On Vista 64 Ultimate 6GB and IP7 2.6GHz a whopping 576 Solid pieces were converted into a 108MB .obj with 6456724 Polygons and 6467653 Point Count in less than 10 secs for screen display and saved in another 20-30 secs. More was not possible as that took 3.99GB Mem and a peppermint or polygon more would have caused a mess.

You're on to something Michael!!!
