SheetCam does not support NURBS curves internally. When it imports a drawing, all non-circular curves are broken down into lots of very small line segments. It then does arc matching on those line segments and any other line segments in the drawing before finally merging any ludicrously short line segments. You can specify the tolerance for arc matching and line merging.
I have no intention of adding NURBS functionality. Only a few controls support it and the maths involved in generating robust NURBS offsets is far beyond my capabilities.
