what I meant was instead of trying to make the door all in one continuous shape like that, perhaps make just the lower door portion by itself, and have the upside-down "U" frame of the window as a seperate piece... and don't even worry about trying to make them look seamless.

Or, use polys and put holes wherever you want. lol You gotta remember, Maya isn't just a nurbs program... it's got a lot of other stuff in there, too.
