1. Chapter 4 Creating Placed Features

2. After completing this chapter, you will be able to –Create fillets –Create chamfers –Create holes –Create internal and external threads –Shell a part –Add face draft to a part –Create work axes –Create work points –Create work planes –Pattern features Chapter 4 - Objectives

3. Fillets Fillets add material Rounds remove material –Fillet dialog box Constant Variable Setbacks Face Full Round –Edit fillet’s type & radius

4. Fillets Constant Tab –Same radius from beginning to end –Single set or multiple set Select Edge and Radius –Preview image Select Mode –Edge –Loop –Feature –All Fillets –All Rounds

5. Fillets Constant Tab –More options –Roll along sharp edges –Rolling ball where possible –Automatic edge chain –Preserve all features Preserve All Features

6. Fillets Variable Tab –Different start and end radius –Edges –Point –Radius –Position –Smooth Radius Transition

7. Fillets Setbacks Tab –Transition from a vertex –Three or more filleted edges meet at a vertex –Fillets can have different radius

8. Fillets Face Fillet –Select two or more faces –Faces do not need to be adjacent –Consume features

9. Fillets Full Round –Fillet tangent to selected faces –Select three faces –Faces do not need to be adjacent

10. Chamfers –Beveled edges –Interior & exterior edges –Single or multiple selection –Edit type or distance –Method Distance Distance and Angle Two Distances

11. Chamfers –Method Distance Distance and Angle Two Distances

12. Chamfers –Edge and Face Edge Face Flip –Distance and Angle Distance Angle –Edge Chain and Setback Edge Chain Setback Preserve All Features

13. Exercise 4-1 Creating Fillets and Chamfers

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

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

16. Holes Tapped 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 –Internal and external –Graphical representation –Thread feature –Hole tool vs. Thread tool –Thread Feature dialog –Excel spreadsheet C:\Program Files\Autodesk\Inventor 10\Design Data\Thread.xls Standards

20. 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 –Thin walls (thickness) –Remove material (scooping out) –Hollow inside –Shell dialog box

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

24. 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 Shelling

25. Exercise 4-4 Shelling a Part

26. 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 –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 –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 –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

38. Exercise 4-8 Creating Rectangular Patterns

39. Exercise 4-9 Creating Circular Patterns

40. Exercise 4-10 Creating Path Patterns
