Thank you for the quick feedback. I am sure they will!
By now unfortunately, I get at runtime a System.MissingMethodException: ‘Methode not found: “Boolean Rhino.Geometry.Collections.NurbsSurfacePointList.UVNDirectionsAt(Int32, Int32, Rhino.Geometry.Vector3d ByRef, Rhino.Geometry.Vector3d ByRef, Rhino.Geometry.Vector3d ByRef)”.’
Same with NurbsSurface.UVNDirectionsAt.
I previously installed Rhino WIP and refered the correspondant rhinocommon library in my project. So I’d say it is all allright at my end. Looks like the library is still not complete there?
