Transcription

1 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 CAD Training Technologies, LLC Houston, TX USA 60

2 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. 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 _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. Starting the drawing Inserting External Reference Files (XRefs) 5. Click External References CAD Training Technologies, LLC Houston, TX USA 61

3 6. Click Attach 7. Browse to your C:\CADWorx_Training\Examples folder and click on the 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. 10. Close the XRef dialog box (click the X at the top). List of attached XRefs CAD Training Technologies, LLC Houston, TX USA 62

4 11. You will see your two XRefs now appearing on the drawing. 12. Depending upon your AutoCAD version, you can use the D 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). Opening the View Tool bar 13. Dock the View tool bar at the top area on your screen. 14. Click on the South West Isometric View. Viewing from a 3D skewed view SW Isometric Viewpoint CAD Training Technologies, LLC Houston, TX USA 63

5 15. Zoom into the lower left area of the drawing. Zooming closer to the exchangers 16. In this lesson, you will be modeling the two lines that return from the top of the exchangers into the vertical tower. Getting an overview of what s to follow CAD Training Technologies, LLC Houston, TX USA 64

6 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. Isometrics the traditional way to work It s a short step from Isometrics to working in 3D when using CADWorx 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! CAD Training Technologies, LLC Houston, TX USA 65

7 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) Switching planes in 3D seems similar to flipping the crosshairs in isometric 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! 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) 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. CAD Training Technologies, LLC Houston, TX USA 66

8 Next you ll set up your system to draw some test lines to see how this works. 26. Click Plant 27. Click Setup 28. Set the Main Size to Set the Specification to 150_M. 30. Set the Drawing Mode to 3D. Practicing some 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. Make sure you have ORTHO 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 36. Type: 2500 <Enter> to draw a 2500mm length of pipe. Drawing a 3D pipe CAD Training Technologies, LLC Houston, TX USA 67

9 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). Placing a 3D elbow Modeling in the horizontal plane 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. CAD Training Technologies, LLC Houston, TX USA 68

10 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. Rotating the UCS easily into the vertical right hand plane 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. 48. Drag the mouse straight up and click. You ve just drawn an elbow going up. Modeling in 3D has a similar look and feel to creating Isometric drawings CAD Training Technologies, LLC Houston, TX USA 69

11 49. Click Pipe and press <Enter> on the keyboard. 50. Drag the mouse straight up and Type: 1800mm <Enter>. Showing how 3D is similar in approach to producing a 2D isometric 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. Click the UCS Next tool button on the UCS tool bar. 52. Set it as shown. 53. Click Elbow 54. Press <Enter> 55. Drag up for the corner and click. 56. Drag to the lower right and click. CAD Training Technologies, LLC Houston, TX USA 70

12 57. Click Pipe 58. Press <Enter> on the keyboard to connect automatically to the last elbow. 59. Drag to the lower right and 60. Type: 2500 <Enter>. Illustrating how to model in 3D Now let s say you wanted to draw a valve with flanges in the second horizontal line, where it touches the elbow that s turned up. You ll draw a gate valve and flanges here. First you need to get your crosshairs (UCS) reset. 61. Click the UCS Next tool button. CAD Training Technologies, LLC Houston, TX USA 71

13 62. Click the Weld Neck Flange on the tool palette. 63. Click on the end of the elbow that s turning up. 64. Drag toward the lower left area of the drawing and click. Inserting components into a line and having the system break out the line as they are inserted 65. Click the Gate Valve on the tool palette. 66. Press <Enter> on the keyboard to connect it to the flange automatically. 67. Drag the mouse toward the lower left area of the screen and click. 68. Click on the Weld Neck Flange in the tool palette. 69. Press <Enter> on the keyboard, to connect it automatically to the valve. 70. Drag to the lower left area of the screen (using Polar or Ortho) and click. CAD Training Technologies, LLC Houston, TX USA 72

14 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. Getting set for modeling CAD Training Technologies, LLC Houston, TX USA 73

15 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. Setting up the line number 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. CAD Training Technologies, LLC Houston, TX USA 74

16 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. Rotating the UCS (User Coordinate System) 77. Click Gasket from the CADWorx tool palette. 78. Place a gasket on the top of a nozzle (use OSNAP CENTER), and drag the mouse toward the top of the screen and click. 79.

18 88. Draw a piece of pipe connecting the two elbows. 89. Then click on the Tee, in the CADWorx tool palette. 90. Right click on the mouse and click Center. 91. Pause on the end of the elbow, on the right side (don t click). 92. Track down the pipe (drag the mouse down the pipe and you will see the system tracking), and type: 1738 <Enter>. 93. Click down the pipe for the Main Run direction. 94. Click Straight Up for the Branch direction. 95. Press <Enter> to accept the 1738mm distance from the end of the pipe. 96. Your drawing should appear similar to what s shown. Modeling 3D components Inserting a Tee into the middle of a 3D pipe 97. Save the drawing at this point. 98. Now you ll need to rotate your UCS (your crosshairs) to model in vertical, and also in the right hand plane. Click the UCS Next button to rotate them as shown. CAD Training Technologies, LLC Houston, TX USA 77

19 99. Zoom into the area around the two nozzles on the side of the vessel Place a Gasket, Flange, and Elbow as shown. Modeling in vertical The following figure shows what you will be constructing. You ll soon be modeling a line that comes up out of the Tee, and connects into the bottom of the Elbow.. CAD Training Technologies, LLC Houston, TX USA 78

20 The bottom of this new line will be at an elevation of Evaluating the setup You ll need to determine how far it is from the center of the Tee to the end of the Elbow on the vessel (you can just follow the steps in the video). First, you ll determine the distance from the Tee to the Elbow. Again, watch the video and this will be easy to follow. The video shows the following steps Click Tools 102. Click Inquiry 103. Click Distance 104. Click the Endpoint or Center of the Tee Click the Endpoint or Center of the bottom of the Elbow Note the distance between them (see video) it s 4845mm.

49 Setting up some Views in Paper Space When using AutoCAD 2009, you can set up View Ports easily using the View tab of the 3D Work Space. The other option, that works for all versions of AutoCAD is as follows Set your layer to Viewl (no matter which version of AutoCAD you are using) Open the Viewports tool bar (see instructions which follow) Move the pointer over any AutoCAD tool button and Right Click on the mouse. Setting the layer for a viewport Creating a viewport (options vary depending upon the AutoCAD version used) 328. Click on Viewports. CAD Training Technologies, LLC Houston, TX USA 108

50 329. Dock the Viewports tool bar at the top of the screen (do not dock it on the side of the screen) Click the Single Viewport tool button (the second button on the Viewports toolbar) Click two points to make a viewport on the screen, similar to what s shown. Setting the layer for a viewport Creating a viewport CAD Training Technologies, LLC Houston, TX USA 109

51 332. Double click the mouse inside the viewport area This takes you into Model Space. You ll see your crosshairs are active within the viewport Pan the drawing to the middle of the viewport Click the arrow on the side of the Viewports toolbar, and 336. Set the Scale to 1:50. Scaling the view in the viewport If you are using AutoCAD 2009 you can easily set the viewport scaling directly off the bottom area of the screen. CAD Training Technologies, LLC Houston, TX USA 110

52 337. Double click the mouse outside the viewport area. This returns you to Paper Space Cross through the edge of the viewport with the mouse, which will light up the Grips on the viewport Right click, and click Display Locked, Yes. Locking the viewport, to keeps its scale always set This locks the viewport and the zoom (scaling) stays locked. You can unlock it later if you want to, but this keeps the scaling fixed.

53 Creating a Second Viewport 340. Click on the Single Viewport button again, and create a second viewport as shown. Creating a second viewport 341. Double click the mouse inside the border of the second viewport (this makes it current and enters Model Space) Click on the arrow on the View tool bar, and 343. Click on the View named Skid_2-Front. Bringing the clipped view into the viewport CAD Training Technologies, LLC Houston, TX USA 112

54 344. Pan the drawing to the middle of the viewport, and 345. Click the down arrow on the Viewports toolbar and 346. Set the Scale (zooming) to 1:50. Scaling the clipped view 347. Pan the drawing as shown and 348. Double click outside the viewport to return to Paper Space Cross through the viewport to light up the Grips, 350. Right click and lock the viewport as you did previously (Display Locked, Yes) Set your current layer to Text (or any other layer except layer Viewl) Turn off layer Viewl and the layer Dim Save the drawing at this point. Locking the viewport CAD Training Technologies, LLC Houston, TX USA 113

55 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. Viewing the results to this point CAD Training Technologies, LLC Houston, TX USA 114

56 The other option is to flatten the views. This is the option you would choose if the client only wants flat 2D drawings as their deliverable. You will see how this option works in a later section of this chapter Zoom into the area around the top view Make layer CL the current layer Type: LTScale <Enter> Type: 10 <Enter> Draw some centerlines as shown. Use OSNAP Center, Quadrant, Midpoint, etc. as needed. Drawing some centerlines that will be used in annotation CAD Training Technologies, LLC Houston, TX USA 115

57 Zoom into the area around the vertical tower, in the plan view Click Plant 360. Click Text 361. Click Iso Text 362. Click 0 Deg Text Annotating the drawing 363. Click a point to start the text Type: 3 <Enter> (for the text height) Press <Enter> (for 0 degrees rotation) Type: C EQUIPMENT <Enter> Press the spacebar three times and 368. Type: N <Enter> <Enter>.

60 373. Using the videos as a guide, label the elevations as shown in the following figure. Labeling the elevations Setting the dimensioning variable for associated dimensions in paper space 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 Type: Dimassoc <Enter> Type: 2 <Enter>. 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. CAD Training Technologies, LLC Houston, TX USA 119

61 376. Using the video as a guide, add the dimensions and labels as shown. CAD Training Technologies, LLC Houston, TX USA 120

62 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. Congratulations! This completes this section.
