2. Outline of class  1 st part: How to make sketches  Entities  Relations  Dimensioning  2 nd part: How to make features  Starting/ending points  Different kind of features  3 rd part: practice

3. Things that can be sketched  Line  Rectangle  Slot  Circle  Arc  Polygon  Spline  Ellipse  Chamfer/Fillet  Offset  Trim

4. Line

5. Click on the line symbol

6. Line Options  As sketched  Horizontal  Line will snap to be horizontal  Vertical  Line will snap to be vertical  Angle  Will define the line based on an angle  For Construction  Will be used as a hidden line  Infinite Length  Line is infinitely long

7. Rectangle

8. Rectangle Options  Corner Rectangle  Assumes a horizontal rectangle  Center Rectangle  Assumes horizontal  3 point corner rectangle  Chose 3 points for the corners  3 point center rectangle  Chose two points for a center axis  Parallelogram  3 points for a parallelogram 8

9. Slot

10. Circle

11. Arc

12. Polygon

13. Spline Start clicking

14. Edit Spline  Adjust arrows  Change slope of tangent  Add points (open spline tools)  Chose ‘insert spline point’

15. Ellipse 1.Define center 2.Define major axis 3.Define minor axis 15

16. Chamfer 16

17. Fillet

18. Offset  Creates a copy of selected sketch entities a certain distance away 18

19. Trim  Power Trim  Trim all entities the mouse moves over  Corner  Connect two lines  Trim away inside  Cut lines passing through two entities  Trim away outside  Cut lines extending past two entities  Trim to closest  Cut the entity up to the next closest entity 19

20. Sketch Relations  Relations add geometric constrains to the sketch entities  Relations appear in green boxes by the entities they relate to Horizontal relation  Horizontal/Vertical  Parallel  Perpendicular  Collinear  Coincident  Midpoint  Intersection  Tangent  Coradial  Concentric  Equal  Pierce

21. Geometric Relations  Tangent Tangent Parallel Horizontal Vertical Intersection ConcentricPerpendicular

22. Geometric Relations (These can be added automatically via hotpoints)  Horizontal  Straight left to right  Vertical  Straight up and down  Parallel  Lines side by side and having the same distance continuously between them  Perpendicular  at an angle of 90° to a given line  Coincident  Coincident points will lie on a line/curve  Midpoint  Point will at the center of a line/curve  Intersection  Point where two lines/curves cross  Tangent  a line that touches a curve at a point, but if extended does not cross it at that point.

23. Geometric Relations (These can only be added manually)  Coradial  Two arcs with the same center point and radius  Concentric  Two arcs/circles with the same center point  Equal  The driving dimension for the entities are equal  Length  Radius  Pierce  When there is a coincident reference to a different sketch  Symmetric  Add some symmetry about an axis/centerline

24. How to constrain  Click ‘Add Relation’  Select entities  Make the relation

25. The Status of a sketch  Under defined  Fully defined  Over defined

28. Creating Basic Features  Extrude Boss/Base Feature  Extruded Cut Feature  Revolve Boss/Base Feature  Revolved Cut Feature  Fillet, Chamfer  Dome Feature

29. Extrude Boss/Base Feature

30. Where to start the extrusion Where to end the extrusion Can extrude in a second direction Can extrude from a thin feature or a contour Add a draft to the part Can choose the angle of extrusion

31. From  Sketch Plane  The plane of the sketch  Surface/Face/Plane  Can choose any face  Vertex  Can choose a point for reference to start  Offset  Can enter a quantity to offset from surface

32. Direction 1/Direction 2  Blind  Extrudes a specified distance  Through All  Goes through all bodies  Up To Next  Extrudes to the nearest feature  Up to Vertex  Up to a specified point  Up to Surface  Can choose a surface to extrude to  Offset from Surface  Can set a distance from a selected surface  Up to Body  Similar to surface, but can choose a whole object (body)  Midplane  Extrude in two directions with the current plane set as center

33. Draft  You can use a draft to add an angle to the extrusion  Useful for injection molding

34. Contours Vs. Thin Features  2 Contours  3 Contours  Thin Feature 34

35. Thin Feature  One direction  Midplane  Two-direction  Sets the thickness of the extruded feature

36. Extruded Cut  All options are similar to extruded boss/base

37. Revolve Boss/Base Feature

38. Axis of revolution Where to end the extrusion Can revolve from a thin feature or a contour

39. Revolved Cut Feature

40. Fillet

41. Fillet Types  Constant Radius  Entire fillet has a constant radius  Variable Radius  Radius varies  Face fillet  Full round fillet  Rounds off bosses or ribs

42. Chamfer

43. Dome

44. Practice

48. Additional Stuff

49. Sweeping  Normal extrusion restricts your extrude to a linear path.  Sweeping is when you extrude along a path

50. Sweeping  In order to sweep, you need two things  Sketch profile  Path sketch  The path must start in/on the sketch profile.

51. Lofting  Lofting is when you have multiple cross sections, and the part extrapolates the extrude from cross section to cross section

52. Lofting  Need to make multiple sketches of multiple cross sections

53. Additional Stuff  Mirror  Patterns  Shell
