14. Holes • Holes • Drilled • Counterbore • Spotface • Countersink • Hole Type • Simple Hole • Tapped • Clearance Hole • NPT • Holes dialog box • Placement • Hole Type • Size • Drill Point • Termination

15. Holes • Holes • Placement • From Sketch • Hole Center • Sketched Entities • Linear • Select Face • 1st Reference Edge • 2nd Reference Edge • Concentric • Select Face • Circular Face or Edge • On Pont • Work Point • Positioned to an axis, edge or work plane

16. Hole • Tapped / NPT Hole • Thread Type • Size • Designation • Class • Diameter • Full Depth • Left Hand • Right Hand

17. Holes • Clearance Hole • Standard • Fastener Type • Size • Fit

18. Exercise 4-2 • Creating Holes

19. Threads • Threads • Internal and external • Graphical representation • Thread feature • Hole tool vs. Thread tool • Excel spreadsheet • C:\Program Files\Autodesk\Inventor 2008\Design Data\Thread.xls • Standards

20. Threads • Threads • Location Tab • Face • Display in Mode • Thread Length • Full Length • Flip • Length • Offset • Specification Tab • Thread Type • Nominal Size • Pitch • Class • Right hand or Left hand

21. Exercise 4-3 • Creating Threads

22. Shelling • Shelling • Thin walls (thickness) • Remove material (scooping out) • Hollow inside • Shell dialog box

23. Shelling • Shelling • Remove Faces • Thickness • Direction • Inside • Outside • Mid-plane • Unique Face Thickness • Different thickness • Specific face thickness • More button

24. Shelling • More Tab When no precise shell solution exists, allows a deviation from the specified thickness • Mean • Never too thin • Never too thick • Optimized • Specify Tolerance

25. Exercise 4-4 • Shelling a Part

26. Face Draft • Face Draft • Feature that applies an angle • Internal or external face • Face Draft dialog box • Fixed Edge • Fixed Plane • Pull Direction • Direction • Flip • Faces • Arrow displayed & direction • Draft Angle

27. Face Draft • Face Draft • Fixed Edge • Pull Direction • Select near edge to start draft • Fixed Plane • Select planar face or work plane • Flip plane if needed • Select planes to apply draft

28. Exercise 4-5 • Creating Face Drafts

29. Work Features • Work Features • Special construction features • Help position & define new features • Parametrically attached • Types • Work Planes • Work Axes • Work Points • Different situations

30. Work Features • Creating a Work Axis • Acts like a construction line • Infinite in length • Axis of rotation • Creating Work Points • Grounded Work Point • Positioned in 3D space • Not associated • Remains in the specified location • 3D Move/Rotate dialog box

31. Exercise 4-6 • Creating Work Axes

32. Work Features • Creating Work Planes • Understand when you need to create a work plane • Rectangular plane • Parametric • Larger than the part • Edited and deleted like any other feature • Methods – lots of solution • Visual Syllabus

33. Work Features • Creating Work Planes • Types of Work Planes • Angled work plane • Offset work plane • Tangent work plane • 3-point work plane • 2-edge or 2-axis work plane • Midway between two parallel planes • Feature Visibility • Off or On

34. Exercise 4-7 • Creating Work Planes

35. Patterns • Patterns • Duplicate the feature multiple times • Distance or angle • Types • Rectangular and circular • Suppressed • Child - parent relationship • Editing

36. Patterns • Rectangular Patterns • Rectangular pattern dialog box • Direction 1 • Direction 2 • Options - More button • Start • Termination • Orientation

37. Patterns • Circular Patterns • Circular Pattern dialog box • Placement • Creation Method • Positioning Method • Flip • Linear Pattern • Pattern Along a Path • Ellipse, spline, series of curves • 2D or 3D
