overlapping edges of model

I’m not sure if this is something I need to fix in 3DS Max or Xith. When I load in the following .3ds model, I have two aligned objects, but one will show through the other. See picture below:

I’m guessing that when I align two planes, they share the same space, so the renderer does not know which one to show. It basically flickers between the blue and red textures when I move the view around. If this is the case, how do I get the edges lined up one against the other but not overlapping? I tried moving the objects away from each other just a tiny bit but I still get the same effect.

I do not have much experience with 3DS Max, I’m just familiar with the basics.

Any help is appreciated, thx. Sorry to dirty the Xith forum if this thread is unrelated, I wasn’t sure where to put it ::).

if i just connect edges to edges and not edges to faces it seems to work fine. i guess that’s the problem.
