Perhaps the issue here is with the never ending battle between Convex and Concave. If so, how can you get a Concave model to appear in GS6 as a Convex model would? I need to preserve all the detail I can. I have even tried VERY simple booleans consisting of two cubes, and that is still invisible to WED. The model I finished is a fairly complex Wheel Chair with spokes and metal framming, all done in MAX.
