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.

maybe this is the script of conversion into nurbs inside freeship, but I'm not sure..

Fusion360 T-Splines is also a good converter from mostly quad meshes to nurbs. There's a free commercial license available as well provided certain criteria are met.

What is your start format ?

Maybe free PolyCAD alone makes that! ;) http://www.polycad.co.uk

Imports STL, WML... (not OBJ existing)

And Export IGES to Moi

not yet found the complete workflow...
but i have yet that in Moi ;) Not Yet surfaces...

Hi,

we had this discussion already.

Totally missed this one and what was the last solution found ?

The last solution for me was to use Max's subd script and ArtForm's merge command,
to get larger and fewer patches. Or one has to use the free Fusion 360 T-Splines solution.

I don't desesperate to find something with PolyCAD! :)
