Is there a NURBS surface representation of this surface.
RhinoCommon (in RhinoCommon.dll)
public int HasNurbsForm()
Public Function HasNurbsForm As Integer
0 unable to create NURBS representation with desired accuracy.
1 success - NURBS parameterization matches the surface's
2 success - NURBS point locus matches the surface's and the
domain of the NURBS surface is correct. However, This surface's
parameterization and the NURBS surface parameterization may not
match. This situation happens when getting NURBS representations
of surfaces that have a transendental parameterization like spheres,
cylinders, and cones.
