SubtractPolygon

Description

Clips one polygon from the other.

FUNCTION SubtractPolygon(
				hMinuedPoly : HANDLE;
				hSubtrahend : HANDLE;
				dFuzz       : REAL): HANDLE;
def vs.SubtractPolygon(hMinuedPoly, hSubtrahend, dFuzz):
    return HANDLE

Parameters

Name Type Description
hMinuedPoly HANDLE
hSubtrahend HANDLE
dFuzz REAL

Examples

HMoveBackward (LNewObj, TRUE);
ClipSurface (LNewObj, objH);
HMoveBackward (LNewObj, TRUE);
objH3 := LNewObj;
tempobjH := SubtractPolygon (objH3, objH, Fuzzer);
IF tempobjH <> NIL THEN
BEGIN
	DelObject (objH3);
	HMoveBackward (tempobjH, TRUE);
import vs

# Clips one polygon from the other.
hMinuedPoly = vs.FSActLayer()  # handle to the first selected object on the active layer
hSubtrahend = vs.NextSObj(vs.FSActLayer())  # handle to the next selected object
dFuzz = 1.0

objHandle = vs.SubtractPolygon(hMinuedPoly, hSubtrahend, dFuzz)
if objHandle is not None:
    vs.Message('Created object handle: ' + str(objHandle))
