They have Max, Softimage and lightwave at my job, but they are just to complicated. Then a coworker handed me the Beta version of rhino and I was hooked. Bought the full version and I just love it. It is a nurbs system. It works flawlessly on W NT 4 and W 2000. And the processes involved to model are so easy to pick up you'll be moldeling in a week. Xurge
