3. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-3 Table of Contents SectionPage Step1. Import Nastran Deck. 3 Step2. Use Organize command. 4 Step3. Explore Pick Options in EPD. 7 Step4. Explore Some Additional Menus. 13 Step5. Get Familiar with D,V,U Buttons (Pick Block). 19 Step6. Alternate Method For EPD. 21 You will be importing an existing NASTRAN deck of a decklid model, and using it to explore the various Pick options and the Organize command As in the other tutorials, all menu items that need to be selected will be preceded by a maroon right arrow: >User action. Mouse buttons are indicated as follows: -- 1B = First (left) button -- used for selecting items -- 2B = Second (middle) button -- used for "OK" -- 3B = Third (right) button -- used for View Manipulation & pop-up menus Normally 1B is used, unless otherwise

4. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-4 a.Launch MSC.SOFY according to your local configuration. b.Select NASTRAN mode from the entry screen. c.Import a NASTRAN deck. 1.Click and hold the File Open icon with (1B). 2.By holding down the mouse button, you should see a sub-menu appear with various file types. 3.Select >NAS icon 4.From the file open dialog, navigate to the file: sofy_inst/SOFY3.0/SOFY_MASTER2/DEMOS/ Tutorials_Basic/Tutor06_pick_organize.nas (Alternatively,you can use Top Bar (select) > File Menu >Import > NASTRAN) d.The model should appear as shown Step1. Import Nastran Deck. c-3 d

5. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-5 Now suppose we wish to focus on a couple of parts and eliminate everything else from the display. In a large model it may be inconvenient to find the parts on the list in the Collection block. Let's use Organize command instead. e.Zoom into the front left corner of the decklid, using Window Zoom tool. f.From the Graphics Display toolbar> click >Organize icon. g.Notice the Pick block (CVP menu, lower right) changes to show the Organize command options and Pick Types. e f g Step2. Use Organize command.

6. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-6 h.Let's choose >Keep option i.Select >Parts from the entity type list. j.Now click and hold the >1B and move it around the canvas. k.You should see different parts highlighted as you move the cursor. l.This can be handy for locating and picking parts, when there are many parts on the screen. m.Move the cursor until the >decklid outer (red part) is highlighted, then release. m.Select also >decklid inner (yellow part) from the canvas. n.Confirm with >2B (or click >DONE in Pick menu). Notice that only the two selected parts remain on the canvas and all others are turned off. k Step2. Use Organize command. (Cont’d)

7. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-7 o.In a similar manner you can turn parts ON by holding the cursor and moving over the general location of the part. p.In Pick block, change from Keep to >On. q.Click and hold the >1B and move the mouse around until the hinge reinforcement part (green) is highlighted, then release. r.Confirm with >2B and note the green reinforcement is returned to the display. Now to see how this picking function changes when hidden line removal is on, let's repeat the last few steps. s.Activate the >Shaded Wireframe icon in the Graphics Display toolbar. t.Click the >All On button in the Collection Block. u.Organize command > Pick Block >Choose >Keep, as before. v.Click and hold >1B and move around the surface of the decklid outer. Note that now you cannot pick the parts which are hidden behind the surface, as was the case in Wireframe display. However this option can be activated using Extended Pick Dialog. p s Step2. Use Organize command. (Cont’d)

8. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-8 Since we will be using the Extended Pick Dialog frequently, it will be called EPD for short. a.Open Extended Pick Dialog (EPD) box by clicking on >D button at left side of Pick menu block. b.In the EPD box> toggle (un-check) the box labeled >Enable Depth Picking. c.Now try selecting a part behind the surface, and you should find the depth picking feature is now activated and functions the same as it did in wireframe mode. d.Practice selecting parts to >Keep, then turn back >On using Depth picking e.Now let's use Organize command to select Elements to Keep/ Mask/ UnMask. Step3. Explore Pick Options in EPD. d b

9. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-9 f.Restore all parts to the display 1.Click >All On in Collection block. 2.Set View to >Plan view 3.Click >Fill button in View block. g.Organize command still active> EPD box open> change Pick type from Part to >Element. Notice how the Pick menu and EPD are context sensitive, and change to show appropriate options for the chosen command. h.Suppose we wish to keep only one ring of blue solid elements and remove everything else from the display. Zoom in on the area of adhesive (Gumdrop, blue color) as shown. i. Select >Keep in Pick block. f g h Step3. Explore Pick Options in EPD. (Cont’d)

10. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-10 i.In the EPD box, left side (Pick Elements by Ref.), select >From Node. On the right side of the EPD (Element Type), select >Solid. Now select a few >nodes which are connected to the blue solid elements. Notice that any connected solid elements become highlighted, while other element types are ignored. Don't confirm yet. k. Let's switch Pick Style to >Sketch mode to speed up the element l.Now click and hold the >1B while drawing a line around the area of solid elements, then release. i j k l Step3. Explore Pick Options in EPD. (Cont’d)

11. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-11 m.Now confirm with >2B and you should be left with the solid elements shown. n.Let's return some of the nearby elements to the display. Select >UnMask in Pick Menu. o.In EPD, return Pick Ref. to >Default, and Element Type to >All. p.Again use Sketch pick mode to >draw a line around the displayed solid elements. q.Confirm with >2B, and all the elements within the sketch area are returned to the display. m n o q Step3. Explore Pick Options in EPD. (Cont’d)

12. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-12 Now let's try out the Contiguous pick reference. a.Turn >Off the Decklid Outer by unchecking the box in the Collection block. b.With Organize command still active Select >Elements >Unmask in Pick menu. c.In EPD, change pick reference (left side) to >Contiguous, and Element Type (right side) to >Shell. d.Now select a decklid inner >element along the edge of the displayed elements, clicking near the element center. e.Notice that some, but not all, contiguous elements are highlighted.

13. SOF101, Tutorial 6, January 2005 Copyright  2005 MSC.Software Corporation T6-13 e.The selection stops at feature lines, where the break angle is greater than a certain value, say 15 degrees. You can check (and modify) the feature angle by going to Top Bar, >Options, >Element Options. f.Continue selecting elements along the edge to get a feel for the Contiguous pick reference mode, and perhaps try out different feature angles. Hint: Use >Zoom, >Pan and >Dynamic Rotation (View Manipulation menu) frequently to control your view and ease element selection. e Step3. Explore Pick Options in EPD. (Cont’d)

14.
