VS:NurbsDelVertex

.VectorScript|VectorScript ..VS:Function Reference|Function Reference ..VS:Function_Reference_Appendix|Appendix

Description

Deletes a point in the referenced NURBS curve or surface. The function deletes the index2 point of the index1 piece for nurbs curve or it deletes an entire index2 row (index1 = 1) or column (index1 = 0) of points.

PROCEDURE NurbsDelVertex(
             objectHd   :HANDLE;
             index1     :LONGINT;
             index2     :LONGINT);

def vs.NurbsDelVertex(objectHd, index1, index2):
    return None

Parameters

objectHd		HANDLE		Handle to NURBS curve or surface.
index1		LONGINT		V-index of point in NURBS surface. The index is zero based.
index2		LONGINT		Index of point in NURBS curve, or U-index of a point in NURBS surface. The index is zero based.

Remarks

This function will work for both nurbs curves and nurbs surfaces.

VS:DelObject should be used to completely remove a NURBS curve or surface from the drawing.

There is also a bug in that VW does not redraw properly after a NurbsDelVertex call.

Create a simple nurbs curve, run it, and double click the pan tool to see it working:

NurbsDelVertex(FSActLayer, 0, 0);
