what about my suggestion above?
Ben, your diagram is really helpful. I have a similar situation, and I'm not sure if it applies to my case as well.
I have a project with 3 separate buildings (5+5+4 unit 2 story townhouses). Of course, they will share a lot of common details. There is about 5 different unit types, but they are slightly different also, depending on where they are on the building (edge or middle).
It seems that because of these slight differences and limited number of repeating units, it might be better off for me to model each building w/o the use of "unit" modules.
Since there are three buildings however, I am thinking of doing each building as a separate PLN file, and bring them into a site PLN file, because the building orientations in the site plan are different from how I'd like to show each floor plan.
I'm not sure exactly however, where to do the "documentation" portion - text, dimensions, etc. Also, in which file should I do the detail call outs & details? Should I hotlink the buildings as modules or PLN files?
