Sorry if this is a newbie question, but I did not find the answer in the manual or my forum searches.

When working with a triangle mesh object, is there a way to flag a triangle poly edge as hidden/visible? (in order to turn off display of interior edges)

Just like OpenGL's glEdgeFlag command. I know the 3DS format supports this flag per edge as well.

I'm trying to make an object that I can export as 3DS (or something other format that also supports this) so that only the boundary edges of the wireframe are visible when displayed with OpenGL in wireframe mode.

Let me know if you need additional explanation of the type of feature I am looking for.

Thank you in advance.
