do we have to connect all the doors and all the buildings and all the elevators, etc together or can they come in all at once. I see that you're mentioning unity 3-D but not sure if this can work on 3D game studio
I'm not sure what you actually asking about, but in Acknex, you need to set script (action) to each object separately via WED, so they have to be separated models, and this has nothing to do with models itself, but with the work flow (the way that Acknex works).
Edit: yertari sorry for offtopic.
