About Subdivision to Nurbs.

Hi, I tried to use the script to convert the subdivision surfaces to nubrs surfaces, but some time ago I found a program that instantly converts the subdivision surfaces into nurbs pieces, it's another method and I was wondering if it could be examined in detail, maybe some genius here can make a version for Moi. The interesting difference are the generation of resulting surface, made in big patch, and some time with simple object a clean smooth surface..

Here some old link about this method.
