Insted of obteining just he remaining polygon i get some thin portions from the original polygon as part of the corect polygon. The problem might appear because the polygons are in space?I've tought on using a 3dbuffer for the clippers but for a polygon 3dbuffer extends the polygon along its normal vector, isn't this correct?. Any sugestions??
If i clip 2 polys with same width but different length, i get no slivers but correct overhang.
Even if force them to 3D with zero or different elevation it clips correctly.
I even angled the surfaces in space, stil correct result.
If they are in same plane, but not the x,y plane, maybe u could project em to that plane prior to clipping?
(i still am using 2012 FME)
