Class Description

Class NURBSCurve.

Description:

This class defines a dependent blend curve. A blend curve connects the specified end of one curve to the specified end of another, blending the curvature of the parents to create a smooth curve between them. Methods are available to get/set the parent indices and ids, to get/set the ends of the curves used for the blend, and to get/set the tension values used.

All methods of this class are implemented by the system.
