Summary0030519: BRepCheck_Edge fails on degenerate edge
DescriptionConstructing an edge and marking it as degenerated fails BRepCheck_Edge::CheckPolygonOnTriangulation. The edge lacks a curve because it is degenerate, and because it's not attached to a surface, the call to:

  aBC.Initialize(theEdge);

throws an exception. However, I don't see why the check is necessary for a degenerate edge. Simply adding

  if (BRep_Tool::Degenerated(theEdge))
      return BRepCheck_NoError;

to the top of BRepCheck_Edge::CheckPolygonOnTriangulation.
Steps To ReproduceCompile and run the example code.
TagsNo tags attached.

I realized my flawed understanding of degenerate edges. Could this issue be closed?

Dear bugmaster, I think it can be closed.
