GeometricObjects Interface CATPCurve

Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.

interface CATPCurve

Interface of the parametric curves defined in the space parameter of a surface.

A CATPCurve is then always associated with a CATSurface element. If the curve is parameterized by the function (U,V) = F(W), and the surface is parameterized by the function (X,Y,Z) = G(U,V), the CATPCurve is parameterized by the function (X,Y,Z) = G(F(W)).
