the default naming convention will be used, which is DR1, DR2 etc. If this option is not checked then a name form will be displayed after clicking on the OK button. Uncheck the Use Default Naming check box. Click the OK button.

The Name form will be displayed, prompting the User to provide a name for the new Drawing. For this example enter the name: DRWG-TEMPLATE-EXAMPLE Click the OK button.

The drawing is displayed in the 2D graphical window automatically upon creation, and all associated hierarchy elements will have been created – displayed by the Draft Hierarchy.


41

www.aveva.com


7.1.2 Creating Drawings from a Default Template

A standard default template, as defined by the User Defaults form, can be used by selecting from the main menu: Create > Drawing > From Default Template Alternatively, click the icon in the Create New From Default Template toolbar menu.

If the Use Default Name is checked a default naming convention will be used.

A Drawing Sheet is created and will appear in the Drawing View together with the appropriate hierarchy elements.

7.1.3 Creating Drawings Explicitly

If a drawing is to be created explicitly, the create options contained within the main menu will be used to create the Drawing and associated elements, such as Sheets and Views. To create a Drawing explicitly, select from the main menu: Create > Drawing > Explicitly

The Create DRWG form will be displayed: For this example enter the name: /DRWG-EQUIPMENT-AREA01 Apply the form by clicking the OK button.

The Drawing Definition form is displayed: Enter the following information: Title Equipment Arrangement & Pump Detail Date 1 Apr 2020 (Current Date) Drawn By A.VEVA (Trainee‟s Name) To apply changes, click the Apply and Dismiss buttons

An actual drawing will not be displayed in the graphics window as it is the Sheet hierarchy element that holds Draft geometry. The Drawing hierarchy element (DRWG) serves an administrative purpose in a similar manner to Department or Registry hierarchy elements.


42

www.aveva.com


Selecting the Attributes button can be used to change the attributes of the Drawing. The layout and function is similar to the Department Attribute Form described previously.

7.1.4 Creating Drawing Sheets Explicitly

To create a Sheet explicitly, select from the main menu: Create > Sheet > Explicitly

The Create SHEE form will be displayed: Enter the name: /DRWG-EQUIPMENT-AREA01/S1 Apply the form by clicking the OK button The Sheet Definition form is displayed:

Enter the following information: Title: AVEVA Draft Training Backing Sheet Reference: /TT/DRA/MAS/BACKS/MET/A0

To apply changes, click the Apply and Dismiss buttons

Backing Sheet Reference should be pre-defined due to the setting at Department and Registry elements.

Note the LIBY elements owned by the DRWG element and, unlike the Template created drawings, the lack of a View.

Do not delete, rename or modify any LIBY elements or any of the owning members. They are controlled by the application.


43

www.aveva.com


Exercise 3 Create a Drawing Explicitly

Using Chapter 7 as a guide, create Drawings and Sheets explicitly beneath the appropriate Discipline department as follows:

DRWG-PIPING-AREA01 Title Piping Arrangement Date 1 Apr 2020 (Current Date) Drawn By A.VEVA (Trainee‟s Name)

/DRWG-PIPING-AREA01/S1 Title: AVEVA Draft Training Backing Sheet Reference: /TT/DRA/MAS/BACKS/MET/A0

DRWG-STRUCTURAL-AREA01 Title Structural Arrangement & Joint Detail Date 1 Apr 2020 (Current Date) Drawn By A.VEVA (Trainee‟s Name)

/DRWG-STRUCTURAL-AREA01/S1 Title: AVEVA Draft Training Backing Sheet Reference: /TT/DRA/MAS/BACKS/MET/A0

When created note the LIBY elements owned by the DRWG element.

Do not delete, rename or modify any LIBY elements or any of the owning members. They are controlled by the application.

CHAPTER 8


8 Creation and Modification of Views

Chapter 8 will explain the creation and modification of views. Using the Drawings created in the previous Chapter, the training will continue as a Worked Example supplemented by the theory associated with the task.

8.1 Creating Views with Pre-Defined Frames

As found with the creation of a Drawing from Template, the arrangement of Views can be defined using Predefined View Configurations within Draft. Selecting Create > View > Predefined Frame will display the View Configuration form. This form allows the User to create a number of views for the current sheet based on the pre-defined configurations available. The View directions for the views can be selected from the pull-down option lists adjacent to the selected view option. The View spacing value is the distance between the limits of the views.

A typical sheet layout using predefined views is shown below.


46

www.aveva.com


8.2 Pre-Defined View: Worked Example (Equipment Detail)

Create a new drawing explicitly beneath the previously created Registry: REGI-EQUIPMEN-AREA01 with the following Drawing Definition:

Name: DRWG-EQUIPMENT_DETAIL-AREA01 Title Equipment C1101: Nozzle Detail Date 1 Apr 2020 (Current Date) Drawn By A.VEVA (Trainee‟s Name)

Set the Backing Sheet to TT/DRA/MAS/BACKS/MET/A2, to create an A2 sheet for population and set the Sheet Title as AVEVA Draft Training Create 4 views with predefined frames, using the option Create > View > Predefined Frame. The View Direction in each view is set to Down. The Drawing will be displayed as follows:

8.3 User-Defined Views

Where the volume or limits of design items are unknown, User-Defined Views may be used to illustrate individual items or groups of items in the design model. The size of the bounding frame is independent of the View contents and the View scale can be automatically set to fit the design elements to the available View frame area. A View is owned by a SHEE element. Before creation of a View, ensure that the correct SHEE is the Current Element. Navigate to Sheet: SHEE DRWG-EQUIPMENT-AREA01/S1 and ensure it is the Working Sheet. From the main menu select: Create > View > User-Defined… to display the Create VIEW form: In this instance the default View name is acceptable. Select OK to accept the default name. The User-Defined View form will be displayed:


47

www.aveva.com


8.3.1 User-Defined View Form: Frame Menu

The Frame menu accessed via the User-Defined View form enables the User you to switch the View Frame on or off, to control the size of the frame, its position on the Sheet and its alignment relative to any other View that may exist within the Sheet bounds. The menu options are discussed in further detail below.

Size This option has a sub-menu that allows the User to set the size of the view frame either by the Cursor or Explicitly.

Cursor: displays the Point Construction Option Form. This enables the opposing corners of the View Frame to be selected graphically.

Selecting the 2D Cursor Hit option from the option list allows the User to re-size the view window using a diagonal window.

Explicit: displays the Explicit Frame Size form. This resizes the frame by defining the size in terms of sheet co-ordinates or proportions.


48

www.aveva.com


Copy Size This option has a sub-menu that allows the User to copy the Width and/or Height of a second View via cursor selection.

Position This option has a sub-menu that allows the User to position the frame by:

Cursor: enables the User to use the cursor to move the View Frame by nominating a point in the View. A further sub-menu allows the User to define how the cursor nominated point is positioned. Explicit: displays the Explicit Frame Position form. This enables the User to position the View Frame by defining its Sheet position in terms of sheet co-ordinates or proportions.

Align This option has a sub-menu that allows the User to align a specified axis or edge of the current View with the same axis or edge of an existing View on the Sheet via cursor selection.

Centre Vert: prompts the User to identify the central vertical alignment of a View to be used to align the current View. Centre Horiz: prompts the User to identify the central horizontal alignment of a View to be used to align the current View. Top: prompts the User to identify the top edge of a View to align the current View. Bottom: prompts the User to identify the bottom edge of a View to be used to align the current View. Left: prompts the User to identify the left edge of a View to be used to align the current View. Right: prompts the User to identify the right edge a view whose right edge is to be used to align the current view. The position of the current view will then change to align the views right edges.

8.3.2 User-Defined View Form: View Menu

The View menu on the User-Defined View form enables the User to toggle the display of the view on or off, centre the View via Design co-ordinates and offset the Design element graphics with respect to the centre of the view. The menu options are discussed in further detail below.

Centre This option has a sub-menu which allows the designer to select the centre of interest of the view. Identify: prompts the User to identify a design element to be the centre of interest of the View. Cursor: displays the Point Construction Option Form and prompts the User to select a point with the cursor to become the centre of interest.

By Cursor: displays the Point Construction Option Form and prompts the User to select a base point and displacement with the cursor to move the centre of interest of the View. Explicit: displays the User Defined Centre Position form enabling the User to enter co-ordinates for the centre of the View.

Offset Displays the Design Graphics Offset Form. The form enables the User to position the centre of the View contents relative to the view centre.

8.3.3 User-Defined View Form: Graphics Menu

The Graphics menu on the User-Defined View form enables the User to create and modify a Drawlist as well as setting the Drawlist Reference for the View. A Drawlist holds a list of Design elements that determine what will be displayed in the View. The Drawlist is independent of the Views. A Sheet may contain several Views that refer to the same Drawlist, or several views that refer to different Drawlists. Drawlists (IDLI elements) are stored in Drawlist Libraries (DLLB elements). When a Drawing is created, a Library containing a default Drawlist Library is automatically created and may be used as the Drawlist for any Views created on Sheets owned by that Drawing. Specific Drawlists for specific Views may also be created and stored in the default Drawlist Library, or in another Drawlist Library located elsewhere in the project subject to the set-up instigated by the Draft Administrator. The menu options are discussed in further detail below.

Drawlist Selecting Graphics > Drawlist will display the Drawlist Management form:

Drawlist Library: list displaying the available Drawlist Libraries.


50

www.aveva.com


Drawlists: Scrollable list of all the Drawlists available within the selected Drawlist Library

Create Creates a new empty drawlist Create Copy Creates a copy of the selected drawlist Delete Deletes the current selected drawlist Clean Up Removes any drawlist members with Null or Bad references

Reference List Members: Displays Design Members of the current MDB.

: If Drawlists is selected from the scrollable list, the available Drawlists will be displayed.

The Lists... button allows lists to be selected where previously defined. If there are no Lists defined, or a list is required, clicking the button will display the List/Collection form. Having defined a new List, clicking the Update button will display all defined Lists in the scrollable list for selection. Drawlist Members window: displays the Design elements or Drawlists that have been selected to be members of the current Drawlist.

Items are added to the Drawlist by selecting them from the Reference Members List, or a List / Collection name from the scrollable list, and clicking the Add button. This creates an Add Element (ADDE) in the Drawlist Members window. Specific items may also be removed from the Drawlist by selecting them in the Reference Members List, or a List/Collection name from the scrollable list, and clicking the Remove button. This creates a Remove Element (REME) in the Drawlist Members window. In the example above, all equipment except /E1301 is required to be displayed in the View. Rather than adding each piece of equipment separately, the zone /ZONE-EQUIPMENT-AREA01 may be added and the specific piece of equipment /E1301 subsequently removed from the Drawlist.

Delete Entry & Delete All: Delete the current highlighted entry from the Drawlist or all Drawlist members respectively.

Volume Defined: Enables the addition of all elements that are positioned wholly within a defined volume. Limits: Clicking the button will display the Drawlist Limits form. The limits are set by entering appropriate co-ordinates for opposing corners of the limits box.


51

www.aveva.com


Drawlist Ref Selecting Graphics > Drawlist Ref… will display the Drawlist Reference form.

This form enables the User to reference the current View to a Drawlist thereby defining the Drawlist Members to be displayed in the view.

A view may only reference one Drawlist.

The Options scrollable list allows the Drawlist of the owning Sheet, or the owning Drawing, to be used.

The Drawlist Library scrollable list allows the User to choose from a list of Drawlist Libraries, as set up by the Draft Administrator. The „Drawing‟ selection refers to the Drawlist Library created automatically when the views owning Drawing was created. The Drawlist Contents window displays the contents of the selected Drawlist when the Display button is clicked. This allows the User to check the contents of the Drawlist selected. The Modify button displays the Drawlist Management form enabling the user to modify or create a new Drawlist as described previously.

8.3.4 User-Defined View Form: General Tab

The General Tab of the User-Defined View form allows the User to define representation styles, View directions and the Title associated with each View. The various option lists and functions are described below.

Title This field allows the User to enter a Title for the view being created e.g. Plan North, or Western Elevation.

To limit the amount of free text used it is possible to use Intelligent Text to reference a View Title. Intelligent Text is discussed later in the Training.

View Type A View type must be selected. The View Type option list displays the following options:

Modelled Wireline: produces slightly greater realism by blending the intersection of primitives, but without incurring the computational overheads of removing hidden lines.

Wireline: produces a conventional wireline picture showing all element and P-Points. This option is the quickest to generate the view graphics. Wireline Hidden Line: produces an image where hidden lines are removed within individual significant elements (EQUI, SUBS etc...), but not from items hidden behind them.


52

www.aveva.com


Local Hidden Line: produces a picture where all hidden lines are removed from equipment elements. Where two or more equipment elements overlap, the overlapping elements are shown in Wireline. Global Hidden Line: produces a picture where all hidden lines are removed. Universal Hidden Line: produces an image where all hidden lines are removed (as in Global Hidden Line), but in addition intersection lines between significant elements (e.g. EQUI and STRU, SUBS and BRAN) are generated.

For further representation examples refer to Appendix A.

Section Mode A section mode must be selected. The Section Mode option list displays the following options:

Standard: this option sections all Design elements where appropriate. Omit Fractional Pipe Components: this option removes any partial pipe components from the display, where the P0 is outside the front and back sectioning planes. All lengths of implied tube that are outside the front and back sectioning planes will be removed from the drawlist.

Style The Style option list shows the available Representation Ruleset (RRST) elements that are used to control the display representation of the different types of Design elements within the View e.g. element dependant line weights andcolour. Representation Rulesets are created by the Draft Administrator.

Hatching Rules The Hatching Rules option list displays the available Hatching Rulesets that are used to control the hatching of different types of Design elements that may be cut when a section is applied. Hatching Rulesets are created by the Draft Administrator.

Change Rules The Change Rules option list shows the available Change Rulesets that are used to control the appearance of changed Design elements and annotation on subsequent updates of the drawing.

For the use of Change Rulesets please refer to TM-1206 Drawing Production (Advanced).

Direction The required View direction may be selected from an option list of pre-defined directions. Alternatively, a View direction may be typed into the text box, e.g. N 45 E. The Derived button will prompt the User to identify a design element in the Graphics area for setting the View direction.


53

www.aveva.com


8.3.5 User-Defined View Form: Scale Tab

The Scale Tab allows Users to set a scale type (metric or imperial), apply a specific scale to the Drawlist, or Auto Scale the Drawlist before applying the nearest standard scale. Three types of scale are available from the options list; Metric, Architectural, and Engineering.

Metric: this option allows the User to apply a unit-less scale to the Drawlist e.g. 1/10, 1/100, and 1/500

Architectural: this is an imperial unit option that expresses scales in terms of inches to the foot and is generally used for buildings and structures.

Engineering: this is an imperial unit option that expresses scales in terms of inches to the tens of feet and is generally used where larger scales are required.

Once the type of scale has been set the User can select a scale from the option list to apply to the Drawlist. Alternatively, the user can make use of the Auto Scale and Nearest buttons to set a suitable scale based on the contents of the Drawlist and the size of the drawing selected.

Auto Scale Auto Scale sets the view scale such that all of the design elements in the Drawlist will fit to the view frame. The actual scale will be displayed in the Scale text box. The Auto Scale operation also sets the through point to the Site coordinates corresponding to the centre of interest of the view. It is unlikely that the scale provided will conform to that of a recognised standard.

Nearest The Nearest button selects the nearest available standard scale, as defined by the Draft Administrator, and sets it. The standard scales can also be selected from the scrollable list next to the Nearest button.

For Draft to calculate a scale, the Drawlist must contain elements.

8.3.6 User-Defined View Form: Intelligent Text Tab

This tab contains the same parameters as those contained in the Department Attributes form. Please refer to section 6.2.1.2 of the guide for further information.

8.3.7 User-Defined View Form: Attributes Button

Clicking the Attributes button on the User-Defined View form displays the User Defined View Attributes form.


54

www.aveva.com


The following attributes of the View can be modified from this form:

Graphics Angle The field controls the angle of the design graphics within the View. A positive angle results in an anti-clockwise rotation. The View direction remains the same.

View Orientation The field controls the orientation of the View and the contents. The selectable directions correspond to the direction of the „top‟ of the view region relative to the top of the screen, e.g. selection of Right will cause the View and the contents to be rotated through 90 degrees.

Arc Tolerance The field controls the appearance of arcs within the View. Arcs are drawn as facetted approximations of a true „smooth‟ arc; this field controls the difference between the „true‟ and the „facetted‟ representation. The representation is set in units of hundredths of a millimetre on the drawing (default value 15). The actual value used by DRAFT depends on the scale of the VIEW. The lowest value that it may be changed to is 1. Although lower values will give a better representation, the time required to display the graphics is increased.

Perspective Perspective can be used to give a perspective projection, the field value being related to the view angle. The default value of 0 results in a parallel projection.

Gapping Controls the gap (in mm) inserted in view lines crossed by other lines such as centrelines.

Note Line This option controls the appearance of the view frame (assuming it is visible). The value set will also be cascaded down to any Layers subsequently created. The Note line Pen may be a standard pen, or a user-defined pen set-up by the Draft Administrator

The colour assigned to the Note Line pen can be selected from the pull down menu. Alternatively, by clicking on the Pick button, a colour can be selected from the palette displayed.

The line style and thickness can be selected from the appropriate pull down menus.

www.aveva.com


8.5 Limits-Defined View

Limits-Defined Views are used to draw the contents of a specified volume of the model. The Limits are defined in project co-ordinates, and are represented by the size of the View frame at the selected scale. The View frame can include match lines with text showing the co-ordinates of the View limits.

8.5.1 Creating Limits-Defined View

A View is owned by a SHEE element, so before creation of a view ensure that the correct SHEE element is selected. To initiate View creation, the User must select: Create > View > Limits Defined On accepting the View Name form, where the name is derived from the owning element, the Limits-Defined View form is displayed: Although similar in appearance to the User-Defined View form, there are some notable differences. An additional Limits tab and menu allows the User to set the limits of the View. The Matchlines check box has a toggle function determining whether or not matchlines will be displayed and the scale options are also different in the Limits-Defined View form.

8.5.2 Limits-Defined View Form: Limits Menu

The Limits menu on the Limits-Defined View form displays the following sub menus:

From Element

From Design Point

From Pline Any End

From Pline Prop’n

From 3D Cursor

Drawlist Members The limits can be set using the sub menus from under the above options, by using the cursor and identifying the pick points as selected. The limits can also be copied from another view using the Copy From View option, or calculated by the application using the Drawlist Members option.


62

www.aveva.com


8.5.3 Limits-Defined View Form: Limits Tab

The limits can be set explicitly using project co-ordinates, which will define the area of the model to be displayed in the view. Checking the box next to the co-ordinate value, will create a section plane at that position.

Section planes are considered in Chapter 12.

8.5.4 Limits-Defined View Form: Scale Tab

The scale of the view can be automatically calculated by clicking the following:

Set Scale: calculates the scale of the view based on the View Frame Limits and the Limits of the view. The value in the % gadget is used when using this option. The scale displayed is actual scale value calculated x %.

Nearest – it is unlikely that Set Scale will produce a standard scale for the view. Clicking the Nearest button will select the nearest available standard scale, based on the metric, architectural or engineering scale option selected, and set the view scale. The standard scales can also be selected from the scrollable list next to the Nearest button.

8.5.5 Limits-Defined View Form: Matchlines Checkbox

If the Matchlines box is checked and the Update Graphical Aids button is clicked, matchlines will be displayed around the limits of the view with the respective co-ordinates.

8.5.6 Limits-Defined View Form - Update Design on Apply

8.6 Limits-Defined View: Worked Example (Equipment Detail)

The following worked example outlines the key processes involved in creating a limit defined view. It builds on the hierarchy created in earlier and involves the manipulation of a previously created pre-defined view. Navigate to the Sheet: DRWG-EQUIPMENT_DETAIL-AREA01/S1 and select the View …/V1 Select Modify > View > Limits-defined… from the main menu. The Limits-Defined View form will be displayed.

8.6.1 Populating the Drawlist

Select Graphics > Drawlist from the Graphics menu of the Limits-Defined View form. The Drawlist Management form will be displayed. From the Reference List Members area of the form, navigate to SITE-EQUIPMENT-AREA01 and select ZONE-EQUIPMENT-AREA01 Select equipment /C1101 and then click the Add button before dismissing the form .

8.6.2 Setting the View Limits

The limits will be initially calculated based on the Drawlist Items. Select Limits > Drawlist Members from the Limits-Defined View form. The Limits will be set based on the view content and could be changed and aligned with other Views as appropriate.

Using the Scale tab on the Limits-Defined View Form, set the Scale to 1/20.

Navigating to the Limits Tab displays the co-ordinates that represent the section planes that enclose the Drawlist Members. Modify the elevation of the View limits to the elevations shown below, ensuring the box next to each elevation is checked.

View 1: Elevation from Up 100300 to Up 106975

Ensure the View is given an appropriate title to identify the view limits:

8.7 Detail View

A Detail View is an enlarged view of a specified part of another view. The Detail View may be placed on the same sheet as the „master‟ view, or on a different sheet. The scale of the Detail View may be adjusted to suit the requirements for which the view was created. Detail Views are valuable in adding clarity to a Drawing and can be utilised alongside Limits-Defined and User-Defined Views.

8.7.1 Creating a Detail View

Selecting Create > View > Detail prompts the user to select an existing view to become the Master View, i.e. the view from which the Detail View will be taken, and then displays the Create Detail View form:

The Master View reference at the top the form shows the name of the Master View. The Reference text box shows the reference that will be used for the Detail View, e.g. View_01. The default for this entry is 01; however, it may be modified to suit any numbering scheme. The text must be incremented manually if subsequent Detail Views are created. The Detail Sheet text box enables the User to specify the location of the Detail View. The default of Local will create the Detail View on the same sheet as the Master View. To specify another sheet for the Detail View, navigate to an existing sheet in the Draft Explorer and click the CE button. The sheet name will then be displayed in the textbox. Clicking the Display button will display the sheet that will contain the Detail View. The Goto >> and Return << buttons navigate between the sheets in the Draft Explorer containing the Detail View and Master View respectively.

The Detail Shape pull-down enables the User to determine the 2D primitive and definition options that will be used during detail note creation, i.e. the shape that will appear on the Master view to define the Detail View. The options are:

Circular detail note

Circular detail note defined by bounding square

Square detail note

Elliptical detail note defined by a bounding rectangle

Rectangular detail note


68

www.aveva.com


The Volume Defined Drawlist checkbox enables the User to determine how the Drawlist for the Detail View will be created. If it is unchecked, the Detail View Drawlist will be the same as the Master View, if it is located on the same sheet, or a copy of the Master View Drawlist if it is located on a separate sheet. If it is checked, the Detail View Drawlist is rebuilt from the volume of the Detail View. The Local Note textbox enables the user to enter the text that will be displayed locally to the detail call-out on the Master View. This may be intelligent or un-intelligent text. Clicking the Examples button displays the Example Text form that contains alternative intelligent text strings that may be used for the Local Note. The Detail Note textbox enables the user to enter the text that will be displayed with the Detail View, whether on the same sheet as the Master View or on a separate sheet. Again, this may be intelligent or un-intelligent text and further examples may be obtained by clicking the Examples button to display the Example Text form.

The default text and example texts may be set for both Local Notes and Detail Notes by the DRAFT Administrator. If no example texts are set the Examples… buttons will be greyed out and unavailable for use.

Once all the required settings on the Create Detail View form are made, clicking the Apply button will display the Point Construction Option Form. The Point Construction Option Form prompts the User to identify a Detail Centre and Radius within the Current View by selecting two points.


69

www.aveva.com


On selecting the defined shape, the Point Construction Option Form is updated to prompt the User to select a Position for the Detail Text local to the Current View. On selecting a point for the Local Note, the Point Construction Option Form updates to prompt the User to select a position within the Sheet to centre the new Detail View frame. If a different sheet for the Detail View than the one containing the Master View is selected, that sheet will be displayed to enable positioning of the view frame. On selecting a position for the Detail View, the Detail View Scale form is presented. The form allows the User to set an appropriate scale – the Test Scale button enables the User to test the chosen scale. The Detail View frame may also be repositioned at this point by selecting one of the positional options from the pull-down and clicking the Position Frame button.

On clicking OK, the User is presented with a Confirmation message whereby the User is given an option to further modify the View. Clicking the Yes button displays the Limits Defined View form to allow further View modification.

A Detail View is a normal view and can be annotated and dimensioned as required.

Exercise 9 Detail View Creation (Equipment Arrangement)

Using Section 8.7 as a guide, create a Detail View for Equipment Item C1101 using Drawing Sheet: DRWG-EQUIPMENT-AREA01/S1. When the Point Construction Option form appears, use the 2D Cursor hit method to position the Detail View as shown below. Ensure the Detail View has a Type: Global Hidden Line.

Looking at the Draft Hierarchy, the ordering of views can be altered using Modify > Hierarchy > Reorder…

CHAPTER 9


9 Dimensioning

Chapter 9 describes the use of Dimensioning in Draft. Dimensions are calculated directly from the design model. The User can control the format, content and appearance of the dimensions. The Administrator can define suitable project defaults. Direct reference to the design data means that the annotation always reflects the current state of the design model, with a simple update annotation operation. Once the dimensions have been created, the position and orientation of dimensions can be adjusted graphically.

9.1 Dimension Hierarchy

Dimensioning elements are created under Layers owned by Views, as shown in the following diagram. Different types of dimension are created on different layers. All these elements will be created automatically as the View is dimensioned.

9.2 Dimension Types

There are four generic dimension types available in Draft, namely, Linear, Angular, Radial, and Pitch Circle Diameter. These allow intelligent dimensions to be created to dimensioning standards.

SHEE

VIEW VIEW

LAYE

RDIM ADIM PDIM LDIM

DPPT DPPT

100 J200

LINEAR DIMENSION

ANGULAR DIMENSION

RADIAL DIMENSION

PITCH CIRCLE DIAMETER


72

www.aveva.com


9.3 Linear Dimensions

Linear dimension elements are created under Layers owned by Views. Linear dimensions can contain the following dimension points: DPOI: allows dimension to/from any given 3D positions DPPT: the dimension point is defined by a p-point of the design element DPBA: allows you to dimension to/from before or after a Design element (in the Dimension direction). The dimension element and the dimensions are automatically created by the application.

The diagram illustrates the following features that comprise a linear dimension:

Dimension Point LDIM (linear dimension) must contain at least 2 dimension points (DPPT).

Projection Line a projection line will be drawn from each dimension point in a direction specified by the user. A projection line can have intelligent text.

Dimension Line a dimension line will be drawn between all projection lines, these have terminators.

Dimension Direction this direction is defined by the user.

Offset the distance of the dimension line from the dimension point.

Clearance distance of start of projection line from dimension point.

Overshoot distance of end of projection line from dimension line.

The values shown in the dimension text are taken directly from the 3D Design model. If the elements associated with the dimension points are moved in DESIGN, the dimension can be updated automatically by selecting Graphics > Update > Annotation.

9.3.1 Creating Linear Dimensions

Projection Line Text: Can be selected from the pull down

Projection Line Text Angle: Allows the text to be orientated from the projection line Click on the Derived button and the User will be prompted to identify a design element to derive the direction of the dimension. Click OK and the following form will be displayed. This form is used to create the points that define the Dimensions and form the link with the 3D Model element. The list on the left of the form sets how Dimension Points are created. The User must ensure that the correct option is selected in the list e.g. dimensioning to a p-point, the deign item or before/after a design element The default is that the Create button must be used for each point,

but you can click on the symbol (to the right of the Create button) so the adjacent checkbox displays a tick. This allows several points to be reated of the same type.

Note: The symbol must be off if you want to create Dimension Points in different ways, or if you want to use the 3D Pos, Cursor or Match line positioning options. The User is required to click on Create and identify the elements to be dimensioned. This can be done in the 2D View by holding down the left mouse button (the pointer shape changes to a square), moving the pointer over the item and releasing the button. Note: When the pointer passes over a suitable item, that element is highlighted and the name is displayed in the Status Bar. Once the dimension string is completed, press the Escape key on the keyboard. The dimension and associated dimension points are then created and can be seen in the Draft Hierarchy below the Dims LAYE of the View.

9.3.2 Deleting dimension points

A dimension point can be deleted by identification in the 2D view to make it the CE. The User either selects Delete from the right-click context menu over the DPPT (Dimension Point) element in the Draft Explorer or select Delete > CE from the main menu. A confirmation message is prompted on deletion, click the Yes button to confirm the action.

9.5 Intelligent Text

It is very important that the use of “Free Text” is minimised in Draft Drawings - wherever possible, text should be derived from the Database. In the previous example, the Equipment Name has been automatically set from the database. Typically any attribute can be placed on the drawing by preceding it with a # symbol, for example: #NAME #EQUI #POS With a slash preceding PDMS element names, it is often necessary to remove this slash on naming elements in Draft. This is possible using Intelligent Text: #EQUI(C2:) i.e. Name starting at Character 2.


80

www.aveva.com


Navigate to the View: DRWG-EQUIPMENT-AREA01/S1/V1 and to the Dimension Point on equipment C1101 created previously. Select: Modify > Dimension > Projection Text. The Text is set to ~C #EQUI(C2:). This annotation will draw a Centre Line symbol followed by the name of the element (starting at character 2) that the dimension is attached to. In this case an equipment item.

Select the Intelligent Texts button. This displays an index of commonly used references. From the displayed intelligent text references select #POSE followed by the Append and Dismiss buttons. The Enter key is used to place the new text on the next line down. Select the Apply button on the Projection Text form then Dismiss the form.

9.7 Angular dimensions

Further to the previous Sections, this section will explore the use of Angular Dimensions.

9.7.1 Creating Angular Dimensions

Ensuring that the correct dimension layer is the CE, if the User selects Create > Dimension > Dimension Angular from the main toolbar, the following form is displayed. The Create Angular Dimension form allows the User to determine the dimension type, direction and termination together with the ability to turn Projection Line Text on and off. On selecting OK, Draft will prompt to identify the item that the angular dimension is to be attached to (i.e. Centre for dimension). For example DISH 1 of EQUIP C1101, as shown below.

Using the selection Item and Create, the following points are chosen by the User:

The dimension will have its origin that is the point from which the angular dimension directions will radiate, at the origin of the element picked. The Linear/Angular Dimensions form is then displayed. This is the same

form as displayed for Linear Dimensions, and it is used in the same way. Switch on the symbol, and click on Create. The User will be prompted to pick the items to be dimensioned. The Nozzles are identified in the order shown in the above illustration - selection is clockwise, because the setting is Clockwise in the Create Angular Dimension form. On completion, the User should click on the background or press the Escape key. The dimension will be drawn as shown below:


86

www.aveva.com


9.7.2 Modifying angular dimensions graphically

Modifying angular dimensions graphically is limited to changing the offset and standout distances. The offset of the dimension on C1101, so that the projection lines pass through the nozzles in question, is done as before in Modify Mode.

The dimension line is dragged to the required position and then fixed with a Click on the background or by pressing the Escape key. The dimension will then be drawn like this: Remember to exit Modify mode.

9.8 Radial dimensions

Further to the previous Sections, this section will explore the use of Radial Dimensions.

9.8.1 Creating Radial Dimensions

Radial dimensions are created in a similar manner. The Dimension Toolbar is displayed by: Selecting Create > Dimension > Dimension Toolbar from the main menu bar and the following form is displayed. Select the Radial tab. Check that On Item (not On Point) is displayed. This is done by right-

clicking on the symbol. A tick mark is placed against the current setting. To change the setting left click on the desired option.

Select the required radius style. Refer to the Tooltips for the description of the available Radial dimensions.

Once the required dimension style is selected a user prompt will be displayed:

‘Identify item to be dimensioned’.

The dimensions will be created as shown in the following diagram.


87

www.aveva.com


After the dimension is created the Radial Dimension form is displayed. This form can be used to modify the dimension.

The User can also modify Radial Dimensions graphically in a similar way to modifying other dimension types.

Exercise 13 Creating Radial & Angular Dimensions

Navigate to the Equipment Detail Drawing created earlier (DRWG-EQUIPMENT_DETAIL-AREA01) and dimension the drawing, using linear, angular and radial dimensions on all 4 views.

Ensure that the correct layer is selected when dimensioning the views.

CHAPTER 10


10 Labelling

Labels are a form of drawing annotation, comprising text and/or graphics, associated with Design items. There are two types of Label, General Labels (GLAB) and Symbolic Labels (SLAB). The characteristics of these are as follows:

General Labels consist of text derived from the design model.

Symbolic labels based on a template often containing a symbol and intelligent text.

10.1 Labelling hierarchy

Labels (GLAB and SLAB) elements are owned by Layers. Whenever a view is created a number of layers are created. Additional layers can be created as required. A GLAB has a DDNM attribute which will contain the design element being referenced. A SLAB has a DDNM attribute and a TMRF attribute which references a SYTM.

10.2 Creating / Modifying Layers

If additional layers are required the User must select Create > Layer from the main menu and the Create LAYE form will be displayed. A default name will be given and the User must select the correct Layer Type.

The Layer definition can be modified by selecting Modify > Layer > Definition to display the Layer Definitions form.

Selecting the Layer to modify from the displayed layers; the Name, Purpose and visibility can all be modified.

In the instance of selecting the Attributes button, the LAB Layer Attributes form is displayed.

On the Text tab, the text height and definition can be modified.

The Tab changes depending on the purpose of the label selected.

10.3 Creating Labels

Selecting Create > Label > General/Symbolic from the main bar menu will display the Labels form. Both General and Symbolic labels can be created from this form. The workflow associated with each type of label is outlined in the sections that follow.

10.3.1 Creating General Labels

The creation of General Labels is initiated by selecting the General Labels Tab on the Labels form. Firstly, the User selects the Attach to options list. There are a number of menus and types to select from. The option selected will then be the only element type for the current creation that a label can be attached to. The Create New button will create a new GLAB that will be connected to the element type selected in the Attached to options list. The Create Copy button will create a new GLAB, and the User will be prompted to identify an existing GLAB. If the element being identified has p-points, the p-point number to be attached to on the element can be entered in the PPOINT box, or clicking on Cursor, will prompt the User to identify a p-point.


91

www.aveva.com


If the element being identified has p-lines, the p-line name to be attached to on the element can be entered in the PLINE box, or clicking on Cursor, will prompt the User to identify a p-line. The distance along the section is defined as a proportion of the length, and any value less than 1 can be entered in the Proportion field. The rotation of the label can be specified. Blanking can either be on or off, by placing a check mark in the Blanking box. The margin around the blanking can also be specified. The Attributes pull down has the following options:

Text Settings:

Displays the Label Text Attributes form, where the text attributes can be modified.

Text Contents:

By default the contents of the label are set to the name of the labelled element. The contents can be changed via the displayed Modify Text form. The position, alignment and justification can all be modified from this form. The text contents can be modified to be an intelligent text by either typing directly in the form or alternatively, clicking on the Intelligent Texts button will open a form with examples of intelligent text that may be used.

Frame:

Displays the Label Frame Attributes form. The frame visibility can be turned off. The Label frame pen colour and style can be modified along with clearance and angle settings.

Leader Line:

displays the Label Leader Attributes form. A number of options are available for inserting bends and gaps in the leader line. The Connection option allows the User to define the position of the leader line to the GLAB. The Attachment option allows the User to position the leader line away from the referenced design element.


92

www.aveva.com


10.3.2 Positioning General Labels using Modify Mode

Modify mode is used to modify Dimensions, Labels and 2D Geometry by graphical interaction. There are many other non-geometrical modifications, such as changing the appearance of the text and line styles that can only be carried out using the main menu Modify option.

10.3.2.1 Entering and Exiting Modify Mode

To enter Modify mode the User must click on the icon in the Drawing Display Window toolbar. Draft will exit from Modify mode when the Modify Mode button is selected again, a new Sheet or Library is loaded, or the design, model, picture or annotation is updated. While in Modify mode the User can control the view by zooming and panning as normal. The label for modification is selected by left-clicking on it. It is then displayed in the current highlight colour. When you select the label, several hotspots are displayed. Initially the Attachment and Connection point hotspots for the leader line (if leader lines have been selected for the label) are on a single point, adjacent to the label. The arrangement of the hotspots becomes apparent when the label is moved from its initial position. The following illustration shows the label moved upwards and to the right:

The position of the label can be moved by left-clicking and dragging its outline. By left-clicking and dragging a hotspot the user can modify the angle of the label or the geometry of the leader line. Once an item or hotspot has been selected in Modify mode, the Modify Mode shortcut menu can be displayed by clicking the right-hand mouse button. Options on this menu, apart from the default 2D Cursor hit option, allow the User to choose a position for a leader line hotspot with relation to an existing line, or lines, of the displayed drawing. Menu options that are not applicable to the CE are greyed out.

10.3.3 Creating Symbolic Labels

Draft is supplied with a comprehensive set of libraries of standard Symbolic Labels which can be picked and added to a drawing. (A Draft Administrator may have changed the supplied Libraries to company–specific ones.) The Labels can include intelligent text. For example, a Symbolic Label used on a Nozzle could display the Nozzle name and other information automatically complete with associated symbol. A Symbolic Label can only be added to a Layer. To add a Symbolic Label you must have a 2D Area view displayed which includes the relevant View containing a Design element the User wishes to associate a label. Select Create > Label > General/Symbolic from the main menu. The Labels form will be displayed. Select the Symbolic Label Tab. The Library form will also be displayed. The Library form is used to display the standard Symbolic Labels supplied with Draft. Different Libraries may be specified, each of which contains a selection of Label Libraries. The Library form will display those Symbolic Labels present in the Label Library whose name appears on the option button at the bottom of the form. Different libraries can be selected from the option lists. From the Label form select the Attach to option list. There are a number of menus and types to select from. The option selected will then be the only element type for the current creation that a label can be attached to. Selecting the Create New button will create a new SLAB that will be connected to the element type selected in the Attached to option list. The User will be prompted to identify a label from the library first, then to identify the design element in the View to which the label will be attached. Selecting the Create Copy button will create a new SLAB, and the User will be prompted to identify a SLAB that exists on the drawing.

If the element being identified has p-points, the p-point number to be attached to on the element can be entered in the PPOINT box, or clicking on Cursor, will prompt the user to identify a p-point. If the element being identified has p-lines, the p-line name to be attached to on the element can be entered in the PLINE box, or clicking on Cursor, will prompt the user to identify a p-line. The distance along the section is defined as a proportion of the length, and any value less than 1 can be entered in the Proportion field. The rotation of the label can be specified. The Blanking can either be on or off, by placing a check mark in the Blanking box. The margin around the blanking can be specified. The symbolic label can be scaled by entering values in the x and y scale text boxes.


94

www.aveva.com


10.4 Hide/Show Labels

Label visibility can be toggled on/off.

To hide a Label, select: Modify > Label > Label Visibility from the main menu.

The Label Visibility form will be displayed.

Selecting the Scope button will allow the user to select labels for the whole sheet, a selected view or a selected layer.

The Hide and Show options allow the User to select All for all the labels, or Identified allows the User to select the label(s) by identifying them with the cursor in the view. The Display Hidden Labels button will show all hidden labels in a different colour to displayed labels.

10.5 Label Blanking

The geometry for the blanked area is determined by the geometry of the annotation element. For example, a circular label will define a circular area where no 3D graphics will appear. Overlapping 2D graphics, text and other annotation graphics will not be hidden.

If Blanking is switched off, operations such as zooming and panning will be quicker.

Select Modify > Label > Label Blanking and the Blank Labs form is displayed. The Modify Blanking is similar to the Label Visibility form. On the Blank Labs form, there is an option to define the margin around selected labels.

10.6 Label Placement

This facility helps to „tidy up‟ crowded areas of labelling, minimising Label overlap and leader-line crossing. As well as changing label positions this facility may also be used to change Label orientations, text justification, alignments, and the definition of leader-line shapes. Select Modify > Label > Label Placement. The Intelligent Label Placement form will be displayed. The form is divided into two sections, Select and Position. These areas of the form are considered in the sections that follow.


95

www.aveva.com


10.6.1 Intelligent Label Placement Form: Select

This area of the form allows the user to Add or Remove Labels to be spread over the drawing using a spreading list. CE’s Labels: selects an individual label or all the Labels in the current view or layer. Owner’s Labels: selects all the labels of the owner of the CE. Clear: clears the current selection. ID Label: allows the User to select a series of labels. ID Design: allows the User to select a series of labels attached to the identified design element. 2D Window: allows the User to select all the labels within a cursor defined window. List: displays the Select List form. The User can select a predefined list or create a list for this activity.

10.6.2 Intelligent Label Placement Form - Position

Two positioning options are available for Labels; Remote or Local. The User must select the appropriate checkbox then click the Definition button adjacent to the checkbox options. A label definition form will be displayed.

Remote Label Placement Using this option will place labels around the view border. The Remote Label Placement form allows the user to set the positioning parameters for remote Label spreading. Region: the Labels may be spread around a rectangular region defined by the Cursor. The coordinates of the region will appear in the X Y boxes, from where they may be modified. View Margin: the Labels may be spread around a given margin of the current VIEW boundary. Minimum gap between labels: defines the minimum gap between the labels. Use: by default, all four sides of the VIEW border will be used to spread the Labels, but one or more sides may be omitted. Automatic Orientation: allows or suppresses automatic rotation of the Labels along the top and bottom sides of the view boundary.


96

www.aveva.com


An example of remote placement of labels is shown here:

Local Using this option will place labels around significant design elements. The Local Label Placement form allows the User to define offsets that will be applied to the label with respect to the design elements. Selecting the Same checkbox will cause the entered value to be copied into the other window, e.g. In the drawing below the X offset has been set to 25. This will be copied to the Y offset text box when the Enter button on the keyboard is used to confirm the X offset. Selecting the OK button will also have the same effect.

The spread offset of the Labels from their attachment points can be specified directly using the X Offset, Y Offset boxes or indirectly using a Radius and an Angle.

An example of local placement of labels is shown here:

CHAPTER 11


11 2D Drafting

The 2D drafting facility within Draft is used for adding manually-drafted graphic and text details to drawings that have been generated from the Design database. The facility is not intended to be a used as a drafting package. There are three sets of menu options specific to 2D Drafting:

Draw: enables the User to draw 2D Primitives and Local Symbols.

Construct: enables the User to construct lines and other primitives using existing primitives.

Edit: enables the User to change the attributes of a primitive, move primitives and nodes, insert gaps in lines, trim lines and arcs, rotate primitives, reduce a symbol to its basic components.

The basic geometric shapes and text that can be drawn are called Primitives. The primitives exist in the Draft hierarchy as members of Sheet Notes (NOTE), View Notes (VNOT) elements, or Symbol Templates (SYTM). By default, the NOTE and VNOT elements will be created automatically whenever a Sheet or Layer element is created, but the user can create additional NOTE and VNOT elements if required. Primitives that exist as members of a VNOT may have their dimensions and positions defined in terms of 3D Design values.

11.1 2D Drafting Hierarchy

The following diagram shows the 2D drafting part of the Draft hierarchy. It shows the related elements and at what level in the hierarchy they may be created. All of these elements, with the exception of extra Layers, can be created as extra 2D elements and added to the Sheet or View.

SHEE

NOTE VIEW

11.2 Creating Sheet Note & View Note Elements

A Drawing Sheet will have been created with a number of Views and Layers. The Notes layer used for 2D drafting will own a View Note. 2D Primitives associated with a View will be added to the View Note. 2D Graphics and text associated with the main Sheet should be placed in a Sheet Note. Selecting Create > Note from the main menu displays the Create NOTE form where the User is at a View element or above.

The name can be left as default or changed as required.

The position of the User in the hierarchy determines the type of Note created; a Sheet Note (NOTE element) will be created if at a View element or higher, a Layer Note (VNOT element) will then be created if at a Layer element or lower. As each Note is created, they are added to the list of Notes in the Layers toolbar. The displayed VNOT will indicate where primitives are to be subsequently created.

11.3 Creating primitives

To create primitives, first ensure that the required NOTE (or VNOT) is displayed. Selecting Draw > Primitives from the main menu displays the 2D Draughting form.

For all primitives except Symbols, the Point Construction Option Form will be displayed.

The prompt text displayed in this form instructs the User as to the next step of action. The text will vary according to the type of primitive being created. The default option is a 2D cursor hit. This enables the User to position the selected primitive „free-hand‟. The User may pick the point(s) requested, by left-clicking the mouse with the pointer in the appropriate position(s) on the drawing. If the primitive is a graphic, it is drawn as the points are selected. Depending on the type of graphic, it may be necessary to click on Cancel on the Point Construction Option Form when the final point has been selected, in order to complete the graphic. If the primitive is Text, only one point is selected and the Modify Text form is then displayed.

CHAPTER 12


12 Section Planes

Chapter 12 explores the use of Section Planes within a drawing to aid clarity and how they may be defined.

12.1 Section Planes

Draft presents the ability to construct sections through specified Design items using intersecting planes, the results of which can be displayed at View level. All Planes are database items and can therefore be used with more than one View. There are three types of section planes:

Flat Planes

Perpendicular Planes

Stepped Planes This module covers Flat Planes only.

For information on Perpendicular and Stepped Planes Please refer to TM-1206 Drawing Production (Advanced).

When views are defined or modified, the Section Mode option list allows the User to Omit Fractional Components. If this option is selected, any component which is not completely inside the sectioned View will be omitted.

On the Limits tab, if the check boxes (adjacent to the co-ordinate text boxes) are checked, section planes will be created automatically.

All Planes are created and held within a Library structure and are owned by a Planes Library (PLLB). To use a plane to produce a sectioned view of part of the Design, a View Section (VSEC) element which refers to the appropriate plane element in the Planes Library must be created.


120

www.aveva.com


A Planes Library is always created automatically (if the Drawing does not already have one) whenever the User makes a selection from the Create > View > Section menu. The appropriate type of Plane is then created as a member of the Planes Library, being referred to by the VIEW Section.

If the view type is wireline, the view will not be sectioned.

12.2 Creating Flat Planes

Starting at the View level, the creation process is initiated be selecting Create > View > Section Flat from the main menu. A View Section element will be created automatically and the Create a Flat Plane form will be displayed.

The Name text box will contain the automatically assigned Plane name, which can be changed if required.

The required Plane positioning method is selected from the option list located to the right of the Position button, and by clicking the Position button. The positioning options available are:

Explicit: the Explicit Plane form is displayed. Enter the required co- ordinates.

ID Cursor: an appropriate message will be displayed. Click on the required Design item.

ID P-Point: an appropriate message will be displayed. Click on the required p-point.

Cursor: an appropriate message will be displayed, identify a 3D point as required.

The Cutting option list details the available Drawlists. The items to be cut by the plane will be those referred to by the selected list. If World is selected, all items in the owning View‟s Drawlist will be cut. The Direction text box allows the user to define a vector normal to the plane (set to the current View direction by default). A new direction can be entered by typing a value into the text box. If the Centreline Mode checkbox is active then everything included on the Drawlist except the Centre-Line of pipes (if displayed) will be Cut. The Retain Data option lists displays the available options for defining which side of the cut line will be discarded from the display. The default In front of Plane means that everything on the observer‟s side of the plane will be discarded. Having clicked on OK, select Graphics > Update > Design from the main menu in order to update the View contents.


121

www.aveva.com


12.3 Modifying Flat Planes

Flat Planes can only be modified if the User navigates to a View level (or below) in the Draft hierarchy and selecting Modify > View > Section Flat from the main menu. This will prompt the Modify a Flat Plane form to be displayed. This form is very similar to the creation form, differing in that there are two additional buttons: the Sketch button and the Erase button.

The Sketch button will draw the profile of the cutting plane being used.

The Erase button will remove from the screen the drawing aids representing the cutting plane.

Having clicked on Apply, selecting Graphics > Update Design from the main menu updates the VIEW contents.

12.4 Flat Plane – A Worked Example

Navigate to Drawing Sheet View : /DRWG-EQUIPMENT-AREA01/S1/V1 Create a Drawlist for the View: DRWG-EQUIPMENT-AREA01/DRAWLIST/FLAT_PLANE and populate as follows:

Section Plane is created as follows Select Create > View > Section > Flat from the main menu.


122

www.aveva.com


Populate the form with the following information:

With the position option list set to Explicit…Select the Position button, Set the following co-ordinate East 0mm North 0mm Up 107820mm Select the Apply button, before clicking Dismiss Select the OK button on the Create a Flat Plane form and select Graphics > Update Design from the main menu. Text and 2D Draughting can be employed to highlight section influence within drawing:

Note: Hatching could be applied to the view by setting the hatching Rule of the view to TT/DRA/PRJ/HRUL/GEN/Hatch-Equip.


123

www.aveva.com


Exercise 21 Section Planes

Navigate to Drawing Sheet: /DRWG-EQUIPMENT-AREA01/S1 Create a Drawlist for the Sheet: DRWG-EQUIPMENT-AREA01/DRAWLIST/COLM_SKIRT and populate with the equipment elements C1101-SKIRT and C1101-COLUMN from SITE-EQUIPMENT-AREA01 as follows:

Using Sheet: /DRWG-EQUIPMENT-AREA01/S1, create four views with a viewing direction of North, East, Down and Iso3 respectively.


124

www.aveva.com


Set the Drawlist Ref… for each view to the Drawlist: DRWG-EQUIPMENT-AREA01/DRAWLIST/COLM_SKIRT

View: C1101 Skirt Detail (North) Position: X160.00mm, Y180.00mm centred on the Skirt element

View: C1101 Skirt Detail (East) Position: X405.00mm, Y180.00mm centred on the Skirt element

View: C1101 Skirt Detail (Down) Position: X655.00mm, Y180.00mm centred on the Skirt element

View: C1101 Skirt Detail (Iso 3) Position: X900.00mm, Y180.00mm centred on the Skirt

Create Flat Planes in each view with a direction of your choice (or as suggested above). Retain the data In Front of Plane in all cases and note the effect on the Design elements in the views. The planes can be positioned by selection position using the Id cursor in one of the other views.

Modify all planes to retain data Behind Plane and note the effect on the Design elements in the views.

Modify the Direction of each plane in turn and note the effect on the Design elements in the view. Create a new Drawlist, containing just the C1101-SKIRT, modify the Flat Section on each view to cut just the Drawlist containing the C1101-SKIRT and Retain Data In Front of Plane.

14 Printing and Plotting

14.1 Printing

Selecting Utilities > Print CE… will display the Print CE form.

Once the Colour Correction Mode has been selected the User can then click on either the Not Scaled or Fit to Page buttons.

This will open a standard Print form to allow the User to set the various print preferences:

14.1.1 Colour Correction Options

The Colour Correction Mode options define how colour is to be handled when the drawing is output:

Standard will use the defined colours of the drawing unchanged.

Colour Plus converts all grey, black and white colours to black if the background is white and

white if the background is black. This adds contrast to the output drawing.

Greyscale converts all of the colours to an equivalent shade of grey.

Black & White: all of the colours are set to black if the background is white and to white if the background is Black.


134

www.aveva.com


14.1.2 Print CE Options

The Print CE… options define how the scaling of the drawing is to be handled:

Not Scaled will print the Drawing Sheet without scaling.

Fit To Page will print the Drawing Sheet and automatically adjust the drawing size to fit the paper.

14.2 Plotting

Using this option gives the User more control over the output file, for example size and frame, and allows the production of an AVEVA Pseudo Plot file for use within AVEVA models e.g. IsoDraft. The AVEVA Pseudo Plot file can be converted into alternative plotting formats for example HPGL or Postscript. It is progressively common to produce the output in the more modern plotting formats such as PDF. The use of these newer plot formats is particularly important if the Drawing Sheet has been produced using True Type Fonts as the use of True Type Fonts is not supported in the AVEVA Pseudo Plot file.

14.3 Plotting Drawing Sheets and Views

Selecting Utilities > Plot CE… will display the Plot form. It can be used to produce plots of Views or Sheets depending on the Hierarchy position.

14.3.1 Output File

The Output file area of the form is used to specify the destination Directory and Filename; the fields can be altered as required. The Filename extension will change automatically when selecting output formats of different types for example *.pdf, *.jpg, *.bmp.

The available file types are discussed later in the Chapter.

14.3.2 Plot File Size

The Size pull-down controls the output size, for example A0, A1 and A2 etc. The User can opt to have a Frame and Cutmarks by checking the relevant box, in addition to defining the Border size.


135

www.aveva.com


14.3.3 Type of Plot Output

The User can choose to produce a Plot File, a Plot or both File and Plot via the available radio buttons.

The Preview button is discussed later in this chapter.

14.3.4 Plotters

Selecting the Plotters button displays the Plotting Options form showing the available Plotters
