I’ve recently started using Maya, and was trying to model a house.
I built what looks fine to me. I have used boolean to cut the doors and walls out, but when I export, the objects I used to cut the doors and windows are still there.
The holes have also not been cut, even though they are cut in the model in maya. Is there anyone who could offer some advice as to what my trouble might be.
Have you deleted all the history on the model in maya before exporting?
Well, that fixed the booleans still being there. Now I have another issue, lol.
When I clear history, and export (fbx), then import as asset to unity, most of the walls are missing huge pieces.
Maybe I cleared to much history or something? I tried cleanup and copying the mesh, neither fixes it.
Before I clean history, all the walls, the boolean objects, everything is there.
After I clean it, the booleans are gone, and half of the walls too. Ugh. I’ve tried rebuilding it different ways. The first time I made it from a single plane object, tracing out the floorplan.
I would then extrude the object and have my walls. If I tried a boolean the whole object poofed. I read that booleans and planes don’t get along.
I then made it from a single cube object. I followed the same process as I did with the plane, minus extruding up. It wasn’t much different, besides having to merge 2 extra vertex when walls met.
Yeah personally I wouldn’t use Boolean operations for game content.
Here is an old posting about the exact same issue, it might be helpful.

Never use booleans for any work, if you asked me. They lead to way to many extraneous verts, and the amount of cleanup required is never offset by the speed at which you beat the boolean operator into submission to get the results you were after.
Extrude your walls up from the floor plan, and then insert edges and delete faces to get the doors and windows in position.
Thanks for the advice guys. I’d just about resigned myself to giving up on Booleans on my own. It seemed like any tip I found (use cleanup, copy delete mesh,etc) fixed one problem and made another.
That post at http://forum.unity3d.com/viewtopic.php?t=2124&highlight=boolean+maya was/is my exact issue. I’m gonna give up on booleans too, the time I spent trying to clean up one wasn’t worth it like you said.
I was just hoping I had overlooked something simple like, “Oh man, you just gotta press F9 + F7 first” or something goofy. 
I use booleans for simple window and door holes in walls. Maya booleans are polygonal trickery (voodoo, witchcraft, whatever). Just triangulate the faces you subtracted from after boolean and you should be fine.
