You can press F to just build the floor of the selected segment, and M to build the walls.
I think you can build just the ceiling aswell... but i haven't tried this.

There is one complex method you could do.
Download the free modelling program anim8or.
Import the 3ds max model.
Search google for "anim8or .x" and click on the first link, it directs you to a script to export to .x
This only exports the model, not the animations, but it might work.
