Sorry but I dont agree with Danny. because benefits of Nurbs technology is the accurate drawing. So we could take advantage of this accuracy. And especially this is capable for other real industries for example: in architecture, other mechanics, car industry etc.
I think it would be more important than others (entertainment; character modelling etc. opportunity ). There are many many subdivision software for other nonaccurate design opposite cad softwares where you dont find an complex , affordable and easy to use application (now I thought the architectural cad softwares, except vectorworks but it has some limitation in modelling and documentation).
