Hello,
does open-cascade already provide functionality to unroll/ flatten NURBS-surfaces? (Have a look at [1], [2] to see the functionality I am looking for.) If not I would like to add some functionality to occ. (mesh-based methodes [3], and a direct nurbs approach). But for this I would need some information on how to access derivatives of nurbs and there base-functions at discrete uv-points.

thanks for your reply.
I didn't know occ has something like this already build in. Can you inform me about the methods you are using for flattening surfaces?
nice regards
