TrimNurbsSurface

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

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

Remarks

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

Examples

PROCEDURE Example;
VAR
	surfaceH, curveH :HANDLE;
	bFlag :BOOLEAN;

BEGIN
	surfaceH:= CreateNurbsSurface(3, 3, 1, 1);
	NurbsSetPt3D(surfaceH, 0, 0, 0, 0, 0);
