Detailed Description

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.
