1. 2012 IDEA Tutorial

6. Simplify your 2D right side view to this object to be cut & pasted into Inventor. FYI 2D right side with dimensions is on teacher website under “2012 IDEA” folder and is on previous slide.

7. 1.Open a new Inventor Part 2.Create a sketch and paste in your 2d CAD drawing 3.Extrude the lower base 4.5” – be sure to use the “symmetrical” option in the extrusion tool palette

8. 4. Click the “+” sign by Extrusion 1 in the browser bar to display the icon for “Sketch 1” 5. Right click on “Sketch 1” and select share sketch

9. 6. Extrude the web.5” thickness – use symmetrical again

10. 6. Extrude the next part of the support web 1 - 9/16” Once more, use symmetrical

11. 7. Right click on Sketch 1 and turn off the visibility 8.Create a 2D sketch on the top of the object 9.Use circle and sketch from the center point to the end point

12. 10. Finish sketch 11. Extrude the circle using asymmetrical option First value is.25 Second is.875

13. 12. Create a 2D sketch on top of the new cylinder and draw a “point” at the center 13. Finish sketch

14. 14. Select the “Hole” tool and change the following in the pop up menu: Change to Counterbore Select Through All Change values to: 1 9/32.25 15/16

15. 15. Create a sketch on the top of the base 16. Draw a 5/16” circle / ballpark where to place the center 17. Draw a 15/16” circle that is concentric to the first circle 18. Use dimension to constraint the circle centers.625” in from each edge

16. *Still in the same sketch- 19. Use “copy” (in the Modify tool bar palette) to “select” the two circles, and then choose the center of the circles as the “base point” and drag duplicates down Use dimension to constraint the new circle to be.625” from the front edge *Note: you can always just draw the additional circles / do not have to use copy

17. *Still in the same sketch- 20. Use copy to duplicate from one side of the base to the other Use dimension to constraint the centers to the left edge

18. 21. Extrude the outside circles 5/32” tall

19. 22. Share Extrusion 5 sketch 23. Extrude the inside circles as a “cut” and through all 24. Turn the visibility of the sketch off

20. 25. Fillet Party Use the Fillet tool and swap to.0625” radius and then select all the edges that get rounded (look at problem packet) Click Apply

21. 26. Sketch on front of object: Draw three lines and dimension them 15/16” in from each corner and.125” tall Use fillet in sketch mode (set to.0625”) to round the upper corners 27. Extrude that sketch as a cut through all

22. DONE!
