ok. Here are some pictures of the map in 3ds:

Here is an above view.

Here are the errors, they are "double faced" or "multiple edged", can you fix them?

Here is a side view, showing the bridges.

Here is the corridor, that needs a matching base to be added, well 2 identical bases, so its only making one.
Those are my images, plus i need a texturer to take textures off of the actual game level, with HMT and add it to my map. The textures are standard floor wall and ceiling ones.
