This is an unfinished experiment, but I'm posting some info now, as I don't know when I'll have time to play again :) Maybe someone will find it useful. Previously I posted a message on this forum to say that I was going to experiment with converting meshes to Nurbs and then using the ApplyMesh command in Rhino to make morph targets, say of the male face to the female face. Success was limited. I managed to convert meshes to Nurbs successfully, but each object ended up being several hundred surfaces, and ApplyMesh doesn't work too well with welded surfaces. However... This is the most amazingly quick and easy way to draw cross sections for lofting surfaces!! For the first time I am now able to simply draw a curve and project it to the exact shape of the anatomy. Great for making clothing, for example. I'm not sure if it is any big deal to convert meshes to Nurbs - The guys at Rhino seem to think it can't be done. So if anyone would like more info, or have some more ideas on the subject, please let me know. In the meantime I'll carry on when I have time. Berge
