Here is my problem.
I need to trim a nurbs surface (of type Geom_BSplineSurface) with a set of trimming nurbs curve (of type Geom2d_BSplineCurve).
I have obtained the values for the surface and the trim curves directly from an open cascade shape, I have start with a rectangular surface with a circular hole in the center.
I have searched this forums and internet in general for a simple and complete explanation of the procedure to obtain the trimmed surface without success, someone
suggest the use of BRepBuilderAPI_MakeFace class, others suggest the use of BRepFeat_SplitShape or LocOpe_SplitShape classes, but I can't find a complete explanation of how to apply
Can anyone help me ?
