Mastering CAD Basics: Extrusion, Revolve, Fillet, and More

1. Chapter 5Creating Basic Features

2. Features covered • Extrude Boss/Base Feature • Extruded Cut Feature • Revolve Boss/Base Feature • Revolved Cut Feature • Rib Feature • Fillet, FilletXpert, Chamfer • Sketch Text • Dome Feature

3. Extrude Boss/Base Feature

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

5. 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

6. 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

7. Draft • You can use a draft to add an angle to the extrusion

8. Contours vs. Thin Feature • 2 Contours • 3 Contours • Thin Feature

9. Thin Feature • One direction • Midplane • Two-direction • Sets the thickness of the extruded feature

10. Extrude Cut Feature • All options are similar to extruded boss/base

11. Revolve Boss/Base Feature

12. Axis of revolution Where to end the extrusion Can extrude in a second direction Can revolve from a thin feature or a contour

13. Revolve Cut Feature

14. Rib Feature • 1st make a new plane • Make either an open or closed sketch

15. Fillet/FilletXpert

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

17. Chamfer

18. Dome Feature
