The Curve from BRepAdaptor allows to use an Edge of the BRep topology like a 3D curve.
It has the methods the class Curve from Adaptor3d.
It is created or Initialized with an Edge. It takes into account local coordinate systems. If the Edge has a 3D curve it is use with priority. If the edge has no 3D curve one of the curves on surface is used. It is possible to enforce using a curve on surface by creating or initialising with an Edge and a Face.

| ) |
