This lesson is the text portion of the video called Lesson One. This lesson covers all that you will see in the video, step-by-step. It is a written roadmap you can use to work your way through the exercise. I recommend you play the video for a while and watch the first part of it. Then pause it and do the step-by-step instructions in this lesson. You can then go back to the video and repeat the process. If you need to look at something more than once, you can always replay the video through that section. That’s the great thing about having a video to replay: you can clear up any part of the lessons that you may have questions about, and you won’t have any aspect of this course that you won’t understand. So start the first video, and after a few minutes pause it. Then do the steps that follow. Good luck – and congratulations! You’re on your way to Mastering CADWorx Plant Professional Software!

23


Put it 100 from the end of the flange. See illustration which follows.

•

Placing the other branch

Your drawing will now look as shown.


24


Running a Continuity Check At this point it would be good practice to run a continuity check. This insures that the components you’ve placed in the drawing are connected correctly.

•

Running a Continuity Check

•

Continuity Checks should be run on each line as a standard procedure

•

This insures that you will produce correctly drawn piping models and drawings

To run this check: 119. 120. 121. 122. 123.

Click Plant Click Utility Click Continuity Window the drawings and press Type: 300 (to have the system show the ends of the pipe runs and branches with a 300 diameter circle). 124. Press (for the 0.0010 precision).

Your drawing should look as shown.


25


Your drawing should look like the previous figure. The circles indicate that a piping run has started and stopped. They also will appear at the start points and end points of any branches (like the thredolets). If you have additional circles appearing in the middle of the runs, this indicates an incorrect gap or an overlap between components. This can be caused by not pressing , as you connect one component to the next, or not having a good OSNAP connection between components.

•

Extra circles that occur during the middle of a piping run, instead of at the ends, indicate errors

•

All continuity errors must be fixed before proceeding with the drawing

•

A failure to fix continuity errors will cause problems in generating isometrics, and possibly give errors in material lists

These errors must be corrected before continuing on, since they will cause problems with the isometric drawing you will be generating soon. If you get extra circles, zoom into the area and take a close look. Click on the circles and light up their grips. You will either see gaps between centerlines, places where gaskets are placed incorrectly (not positioned right between flanges, but actually partly inside one of the flanges), or overlapping centerlines. All of these errors will cause an extra circle to appear in a pipe run where it is not expected. Here are some examples

Overlapping centerlines

Centerlines with gaps

Valve not placed correctly against gasket


26


Line Numbering 125. Click the Line Number Setup Tool Button.

This brings up the Line Numbering System Dialog Box.

•

Starting the Line Number Setup command

By default, the system uses Size-Spec as its line number. You’ll change that now, to a different line number format. Your line number will be Size-Service-Count-Spec.


27


Setting up the Line sequence. 126. Click the down arrow under Category. •

Setting up the Line Numbering sequence


28

127. Click on Service, and click Add.

•

Adding the other categories that make up the line number

130. Click in the area under Separator, and type in a dash (hyphen). 131. Click Add. 132. Click Add again (two dashes are added to the line number list).

Now, you’ll arrange the line number to be Size-Service-Count-Spec.


29


133. Click on the word Service, to highlight it. Click on the Move Up button to move it up in the list, below Size.

134. Click on the word Count, and move it up to be below Service. 135. Click one of the dashes in the list, to highlight it, and move it up between Service and Count (use the illustration, or the video to see what’s being described). 136. Continue to Move up the dashes, and the Size/Service/Spec categories as needed to set up a line number list as shown. 137. Click OK when done, and Save the drawing at this point. 138. Click on the Line Number Setup tool button again to open the dialog box. 139. Click Service, and in the “Default value” area, highlight the word Service and type in LH . 140. Click Count, and change it to 1000. 141. Click OK to exit this dialog box.

•

Setting the values for the fields in the line number


30


Updating the Line Number in the Components 142. Type: Nba (for Line Number Assign) Note: A list of CADWorx commands that you can type in can be found by clicking Tools (pull down menu), Customize, Edit Program Parameters. The file will open in Notepad, and you can see all the commands that can be typed in. The CADWorx commands are toward the bottom of the file.

•

Embedding line numbers in all the components

•

Verifying the line number has been updated

143. Select everything in the drawing, and press . 144. Type: A (for “All”). This will assign the new line number to all of the components. To verify: 145. Double click one off the Gate Valves in the drawing. You’ll get a dialog box showing the new line number assigned to the valve.

Click OK to exit this dialog box.


31


Annotation (Dimensions, Bill of Materials, Line Number labels, etc.) - Paper Space or Model Space? You can dimension the drawing and add labels to it either in Model Space or Paper Space, depending upon your preferences and also the job requirements. When you do 3D Modeling, you will typically use Paper Space for these tasks, since it lends itself so well to working in 3D.

•

Moving the drawing over in the border area

•

Selecting the Automatic Dimensioning option

In this example, you will place the dimensions and annotation in Model Space, and later you will be shown both methods. 146. Move your drawing down into the Border as shown. (Leaving room on the right for a Bill of Materials).

147. Click Plant 148. Click Dimension 149. Click Automatic


32


150. Right click on the mouse and type: 675 (This sets the dimension lines 675mm away, to scale, from the objects. 151. Click a point, as shown, in the center of your pipe drawing.

•

•

Placing some Graphic Labels

169. A dialog appears with Head highlighted. 170. Click OK

171. Click a point on your drawing under the piping drawing to place this Plan label. 172. Drag the mouse to the right and click (for orientation), or you could also Type: 0 , to orient the label at 0 degrees. Either way is fine. 173. Type 1:20 , and the label will appear. 174. Save the drawing at this point.


37


Line Number Annotation

•

Placing some Graphic Labels

•

Annotating (labeling a Line Number)

•

Placing a line number label in vertical

186. Place another Line Number label on the vertical segment, on the left. To tell the text to go up and down, you will need to type 90, for the rotation angle, or drag the mouse up toward the top of the screen and click. You can see this in the video.


39


Component Annotation Next you’ll label a couple of the fittings. 187. 188. 189. 190. 191. 192. 193. 194. 195. 196.

Click Plant Click Text Click Annotate Click Component Press (for Short Annotation). Click the 6”x4” reducer in the top left area of the drawing. Right click on the mouse and Click Leader Click a point where you want the text to start. Use the Grip on the text to drag it into position like you want it to look (see the video for how this works). 197. You can also use a Grip to move the arrowhead of the Leader where you want it to point (on the edge of the reducer).

198. Repeat for the 6”x3/4” Thredolet at the bottom left of the drawing.


•

Annotating components

•

The annotation text height matches the dimension text height.

•

If you want to make it smaller, you will have to change the dimension text height (in Format, Dimension Style)

•

You can also annotate the components without using the Leader option, and draw your own Leader later. This will give you smaller text as well

CADWorx® Video Training Series Lesson Two - First Look at 3D

Lesson Two 3D – First Look Some topics covered in this lesson: You will learn how to…. • •

Use the AutoCAD View Ribbon and Tool Bar Convert CADWorx files from 2D to 3D

• •

Work with the CADWorx UCS Tool Bar Model components in the Vertical Plane

Note: Valve Operators (hand wheels) will be modified to correct sizes in a later part of the lesson


42


1. 2. 3. 4. 5.

Start CADWorx, and open the Lesson_One drawing. Click File, then Save As Type: Lesson_Two (do a Save As, Lesson_Two). Erase the Border, Bill of Materials, and Dimensions Save the drawing again.

Opening the AutoCAD View Tool Bar 6.

If you’re using AutoCAD 2009, you can set your Work Space to 3D Modeling. In that Work Space you can access the various 3D Views easily (see video). 7. For 2008 and earlier versions of AutoCAD: 8. Move the cursor (pointer) over any AutoCAD (not CADWorx) tool button. 9. Right Click on the mouse. 10. A list of AutoCAD tool bars will appear. 11. Click on the View toolbar (if it dos not already have a check on it. If it has a check on it, it is already open).

12. 13.

Drag and dock the toolbar in the top area of your drawing. Click on the SW Isometric tool button.

CADWorx has the capability to display its components in 2D, 3D, or Single Line graphics. When you first open the drawing, you will be viewing it in 3D. If you want to have part of the model display in one of the other modes, you can use the Settings tool bar to change it.

•

Opening the Lesson One drawing

•

Saving under a different name

•

Using the 3D Modeling Work Space (AutoCAD 2009), or Bringing up the 3D View tool bar (AutoCAD 2008 and earlier)

•

Setting the view to the South West


43


14.

15. 16. 17. 18. 19. 20.

21. 22.

Next you’ll place the Settings toolbar at the top of your screen, next to the AutoCAD View toolbar you placed there earlier. Click Plant Click Toolbars Click Settings Drag it up next to the view toolbar in the top area of your screen. From the Settings Tool bar, hold down the mouse button on the 2D button, and you’ll see the tool bar has a “fly out.” Move the pointer down to the “2D, “Single Line”, or “Solids” button and release.

•

Seeing the drawing in different display modes (2D, Single Line, 3D)

Click two points to Window all the objects, and press . The components will convert to the mode you selected. Convert the model back to 3D solids. Note: The valve operators (called Top Works) are sized in this first model based on a file the system uses. As the lesson progresses, you’ll specify a different top works file so they come in as typical sizes for gate valves. Also, you’ll see how to model them manually if you are using a version of CADWorx that is 2008 or earlier.


44


23. 24. 25.

•

You’ll change the display to show the model in 2D wire frame, shaded as conceptual shading, and also as single line grapics

•

Wireframe takes less system resources

•

Bringing up the CADWorx UCS toolbar, which will greatly simplify 3D modeling

Click View Click Visual Styles Click Conceptual They system will shade the objects.


45


26. 27. 28.

Click View Click Visual Styles Click 2D Wire frame When working in 3D, it is a good rule to work in 2D Wire frame. It is less taxing on your system’s resources, and you’ll have better machine speed if you do so.

29. 30. 31. 32. 33.

Watch Video Two and Video Three, which discuss the Top Works feature in CADWorx. Bring in the CADWorx UCS Toolbar – Click Plant, Toolbars, UCS. Doc it at the top area of your screen. Zoom into the area near to first flange and reducer, on the left of the drawing. What you’ll do next is work in the vertical plane. The two olets, nipples and threaded gate valves were constructed earlier in the horizontal plane.

•

Discussing 3D versus Isometrics

•

Rotating the UCS, which rotates the crosshairs

For this exercise, you’ll erase them, and then you’ll redo them in vertical, like they would actually be if this was a suction line on a pump. 34.

Erase the two thredolets, nipples, and gate valves. What you’ll do next, is place a drain for the line. It will again consist of a thredolet, a pipe nipple, and a gate valve, but it will be placed this time in “vertical”. To place it in vertical (coming down) the crosshairs have to be flipped on edge, sort of like doing an isometric drawing. When you draw Isos, you have to flip your crosshairs into the different planes you draw in: top plane, vertical left plane, vertical right plane. The same is try in 3D modeling. You have to flip your crosshairs into the proper planes to place CADWorx components going up and down in the “Z” direction.


46


The CADWorx UCS tool bar makes this easy. Using this toolbar, the “UCS” toolbar from CADWorx (not the UCS AutoCAD toolbar – they are different) it has the same look and feel as doing isometric drawings. •

Setting up the UCS to work in the vertical plane

•

Setting the size and spec

•

Modeling a thredolet

•

Using tracking to position the thredolet along the pipe

The UCS Next button 35.

Look at they UCS icon in the lower left area of your screen. You are currently in the “World Coordinate System”. You can tell that by the small square where the three axes meet.

36.

Click the UCS Next button (see illustration above)

37.

Notice how your crosshairs change to work in “vertical right”, and the UCS icon changes as well. This is how you need to be set to add the drains to the lines.

38.

Click on the “Main Size” area in the tool pallet.


47


39. 40.

Set the Main Size to 6”. Set the Reduction Size to ¾”.

41.

Click on the Thredolet button.

42. 43.

Have the OSNAP, Tracking, and Polar buttons turned on. Move the crosshairs over the end of the pipe and pause them (don’t click). You need to be right over the center of the pipe, at its end.

The system will generate two drawings

In this first example, you will use the Metric_Inch_A2 Style (drawing border). So select it from the list, if it is not shown. Click OK. Press (to select components). Window all the items in the drawing and press . You will get a CADWorx Isogen Results dialog box.

In this instance, the system shows it has generated two isometric drawings. It did this because if it put everything on a single isometric, the drawing would be too crowded. By making two isos, it is able to produce two drawings with a nice appearance.



Note: If you get more than two isos generated, please see the video for possible causes. 10. 11. 12.

Click the Open Plot Files button, and take a look at the isos. Now run the isos on the A3 border, and also the A1 border. Notice how the A1 border shows all the information on a single sheet. Note: Some clients generate their isos on a A1 border, and then plot them half-sized.

If you were doing production work at this time, you would probably have an administrator set up the job’s borders for you. If not, you could always erase the current border and insert your client’s border, then save the drawing in the directory needed for your job. In a later lesson, I will show you how to set up an Isogen project, so you can see how all of this is done and customize it for your particular job.

CADWorx® Video Training Series Lesson Four 3D Modeling

Lesson Four 3D Modeling In this lesson you will learn how to: •

Easily Rotate the UCS to model in different planes

•

Model lines in a method similar to drawing isometrics

•

Create 3D Router Lines

•

Automatically place elbows and pipe segments

•

Generate Clipped Views using the CADWorx Viewbox command

•

Annotate and Dimension in Paper Space on a Layout

In this lesson you will construct three lines that are connected to exchangers and a vessel. You’ll see a couple of ways these can be modeled: manual placement and using router lines. Both methods are effective, and the choice depends upon the geometry and information you have to work with. Generally speaking, a Router line is going to give you the fastest tool for constructing lines in 3D compared to other methods. First you’ll model the return lines, from the top of the exchangers going back into the vessel. 1. 2.

3. 4.

5.

Start a new drawing, using a template: Metric. Click File, Click Save As Browse to the C:\CADWorx_Video_Training\Lessons folder. Save the drawing as 12-CPRA_B-1004-150_M.

11.

You will see your two XRefs now appearing on the drawing.

12.

Depending upon your AutoCAD version, you can use the 2009 3D Workspace and work your 3D views directly off that. For this lesson, bring up the AutoCAD View tool bar, if it is not already on your screen (this method works with all versions of AutoCAD). To do this, you can move the mouse pointed over any AutoCAD tool button, and Right Click on the Mouse. A list of tool bars will appear, and then you select the View Tool bar (2008 version illustrated).

13. Dock the View tool bar at the top area on your screen. 14. Click on the South West Isometric View.

•

Getting an overview of what’s to follow

In this lesson, you will be modeling the two lines that return from the top of the exchangers into the vertical tower.


64


17.

This will be a valuable lesson for you, because you will see a couple of different approaches to modeling these lines: placing fittings one by one, and also how to use a Router Line. The first thing to emphasize in the lesson is that modeling in 3D using CADWorx is easy. The developers of CADWorx have made 3D modeling as easy as doing a 2D Isometric drawing. Do you remember how, in doing an isometric, you flip the crosshairs from one plane to another using the F5 key on the keyboard?

•

Isometrics – the traditional way to work

•

It’s a short step from Isometrics to working in 3D when using CADWorx

When you pressed the F5 key your crosshairs would rotate into the top plane, or vertical left hand plane, or vertical right hand plane. Do you remember how easy that is? It’s a fast and easy way to do a pictorial drawing. Pressing the F5 Key flips the crosshairs in Isometric.

Well working with CADWorx in 3D is very similar! Modeling in 3D in CADWorx has the same look and feel as creating a 2D Isometric drawing! If you think of it like this, then 3D modeling in CADWorx is a breeze!


65


Instead of the F5 key to rotate your crosshairs, CADWorx uses their own UCS Toolbar, which does a similar function. 18.

19. 20. 21. 22. 23. 24.

Now you’ll bring up the CADWorx (not AutoCAD’s) UCS tool bar (2008 version illustrated)

Click Plant (at the top of the screen) Click Tool Bars Click UCS The UCS tool bar will appear. Dock it in the top area of your screen. Notice how your crosshairs are oriented. Click the UCS Next button a few times, and notice how your crosshairs rotate. It looks very similar to how crosshairs rotate when you do isometrics!

Now you’ll test this to get a feel of how this works. 25.

Click the UCS Next button until your crosshairs are in the “top” plane. In 3D, you call this the “Flat” plane.


66

•

Switching planes in 3D seems similar to flipping the crosshairs in isometric

•

In 3D, you click the UCS Next button to rotate the crosshairs (similar to hitting the F5 key on the keyboard when you did isometrics)


Next you’ll set up your system to draw some test lines to see how this works. 26. 27. 28. 29. 30.

Click Plant Click Setup Set the Main Size to 6”. Set the Specification to 150_M. Set the Drawing Mode to 3D.

31.

Pan the screen to the side, so that you are in a clear area. You will now draw a few fittings to get a good look at this.

32.

Make sure you have ORTHO turned on.

42.

Now you’ll turn draw another elbow turning up in the vertical plane.


68


43.

44.

Click on the UCS Next button on the UCS tool bar.

Now you’ll draw some components in vertical.

47. 48.

Rotating the UCS easily into the “vertical right hand” plane

•

Modeling in 3D has a similar look and feel to creating Isometric drawings

Your cross hairs should look as shown. If not, keep clicking the UCS Next button to get them set.

Do you see how this is going to let you draw in the vertical plane? You can see how the X Y Plane is oriented in the “vertical right hand plane” (it’s on edge going up and down, instead of “flat” like you normally see it). When you draw with the UCS tilted like this, your components will be drawn in the vertical XY Plane. 45. 46.

•

Click Elbow Press on the keyboard, to have the elbow connect automatically to the last piece of pipe. Drag the mouse toward the upper right direction and click. Drag the mouse straight up and click. You’ve just drawn an elbow going up.


69


49. 50.

Click Pipe and press on the keyboard. Drag the mouse straight up and Type: 1800mm .

•

Do you see how this is just like drawing a 2D isometric, but it’s really in 3D? Modeling in CADWorx Plant Pro can get really fast and easy, once you get used to it. 51. 52.

Click the UCS Next tool button on the UCS tool bar. Set it as shown.

53. 54. 55. 56.

72

Inserting components into a line and having the system “break out” the line as they are inserted


So you can see that modeling in 3D in CADWorx is a matter of setting your crosshairs (UCS) in the plane you want to work, then simply placing components. There’s also a great tool which you’ll do soon called a ROUTER LINE, which together with the method you just practiced, will have you creating 3D CADWorx models very fast and efficiently. 71.

Erase the lines you just drew. It was just to illustrate how to model in 3D. Zoom back into the area near the top of the exchangers. Now you’ll model lines coming out of the top of the far exchanger.

•


73

Getting set for modeling


72. 73.

Set the Main Size to 12”. The spec should be set to 150_M. Click the Line Number setup button in the top area of the CADWorx tool palette.

74. You need to set the line number to include Size, Service, Count, Spec, and Insulate. You can see the video or lesson one if you need to review how to set this up.

•

75. Your line number will look as shown. You will use CPRB for the Service, and 1004 for the count. The Insulate value will be nothing, since we don’t want to show insulation for this line.


74

Setting up the line number


76.

Click the UCS Next button as needed to orient your crosshairs in the vertical left hand plane. Note: The Z direction is not important here unless you want to place some text in 3D in the model. The X and Y are what’s important to us here. •

Adding Annotation to the Drawing in Paper Space “Live” Views or “Flattened” Views? In this lesson you will annotate the orthographic views in Paper Space. This is the recommended method for producing drawings from a model. There are two options you can choose from when you create your drawings in a Layout (in Paper Space). One option is to have viewports with views of the model in them, as you have just created. These are “live” views, because if you change the model, your views will update. Also you will see how to dimension them so that the dimensions update as well, if the model changes.

Adding Dimensions in Paper Space You can use Associative Dimensions in Paper Space easily. These dimensions will all have the same height and give the proper distances, no matter what scale or zoom factor you’ve set the viewport for. 374. Type: Dimassoc . 375. Type: 2 . This sets the Dimension Associate system variable to 2. AutoCAD will know to dimension distances properly in Paper Space with this setting. You must use OSNAP on Model Objects (objects within the viewports in Model Space) for this to work properly.


119


376. Using the video as a guide, add the dimensions and labels as shown.


120


You can also make a 2D Representation of a 3D view. This allows you to “flatten” a 3D view into a 2D view. Sometimes clients only want to receive 2D deliverables. Experiment with this command, following the prompts if you need to utilize this feature.

CADWorx® Video Training Series Lesson Five Using 3D Routers

Routing Lines in 3D using the Router Command

Routers are a great tool in CADWorx Plant Professional. They allow you to “route” centerlines of piping runs in 3D, and then have the system automatically place elbows and pipe segments along the routing line. The Router command also has a number of options to it which make modeling in 3D even easier. For instance, you can tell the system to route your piping using a Bottom of Pipe elevation, or you can have the system Slope the line. If you route a Rolled Offset, the system will automatically Trim the Elbows for you as well.


122

Press and Click OK to exit the command. CADWorx has just built a CAESAR II file that can be read directly into CAESAR II for analysis! This file will come into CAESAR II with the geometry fully done, and nodes numbered correctly. This saves a tremendous amount of time for the stress engineers, since they can start to analyze the line without having to create all of the geometry.


133


Once the stress engineers have analyzed the line, they can save the file with any changes made to it. Perhaps they added additional supports to it, or added an expansion loop. If changes were made, you could then go to the pull down menus (Plant, Accessory, CAESAR II, System In) and bring the modified line back into your model. The system would automatically update your model with the engineer’s changes.

•

This bi-directional information exchange makes CADWorx and CAESAR II a very powerful combination of software to do project work. 80.

Save your line again, and close the drawing.


134

The CAESAR II bidirectional interface will save the stress engineers a great deal of time, since the geometry will come directly from the model as a CAESAR II input file

CADWorx® Video Training Series Lesson Six Productivity Tools

Lesson Six Productivity Tools

This section will cover a number of topics: • • • • • • •

Exporting a CADWorx® line into CAESAR II for analysis Generating custom components in CADWorx® Modeling Cable Trays Working with Databases in CADWorx® Checking data in the CADWorx model compared to the P&IDs Using Xrefs effectively Introduction to Sheet Sets

As these topics begin to get implemented in your work process, you will find your productivity steadily improving. Depending upon which of these you use, you should find that you start having less duplication of effort, or better communication, or less cross-checking.

Exporting and Importing back a line between CADWorx and CAESAR II CADWorx has the ability to export a line out to CAESAR II pipe stress software. The line will export out with full and correct geometry. CAESAR II can then open it up seamlessly, and the design engineer can then analyze it for code compliance. During the analysis, if the engineer modifies the geometry of the line, the changes can be imported directly back into CADWorx and the model updated. The following section illustrates how this works.


169


In this example you will export out this line to CAESAR II.

1.

2. 3.

Open the drawing: 8”-LH-1012-150_M. You can find it either in the Examples folder or the Lessons folder (under C:\CADWorx_Video_Training\). Once the drawing is open, you can click: Plant, Accessory, CAESAR II, System Out

•


170

Exporting this line out to CAESAR II


The system will export the line out into a CAESAR II format with a .c2 file extension.

•

4. 5.

6.

Click Save Select the components to be exported, and press . (Note: You can isolate a line beforehand if needed using the CADWorx line isolate command). Press (you will not specify start locations). The system will proceed and write out a CAESAR II input file for you.


171

The system will build a complete CAESAR II input file


7.

Click OK to finish the export. At this point you have a completed CAESAR II input file. All the geometry of the line will be modeled correctly, and viewed quickly within CAESAR II.

To illustrate this, below is how the line looks when it is opened in CAESAR II.


172

•

Opening the file in CAESAR II


When the view is zoomed in closer in CAESAR II you can see how the nodes are numbered and the restraints (supports) are modeled.

It’s easy to see how this can impact your productivity gains in 3D CAD modeling. When you can cut out the duplication of effort for the engineer to recreate the geometry, great time and cost savings will result. As a final part of the process, if the line is modified in CAESAR II, then the file can be saved and imported directly back into CADWorx. So the geometric and design data makes the round trip seamlessly.


173

•

The CAESAR II file has the supports and nodes all set up

•

If the line is modified in CAESAR II, the changes can be imported right back into CADWorx and the model automatically updated


Creating Custom Components CADWorx allows you to create your own special components in an easy to use procedure. In this lesson you’ll create the Flame Arrestor shown below.

Working with Databases in CADWorx

CADWorx has a number of options you can use when it comes to databases. For instance, it can: • • •

Run without a database Export out intermittently to a database Run connected to a live database.

•

CADworx has many options when it comes to databases

•

You can run with or without a live database

•

CADWorx supports Access, Oracle, and SQL Server

•

A Bill of Materials is a list for a single drawing

So these choices are typical of CADWorx – you can work the way that best suits your needs. Databases are used for several reasons: • • •

Using databases you can produce a global material list for a project that is composed of multiple drawings. You can also change descriptive information in a database, and have it update the model. Also, you can compare data in a P&ID data table to data within a 3D piping model.

CADWorx supports three Database systems: • • •

Access SQL Server Oracle

Generating a Bill of Materials A Bill of Materials is a material list for a single drawing. It can be contained in the drawing, or exported out to Excel, Htm, Mdb, or as a Txt file.


188


To setup a Bill of Materials 1. 2. 3.

Click Plant Click Bill of Materials Click Setup The Bill of Materials Setup dialog box will appear.

This dialog lets you add new columns to the BOM from a list of various data items. You can set the width of the columns, the headings, their location in the BOM, etc.

•

The BOM is easily set to look the way you want it to look


Exporting Component Data out to a Database CADWorx has the capability of exporting component information out to a database on an intermittent basis. If you don’t want to run the system with a live database, but you still want to obtain a global material list, you can use this option. This gives you a lot of flexibility. To export component information out to a database: 1. 2. 3. 4.

Click Plant Click Accessory Click Database Click Export

•

5. 6.

Press (to select components) Type: A for all. A dialog box will appear for you to select the database type.

7.

•

Choosing to use a new Access database

•

CADWorx lets you append and synchronize the database whenever you like

Following the video, set up a database like it shows. At a later time, if you export again to the database, it will prompt you to Append/Synchronize. This allows you to update and synchronize the database with the various drawings you have in your project.

Working with a Live Database CADWorx also lets you work with a live database. A live database means that a database program is running at the same time CADWorx is running. Each time you place a component in CADWorx, it will instantly write a record for that component in the database program. This method let’s you work with the project while in the drawing, and also from within the database. You can switch back and forth if needed. For instance, you can also modify descriptive information in the database, and it will update the component information in the model when it synchronizes (you can do this with an intermittent database also).


191


To Run the System with a Live Database 1. 2. 3. 4.

•

You can do this for multiple drawings, and build a global material list

These steps actually just set the system up. The live database takes effect when CADWorx is restarted. It will stay in effect until it is switched off, using the same dialog box you just worked with.

Example of Exported Database This next section shows the kind of data that CADWorx puts in the database tables. In this example, you’ll export out drawing data to an external database. You can do this from multiple drawings into the same database, if needed. That way you could compile a database that contains all the material information for a number of drawings, and produce a global material list. 1.

Click Plant, Accessory, Database, Export.

•

Importing database information into the drawing – this generates new components or updates existing components

•

You can compare data in the P&ID to the data in a piping model

If you start a new drawing, using a template, and execute this command, the system will draw piping components from the information it gets from the database. Comparing P&ID Data to the Piping Model CADWorx can compare the valves in a P&ID to the valves in the piping model, by using database tools and cross checking them. In this lesson, you’ll be comparing the valves in the P&ID sample drawing against the model example. 1.

Open the drawing called Partial_Model_Example. It’s in the C:\CADWorx_Video_Training\Examples\Project_Database folder.

2.

•

The portion of the piping model that will be used to compare the valves in the model to the valves in the P&ID

•

The P&ID that will have its valve data compared to the piping model

As you watch the video, it will cover how the P&ID needs to be created, in order for the data tables to be linked and compared.


199


The P&ID has to be drawn in CADWorx P&ID using the same specs and line numbers. Also the P&ID will need to have the “Process Assign” command run across the process lines (see the video for how this is done). 3.

•

The P&ID has to be created in CADWorx P&ID using certain procedures

•

When you type PIDView in CADWorx, the system will bring up a box showing the P&ID valves and the valves in the model

•

You can link valves and check consistency

Type: PIDView . The system will add a dialog box next to the drawing showing the valve data in the P&ID and the model.

4.

Click on a valve in the P&ID area of the table, and it will appear in the window at the bottom of the table.

•

5.

You can click on a gate valve in the model section of the table, right click and click zoom.


201

You can zoom into valves in the model by clicking it in the data list (as shown in the video)


The system will zoom into the corresponding valve in the model.

6. 7.

•

You can click a valve in the P&ID section, right click and zoom into the corresponding valve in the model

•

When you’ve identified the valve in the model that corresponds to a valve in the P&ID, you can do a Link on them

•

Linking valves will allow you to check consistency between the P&ID and the model

Click on the other Gate Valve, right click and zoom to it. Once the proper valve is identified, you can link the P&ID valve to the model valve (see video for how this is done).


202


You can also insert a valve from the P&ID data right into the model. 8. 9.

Click the valve you want to insert in the P&ID list. Right click, and click Insert in Model (see video for how this is done).

•

You can then place the proper valve right into the model.


203

You can insert a valve from the P&ID data right into the piping model


Project Administration – Managing the Model

•

It is important to organize your model in a way that improves productivity

•

Each discipline will have its own sub folder

•

You will make extensive use of External Reference files (Xrefs)

When working on a model that is relatively complex, it is important to set up a good organizational structure. •

What you should do is set up a project folder, with each discipline having its own folder under the project folder. For instance, in this course, you will have a project folder called Area_35. Underneath it are the various discipline folders.

You could have other folders also, depending upon your project and your work process (Clearances, Buildings, Underground, etc.).


204


•

•

Then you place your discipline drawings within these sub folders and you can divide the work among a number of users. Each user then works on his or her assignment, and Xrefs in other drawings as needed.

•

There are a series of discipline “master” drawings

•

There is a “Project Master” drawing

•

It is important to have one person in charge of the model

•

CADWorx is completely scalable. There is no project size limit for a well organized design

There will be a series of “Master” drawings for each discipline. These master drawings will have all the individual drawings Xreffed into them (see video for recommendations on this).

•

There will be a Project Master drawing with the discipline master drawings xreffed into it. View the video for a discussion of these topics.

•

It is important to have a single model coordinator that controls these files. This way it can be managed effectively.

•

There is no limit to the scalability of CADWorx projects, if they are well organized.


205


Using Sheet Sets Sheet sets automate the creation of views (standard and clipped) in Paper Space viewports. Paper space views are preferred since they are “live” views. If you change the model, the view will update. This way you have no surprises. You can also annotate and dimension on the paper, with associated dimensions. Then if the model changes, the dimensions will also change.

•

Sheet Sets are a great time saver in producing drawings

•

CADWorx can easily create clipped views with its View Box command

•

Paper Space views are “live” views. Using them, if the model changes, all your details change

The first part of the video shows View Boxes, which easily set up clipped views (these are also covered in the earlier piping lesson four, and also in the structural skid one lesson).

Watch the videos for an easy introduction to how Sheet Sets work.


206


When you create these clipped views, they can be easily accessed from the View tool bar.

Using Sheet Sets, these views can be dropped into layouts (Borders) with scaling and labeling automated and made easier. The video makes use of a sample sheet set that is supplied by AutoCAD. This makes it really easy to do.


207

•

Named views are easy to call up from the View tool bar

•

A clipped view created with the CADWorx View Box command

•

Sheet sets really save time if you have a number of views (drawings) to produce


•

In this example, you’ll use a sample sheet set supplied by AutoCAD

•

You’ll set up some project information as you go through the wizard

•

You’ll specify which model files you want to use for your drawings

Follow the video to see how this works. You will quickly be producing scaled and labeled views for your drawing production. When you work with the Sheet Set Manager, you will set up some information about your project. This will help later because the system will build you a drawing list automatically. You’ll then tell the system the model files, which contain clipped or standard views you want to use.


208


Then you’ll choose a sample layout. .

•

You can choose a border

•

You fill out a drawing name and number

•

Then you drag and drop views into your layout

•

It’s very quick and easy after you do it a time or two

A few clicks later and you will be dropping in views with scaling and labeling. It’s a great time saver. Watch the video and it’s easy to follow all the steps.


209

CADWorx® Video Training Series Module Two – Editing CADWorx Specifications

Editing CADWorx Specifications Some topics covered in this lesson: You will . . . • Learn how to open a sample spec and examine it • Create your own spec • Review the contents of a spec • Add and delete items to your spec • Modify descriptive information and size ranges • Add Valve Tags • Add Part Numbers (Procurement Codes) • Add new Control Valves to your spec as optional components • Add new size ranges that are not standard • Create special end conditions components • Use Keywords to create look up values in the long description (wall thicknesses) • Print out your spec for review • Update your spec in the middle of a project 1.

•

In this section you’ll cover many aspects of the Specification Editor

•

Starting the CADWorx Spec Editor

Start CADWorx Plant and type SPED (or Click Plant, Accessory, Specifications, Editor). This will start the Spec Editor.

2.

You will see a list of all the specs that ship with CADWorx. Notice the extensive list of specs included when you purchase CADWorx. There are over 70 piping specs that are bundled into the software. Some of these are imperial specs, some are metric, and some are mixed metric (imperial bore sizes, with metric length measurements). There are also stainless steel specs, pvc, lined pipe, victaulic, FRP, Swagelok, etc. The system ships with these specs supplied, and it is very easy to add your own spec as needed. CADWorx supplies a library of components with over 60,000 components defined. Written by Anthony W. Horn © 2011 CAD Training Technologies, LLC Houston, TX USA

• 20. 21. 22.

Click Edit In the Tag field, Type: A2R .

Working with Part Number (Procurement Codes)

Adding Part Numbers (Procurement Codes) CADWorx has the capability of inserting a part number into every component. This can be set up by clicking the Edit Codes button (lower right area of the dialog box). The system will display the default part numbers for a Gate Valve.


214


•

The Part Numbering file in CADWorx: DBCodes.dat

•

Adding a Part Number to a Gate Valve

This is a very easy system to maintain. For instance, if you wanted to update the part number for a 6” Gate Valve. 23. 24. 25.

Click 6.00 (on the right). Put in your part number (in this example Type: A2R_6_150. Click the Update button (lower right). You can see that this part number system is easy to use. Near the very top of this dialog box is the path name of the part number file, C:\ CADWorx Plant 2007\Spec\Dbcodes.dat. This is actually a text file that can be modified using this easy dialog box interface, or with a text editor. Some CADWorx users also have written automated programs that update this text file as they add new parts to their procurement purchasing system.


215


These part numbers can be brought into Bill of Materials list in CADWorx drawings and Isogen. They can also be used for automating ordering items with your purchasing system. 26.

Click OK, to exit this dialog box (The Database Codes Editor).

Other Spec Information Carried in this Dialog Box •

The Short Description is used in Component Annotation

•

The Sort Sequence determines the position a component takes in the Bill of Materials

•

The Index Code is a category value used in Part Numbering

•

Looking at Data Files (the “measurement file”)

Looking further at the items in this dialog box: 27.

28.

29.

The Short Description’s value will appear on the drawing when placed there using the Annotate Component command (covered in the first piping lesson). The Sort Sequence tells the system how to sort the items down the Bill of Materials. A zero will make it first in the BOM list. A 999 will make it last in the list. If two items have the same value, then they will be sorted alphabetically in the BOM. The Index Code is a category code for the part numbering system. It tells the system where to look in the part numbering file (dbcodes.dat) to look up a component’s part number. It would probably not be necessary to change this value.

Looking at the Data Files Also, notice near the top of this dialog box, the information about the Data File (the library file) where the measurements for this component are stored.


216


30.

Click the Open button to open the data file. This is the file that contains all the measurements needed for CADWorx to draw the Gate Valves to scale. Also, notice there is a column for the weight. CADWorx carries weights for all components.

•

Data files – Contain all the data needed to draw a component

•

Expanding Data Files – Adding new size ranges

.

Adding New Size Ranges It’s very easy to add new size ranges to the data files. Since they are text file, all you have to do is modify right in Notepad. To add data for a 36” Gate Valve, copy the line for the 30” Gate Valve, and paste it into the line below. Then change the measurements as needed for the 36” data (use the data from a valve catalog). For instance, you could add 36” data as shown next:


217


31. 32. 33. 34.

35.

Close the file and save it. Click Save and then OK to close the spec Editor. Set your size to 36”, and click the Gate Valve tool button. Click two points to place the new 36” valve into your drawing (hit cancel if prompted for a Gasket, it could be added later). Set your size back to 6”, which you’ll be drawing later.

•

Testing a 36” Gate Valve

You can then have the system use the 36” data by changing the size range in the Edit Component dialog box for the Gate Valve.

•

Specs are “filters” that utilize portions of the library data files

•

Testing a 36” Gate Valve

•

Adding a new Control Valve to your spec

•

A new type a Valve is added

Note: This is also discussed in the video. From these discussions, you can see that CADWorx has a very simple scheme for its specs and data files. All the data files are stored in the library folders (Lib_I for the Imperial measurement files). CADWorx specs are set up to use portions of these data files. The specs have a size range set in them, to use either some, or all, of the lines in the data files. In the case of the Gate Valves, the range in the spec is 2” to 24”, while the actual data file (we looked at earlier in Notepad) goes from 2” to 30”. The Lesson Four video discusses a network setup to place your specs in a read only folder. Adding a New Control Valve It’s an easy process to add a Control valve to your spec. CADWorx ships with a number of control valves in its libraries. Sometimes you will have a project that calls for more than one choice for a control valve for a particular size. When this occurs, you will need to have multiple choices in your spec. The spec will contain one of the control valves as a default choice, and the others as “optional” choices.


218


First, you need to look at what’s currently in the spec.

36. 37. 38. 39.

To do this Set your size to 3”. Set the specification to A10. Following the video, click on the Control Valve button and place one in your drawing. Double click the control valve to view the data in it, then close the component edit dialog box.

•

Placing the default control valve

•

Looking at the data file for the default control valve

•

Telling the system this is an Optional Component

Add the valve as instructed in the video, noticing how it gets specified as an “optional” component.

.


220


44.

Save and exit the spec as directed in the video. The video discusses how to display Optional Components using both the Specview tool palette and also using tool bars. Follow the video to see how this is done. Showing optional components using Specview:

When this is set, the optional valves appear in the list in a different color.


•

Setting Specview to show optional components

•

The optional control valves appear in the Specview list

.

221


If you prefer to use tool bars, you can set the system to use optional components using the Settings tool bar. Showing optional components using tool bars:

Using this method, all the control valve choices appear listed in a dialog box.

Follow the video and bring in the control valves as directed and test them. You will find this a very powerful tool for adding great flexibility in getting you specs just the way you need them.


•

Having the system show optional components

•

Using optional components gives you the flexibility of adding multiple choices for your spec’s components

.

222


Adding a Gate Valve that is Threaded on one end, and Flanged on the other. Creating Components with any combination of end types. So far, you have added regular components to your spec, but suppose you wanted to add fittings with end type combinations that are not standard. CADWorx allows you to work with components with fifteen different types of end conditions. When working with components that CADWorx draws, this option allows you to create many types of optional components.

•

Opening the Sanitary toolbar

•

Next you’ll open the Help system to see the choices of End Types available

To create this type of component 45. 46. 47.

Click Plant (from the pull down menus) Click Toolbars Click Sanitary

This brings up the Sanitary toolbar. This is the tool bar used to place these special types of components.

48. 49. 50. 51.

Click Plant Click Help Under the Index tab Type: Sanitary This page will show the different end types that can be defined in CADWorx.


223


Notice that a Type 1 end type (shown in the previous dialog box) is a Weld end type. You can also see that a Type 2 end type is a Flanged end type, and so forth.

•

You can build components with different end types that are listed in the dialog box. For instance, a valve that is treaded on one end, and flanged on the other end, would have a Type 15 for the threaded end, and a Type 2 for the flanged end.


Above, you’ll see the many options CADWorx has available for building components with different end types

224


To illustrate this, you will a valve with “special end types”. To Add a GATE Valve that is Threaded on one end, and Flanged on the other End to your spec: 52. 53.

Restart the CADWorx Spec Editor (Type: SPED ). Click on the A10 spec.

229


Using Keywords in the Long Descriptions in the Bill of Materials Keywords allow you to put a variable value in the Bill of Materials, which can be a really nice feature. For instance, you can include the Wall Thickness of a component as part of the Long Description. When it is set up properly, the system will look up the proper wall thickness, and place it as part of the description text string in the BOM. The different keywords are: {BORE} {MAIN} {MAINACT} {RED} {REDACT} {SPEC} {MAINTHK} {REDTHK} {LENGTH} {PIPETHK} {PIPETHKRED}. Four additional keywords are also available if main and reduction sizes are needed in decimal format. These four additional keywords are: {MAINDEC} {REDDEC} {MAINACTDEC} {REDACTDEC


•

Keywords – “Wildcards” in the material list

•

A list of the many Keywords available in CADWorx

230


The keywords {BORE}, {PIPETHK} and {PIPETHKRED} are derived from the pipe's data file in the specification instead of the component's data file where {MAINTHK} and {REDTHK} are derived from. For example, a 4" valve with the {BORE} or {PIPETHK} would get the keyword values from the 4" pipe data file as listed in the specification. A 4" valve with {MAINTHK} or {REDTHK} would get the keyword values from the valve data file as listed in the specification.

•

How Keywords can be put to use

•

Using the {PIPETYK} keyword – having a wall thickness appear in the Bill of Materials

Since fittings have the same wall thickness as the pipe, it’s easiest to use {PIPETHK} when you’re working with these. Here’s an example. 95. Start the CADWorx Spec Editor (Type: SPED ). 96. Click on the A10 spec. 97. Click on Elbows, 90 (in the left section of the dialog box) 98. Click on the 2 to 24 Elbow. 99. In the Long Description area, modify it to include the text “THK” and the {PIPETHK} keyword as shown.

100. 101. 102. 103. 104. 105.

Click OK when done. Click Save (to save the spec). Click OK (to exit the spec editor). Set your size to 6”. Draw a piece of pipe, and elbow, and a piece of pipe. Double click on the elbow, to verify the Long description has a thickness value in it.


231

•

Using your own Border

•

Specifying your Border

•

The border drawing you use must be saved as a 2004 dwg

A couple of important things you must do: a. You must point to the border’s location using the Project Manager. It’s in the area labeled Drawing Frame.


254


b. The border you use must be saved as an AutoCAD 2004 drawing. Isogen will not work if you use a border that is an AutoCAD 2005, 2006, 2007, 2008, or 2009 drawing. Using your own Border, or a Client’s Border 89. 90. 91. 92.

•

Opening the border and saving it as an AutoCAD 2004 version

•

Specifying your Border

•

The border drawing you use must be saved as a 2004 dwg

•

Testing the border

Start regular AutoCAD. Open the drawing (in your “Examples” folder) named Client_A3_Border_0. Do a File, Save As. At the bottom of the Save As dialog box, set the Files of Type area to be an AutoCAD 2004.

93. Click Save and Click Yes when prompted to replace it. 94. Close AutoCAD.


255


Assigning the new border to the Isogen Project 95.

In the Project Manager, Click in the area called Drawing Frame.

•

96.

Click Browse.

97.

Browse to your Examples folder and select the Client_A3_Border_0 drawing.

98.

Click Apply.

Setting up the new border

This instructs the system to use your border now, instead of the default border. 99.

In CADWorx Plant Pro draw a simple drawing that consists of some pipe, flanges, valve, and elbow (see the following figure).


256


•

Creating a small test model

•

Generating an iso on the new border

100. Test the border by running a simple iso using it as the drawing frame.


257


Developing the Border – Filling out the Title Block Area Isogen does not use normal attributes to fill out the title block area like a regular AutoCAD drawing. Isogen uses “Positioned Text” for this function. In Project Manager – 101. Click in the Positioned Text area.

•

Positioned Text – used to place text in a drawing

•

Opening the Positioned Text file

102. Click the Edit button.


258


This opens up the Positioned Text file that you can adjust to map the locations of pieces of text onto your border.

•

Looking at the contents of the Iso_A3 sheet’s positioned text file

•

Opening the Positioned Text help file

•

You can Justify the text (Left, Center, Right) and you can Rotate the text as needed.

103. Close Notepad now, don’t save any changes. Note: Open the Positioned Text help file (a pdf file). It is found at C:\CADWorx Plant 2008\Isogen\Isogen_Utils\POS_Help.pdf You should print out this file, since it is only six pages and has some useful information in it. You can see from the file we opened in the previous figure that there is an item named -6. It has an X position, a Y position, a Character Width, and a Character Height. The numbers for position and height are in hundredths of a millimeter. Since Isogen was originally developed in Great Britain the values are in metric. The Positioned Text file can actually have more columns than shown above. This can be useful, because you can specify the text’s justification and rotation angle as well. Here’s an expanded version of one of the lines with the item labeled -6.


259


A Justification (column 11) of 0 is Left, 1 is Center, 2 is Right. The Rotation (column 12) can be set as needed (usually 0 or 90). If you look at the following figures, you can see that the item labeled -6 is what Isogen uses to place the drawing title (it uses the pipeline name).

•

Some of the fields that can be brought into your title block and drawing

•

This area allows you to create User Fields that can be mapped into your drawing. You can create as many as 100 fields

The Positioned Text help file has the following information in it.

You will use this information to map some values into your title block.


260


Note:

What they are calling a “User Defined Attribute Block” in the figure above is not something that comes from AutoCAD. This is Alias’ own naming, and it is used differently than attributes and blocks are used in AutoCAD.

104. In Project Manger – 105. Click the Project Name (above the Metric_Inch_A1 – this example is showing an Ansi_B sized border. All units work the same here.)

Click Project Defaults. This brings up the Project Defaults dialog box. 106. Click on the tab labeled Specification. The Specifications area of the Project Defaults


•

Opening the Project defaults dialog box

•

The project defaults is where you can put text that can be mapped into the title block area, or anywhere in the drawing

•

In the Specifications area are some fields you can fill out and have them get placed into your isometrics automatically

261


Any values in these fields (Piping-Spec, Insulation-Spec, etc.) can be mapped into the drawing or title block. For instance the Piping-Spec would be brought in using the code of -11. You would add a line to the ANSI_B.pos file (shown in a previous figure) starting with an -11 entry. Then you would add its X and Y position, and its height. You could do the same for the other specs, like InsulationSpec, Tracing-Spec, etc. Next you’ll map in some examples to see how this works. 107. Click the Miscellaneous tab.

In Project Manager, 122. Click on the Imperial_Inch_Ansi_B (or the border you’re working with). 123. Click in the area for Positioned Text.


265


124. Click Edit, to open the positioned text file in notepad.

Modify the file as shown.

One comment : In this example above you mapped in a fixed date from one of the fields you set up (it’s listed as the –602 line of information). You could have used a system date if you wanted to. It would be done by using a –14 (instead of a –602 like you used). Also on the drawing options, System tab, switch 6 lets you set a date format as needed (see videos). 125. Save the file under the name. 126. Client_Border_B_at_0.pos, or Client_A3_Border_0, depending upon the border you’re working with (make sure you don’t save it as a .txt file. You’ll have to set the file type All Files).

Testing and viewing the results

So you can see that Isogen allows you to fill out your title block as needed. If you wanted to use a border that had the title block running up the side of the drawing, you would use the same procedure. The only thing you’d need to do differently is have a 90 for the rotation angle in the positioned text file.


267


For example , the following line would map a text string into the title block area, but rotate it at 90 degrees instead of leaving it a 0 degrees. -601 31375

Video Seven illustrates how to have the system set up your layer colors to match the standard Isogen borders.

Lesson Seven Video One Video Two Video Three The Lesson Seven videos cover how to use and modify the different Bill of Materials Styles available with CADWorx and Isogen.

Lesson Eight Video One Video Two These videos discuss Line Numbering and how to run the Isogen Batch command. Also the graphic symbols for a floor or deck penetration, flow arrows, etc. are covered and you will see how they can be sent from the model to Isogen automatically.

Lesson Nine Video One Video Two Video Three

In this lesson you will how to place restraints (hangers, base supports, anchors, etc.) in the model and have them come into Isogen. You’ll also see how to get Detail Sketches of a Base Support to be drawn in the isometric. Finally, this section illustrates how to get a Reference Dimension and Note to appear in an Isometric.


269


Additional information (no videos associated with this section) Welding Information It is possible to have Isogen display Welding information on an isometric. It can list and number the welds in the drawing. The easiest way to see how this happens is to use one of the samples that are shipped in CADWorx (available in Imperial versions only at this time). 133. In Project Manger, Click on Project 1 •

Setting the system for welding information on isometrics

Click on the New Style button.

134. Fill out the New Style information as shown.

•

Use the Welding videos to see how to bring welding data into your own user border

135. Click OK 136. Click Apply (Apply makes this the default border). 137. Test your results. You should have an isometric generated with welding information on it.


271


Alternative Text Isogen has a text file similar to Positioned Text that is called Alternative Text. This file is used for labeling various notes that appear on the drawing. For instance, you can change the way Isogen labels the continuation notes when it breaks a drawing between multiple sheets. Currently it says CONT. ON DRG 2


•

You can change some of the labeling that Isogen puts on an isometric drawing

•

This is handled through a feature called Alternative Text

272


Let’s say you wanted to change the DRG over to DWG. In Project Manager, 138. Click in the area for Alternative Text.

139. Click Edit. 140. Click on the Group pull down menu (at the top of the screen). 141. Click on the Title Block group.

•

Opening the Alternative Text file

•

Looking at the Title Block Group in the Alternative Text file

This shows all the text in this particular group that Isogen uses for labeling.


273


Change DRG to DWG.

Look over the other Groups in the Alternative Text file. This file contains many labels that are open for you to change as needed. 142. Close the file (Click File, Save, and Exit) and click the Apply button. 143. You can test this by drawing a router line in CADWorx with multiple changes of direction, then running Plant, Accessory, Auto Route, Buttweld LR.

•

Changing the way Isogen labels “CONT ON DWG” instead of “CONT ON DRG”

•

It’s worth taking a look at the other groups in this file

144. When you run Isogen the system will break it into multiple isometrics. You will then see that it changed the continuation notes to CONT. ON DWG .

Setting up Square Elbows

The Data Definition File The Project Manager also has an are where you can modify the Data Definition File (similar to the Positioned Text file). This file contains settings that affect the appearance of how Isogen draws some of its components – for instance rounded elbows or square elbows. This file also contains information on what thickness of lines it will use, and how big it will scale some of the fittings. Also, there is a section in this file for defining layers,


275


Telling the System to Draw Square Elbows In Project Manager, 145. Click in the area for the Drawing Definition.

•

Opening the Drawing Definition File

•

Noting the area where Square Elbows are defined

146. Click Edit. 147. Change the word for ELBOW from ROUND to SQUARE.


276


148. Save the file (make sure it keeps a .ddf extension). 149. Test it on your previous drawing and verify the iso came out with square elbows. The help file that comes in the CADWorx\Isogen\Isogen_Utils folder contains further information on this file. The help file is titled DDF_Help.pdf.
