kaom, I know the feeling about the spline modeler! I've had many encounters with it! Unfortionately I don't have any tricks to get rid of that square shape either. I've found that surface fidelity really doesn't matter all that much either...I've created splines with the fidelity cranked up all the way to 10000% and they still came out edgey. I don't know if this is a bug in the programming of C or what's going on. You might want to switch the spline to a vertex model and subdivide and so on from there...Good luck to you! Nice looking wheel btw. I'm working on a car model myself...1957 ford the thing has WAY to many curves though!!! It's possibly the hardest thing I've ever modeled! Good luck to you!!! Jared
