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

18. Exercise 4-2 • Creating Holes

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

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

21. Exercise 4-3 • Shelling a Part

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

23. Work Axis • Creating a Work Axis • Acts like a construction line • Infinite in length • Axis of rotation • Create a Work Axis • Filtered Options – Only select data that fits the selected option

24. Exercise 4-4 • Creating Work Axes

25. Work Points • Creating Work Points • Point • Filtered Options – Only select data that fits the selected option • Grounded Work Point • Positioned in 3D space • Not associated • Remains in the specified location • 3D Move/Rotate dialog box

26. Work Planes • 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 • Filtered Options - Only select data that fits the selected option

27. Work Planes • Parallel to Plane through Point • Midplane between Two Parallel Planes • Midplane of Torus • Angle to Plane around Edge • Three Points • Offset from Plane • Two Coplanar Edges • Tangent to Surface through Edge • Tangent to Surface through Point • Tangent to Surface and Parallel to Plane • Normal to Axis through Point • Normal to Curve at Point • Types of Work Planes

28. UCS User Coordinate System • Use like a work plane • Place on existing geometry • Position with absolute coordinates • No limit to the number of UCSs • Constrain UCS to UCS • Contains • 3 planes • 3 Axes • Center point

29. Feature Visibility • Control visibility of • Planes • Axes • Points • Construction surfaces • Sketches • UCS • Turn off visibility of individual objects

30. Exercise 4-5 • Creating Work Planes and a UCS

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

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

33. Patterns • Linear Pattern • Pattern Along a Path • Helix, ellipse, spline, series of curves • 2D or 3D

34. Patterns • Circular Patterns • Circular Pattern dialog box • Placement • Creation Method • Positioning Method • Flip

35. Exercise 4-6 • Creating Rectangular Patterns

36. Exercise 4-7 • Creating Circular Patterns

37. Exercise 4-8 • Creating a Pattern Along a Nonlinear Path

39. Checking Your Skills • True__ False__ When creating a fillet feature that has more than one selection set, each selection set appears as an individual feature in the browser. • In regard to creating a fillet feature, what is a smooth radius transition? • True__ False__ When you are creating a fillet feature with the All Fillets option, material is removed from all concave edges. • True__ False__ When you are creating a chamfer feature with the Distance and Angle option, you can only chamfer one edge at a time. • True__ False__ When you are creating a hole feature, you do not need to have an active sketch. • What is a Point, Center Point used for? • True__ False__ A part may contain only one shell feature. • True__ False__ The only method to create a work axis is by clicking a cylindrical face. • True__ False__ You need to derive every new sketch from a work plane feature. • Explain the steps to create an offset work plane. • True__ False__ The options for creating work features filter out geometry that is not valid for the selected option. • True__ False__ You cannot create work planes from the default work planes. • True__ False__ A UCS can only be placed on existing geometry. • True__ False__ When you are creating a rectangular pattern, the directions along which the features are duplicated must be horizontal or vertical. • True__ False__ When you are creating a circular pattern, you can only use a work axis as the axis of rotation.
