Summary0026898: Chamfer result of Cone is wrong
DescriptionTopoDS_Shape aCone = // Load from ConeToChamfer.brep
BRepFilletAPI_MakeChamfer aMakeChamder(aCone );
TopoDS_Edge aCircleEdge = // Find the cone bottom circle edge
TopoDS_Face aBottomFace = // Find the planar bottom face
aMakeChamder.Add(2.0, 12.0, aCircleEdge, aBottomFace);

The result is valid, but it does not satisfy the input parameter dist1 = 2.0, dist2 = 12.0. It seems the result is dist1 = 12.0, and dist2 = 2.0.
