Controlling Profile Edges and Extrusion
Use this procedure to specify the following parameters for a profile:
■

■
the axis along which an object is extruded from the shape of a profile
These settings determine how surface hatching is applied to objects created from the profile and how the objects are
extruded from the two-dimensional (2D) profile.
