Description
Creates a group of lines which represent the weighted medial axis of given polygon.
FUNCTION OffsetHandle(
h :HANDLE;
offsetDistance :REAL;
EdgeRestoration :BOOLEAN;
FilletSharpEdges :BOOLEAN) : HANDLE;
def vs.OffsetHandle(h, offsetDistance, EdgeRestoration, FilletSharpEdges): return HANDLE
Parameters
h HANDLE offsetDistance REAL EdgeRestoration BOOLEAN FilletSharpEdges BOOLEAN
Remarks
(_c_, 2014.03.25): The routine was introduced undocumented by VW11 (2006).
Warning:
- The parameter offsetDistance takes mm, unregarded unit's settings.
- If you pass a polygon/polyline it outputs a group containing one or more polygon/polylines, not a group of lines.
- Polyline holes are ignored
- Undo fails on this action: you should consider carefully if using this routine
- VW 2011, 2012, 2013
- the handle h doesn't set. Use LObject to fetch the handle. This is dangerous, if the routine fails, LObject will be something else: store LObject before running the script and afterwards, then compare. If they are different the routine succeeded.
- VW 2014
- the handle will set as expected, undo still fails
Example
VectorScript
PROCEDURE try; VAR prevLObj, sourceObj, groupObj : HANDLE; BEGIN sourceObj := FSActLayer; IF (sourceObj <> NIL) THEN BEGIN { h won't set with OffsetHandle until VW 2014 } prevLObj := LObject; { only before VW 2014: store for later comparison } groupObj := OffsetHandle(sourceObj, -10, TRUE, TRUE); { negative offset -10mm } groupObj := LObject; { only before VW 2014: this should be now the product of OffsetHandle } IF (prevLObj <> groupObj) THEN BEGIN Message('Type: ', GetType(groupObj)); ResetObject(groupObj); HUngroup(groupObj); SetDSelect(sourceObj); END; END; END; Run(try);
