Hi:
Ive been doing a bit of research on this subject as well. My findings: There appear to be four sources to convert SU 3D to 3D for viewing by othgers, clients, etc. The SimLab option that someone else mentioned at around $100. Very simple to use and the fact that anyone who has a recent Acrobat reader (8 or later, I believe) can rotate the model, turn on or off lighting, do basic measurements, etc. Nice and simple, but not many bells and whistles. eDrawings has a viewer, (free) and pro at around $100, that has more options, but requires a eDrawings viewer (which can be packaged into a single executable). Al Hart's (and associates) iNextRender has one that is attached to their render machine, I believe. Finally, Hypercosm which has a free and pro (around $200. This also requires a viewer or a player, but the viewer can be downloaded fro free as an applet for your browser. Hypercosm Pro, though not recently updated (I think) is the most sophisticated, permitting a 'client' to do more re viewing options.

Hope this adds to your dilema!
