Mesh external edges

[Anonymous]

Hi!
I am trying to draw only external edges of some mesh. I.e. we have a triangulated quad, that consists of 2 polys. But i want to draw only 4 edges except diagonal. I tried to do it through edge management functions, but iterating with i=0..GetMeshEdgeCount() returns edges of all polygons in mesh. How can i get only external edges?

It sounds like you want something like edge flags from 3dsmax? Some edges are marked as hidden, so it shows
a triangulated model as quads instead of triangles?

I don't think FBX stores that kind of information.
