Introduction to Draft

1-2

The strengths and structure of PDMS PDMS is a powerful suite of facilities, for the design of Process Plant, the emphasis being on maximising both design consistency and design productivity: The design modelling functions incorporate a degree of apparent intelligence

that enables them to make sensible decisions about the consequential effects of many of your design choices. This allows you to implement a sequence of related decisions with a minimum of effort.

You can incorporate modifications into your design at any stage without fear of invalidating any of your prior work, because data-consistency checking is an integral part of the product. PDMS automatically manages drawing production, material take-off reports, and so on, by reading all design data directly from a common set of databases, to prevent errors from being introduced by transcribing information between different disciplines.

The applications let you check all aspects of your design as work progresses. This includes on-line interdisciplinary clash detection, so the chances of errors and inconsistencies reaching the final documented design are reduced to an exceptionally low level.

The applications are controlled from a graphical user interface. This means that all design, drawing and reporting operations are initiated by selecting choices from menus, and by entering data into on-screen forms. For ease of use, pictorial icons also represent many common actions.

On-screen help is available to assist you whenever you need help. PDMS is subdivided into modules, which are used to carry out specific types of

operation. This guide covers the Draft module, which is used for generating annotated and dimensioned drawings of 3D models, produced in the Design module.

The structure and functions of Draft Draft is the drawing production module of PDMS. It allows you to generate fully annotated engineering drawings directly from data in the PDMS Design model. Drawings can be easily updated to reflect changes in the design model. Within Draft there are applications that are used for specific functions associated with the production of drawings. These applications are called: General Auto Drawing Production Autodraft.

The functions of the applications, together with some notes on administration, are discussed in the following sub-sections.


1-3

General functions The Draft Graphical User Interface has been designed to allow you to generate and retrieve industry-standard engineering drawings quickly and efficiently. You can then add dimensioning and other annotations. You do not need to make any calculations or input any data, as all annotation information comes directly from the design model. Drawing Creation You select the particular part of the design model and the direction and scale to use. The design model can be viewed from any angle at any scale, including isometric views, with perspective if required. The appearance of the 3D graphics is controlled from representation rules that are pre-defined by the project administrator. This allows different types of design items to have different line styles applied to them. You can select the required representation during view creation. Various levels of wireline and hidden-line removal can be used. Sectional views can be generated by the creation of flat or stepped section planes, and there are no restrictions on the number of planes created or the selection of items that can be sectioned. The scale of the 3D graphics can be selected from a set of Metric, Architectural and Engineering values, with the option of an automatic scale selection to use the largest scale possible for the given design data and drawing sheet size.

Hierarchy Facilities are available for specifying details of the hierarchy within the Draft database for the location of the drawings and their sheets.

Labelling Labels can be attached to any design element and used to display any attribute of the element. You can control the format, content and appearance of the labels, with suitable project defaults defined by the administrator. Direct reference to the design data, combined with a simple update annotation operation, means that the annotation always reflects the current state of the design model. The position and orientation of the labels can be modified graphically, to ensure a clear drawing layout. Automatic labelling (Autotagging) Labels can be automatically generated for a set of design items that match a tagging rule. The rule sets determine the type of label and which design items the labels will be applied to. For example, you could label all nozzles that have a bore of >100mm and

AutoDRAFT application This application is the Draft two-way interface to AutoCAD. (It is not included in the tutorial exercise in this manual.) It is possible to transfer a Draft drawing directly across to AutoCAD, where some users prefer to perform final annotation before drawing issue. The transferred drawing maintains the exact style and representation as set from Draft. The user can develop symbol libraries and drawing frames in AutoCAD and import these directly for use in Draft prior to returning the drawing from AutoCAD into Draft.

Administration This Guide only deals with the Draft User Applications. If you have administration rights within Draft, you will be able to use the Administration applications. For more information see the VANTAGE PDMS Draft Administrator Application User Guide. A brief summary of the Administration facilities follows. The Draft administrator uses the administration application to customise Draft, by setting default attributes and creating libraries of drawing frames, symbols and labels. The Administrator can set default representation rules, labelling rules, naming conventions, line styles and hatching patterns. Template drawings, which contain predefined drawing data, can be set up, thus reducing drawing creation time. Symbology The Draft administrator can generate suites of symbols to be used in both 2D annotation and as part of a symbolic label definition. The symbols are built up from standard 2D annotation elements and can be created by grouping the existing 2D annotations. The library approach to symbol definition maximises drawing consistency, whilst minimising the required storage space for the symbol itself.

Session 2 Getting Started


Use the mouse and elements of the windows, menus and forms from the PDMS graphical user interface.

Log in to PDMS. Use on-line help.

Basic information This section is intended for readers who are unfamiliar with computer practices. It provides information on the use of the mouse and describes the elements that regularly appear in the windows of the graphical user interface.

Using the mouse You use the mouse to steer the graphics pointer around the screen. The appearance of the pointer changes according to the type of display item that is underneath it. There are three buttons on the mouse. These perform different tasks depending on the type of window, and the position occupied by the pointer within the window. The left-hand mouse button has these functions: On a graphical view, clicking the left-hand button with the pointer over a Design element in a Drawing results in that element being selected in the Design Explorer see section 3.6.1. Clicking on a Draft element (for example a Dimension or a Label) results in that element being selected in the Draft Explorer see section 3.5.2. In a sequence of menus, dragging with the left-hand button activates the command represented by the highlighted menu option when the button is released. On a form, the effect varies according to the selected item.

The middle mouse button or wheel is used primarily to manipulate the graphical view contents. The right-hand button is used to access pop-up menu options specific to the

graphical view window.

Using menus Menu options in pull-down or shortcut menus (the menu revealed by pressing and holding down the right-hand mouse button) can be in any of three formats:

Standalone options initiate an action immediately.

Options followed by three dots display a form requiring further input from the user in order to complete the action.

Options followed by a pointer, display a subsidiary menu that offers a further range of options. Throughout this guide, related selections from menus are abbreviated using the > symbol as a separator. For example: Select Utilities>Reports>Create means: a) Select Utilities from the bar men. b) Select Reports from the resulting pull-down menu

c) Move the pointer to the right and select Create from the resultant submenu.

Using forms Forms are used both to display information and to let you enter new data. Forms typically comprise an arrangement of buttons of various types, text-boxes, and scrollable lists. Input to a form is usually by use of the mouse and keyboard. While you have access to a form, you can change a setting, return to the initial values, accept and act on the current data, or cancel the form without applying any changes, according to the nature of the form. Forms can include any of the following elements, the uses of which are described in the following sections: text boxes drop-down lists option buttons check boxes scrollable lists action buttons.

Using text boxes Text boxes are the areas where you type in alphanumeric data such as names or dimensions. A text box will usually have a label to tell you what to enter. A text-box often contains a default entry (such as unset) when first displayed. Some text boxes accept only text or only numeric data, and entries with the wrong type of data are not accepted. To enter data into a text box: Click in the box to insert the text-editing pointer (a vertical bar). Type in the required data, editing any existing entry as necessary. (You may

need to delete the existing entry first.) You can edit the contents of the text box by moving the pointer using the arrow keys or by moving the pointer with the mouse and clicking the left mouse button. You can delete text by using the Backspace key to delete characters to the left-hand of the pointer or the Delete key for those to the right-hand. When you have finished, confirm the entry by pressing the Enter (or Return) key. A yellow background highlights any text box with an unconfirmed setting.

Getting Started

2-4

Using drop-down lists Drop-down lists let you choose one option from a multiple selection. The list will usually have a label to tell you what you are setting and will show the current selection. They typically have the following appearance:

To change the setting, click on the down arrow or button face to reveal the full list of available options. Then pick the required option. When the arrow has a bar under it, clicking on the button leads to another form, at which the required option can be selected from a scrollable list.

Using option buttons Option buttons (radio buttons) are used to select one, and only one, from a group of options. The selection is mutually exclusive, so that selecting one option deselects others in that group automatically. They typically have the following appearance:

Option selected

Option not selected To change the selected option button in a group, click the required button.

Using check boxes Check boxes are used to switch an option between two states, typically set and unset. Unlike option buttons, they do not interact, so that you can set any combination of check boxes at the same time. They typically have the following appearance:

Set

Unset

Getting Started

2-5

Using scrollable lists A scrollable list is displayed as a vertical list of options within the form, with vertical and horizontal scroll bars along its sides. To select an option, click on the line you want. The selected line is highlighted. Some scrollable lists let you make only a single selection, so that selecting any option deselects all others automatically. Other lists let you make multiple selections, with all selected options highlighted simultaneously. You can deselect a highlighted option in a multiple-choice list by clicking on it again (repeated clicks toggle a selection).

Using action buttons Most forms include one or more action buttons. You use these to tell PDMS what to do with the details you have entered in the form. The common action buttons are:

Tells PDMS to accept the current form settings, and closes the form.

Cancels any changes you have made to the form, and closes the form.

Tells PDMS to accept the current form settings, and leaves the form displayed for further use.

Cancels any changes you have made to the form, and leaves the form displayed for further use.

Closes the form, keeping the current settings. Some forms contain more specific types of control button, which carry out particular command options. The action is indicated by the name of the button (such as Add or Remove).

Responding to alert forms Alert forms are used to display information such as error messages, prompts and requests for confirmation of changes. You should respond by carrying out the prompted task, or by clicking on the control buttons on the form (usually an OK or Cancel button).

Getting Started

2-6

Exercise 1 - Logging in Your trainer will have provided for you a PDMS Icon.

Start PDMS by double-clicking on the PDMS icon. The following VANTAGE PDMS Login form appears, at which you specify a number of details at the start of your session.

Click on the VANTAGE PDMS Login form to make it active. Note: The following entries made at this form are specifically for the tutorial. Those required for your own project will be different. Enter, or select using the dropdown list button, the name of the Project in which you want to work. For this training we are using the SAM project. Enter, or select using the dropdown list button, your Username. Your trainer will advice you of your username, password and MDB, it will be of the form USERA, USERB, USERC etc. (in upper case). Enter your allocated Password, which is A for USERA, B for USERB and C for USERC etc. (in upper case). The textbox displays an asterisk for each entered letter. Enter, or select using the dropdown list button, the part of the project Multiple Database (MDB) you want to work in. For USERA the MDB is TRAINA, USERB the MDB is TRAINB, USERC the MDB is TRAINC etc. Using the dropdown list, select the name of the module you wish to use. This is Draft.

Getting Started

2-7

Make sure that you leave the Read Only box unchecked, so that you can modify the database as you work. You must specify which files (Load from) to load at startup. The options are the application default settings (Macro Files) or a customised setup saved during an earlier session (Load from Binary Files). During this training we will always select Macro Files as we learn by repeatedly doing the same thing. The login form will be similar to the one above. Click on the OK button.

The Draft startup display When Draft has loaded, the Draft Main Display occupies the screen. The Main Display contains a number of sub-windows (more properly forms). The main display would typically appear as:

You can reposition or minimise these forms at any time by using the standard Windows management controls. Note that all the forms in the Draft Main Display (except the Drawing Window) can be set to the standard Windows Dockable, Hide, Floating or Auto Hide display modes by selecting from the shortcut menu in the title bar of the form. See the PDMS online help for more details. The features of the main window, as illustrated above, are summarised here. The tutorial exercise explains when relevant elements are selected to achieve particular objectives. For a detailed description of all elements, reference should be made to the online help.

The Draft Display

3-3

Title Bar This shows that the current PDMS module is Draft, and the application name, which in this case is General. The Main Display is maximised and therefore [Main Display] appears in the title bar.

Main Menu Bar This displays the names of the available drop-down menus. The menu bar can be repositioned and resized as described for toolbars (see below). For reference, the online help provides details of all menu options.

The Toolbars The toolbars provide shortcuts to various Draft functions. The toolbars will be introduced and described as the training progresses. Each toolbar is also described in the Draft online help. A menu showing the available toolbars can be displayed by positioning the pointer over a toolbar and clicking the mouse right-hand button. The menu enables you to display or hide a selected toolbar, the menu is displayed using the RH Mouse Button on the Main Menu Bar.

You can reposition and resize the toolbars as required using standard Windows manipulation methods, and detailed toolbar manipulation information can be found in the online help for any Microsoft Office product. In summary: To move a toolbar, rest the pointer over the vertical dotted line at the left-hand edge of the toolbar, press and hold down the left-hand mouse button and move the toolbar as desired:

The Draft Display

3-4

(If you only move the symbol horizontally, you are able to move the toolbar within the main toolbar.) If you resize the main Draft window to make it smaller, you will find that the toolbars will also reduce in size and a Toolbar Options symbol will appear at the right-hand end of the toolbar:

Left-clicking anywhere on the Toolbar Options symbol will bring up a graphical menu enabling you to select the missing icons from the toolbar. For example:

In this case the Default toolbar normally appears as:

The Main Display forms The forms within the Main Display window will be introduced and described as the tutorial in this manual progresses. Each form is also described in the Draft online help.

Status Line

This displays prompts and other information about Draft's current operation. You should look at it frequently, especially if the system appears to be waiting for you to do something. It will always prompt you for any input or action, which is required to carry out the next step of your current activity.

If the prompt lets you repeat a task an unspecified number of times, such as picking a selection of items using the pointer, you must press the Escape key when you have finished indicating that you are ready to move to the next operation.

Drawing Window

The above illustration shows the Main Display window in restored size. Drawings produced by Draft are displayed in this window. It has a pop-up menu, activated by the mouse right-hand button.

The Draft Display

3-5

Drawing Window toolbar

This contains buttons that are used when modifying and creating drawings. From top to bottom, they are Reset Limits, Modify Mode, Snap to Grid, Display Grid and Restore View 1, 2, 3, and 4.

Using on-line help Most bar menus end with a Help option. Where available, on-line help gives detailed instructions on the use of the forms and menus in each application. You are advised to make full use of the on-line help facilities whenever you want clarification of any operations, during the later steps of the exercise. The Help option gives you the following choices from its submenu:

Help>Contents

This displays the Help tri-pane window with the Contents tab at the front so that you can find the required topic from the hierarchical contents list.

Help>Index

This displays the Help tri-pane window with the Index tab at the front so that you can find all topics relevant to a selected keyword.

Help>Search

This displays the Help tri-pane window with the Search tab at the front so that you can enter a word or words to search for.

Help>About

This displays information about the version of PDMS that you are using. More Info... lists the version numbers of the libraries being used by the displayed version of PDMS. Pressing the F1 key at any time will display the help topic for the currently active window.

The Draft Display

3-6

Exercise 2 - On-Line Help Experiment with each of the Help options until you understand the search and navigation facilities for finding specific items of information. Use the F1 button to read the help texts for any forms, which you can currently see on your screen. When you are ready to continue, close any forms that you have been experimenting with as follows:

If a form has a Dismiss button, click this button. If a form has its own menu bar, select Control>Close from that menu. Close any Help windows, which are displayed by double clicking in the control

box in the top left-hand corner of each window. Do not close the Main Display window, because you will use it in the next part of the exercise.

The Draft Display

3-7

Loading an existing drawing sheet

We need to load an existing drawing sheet from the Sample project, so that the exercise can continue with practising the use of the mouse. Before we load the sheet, the following short explanation of how elements are stored in the Draft database hierarchy, will be helpful.

The Draft database hierarchy

The Draft database is a tree structure, which for reference purposes is illustrated in Appendix C. The above hierarchy shows the part of the tree that is relevant to displaying drawings and sheets. The World is the top element. The next level down in the structure is a Department. The World can own several Departments, which are known as its Members, and the World is known as the Owner of the Departments. Departments can own Registries, which can own Drawings, which can own Sheets. Later we will discuss the members of Sheets, but knowledge the above hierarchy is sufficient for the purpose of displaying a sheet.

The Draft Display

3-8

You can view the elements of the hierarchy in the Draft Explorer, but you cannot display them graphically. For more details of these elements, see the VANTAGE PDMS Draft User Guide, Part 1.

The Draft Explorer

At the top-left of the Main Display you will see the Draft Explorer form. Click the + sign to the left of the World icon:

Clicking the + sign shows the elements under the World which, in the Sample project, as supplied, looks like this:

When you look at the Draft Explorer you will see that the first (top) element is the WORL (world) element. The World is shown in the Draft Explorer as * and cannot be either created or deleted. The World signifies owns all members displayed below it. Note the Filter tool. This enables the list of items to be filtered according to whether the user is a General User or an Administrator. The Administrator will be able to see more than a general user, but display of the DEPT (Department) and REGI (Registry) administrative elements will be skipped, only the contents of (Drawings or Libraries) of these elements will be displayed. Select the Filter check box, then select General User or Administrator from the adjacent list to see the effects of using this tool. There are two Departments supplied with the product:

Project_Libraries contains sample sheets. Master_Libraries containing standard backing sheets, symbol libraries etc.

The Draft Display

3-9

PDMS has a serialisation feature, which means it will remember the state of the Main Display when you leave Draft and re-enter it, so you dont have to remember how the display looked and recreate it.

Exercise 3 - Displaying the sheet

In the Draft Explorer, select the DEPT /Project_Libraries by clicking on the + sign next to it with the left-hand mouse button. The hierarchy, shown in the Explorer, will then be expanded to show the REGIs owned by the DEPT. Continue to work down the tree by selecting the following elements:

REGI /DRA/PRJ/TMP/PIPING DRWG /DRA/PRJ/TMP/PIPING/A0 SHEE /DRA/PRJ/TMP/PIPING/A0/S1

Note that the element selected in the Explorer is known as the Current Element, that is, the element on which you want to carry out the next operation. Display the Working Sheet toolbar, if it is not already displayed, and then display the /DRA/PRJ/TMP/PIPING/A0/S1 Drawing Sheet in the Drawing Display window by clicking on the button on the toolbar:

The Name of the sheet will be displayed in the Working Sheet toolbar list next to the button (you may need to resize the toolbar to see this) and the currently selected Layer will appear in the Layers toolbar. The sheet will be displayed in the Drawing Display.

A large selection of Layers (selectable from the Layers toolbar list or the Draft Explorer) exist below the Sheet (below View level), ready for when you come to create Dimensions, Labels or 2D primitive annotation. (This will be described later in the training)

The Draft Display

3-10

The Sheet displayed is a Draft backing Sheet containing one empty view:

Using the mouse and keyboard to manipulate the view of the sheet

Mouse buttons

Left-hand button

As previously mentioned, clicking the left-hand button with the pointer over an element makes the element the Current Element. The element may be a Design element (part of the engineering item displayed) or a Draft element (for example, the outline of the drawing sheet, a label, or a dimension). If a Draft element is clicked, the Draft Explorer changes appropriately, for example:

The middle button allows you to increase and decrease the scale of the displayed view, as follows:

Windowing in. Position the pointer at one corner of the imaginary rectangle enclosing the part of the sheet that you want to fill the Drawing display. Hold down the middle button and move the pointer to the diagonally opposite corner of the rectangle. A 'rubber band' rectangle, enclosing the area, will be displayed. When you release the mouse button, the chosen area will fill the display area.

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.

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.

If your mouse has a wheel, then rotating the wheel away from you will zoom in, towards you will zoom out.

Right-hand button

Clicking the right-hand button, when the pointer is in the main display, activates a shortcut menu. At this stage, the only option that you should use is Reset Limits. The effect of this is to zoom out until the full extent of the Sheet is displayed.

Zooming and panning

Zooming

We have just discussed Windowing in, Zooming in and Zooming out using the mouse middle button or wheel. Here are some additional features:

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 (see the

diagram below).

Panning

Panning (moving the displayed area across the overall drawing) can be achieved by the following methods, once you have zoomed in.

Use the mouse pointer to drag the Drawing display slider controls. Use the up/down, left/right arrow keyboard (see diagram below). As required,

hold down the Ctrl key to increase the step size by a factor of 10. Or, as required, hold down the (shift) key to decrease the step size by a factor of 10.

Use the numeric keypad even-numbered keys, as shown below:

Arrow keys pan in directions shown

Numeric Keypad keys 2, 4, 6, 8 pan in directions shown by half view width.

Exercise 4 - Viewing Controls Now you can familiarise yourself with some of Drafts viewing controls. Experiment by using the mouse, as described above.

Switch on the Display Grid, by clicking on the Display Grid button. This is on the toolbar at the side of the Drawing display window. Note: 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. When you are ready to continue, close any forms that you have been experimenting with. Close any Help windows that are displayed, by clicking in the control box in the top left-hand corner of each window. Hide the Grid using the Grid Icon

Do not close the Main Display window, because you will use it in the next parts of the exercise.

Session 4 Setting up the Hierarchy to Create a Drawing Sheet


Create a Draft Hierarchy to start Drawing Production. Create a Drawing from a Template or Explicitly. Create a Sheet from a Template or Explicitly


The use of different Administrative elements in the Draft hierarchy. The difference between Drawings and Sheets created by Templates or Explicitly.

Setting up the Hierarchy to Create a Drawing Sheet

4-2

This Chapter describes how to create a drawing sheet belonging to a new branch of the Draft hierarchy. There is a method of creating a Drawing Sheet from a standard template with a single click. That is described at the end of this Session, but first we will describe the full way of creating a Drawing so as to familiarise you with part of the Draft database hierarchy and some Draft concepts. An administrative element can be created only at one level lower than an existing element, which will then own it. Consequently, as we are going to create a drawing in a new branch of the hierarchy, we must create the upper elements of that branch, firstly a Department and then a Registry, before we create the Drawing and its Sheet.

Creating a Department

Departments can be created only under the World level. From the bar menu at the top of the screen, Create>Department (It doesnt matter where you are in the database hierarchy, Draft will automatically create the Department at the correct level.) The Create DEPT form is displayed, which you can use to name your DEPT. A default name, DEPT1, is shown in the Name text box.

You would normally change the name of the Department to something meaningful, but in the following form examples it is left at its default. If you want to change the name, move the pointer into the text box and click the left mouse button. Type the name, making sure that you do not use spaces.


4-3

When you click OK on the Create DEPT form, the Department Information form is displayed.

The Department Information form shows the name of the DEPT and gives you the opportunity to automatically create a Registry and/or to set up attributes of the Department. To view the range of available attributes, click on the Attributes button. The Department Attributes form is then displayed.


4-4

The attributes set at this form are 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 Draft Administrator would normally se the default attributes, and so just click on the Dismiss button to close the form. Ensure that the Create Registry checkbox on the Department Information form is selected, as it is when the form is first displayed, when the OK button is selected the Create REGI form will be displayed.

Creating a Registry

The Create REGI form should be displayed at the end of the previous step. However, if the Create Registry checkbox on the Department Information form was off, the Create REGI form does not automatically appear. In these circumstances, it can be displayed by use of the Create>Registry option on the bar menu.

As for the equivalent form for a Department, this form allows you to change the default name. The default name as REGI1. When OK is selected the Registry Information form will be displayed.


4-5

The Registry Information form shows the name of the Registry and DEPT and gives you the opportunity to automatically create a drawing and/or to set up attributes of the Registry. The Create Drawing checkbox enables you to select whether or not a drawing is automatically created. If the checkbox is selected, then the method of drawing creation will depend on whether you select the Explicitly or From Template option button. The difference is explained later. The Attributes button displays the Registry Attributes form. This form is not illustrated here, as the attributes are as shown on the Department Attributes form we will use the default attributes. If the Create Drawing checkbox and the From Template option button are selected. The Create DRWG form is then displayed.

Again the drawing Name could be changed the default DR1, when OK is selected the Drawing and Sheet Templates form is displayed:


4-6

Creating Drawings and Sheets

There are two methods of creating Drawings, Explicitly or From Template. Both methods are available, regardless of whether you create the drawing by selecting Create Drawing button on the Registry Information form, or by selecting Create>Drawing at the Draft General bar menu.

From Template

If you create a drawing from a template, several other elements will be created automatically. The Drawing will own a Sheet, which will own at least one View. The View will own several Layers, which are discussed later. There may be other 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, most of which are set up by the System Administrator. Users can only extract information from libraries; not change them. Libraries are used to store things like symbols and Drawlists (which you will use later to define the contents of a View). Libraries are accessed by the Application automatically and, therefore, you will not need to access them directly. You should not try to rename or delete Libraries or their members. The Drawing and Sheet Templates form enables you to select the source of the template, the drawing size and the Sheet number of that drawing. Note: At the top of the form, the Mode is set to Drawing Creation. If the form is used for creating a Sheet, the Mode is set to Sheet Creation, but otherwise the form is unchanged. The Options drop-down list shows the drawing disciplines that contain the drawing template libraries, as set up by the System Administrator. An example of this is the equipment template, which is /DRA/PRJ/TMP/EQUI or the A0 option (/DRA/PRJ/TMP/EQUI/A0) from the Drawings list (this one is already selected by default). The template includes a single sheet (/DRA/PRJ/TMP/EQUI/A0/S1) displayed and selected in the Sheets list. A Sheet having all the attributes of the template will be created, and displayed in the Drawing Window, as shown below.


4-7

We have now created the administrative elements that define the Drawing Sheet. In the next Session we will specify which engineering items are to appear on the Sheet. To do this, we modify the View created by the template. There is a quick way to create a Drawing Sheet. Simply click on the Create New From Default Template button on the toolbar of the same name:

A Drawing Sheet (looking just like the one we have just created) will appear in the Drawing View. Note that there has been no need to name the Sheet; it is named automatically (as /DR1/S1 if it is the first such Sheet to be created) and the hierarchy above and below it is created automatically. (You can select drawing templates other than the default; see the Draft online help for details.)


4-8

Explicitly

If you create a drawing explicitly, you will have to use the Create options on the main bar menu to create all of its member elements, such as Sheets and their Views. Create > Drawing > Explicitly

The Drawing Definition for is displayed, the Drawing Title, Date and Drawn By should be entered:

You must remember to Select Apply before you Dismiss the form. As you are creating the Drawing Explicitly you must not create at least one sheet. Create > Sheet > Explicitly


4-9

You should specify the Sheets Title and select the Sheet Size and Backing Sheet requirement.


4-10

Exercise 5 Creating Drawings and Sheets Navigate to the World in your Draft database and create a Department named TRAINING_DEPT. Make sure that the Create Registry checkbox on the Department Information form is checked and create a Registry named TRAINING_REGI. On the Registry Information form click the Attributes button to display the Registry Attributes form and note the settings that may be made from the form. Do NOT make any changes to the attributes. Dismiss the Registry Attributes form to go back to the Registry Information form.. Make sure that the Create Drawing checkbox on the Registry Information form is checked, click the Explicitly radio button and create a Drawing called DRG_1. On the Drawing Definition form give the drawing the title GENERAL ARRANGEMENT , type your initials in the Drawn By text box and click the Apply button and dismiss the form. Your Draft Explorer should now look like this:

Note the Library (LIBY element), owned by the Drawing, that has been created automatically. Click on the LIBY and note the Drawlist Library (DLLB element) and Tagrule Library (TRLB element) that have also been created. Click on the DLLB and note that a default Drawlist (IDLI element) has been created.


4-11

Navigate to the DRWG and select Create>Sheet>Explicitly from the main menu to display the Create SHEE form, noting the default name that is given. Modify the Sheet name to /DRG_1/SHT_1 and click OK to create the Sheet. On the Sheet Definition form give the Sheet a title of STABILISER EQUIPMENT, make sure that the Sheet size is A0, click the Reference radio button and select /DRA/MAS/BACKS/MET/A0 from the pull-down list.

Click the Apply button and dismiss the form. Note that you now have a Sheet outline and backing sheet in your graphics area. Create a new Sheet owned by the same Drawing with a different Sheet size. Create new Drawings and Sheets including the use of Templates from both Drawing and Sheet level. Note the differences in creating from Templates and Explicitly.

Views

Note: PDMS 11.6 introduces a new method of populating drawing sheets using the 3D View of the design model within Draft. This will be explained later. This chapter continues by describing the traditional method of defining and populating a View. This method is still valid, and the tutorial steps that follow are useful in introducing the fundamental concepts of View creation and population. VIEW elements are set-up to show a projection of elements from the Design database. Dimensions, annotation and 2D elements can then be added to the view to complete the drawing. A VIEW element has attributes which:

Define the size, position and orientation of the region on the Sheet that the VIEW occupies

Define the viewing parameters e.g. view type, style, viewing direction, scale, etc.

Refer to a Drawlist that contains a list of the Design (or Catalogue) elements which make up the View picture.

You must be at Sheet level or below before you can create a VIEW. The menu offers options for creating Limits-Defined, UserDefined and Detail views.

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 matchlines with text showing the coordinates of the View limits.

User-Defined View

User-Defined Views are used to draw individual items or groups of items in the design model, when the volume or limits of the items are not known. The size of the frame is independent of its contents. The scale can be automatically set to fit the design elements into the available view frame area. This Session covers the creation and modification of User Defined views only. See Module 20 Advanced Drawing production for details of Limits-Defined and Detail views.

View Creation

5-3

A Drawlist controls the Design elements displayed within a view. The creation, modification and control of Drawlists are explained later in this session. If you create a Drawing or Sheet from a template, one or more views will usually be created when the template is copied if the Draft Administrator has included them during creation of the template. The following session describe the creation of views on Explicitly created Sheets, where no views have been included in the template or where additional views are required.

Creating User-Defined Views

From the DRAFT General bar menu select Create>View>User Defined to display the Create View form. A default view name will be automatically assigned, which you can change if you wish. On completion click on OK and the VIEW will be created. The view frame will appear as a rectangle positioned in the centre of the Sheet and the User-Defined View form will appear.

The User Defined View form menu allows you to manipulate the view frame, the position of the Design elements within the view and the contents of the Drawlist that contains the Design elements displayed in the view.

View Creation

5-4

Manipulating a View Frame

The Frame form menu on the View form enables 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 be on the Sheet. The menu has the following options: On/Off toggles the display of the view frame on and off. Size This option has a sub-menu that allows you to set the size of the view frame in different ways:

Cursor displays the Point Construction Option Form that enables opposing corners of the view frame to be selected graphically. Explicit displays the Explict Frame Size form that enables you to resize the frame by defining its size in terms of Sheet co-ordinates or proportions.

Size By Ratio text boxes can be used to define the extent of the view frame in X,Y Sheet proportions. For example, From XR 0.25 To XR 0.75 would give a view frame centred in the Sheet in the X direction and occupying 50% of the Sheet width. Setting the XR or YR values will cause the Width or Height values to change automatically. Conversely, setting the Width and/or Height values will cause the XR/YR values to change automatically giving a view frame centred on the Sheet in the appropriate direction. Size By Coordinates is similar in its operation except that sizes are expressed in millimetres. Co-ordinate 0,0 is at the bottom left hand corner of the Sheet.

View Creation

5-5

Copy Size This option has a sub-menu that allows you to copy the Width, Height or Width and Height of another view on the Sheet: Width will ask you to identify (with the cursor) a view whose width you wish to copy. The width of the current view will then change to be the same as that of the identified view. Height will ask you to identify (with the cursor) a view whose height you wish to copy. The height of the current view will then change to be the same as that of the identified view. Width & Height will ask you to identify (with the cursor) a view whose width and height you wish to copy. The width and height of the current view will then change to be the same as that of the identified view. Position This option has a sub-menu that allows you to position the frame in different ways: Cursor enables you to use the cursor to move the view frame by first nominating a point in the view, i.e. Centre, Top Left, Top Right, etc.,from the sub-menu. The nominated point will move to the cursor position when the lefthand mouse button is clicked. Explicit enables you to move the view frame by defining its Sheet position in terms of Sheet co-ordinates or proportions.

Position By Ratio text boxes can be used to position the centre of the view in X,Y Sheet proportions. For example, XR 0.5, YR 0.5 will put the centre of the view at the centre of the Sheet. Position By Co-ordinates is similar in its operation except the position is expressed in millimetres. Co-ordinate 0,0 is at the bottom left hand corner of the Sheet.

View Creation

5-6

Align This option has a sub-menu that allows you to align a specified axis or edge of the current view with the same axis or edge of another selected view on the Sheet. Centre Vert will ask you to identify (with the cursor) a view whose centre you wish the current views centre to align with vertically. The position of the current view will then change to align the view centres vertically. Centre Horiz will ask you to identify (with the cursor) a view whose centre you wish the current views centre to align with horizontally. The position of the current view will then change to align the view centres horizontally. Top will ask you to identify (with the cursor) a view whose top edge you wish the current views top edge to align with. The position of the current view will then change to align the views top edges. Bottom will ask you to identify (with the cursor) a view whose bottom edge you wish the current views bottom edge to align with. The position of the current view will then change to align the views bottom edges. Left will ask you to identify (with the cursor) a view whose left edge you wish the current views left edge to align with. The position of the current view will then change to align the views left edges. Right will ask you to identify (with the cursor) a view whose right edge you wish the current views right edge to align with. The position of the current view will then change to align the views right edges.

View Creation

5-7

Setting the Centre of Interest of a View

The View form menu enables you to toggle the display of the view on or off, set the Design co-ordinates corresponding to the centre of interest of the view and offset the Design element graphics with respect to the centre of the view. The menu has the following options: On/Off toggles the display of the view on and off. Centre This option has a sub-menu which allows you to select the centre of interest of the view in different ways: Identify will ask you to identify a Design element to be the centre of interest of the view. The origin of the selected Design element will be positioned at the centre of the view. Cursor displays the Point Construction Option Form and ask you to select a point with the cursor to become the centre of interest of the view. By Cursor displays the Point Construction Option Form and ask you to select a base point and displacement with the cursor to move the centre of interest of the view. Explicitdisplays the User Defined Centre Position form which enables you to enter co-ordinates for the centre of the view.

View > Offset

Sets the position of the centre of the VIEW contents, relative to the centre of the VIEW.

View Creation

5-8

Setting the Contents of a View

The Graphics form menu enables you to create and modify Drawlists 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. Drawlists are independent of the views, therefore, 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, depending on the set-up by the Draft Administrator. Selecting Graphics>Drawlist from the form menu displays the Drawlist Management form:

The Drawlist Library scrollable list gives a list of the available Drawlist Libraries.

View Creation

5-9

The Drawlists window is a scrollable list of all the Drawlists available within the selected Drawlist Library. In the example above only the default drawlist, created automatically during Drawing creation is shown. The Reference List Members window displays: If Design Members is selected from the scrollable list, the available Design elements in the Design database, governed by the MDB you are using, will be displayed. If Drawlists is selected from the scrollable list, the available Drawlists will be displayed. If Lists / Collections have been previously defined then they will be available for selection. If no List/Collection has been defined, or you wish to create a new one, clicking the Lists button will display the List/Collection form. Having defined a new List/Collection, clicking the Update button will display all defined Lists/Collections in the scrollable list for selection. The Drawlist Members window displays the Design elements or Drawlists that have been selected to be members of the current Drawlist. In the example above, no members have been selected yet. 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) element 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) element in the Drawlist Members window. For example, all equipment except /1301 may be required to be displayed in the view. Rather than adding each piece of equipment separately, the zone /EQUIPMENT may be added and the specific piece of equipment /1301 subsequently removed from the Drawlist.

View Creation

5-10

The Navigation form menu offers an alternative method of navigation. The options are the same as those available from the Navigation pulldown menu of the Members list. Note: If the Members list is displayed, it will be removed while the Draw List Management form is displayed. The buttons to the right of the Drawlists window control the creation and deletion of Drawlists: Create creates a new, empty Drawlist. Create Copy creates a copy of a Drawlist selected from the available Drawlist Libraries . Delete deletes the currently selected Drawlist. Clean-Up removes any Drawlist Members will Null or BAD references. The Delete Entry and Delete All buttons at the bottom right of the form delete the current highlighted entry from the Drawlist or all Drawlist members respectively. The Volume Defined and Limits buttons at the bottom right of the form enables the addition of all elements that are positioned wholly within a defined volume. Clicking the Limits button will display the Drawlist Limits form:

View Creation

5-11

The limits are set by entering appropriate co-ordinates for opposing corners of the limits volume. After setting the limits clicking the Volume Define button adds all elements wholly within the entered co-ordinates. If required, the Remove or Delete Entry buttons may be used to amend the Drawlist. Selecting Graphics>Drawlist Ref from the form menu displays the Drawlist Reference form:

This form enables you to point (reference) the current view to a Drawlist so that the Drawlist Members are displayed in the view. It should be noted that a view may only reference one Drawlist. The Options scrollable list allows the owning Sheets or the owning Drawings Drawlist to be used. The VIEWs current Drawlist may be used, or the Drawlist reference may be unset. The Drawlist Library scrollable list allows you to choose from a list of Drawlist Libraries, as set up by your Draft Administrator. The Drawing selection, as shown above, 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 you to check the contents of the Drawlist you have selected. The Modify button displays the Drawlist Management form enabling you to modify or create a new Drawlist as described previously.

View Creation

5-12

Setting View Attributes

Having set the frame size and position, the centre of interest of the view and the Drawlist Reference the way the Design elements are displayed in the view may be changed by modifying the view attributes. It should be noted that it is not compulsory to set any of the attributes described in this section, although in practice the view scale, using the Nearest and Auto Scale buttons, will need to be set as a minimum. If any attributes are changed, the Apply and a Update Design Radio button must be clicked before any changes will be observed on the display, with exception of scale, which only requires a Update Design to be performed if any part is overlapping the view border or the view has lines missing. The view attributes are: Title If you wish to give the view a title then enter an appropriate title in the text box. This sets a simple text attribute that can be used later for view annotation. View Type This scrollable list gives the available hiddenline drawing representation options. Each option gives a different degree of hidden line removal from Wireline to Universal Hidden Line. See Appendix A for examples of the different representations. Wireline gives a conventional wireline picture showing all element and Ppoints. This option is the quickest to generate the view graphics. Modelled Wireline gives slightly greater realism by blending the intersection of primitives, but without incurring the computational overheads of removing hidden lines. Local Hidden Line representation gives a picture where hidden lines are removed from Equipments. Where two or more Equipments overlap the elements overlapping are shown in wireline. Global Hidden Line representation gives a picture where all hidden lines are removed.

View Creation

5-13

Universal Hidden causes intersection lines between significant elements (e.g. EQUI and STRU, SUBS and BRAN) to be generated. This option is the slowest to generate the view graphics. Section Mode has two options: Standard This option sections all Design elements where appropriate. Omit Fractional Pipe Components This option removes any partial pipe components from the display that result from a section being applied. Style This scrollable list gives the available Representation Rulesets (RRST) elements that are used to control the display representation of the different types of the Design elements within the view. Representation Rulesets are created by the Draft Administrator. Hatching Rules This scrollable list gives the available Hatching Rulessets 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 This scrollable list gives the available Change Rulessets that are used to control the appearance of changed Design elements and annotation on subsequent updates of the drawing. The use of Change Rulesets is covered in M20 Advanced Drawing Production. Direction The required view direction may be selected from the pull-down list of pre-defined directions, which include the four standard Isometric views. Alternatively, a view direction, e.g. N 45 E, may be typed into the text box. The Derived button will prompt you to identify a design element in the Graphics area for setting the view direction. Auto Scale This sets the view scale such that all of the design elements in the Drawlist will fit just within 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. Nearest It is unlikely that Auto Scale will produce a standard scale for the view. Clicking the Nearest button will select the nearest available standard scale, as defined by the Draft Administrator, and set it. The standard scales can also be selected from the scrollable list next to the Nearest button.

View Creation

5-14

Although the principal view attributes are set from the main body of the User-Defined View form, additional attributes may be accessed by clicking the Attributes button to display the User-Defined View Attributes form:

Graphics Angle controls the angle of the design graphics within the view. A positive angle gives an anti-clockwise rotation. The view direction remains the same. View Orientation controls the orientation of the view and its 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 its contents to be rotated through 270 degrees. Arc Tolerance controls the difference between the true and the facetted representation of curves of the graphical output for the view, being 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 A value of 0 gives a parallel view. The value is related to the view angle. Gapping controls the gap (in mm) inserted in view lines crossed by other lines such as centrelines, Plines, etc. Note line Pen options control the appearance of the view frame (assuming it is visible). The value set will also be cascaded down to any Layers subsequently created as members of the view. The Note line Pen may be one of the standard pens or a user-defined pen set-up by the Draft Administrator.

View Creation

5-15

Using Predefined Frame Configurations User-Defined views may be created from a set of predefined view configurations Selecting Create>View>Predefined Frame from the General menu displays the View Configuration form:

The central area of the View Configuration form shows diagrams of view layouts on the Sheet. Clicking the radio button next to desired configuration selects that layout. Having selected the desired configuration, the appropriate view directions lists will be populated with the default view directions for that layout. If you wish to change the given view direction, select the new direction using the pull-down list. The value in the View Spacing text box is the distance (in mm) between each view frame and may be changed as required. Having clicked on OK, the required number of views will be created in the active area of the sheet. The Title of each view will be set to correspond to its view direction.

View Creation

5-16

Exercise 6 Creating Views Create a new Sheet, Explicitly, of any size but without a backing sheet and create a single User-Defined view, do NOT use the Predefined Frame option. Experiment resizing and moving the view using the User-Defined View form Frame menu options and Modify Mode. Finish by making the view occupy the top left quarter of the Sheet. Create another User-Defined view and resize it using the Frame>Copy Size options on the User-Defined View form menu. Use the Frame>Align options to align the view with various edges and axes of the first view. Create a third and fourth view by copying one of the other views using the options available on the top bar menus. Create a Sheet using the Template option, move and resize the single view created by the template and add two new views to the Sheet. Delete all the views from the Sheet created above. Using the Predefined Frame option, create four views with viewing directions of North, East, Down and Iso3 view respectively and a View Spacing of 10mm. Note that the predefined views only occupy the active area of the backing sheet. Using the Graphic > Drawlist, add the STABILISER Equipment Zone to the Drawing Default Drawlist. Using Modify > View > User-Defined for each view set:

View Type to Universal Hidden Line Section Mode to Standard Style to /DRA/PRJ/REPR/GEN/BASIC Hatching Rules to unset Change Rules to unset The Drawlist Ref to the default Drawing Drawlist

On the User-Defined View form, for each view, click the Auto Scale button followed by the Apply make sure that the Update Design Radio button is set. The views should now display the STABILISER equipment in all four views.

View Creation

5-17

Revisit all views and select a suitable standard scale that will suit the 3 orthogonal views Select Modify>Drawlist... from the main menu to display the Drawlist Management form and amend the default Drawlist by removing the equipment C1101 (i.e. C1101 is a REME element). Update the view graphics by selecting Graphics>Update>Design from the main menu. Note that C1101 has now been removed from all four views. Create four new Drawlists, i.e. one for each view, with different elements of the STABILISER model in each Drawlist. Modify the Drawlist Ref for each view to point to a different Drawlist and Update Design for each view. Using the Sheet /DRG_1/SHT_1 that you created in Exercise 1, create a single User-Defined view with a viewing direction of Down. Add all of the STABILISER equipment to a Drawlist and set the Drawlist Ref to it. You will use this Sheet in subsequent exercises.

Populating the 2D View using a 3D Design View

6-2

The 3D View Window in Draft allows you to assemble and manipulate Design elements to populate drawing Sheets. This allows you to examine the content of the drawings in 3D view, before finalising the view content as a 2D drawing.

The main Draft display shows the Drawing Sheet /DRG_1/SHT_1 which we created in the previous exercise, it was displayed using Open Sheet from the shortcut menu on the sheet selection (RH Mouse Button On Draft Explorer).

The 3D display is selected using Display>3D View from the main menu (or select 3D View from the shortcut menu in the 2D View).

The 3D View window appears, displaying the item you selected. For example:

Note: The View positions have been re-arranged from the Draft Default.

The main features of the 3D View

The Display controls. These allow you to display the list content, add selected components to the 2D View Content list (see below), and remove all items from the list.

Show View Content: This toggles between displaying the 2D View Content list, and hiding the display.

Add to View: This adds elements to the 2D View Content list and the 3D View. The element added is usually the current element, unless there is an active multiple selection (in which case the entire selection is added). Added elements are displayed in the colour specified by the representation rules

Remove from View: This removes elements from the 2D View Content list and the 3D View. The element removed is usually the current element, unless there is an active multiple selection (in which case the entire selection is removed).

The Section Plane controls to the right of the above controls are detailed in Session 10.

The View Content list shows the elements which have been added to the 2D and 3D Views in Draft. To remove an item from the 3D View, select it in the list and select Remove Selected from the shortcut menu.

The Update controls update the 2D View with any changes that are made to the Design database (which will be shown in the 3D View).

The Update the 2D View Content when adding from the Design Explorer check box. When selected, any element added or removed from the 3D View from Design Explorer is automatically amended in the 2D View Content List. This is displayed in the 3D View by the appropriate representation colour. If this option is not selected, any addition or removal of an element affects the 3D View only, and the 2D IdList is unchanged. In this case added items are shown in grey. Therefore, the colour of items displayed in the 3D View indicates their status; grey items are in the 3D View only and not in the IdList (and therefore will not be recognised by an Update Design), whereas coloured items are in both the 3D View and the IdList.

Update 3D View from 2D View: This displays the contents of the 2D View in the 3D View.

Pick 2D View to associate to the 3D View: This allows the current 3D View contents to be associated with a different 2D View. When using this tool you are asked to identify a 2D View to associate with the current 3D View contents. This functionality is particularly useful whenever you require different views of similar content

Scale Control

This allows you to enter a view scale directly, or to input a scale via the Scale form (click on the ellipsis). Any changes to scale are reflected immediately on the display. This option allows you to scale the Frame to the drawing. The Scale form allows you to:

Choose whether the scale is shown as a numeric ratio (Metric), or in Architectural or Engineering styles.

Instruct Draft to calculate a scale so that the elements in the drawlist will just fit within the View, using the Auto Scale button. The actual scale will be displayed in the Scale text box.

The scale of the drawing is set by Clicking on the ellipsis:

Select Auto Scale to allow Draft to automatically select a scale for the view. Select Nearest to instruct Draft to find the nearest standard scale to the calculated value. The View size will be changed accordingly, and the new scale factor will be shown in the text box.

Manipulating the 3D View

You can manipulate the 3D View using the functionality contained in the 3D window. The View Manipulation Buttons and the Information Bar are the standard design options. You can control how the design model is shown by using the options on the 3D View shortcut menu with the mouse pointer in a 'blank' area of the main display window, or by using the 3D View menu options from the Main menu. The Section Planes buttons to access section planes functionality as described in Session 10. The Viewfinder (the magenta box) can be interactively resized, repositioned and rotated. Resize and Rotate changes made to the Viewfinder give equivalent changes in the 2D View. The Viewfinder is detailed in the Draft online help .
