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. •

•

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.

•

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

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
