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 transcendental parameterization like spheres, cylinders, and cones.
