I used the HLRBRep_Algo to create a 2D view of my shapes. I was able to get the single edges (TopoDS_Edge) from the HLR. Now I need to know the geometric type of the edges, if this edge is a line, a circle and so on. How can I do this? I think all the edges should be Geom2d_Curve or Geom_Curve type. I tried the Brep_Tool::Curve and Brep_Tool::CurveOnSurface, but none of them did work?
Does anybody know how to obtain the geometric type from the HLR edges?
Thanks for any advice,
