CADability dotNET
Assembly: CADability (in CADability.dll) Version: 1.1.4254.24737 (1.1.*)
Returns the point and the two derivations of the suface in a single call. It returns the same result as calling
PointAt(GeoPoint2D), VDirection(GeoPoint2D) und VDirection(GeoPoint2D) succesively but is often faster
than the three seperate calls.
