-class FuseEdges from BRepLib
-
- ---Purpose: This class can detect vertices in a face that can
- -- be considered useless and then perform the fuse of
- -- the edges and remove the useless vertices. By
- -- useles vertices, we mean :
- -- * vertices that have exactly two connex edges
- -- * the edges connex to the vertex must have
- -- exactly the same 2 connex faces .
- -- * The edges connex to the vertex must have the
- -- same geometric support.
