3D polygons

[Hans Jakob Muller]

Is there a way to trim, clip or subtract points from a 3D polygon or number of 3D polygons without deleting single points one at a time? Especially interesting if you want to make a rectangular terrain model from an irregular set of elevation curves (3D polygons)

upon returning... 'viola' all the nasties will be gone.
