hi, i'm trying to refine a polygon shape I made, that actually consist of a bunch of triangular prisms. i'd need to know 1) a way to snap together proper, the merge edge tool has given weird results, so i reverted back to separated shapes and 2) a way to make the edges smoother, i tried using the crease edges tool and the subdiv proxy, but once again, weird things happened... any clue anyone? thanks.
