Description

Trims the NURBS surface by a given NURBS curve.

FUNCTION TrimNurbsSurface(
              surfaceHandle   :HANDLE;
              curveHandle     :HANDLE) : BOOLEAN;

def vs.TrimNurbsSurface(surfaceHandle, curveHandle):
    return BOOLEAN

Parameters

surfaceHandle		HANDLE		Handle to a NURBS surface to trim.
curveHandle		HANDLE		Handle to a NURBS curve for trimming.

Return Value

Returns TRUE if trimmed the surface, otherwise returns FALSE.

Remarks

It returns true if the curve is attached to the surface as trimmed curve.

Example
