"That's not the point of it at all but with Modo's new retopology tools you could easily create a more manageable mesh from that 10 million poly object and open that as a nurbs surface in Moi to add details."

True, if we are using it as a control cage.

I'm just waiting for something that will do this with very high poly objects so we can have high detail in a nurbs object. Its clear that there are no tools in the nurbs world (ie. ZBrush) for pushing around surfaces like they were clay, but if anyone is aware of something that can do this now, please clue me in.

I have also come across limitations with polygon models and machining, and its not the polygon format that is limiting, its the knowledge of the people in machining about the polygon format, but that's a whole different ball of wax.
