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

2. Click on the Metric.dwg and click OK.

data

74. Zoom in around one of the six inch flanges on the right,

and using the OSNAP Endpt, click on the Gasket, then drag to the right and Click.

75. Double click on the Long Weldneck you just placed, and

notice the information contained in this dialog box. a. The Long annotation area shows how the item will be

listed in the Bill of Materials List. b. The Tag is a field that can contain connection info (Nozzle 1 of Pump 123) or, in the case of a valve, a valve tag. All components carry weight. c. The Length field is fixed, it cannot be edited.



18

• Setting the nozzle to

be an Existing components

• Adding the 4”

Gaskets and Nozzles

76. Click on the “Existing” check box, and set the nozzle to

“existing”. This will make it an item that will be shown on an iso, but not called out in a material list. (It’s like the nozzle “exists” on a vessel in the area, and we just want to connect to it).

77. Click OK when done, and notice how the flange has

changed. 78. Repeat these steps and place a nozzle (Long Weldneck)

on the other 6” flange. 79. Near the top of the screen, in the CADWorx tool pallet: 80. Set the Main Size to 4” (don’t worry about the Reduction

size, it doesn’t matter for this step). 81. Click on the Gasket button. 82. Click on the left edge of one of the 4” flanges, drag the

mouse to the left, and click (place a gasket on the face of one of the 4” flanges).

83. Click on the Long Weld Neck flange button.



19

• Setting the Nozzle to

8” in length, and making it “existing”, which means it will come out in the Isometric drawing, but not in the Material List

• Viewing a proper

Gasket

84. Right click on the mouse and click Length. 85. Type: 200 <Enter> (to set the length to 200mm). 86. Press <Enter> again on the keyboard to connect

automatically to the gasket. 87. Drag the mouse to the left and Click. 88. The Long Weld Neck flange (the Nozzle) will be placed

correctly. 89. Double click on the nozzle and set it to Existing. 90. Notice there’s a space between the Nozzle and the flange

it connects to. The Gasket creates the space between them. This is how it should look.

91. Repeat for the other 4” flange, or copy the gasket and

nozzle up to it. Your drawing should look as shown at this point.



20

• Adding Bolts to the

drawing • Viewing the Bolt

Data

Adding Bolts 92. Type: Autobolt <Enter> 93. Window the drawing and press <Enter> 94. Bolts will be placed in the drawing (the system puts bolts

for each Gasket). 95. Double click on one of the “B”s laying on a Gasket (the

B’s are for “Bolts”). You can see what the system has put in for bolt information.



21

• Setting the system to

show Threaded Components

• Placing a Thredolet

Adding Olets (Drains) 96. Turn on the OSNAP, OTRACK, and POLAR buttons

at the bottom of the screen. 97. Click the Main Size area in the tool pallet. 98. Set the main size to 6”, and the reduction size to ¾”. 99. Zoom into the upper left area of the piping. 100. Click the Settings tab on the Specview tool pallet. 101. Click the Show Threaded checkbox. 102. Click Thredolet

103. Move the cursor right over the point where the pipe and the reducer meet, but don’t click – just hover the crosshairs right over that intersection point.

104. The OSNAP will “acquire” the point. A Drag slightly to the right (you’ll see the tool tip box

appear). Note: OSNAP Nearest can interfere with Tracking.



22

• Placing a Pipe

Nipple • Setting the End

Conditions of the Pipe Nipple

105. Type: 125 <Enter> 106. Drag the mouse toward the bottom of the drawing (in the – Y direction) and click. 107. The OLET (Thredolet) will appear, and be oriented toward the bottom of the screen. 108. Pick the Nipple button. 109. Right click and Type: 100 <Enter> 110. Press <Enter> (to connect to the OLet, the last component drawn). 111. Drag the mouse toward the lower part of the drawing and click. 112. Press <Enter> <Enter> (to set the ends of the nipple to threaded, threaded). 113. Double click on the Nipple. In the dialog box, you’ll see TBE (for threaded both

ends).



23

• Placing a threaded

Gate Valve

114. Click OK, to exit the component edit dialog box. 115. Click the threaded Gate Valve button. 116. Press <Enter> (to connect to the last component). 117. Drag the mouse down and click. 118. In a similar fashion place another olet, nipple, and gate

valve on the pipe segment at the lower right area of the drawing.



24

• Placing the other

branch

Put it 100 from the end of the flange.

See illustration which follows. Your drawing will now look as shown.



25

• 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). Your drawing should look as shown.



26

• 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 Valve not placed correctly against gasket



27

• 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. Your line number will be Size-Service-Count-Spec.



28

• Setting up the Line

Numbering sequence

Setting up the Line sequence. 126. Click the down arrow under Category. 127. Click on Service, and click Add.

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>.

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. Click OK to exit this dialog box.



32

• 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



33

• Placing
