Detailed Description

Class NURBSSurface.

Description:

This class provides access to the 2-Rail Sweep Surface. A 2-Rail Sweep surface uses at least three curves. Two curves, the "rails," define the two edges of the surface. The other curves define the surface's cross sections. A 2-Rail Sweep surface is similar to a 1-Rail sweep. The additional rail gives you more control over the shape of the surface.
