Thanks Stefan,

my question was maybe unclear: I want to do the conversion from OBJ to NURBS, but want sharp corners inside for instance a Ring of polygons (just as a simple example, my real objects are more involved):



These are four polygons (a cube with top and bottom removed) and one sharp edge. I have not found a way in MoI to "disconnect" an edge like that so that the script can treat it as "sharp".

But somehow I feel it would be even better if we would not have to disconnect the pieces for sharp corners but could simply select the edges we want sharp and the script would work from there. The disconnecting has some disadvantages that I guess would be easier to solve with selected edges instead, since you would still have a whole, connected mesh.

I looked at the script but the math is over my head, so I can't directly contribute other than with some brainstorming on possible approaches and workflow.

Cheers and thanks!

Tom
