The properties of Bézier surfaces, such as the rectangular patch structure and local behavior, are quite similar to those of B-spline surfaces. The Bézier surfaces are created in the same way as B-spline surfaces, using one of the SURFACE menu commands to produce the surface according to the type of projection and section curves.
The main difference of B-spline and Bézier surfaces is with the local editing functions. Unless you wish to edit Bézier surfaces locally, you won’t have to worry about the difference between the two representations.
Some demanding computations, such as surface intersections and blends, require the surfaces to be in Bézier form. When necessary, DeskArtes automatically converts the surfaces from B-spline to Bézier representation.
