Class Description

Class NURBSCurve.

Description:

This class defines a dependent iso curve. U and V iso curves are dependent curves created along lines of constant parameter value of a NURBS surface. Note the difference between "Iso Lines", which are a display artifact, and "Iso Curves" which are the dependent objects. There are methods available to get/set the parent surface index and id, get/set the direction of the iso curve, and get/set the parameter which determines the location on the surface the curve matches.

All methods of this class are implemented by the system.
