To Edit the Surface Properties
1. Click Mathematical Properties and select a surface or component. The Properties dialog box opens.
2. View and modify the surface type, the degree of the surface, and the number of segments in the U- and V-directions.
The Bezier and B-Spline surfaces can have a maximum value of 15 for the U- and V-degrees.
A B-Spline surface with two segments (params) in both U- and V-directions is a Bezier surface.
You can modify the surface properties of any analytical surface that does not have multiple components. After modifying the properties, this surface becomes a polynomial surface.
