"Easy to learn"? "Loads of Tutorials"? Modellers are not "easy to learn". That's a simple fact of life-- what's going on as you try to take your 3D creativity and apply it through 2D interfaces is simply going to take some getting used to. No one does good work in any modeller right off the bat. The reason that so many folks use Rhino is that its powerful, and its robust. Many modellers fall down on certain aspects of functionality--weird results with booleans is a common one. I haven't done anything much in Amapi, but I can say that learning Rhino will serve you well for industrial design, as well as animation. But there's a learning curve. Amorphium is a great product, IMO, and the learning curve is not nearly so steep. Not something to be used for precision industrial design, but easy to use, fun, and will deliver nice models for Carrara and so on. . .
