I guess you'll have to count me as one of those "poor modelers" then. Pretty much all my models for commercial purposes are converted into that file format for both technical and practical reasons. Shonner, you're not really hurting my feelings, but you are damning a lot of us professionals, and this would either make us mad or make us think that this was a reasonably ignorant statement. However, I do not want to get into any kind of flame war - I hate those and so I'm ending my comments here. My intent was only to try to help croxie, and help anything having to do with sailboats.
