3dsMax Vertex Weld Problem.

Hi!
I have a strange problem with welding vertices in 3ds max.
Here is the video where you can see the problem.

The scene can be downloaded here(Max 2011).

Did someone knows why this happens and how to solve it?

Looks like the mesh is double-sided. Editable Poly works under certain topology rules that prevent welding two polys back-to-back. Detach the backfaces to another element, and it should work.

The problem was that the faces was flipped.

Another reason why Backfaces should be turned off by default.

yeah with nitrous enabled in shade mode it is really hard to see which is flipped and not. In dx mode you can see clearly. Thats a nice idea Eric.]Is there a script to flip all the normals in the same direction even if there are faces flipped in the wrong direction and some in the wanted direction? Edit: Nevermind found one

I remember when stuff like that always happened to me when modeling in Max and it would set me back forever. The other thing that still gets me is when the verts just disappear into La-La Land and you have to fiddle with the display settings, and reset the program 4 times over.
