Class Description

Class NURBSSurface.

Description:

This class defines a dependent lathe surface. A lathe surface is generated from a curve sub-object. It is similar to a surface created with the Lathe modifier. The advantage is that a lathe sub-object is part of the NURBS model, so you can use it to construct other curve and surface sub-objects. Methods are available to get/set the parent index and id, get/set the axis and amount rotation of the lathe.

All methods of this class are implemented by the system.
