Moved from the 3D (generic 3D) to the more specific 3D Flash Animator Forum. I'm quite sure the 3DFA gurus here can definitely steer you in the right direction.
Put plainly, you're wrong, 3dfa does support moving true 3d models, quite well in fact, x,y,z plane all the way.............
....you should look into it before you add your comments. 3DFA is well ahead of what you're thinking. Best bet is to simply import a 3ds model, I assume you have 'max', and start seeing what is possible......
You must completely build the model as a 3d model, not a vector/bitmap...
and if your using action script to rotate the model, it must be exported as flash 9, which I am not very fond of at the moment. The transition between simple flash 8, and powerful, professional flash 9 is tough, but worth it...
