Next, any surface must be defined by several curves, and not just one. You could chop the curve up into seperate pieces and then create six planes from that, but I fail to see the difference between that solution and a nurbs cube primitive. I'm guessing that you'd like to create a cube that is covered by a single surface, and not the six stitched together as is the case with the cube primitive.?? If so, then I guess you could just make a nurbs sphere and tweak that into the shape of a cube. It'll just need some playing around to get the cv's into a position that gives you nice edges and nice corners at the same time. Whatcha making?

Use the polygon primitive... __________________ Chris (formerly R@nSiD) Twitter When the power of love overcomes the love of power the world will truely know peace - Jimmy Hendrix Winner SM VFX Challenge 1 3rd Place SM SteamPunk Challenge (May 2007)

Maybe that helps to your guys search for the solution to my problem. Greetings Brecht Edit: I was a little wrong about this: When I create a 12 subdivision cylinder and then use extrude face the extrusion comes nice together with the lines of the unextruded part =p. When I create a 20 subdivision cylinder there are more subdivision in the extruded part, but I don't know what's wrong, I guess less subdivions or something like that, anyhow, you guys are the pro ones.
