thank you andy for your advice. I can get the vertex->create-convex to work on my one model and now I see what you mean about the concave vs convex. the create convex wont shrink wrap! I tried the other sketchup conversion I had that I sliced the baloney longitudinally, but the vertex-> create-convex gives me an error (see attached) I tried its advice, and it removed 95 vertices, but it still wontvertex->create-convex.

Also while I have your ear, another annoying problem I run into it when I try and combine surfaces (the 'c' command under surfaces control) I occasionally get the error about surfaces need to share a vertex (see other attached) but near as I can tell they do. Any advice on why I get this message? TIA- jleslie
