Do you like to draw? Are you better at drawing than using something solid, like clay? Then you are most likely a spline person. Rhino uses nurbs. But the way you use it is really more like a spline modeler. Hash AM is another good spline modeling program. I'm more of a clay type person. I can't even draw a decent stick figure. And drawing and joining splines like in Rhino makes my head hurt. So I like using programs like RayDream and Cinema4D. C4D also uses nurbs. But the approach is different. It's more of a subdivision method which is more like working with clay. You start with a box. Then cut it up, extrude here, pull there. Until you get what you want. Once you figure out which type of person you are. The modeling will come much easier. ScottA
