Haha wonderful. I knew there had to be an easier solution than writing and debugging (oh the debugging!) it myself.

An external library? Or is there a utility class in Mason that I just missed? GeoMASON uses JTS which, in turn, has a variety of convex hull algorithms available. Cheers, Mark -- [log in to unmask]
