VectorScript: Detect self-intersecting polygon/polylines in General Discussion Posted January 15, 2017 Hello, all. Looking at the VectorScript function reference I see no functions that could tell whether a given polygon/polyline is self-intersecting. The only function that is told that it Quote "... Should remove self-intersecting segments from the result. ..." is the VS:OffsetPoly. But I don't want to see if a polygon/polyline is self intersecting as a side effect of an operation that actively acts on the selected object but just a read-only operation whether it is self-intersecting or not. Any suggestions are welcome.
