I think I'd have more luck mastering the Vertex room than mastering Amapi..LOL... I know a guy who swears by Amapi, and he works for a major multimedia firm, they use 3DStudio Max and Lightwave, and he still uses Amapi for a lot of his modeling... There's one thing for sure, Rhino and the New Amapi both give a serious run for the money when compared to programs costing 8 times as much. The big companies could learn something form programs like these, and that is, that you can make a serious high end modeler for less than $1,000. It all comes down to taste, preference, budget, and what you are comfortable using. kaom
