Patch
Patch class
A Patch is a parametric modeling surface, similar to NurbsSurface, it’s also defined by two PatchDirection, the U and V. But difference between Patch and NurbsSurface is that the PatchDirection curve can be one of Bezier, QuadraticBezier, BasisSpline, CardinalSpline and Linear
public class Patch : Geometry
