Jaager, thank you for the tips. The Heels are made in Rhino (yes NURBS :-) ) and I have some problems to export it in a acceptable size- exporting is not the best thing in Rhino I guess - but I have to say I'm on Rhino 1.0 - maybe its better in 1.1 or 2.0. Hehehe - no money right now to buy 1.1 ok, I'll see if I can change the Heels into a doublesided prop and I think I'll get it sized down. And... I have no problem with critics - Critics are the best way to get better :-) Thanks again Jaager Chris
