BRepAdaptor_Curve2d Class Reference

The Curve2d from BRepAdaptor allows to use an Edge
on a Face like a 2d curve. (curve in the
parametric space).

It has the methods of the class Curve2d from
Adpator.

It is created or initialized with a Face and an
Edge. The methods are inherited from Curve from
Geom2dAdaptor.
