Lesson One Structural Steel

“Modeling a Pipe Rack” In this lesson you will model a piperack and produce associated drawings from the model in Paper Space using clipped View Ports.

In the Structural module you’ll cover a number of topics:

• Modeling 3D steel members and plate • Coping members for correct lengths and fitting • Setting up and running a steel Bill of Materials • Modeling Stairs, Handrails, and Ladders • Using Frames • Adding Grating to the data files • Producing drawings in Paper Space using clipped views • Generating a 2D representation of the 3D model • Annotating and Dimensioning using associated dimensions in Paper Space

For this lesson click on

the button as shown

• Opening the

35_Piperack drawing

• Bringing up the

Steel tool bar

To start this lesson, 1. Start CADWorx Plant Professional. 2. Click on the Open a drawing button. 3. Open the

C:\CADWorx_Video_Training\Examples\35_Piperack.dwg .

4. Zoom in and bring up the Steel tool bar.



280

• Clicking a Beam

tool button to model this type of member

• Setting the insertion

points for the steel. This assures it will come into the model as needed

Modeling 3D Steel Members 5. Dock the Steel tool bar near the top of the screen. 6. Click on the Wshape icon. 7. Set the dialog box as shown.



281

• Modeling the

columns • Setting the

justification for modeling beams

8. Model the four columns as shown. 9. Next you’ll model the beams. 10. Click the beam button again in the Steel tool bar. 11. Set up the dialog box as shown.



282

• Modeling the

HE 200A beams • Coping the beams

12. Model the cross beams (bents) as shown. Coping the Steel Members 13. Click on the Cope button, and cope the beams as shown in

the videos (the system prompts will give you the steps).



283

• Modeling the

HE 200AA beams

• Setting the sizes and

insertion point locations

• Coping the beams

14. Save your drawing at this point. 15. Next model the HE 200AA beams. 16. Click on the W Shape tool button. 17. Set the dialog box as shown. 18. Select the beams as shown in the video. 19. Click the Cope button and 20. Cope the beams as shown.



284

• Setting up the sizes

for the base plate

• Modeling the base

plate

21. Save the drawing at this point. Modeling a Base Plate 22. Following the video, set up the Base Plate dialog box as

shown. 23. Construct the base plate as shown in the video.



285

• Adjusting the hole

size in the base plate dialog box

• Erasing some

members to set up the model for arraying

24. Copy the base plate to the other column as shown in the

video. 25. Erase some of the extra members to set up the model for

arraying. 26. Now you’ll array the members and have them build a

complete pipe rack. 27. Pick Modify and Array. Have it set for Rectangular Array. 28. Fill out the dialog box as shown. 29. Select the end section (called a bent) and array it.



286

• Setting up the array

command to model the full pipe rack

• Arraying the pipe

rack bents • Setting up the array

for the connecting beams

30. Fill out the array dialog box for the connecting beams.

31. Select the side beams and array them as shown in the video.



287

• Setting up clipping

planes and views in the model

• Setting up the

clipped views for the drawing in Paper Space

• Setting up the page

on the layout

32. Save the drawing again at this point. 33. Set the view to a top view (plan view) Creating Clipped Orthogonal Views 34. Setting up clipped views for drawings in paper space. 35. Click the View Box command, following the steps in the

video. This will set up clipping planes and named views that you

can use in your paper space view ports. 36. Following the explanation in the video, fill out the View

Box dialog box as shown.



288

• Discussing Paper

Space and View Ports

• Setting up a page in

Paper Space for the drawing

37. Click on the Layout tab (at the bottom of the screen). Setting up a Layout (Paper Space) This will take you to the layout (paper space). 38. Right Click on the layout tab to bring up the Page Setup

Manager. 39. Following the steps in the video, set up the page as

shown in the following figure. 40. Following the video, set the layer to Viewl and open the

View Ports tool bar. 41. Next you’ll make a view port and bring in the clipped

view. This view was made automatically by the View Box command you ran earlier (see the video for step-by-step instructions).



289

• Creating a view port

and setting the clipped view to be active

• Scaling the view

port • Setting up

dimensioning for Paper Space

42. Once the view is specified, you can scale it and lock the

viewport. 43. Save the drawing at this point. 44. Verify the view port is locked. Dimensioning in Paper Space 45. Type: Dimassoc <Enter>. 46. Type: 2 <Enter>. 47. Check the Scaling in the Model (as shown in the video). 48. Turn off Layer Steel, to make it easier to click on the

centerlines for dimensioning.



290

• Placing a horizontal

dimension across the top of the pipe rack

• Turning off the steel

layer and dimensioning across centerlines makes it easier to select the points

49. Use the CADWorx dimensioning tools to place dimensions

on the layout (see Video Five). 50. Following the video, pick points and place dimensions as

shown.



291

• Annotating

Elevations • Generating the

elevation call-out

51. Next you’ll annotate some elevations (see video). 52. Following the steps, you’ll be able to generate the elevation

label as shown.



292

• Annotating

Components

Annotating Steel Members 53. As shown in the figure below (and also in Video Six), click

the annotate component button. 54. The system will read the steel member size and generate a

label for you.



293

• Annotating

Components

Modeling in Vertical, using the CADWorx UCS Tool Bar This video discusses constructing lines in 3D to use for

structural members. To model easily in 3D, use the CADWorx UCS tool bar. 55. Follow the video to see how to construct lines in vertical (in

3D) or horizontal. Using the UCS tool bar makes it easier than it normally would be, with the same look and feel as drawing a 2D isometric.



294

This concludes the lesson on modeling a pipe rack. In this lesson you’ve covered a variety of topics, including modeling components, generating clipped views in paper space, and dimensioning and annotating drawing in paper space. These topics get explored and carried further in the next lesson, which is modeling a structure.
