Hi. I make a face object made of lots of edge. I want to calculate normal vector to each edge. In my opinion, To caclulate it, maybe need the information about the each edge direction or vector. so I use the TopExp_Explorer class.
for(a.Init(TopoDSShape, TopAbs_Vertex); a.More(); a.Next())
TopoDS_Shape CurrentShape = a.Current();
so. I Get the CurrentShape. But I don't know how to convert TopoDS_Vertex to gp_Pnt.
If there is no way to convert, would you suggest a idea ?
have a nice day
