21 In this tutorial, you learned how to: Topics Covered 1.Creating an extrusion from a b-spline 2.Creating an extrusion using the extrusion tool 3.Creating an extrusion from a curve 4.Shading your model 5.Creating a fillet 6.Creating a chamfer

22 Best Practices Make sure that the working grid is changed Check entered values for the parts are correct Check location and orientation of parts/points Check that the parts are referencing the proper markers
