Getting Started
Some topics covered in this lesson: You will . . .
• Set up the screen for first time use • Save your “Workspace”
• Learn to place components • Learn dimensioning procedures • Set up and use the Bill of Materials • Learn how to annotate components • Learn how to set up Line Numbering
• Learn how to use the graphic labels in the system
• See that techniques you learn here will be useful when simple quick drawings
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!
• Starting up a drawing in CADWorx
• In this system you always use a template
• You can bring your border in at any time
• Using a template sets Units and other AutoCAD variables
Click the video buttons shown (Piping, Lesson One, Video One). The Video One gets you started and introduces the screen setup.
When you’ve finished viewing Video One, click the Video Two button. It will get you started setting up your drawing. Start CADWorx Plant Pro by double clicking on the
CADWorx icon.
1. Click on the “Use a Template” button

• Placing the other branch
Put it 100 from the end of the flange. See illustration which follows.
• 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
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.
To run this check: 119. Click Plant 120. Click Utility 121. Click Continuity
122. Window the drawings and press <Enter>
123. Type: 300 <Enter> (to have the system show the ends of the pipe runs and branches with a 300 diameter circle). 124. Press <Enter> (for the 0.0010 precision).
• 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 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 <Enter>, as you connect one component to the next, or not having a good OSNAP connection between components.
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
• Starting the Line Number Setup command
Line Numbering
125. Click the Line Number Setup Tool Button.
This brings up the Line Numbering System Dialog Box.
By default, the system uses Size-Spec as its line number.
You’ll change that now, to a different line number format.

129. The Count is now added as part of 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.
• Adjusting the line number categories
• Setting the values for the fields in the line number
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 <Enter>.

• Verifying the line number has been updated
Updating the Line Number in the Components
142. Type: Nba <Enter> (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.
143. Select everything in the drawing, and press <Enter>. 144. Type: A <Enter> (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.
• Moving the drawing over in the border area
• Selecting the Automatic
Dimensioning option
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.
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
• Placing dimensioning automatically 150. Right click on the mouse and type: 675 <Enter>

• 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
Component Annotation
Next you’ll label a couple of the fittings. 187. Click Plant
188. Click Text 189. Click Annotate 190. Click Component

198. Repeat for the 6”x3/4” Thredolet at the bottom left of the drawing.
Congratulations! This concludes the first lesson. You are well on your way to mastering CADWorx® Plant Pro software!
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
• 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 1. Start CADWorx, and open the Lesson_One drawing.
2. Click File, then Save As
3. Type: Lesson_Two (do a Save As, Lesson_Two). 4. Erase the Border, Bill of Materials, and Dimensions 5. 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. Drag and dock the toolbar in the top area of your drawing. 13. 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.
• Seeing the drawing in different display modes (2D, Single Line, 3D)
14. Next you’ll place the Settings toolbar at the top of your screen, next to the AutoCAD View toolbar you placed there earlier.
15. Click Plant 16. Click Toolbars 17. Click Settings
18. Drag it up next to the view toolbar in the top area of your screen.
19. 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.” 20. Move the pointer down to the “2D, “Single Line”, or
“Solids” button and release.
21. Click two points to Window all the objects, and press <Enter>.
22. 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.
• 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
23. Click View
24. Click Visual Styles 25. Click Conceptual
• Discussing 3D versus Isometrics
• Rotating the UCS, which rotates the crosshairs
26. Click View
27. Click Visual Styles 28. 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. Watch Video Two and Video Three, which discuss the Top Works feature in CADWorx.
30. Bring in the CADWorx UCS Toolbar – 31. Click Plant, Toolbars, UCS.
32. Doc it at the top area of your screen.
33. 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.
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.
• 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 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.
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.
• Tracking the thredolet down the pipe 125mm
• Placing a pipe nipple 39. Set the Main Size to 6”.
40. Set the Reduction Size to ¾”.
41. Click on the Thredolet button.
42. Have the OSNAP, Tracking, and Polar buttons turned on. 43. 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.
44. The system will “acquire” that point and you can “track” from it.
(If you see a box similar to what is shown, you are tracking.)
45. While tracking, Type: 125 <Enter>.
46. Drag the crosshairs toward the bottom of the screen and click.
• Viewing the spec data in the nipple The Thredolet will be placed 125mm from the end of the
pipe, and oriented downward.
Click the Nipple button.
Note: If you don’t see it in the list to select, make sure your Main size is set to ¾”. The system will display components based on size.
.
47. Right click on the mouse, click Length, and Type: 100 <Enter>, for a 100mm long nipple.
48. Press <Enter> on the keyboard, to automatically connect the pipe nipple to the thredolet.
49. Press <Enter> <Enter> to set the nipple end conditions to threaded for each end.
• Placing a threaded gate valve and plug
• Copying the other drain branches
Note: As long as the nozzle data shows “Existing”, the color and line type display are fine.
Double click on the nipple that you just placed on the drawing.
You’ll see in the dialog box that it is shown as TBE (threaded both ends) in the long description part of the dialog box.
50. Click OK to close the dialog box.
51. Click on the Gate Valve, 800 LB, THRD button.
52. Press <Enter> on the keyboard, and the valve will connect automatically to the pipe nipple.
53. Drag the crosshairs down, to indicate the direction, and click.
54. Click on the Plug button.
55. Press <Enter> to connect automatically to the previous component.
56. Drag the mouse down and click (for the direction). 57. Place the other drains needed on the drawing. You can
place them using these same steps, if you want the practice, or you could also copy them using the regular AutoCAD
• Adding valve operators • Inserting the dimensions of the valve operators Copy command.
58. Get them as shown in the next figure, all located 125mm in from the end of each pipe.
59. Save the drawing.

60. Bring up the Operator’s tool bar . 61. Click Plant
62. Click Toolbars 63. Click Operators
64. Dock it at the top of your screen.
65. Click the OS&Y tool button on the Operator tool bar.
66. Click a point in the middle of one of the 6” gate valves (use an OSNAP MIDPOINT if necessary).
67. Drag the cursor up (to indicate the direction of the hand wheel). 68. Type: 168 <Enter> (for the diameter of the hand wheel).
• Adding Valve Tags 69. Type: 857 <Enter> (for the length of the hand wheel).
70. Repeat for the other 6” Gate Valves.
Setting a Valve Tag and Valve Hand Wheel Orientation
71. Double click on one of the 6” gate valves, to bring up the Component Edit dialog box.
72. Later, when the specs have been set up, you will probably have a valve tag automatically come into the valve’s data. For instance, when the specs have been done, a value of G33P might be put in the TAG field automatically.
73. In this case, you haven’t modified the specs yet (probably), so the TAG field will be blank.
74. Fill out the information in the TAG area as shown. This will give the valve a TAG value (G33P in this case).
• Adding data to tell Isogen how to draw the valve operators
• Placing hand wheel information on the small drain valves Next you’ll tell Isogen how to draw the hand wheels for the
valves, if you are running CADWorx 2008 and earlier version. In CADWorx 2009, this is done automatically as the valves are modeled.
75. Click the Isogen button at the bottom of the dialog box.
76. Set the Spindle Direction to Up if it is not already set. 77. Copy and paste the TAG info into the other 6” Gate Valves,

81. Drag the mouse out away from the valve to indicate the hand wheel orientation.
82. Type: 60 <Enter> (for the hand wheel diameter). 83. Type: 125 <Enter> (for the length).
84. Repeat for the other ¾” Gate Valves.
85. Double click on the valve, and fill out the dialog box as needed for the TAG information and the orientation of the hand wheel. The Tag will be G33P.
86. In this example, the hand wheel will be oriented SOUTH (since it is pointing toward the bottom of the drawing). Two will be SOUTH, and two will be NORTH.
• Reviewing the finished model
87. Fill out the other ¾” Gate Valve TAG data as needed. 88. Save the drawing.
This completes Lesson Two. Next up – Isometrics!
.
• Opening the drawing
• Telling the system to generate an Isogen Isometric drawing of the line modeled
• Note: If Isogen is grayed out when you try to select it, see your system
administrator or the videos on setting up Isogen
Lesson Three
Running an Isometric using Isogen
Some topics covered in this lesson: You will…
• See how to run an isometric using Isogen
• Run the iso on various borders
• Look at some of the Isogen options
Note: There is a separate lesson on how to set up and customize Isogen (see page 238).
1. Open the Lesson Two drawing in CADWorx Plant Pro.
2. Click Plant 3. Click Accessory 4. Click ISOGEN 5. Click Isogen Out
• Use an A2 Border for this first example
• The system will generate two drawings You should see the following Isogen Configuration dialog
box. If not, see your System Administrator, or go through the Isogen Setup Video. This video is a later video in this training sequence.
6. 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.
7. Click OK.
8. Press <Enter> (to select components).
9. Window all the items in the drawing and press <Enter>. 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.
.
• You can generate the isometrics using different size borders
• There’s even a border that shows welding information on the isometric
the video for possible causes.
10. Click the Open Plot Files button, and take a look at the isos.
11. Now run the isos on the A3 border, and also the A1 border. 12. 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.
Welding Information
Isogen also has the ability to generate welding information on an iso.
To see how this works: 13. Click Plant
14. Click Accessory 15. Click Isogen 16. Click Isogen Out
Welded Iso – partially shown for clarity
• Reviewing the welding information results shown on the isometric
18. Click Sample-Final-Weld-Box 19. Click OK
20. Press <Enter>
21. Window everything and press <Enter>.
22. Click Open Plot Files to review the isometrics generated.
Note: The sample welding border is only available in Imperial Units at this time.
At this point you have been able to produce some Isogen Isometrics, providing everything has been set up for you. 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
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
• Starting the drawing
• Inserting External Reference Files (XRefs)
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. Start a new drawing, using a template: Metric. 2. Click File, Click Save As
Browse to the C:\CADWorx_Video_Training\Lessons folder.
3. Save the drawing as 12-CPRA_B-1004-150_M.
4. Click Insert, from the pull down menus in both 2009 and earlier versions. In AutoCAD 2009 there is also a button along the bottom of the screen, if you prefer.
• List of attached XRefs
6. Click Attach
7. Browse to your C:\CADWorx_Training\Examples folder and click on the 35-450 drawing and the Exchangers_Pair drawing (hold down the Control Key as you select them. 8. Insert them in as Overlays and inserted at the 0,0,0 point,
Scaled 1:1, and Rotated 0 as shown.
9. You should have them in your attached drawings list as shown.
• Opening the View Tool bar
• Viewing from a 3D skewed view – SW Isometric Viewpoint 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.
• Zooming closer to the exchangers
• Getting an overview of what’s to follow 16. In this lesson, you will be modeling the two lines that return
• Isometrics – the traditional way to work
• It’s a short step from Isometrics to
working in 3D when using CADWorx 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?
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!
• 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) Instead of the F5 key to rotate your crosshairs, CADWorx
uses their own UCS Toolbar, which does a similar function.
18. Now you’ll bring up the CADWorx (not AutoCAD’s) UCS tool bar (2008 version illustrated)
19. Click Plant (at the top of the screen) 20. Click Tool Bars
21. Click UCS
22. The UCS tool bar will appear. Dock it in the top area of your screen.
23. Notice how your crosshairs are oriented.
24. 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

32. Make sure you have ORTHO turned on.
33. Click Pipe
34. Click a point for the start point of your pipe. 35. Drag the mouse to the lower right direction and
• Placing a 3D elbow
• Modeling in the horizontal plane 37. Click Elbow
38. Press <Enter> on the keyboard to have the elbow connect automatically to the pipe you just drew.
39. Drag down and click (for the corner).
40. Drag to the right and click (for the elbow direction).
41. Draw a 1800mm piece of pipe from the elbow toward the upper right direction.
42. Now you’ll turn draw another elbow turning up in the vertical plane.
• Rotating the UCS easily into the “vertical right hand” plane
• Modeling in 3D has a similar look and feel to creating Isometric drawings 43. Click on the UCS Next button on the UCS tool bar.
44. 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.
Now you’ll draw some components in vertical. 45. Click Elbow
46. Press <Enter> on the keyboard, to have the elbow connect automatically to the last piece of pipe. 47. Drag the mouse toward the upper right direction and
click.

automatically to the valve.
70. Drag to the lower left area of the screen (using Polar or Ortho) and click.
• Getting set for modeling 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.
• Setting up the line number
72. Set the Main Size to 12”. The spec should be set to 150_M.
73. 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.
• Rotating the UCS (User Coordinate System)
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.
