Surface.Patch API Failed

Hi,

Do you have any ideas on this subject? I have been dealing with this problem. The polycurves that I would like to transform into surfaces are indeed closed, but API does not allow me to carry out this operation.

Can you post your code, and the error message? It may be a simple typo of Surface.ByPatch(closedPoly).

I don’t know anything. I found a solution: I converted it to mesh and then got the mesh edge as transforming the face.
