Rhino is an excellent modeling app for just about anything. Often used in films as a way of scanning character maquettes or for creating things like the Goblin Glider, Rhino has taken an undeserved back seat to some of the bigger name apps. When it comes to nurbs, no program on the market has Rhino's ease of use and support. Purchasing Rhino will give you access to the development staff and even the owner of the company Robert McNeel, who is always willing to talk or lead you to someone for help. Top that off with an upgrade plan unheard of. If you've purchased Rhino this year (before DeC15th) you can upgrade to version 3 when it comes out in January for Free! Modeling in Rhino is just as friendly. You can literally jump in and have a model that's respectable on your first try. With the addition of handlebar tools and point wieghts, Rhino also makes an excellent organic modeling tool. It supports a wide variety of formats for both importing and exporting and if you export as a mesh, it has a great nurbs to mesh converion tool and a polygon reducer built in. With it's new plug-in architecture (introduced in 2.0), Rhino the sky's the limit for what the future holds!
