I think I am stuck with a room schedule for a multistory residential building (http://archicad-talk.graphisoft.com/viewtopic.php?t=23432 ). I can create room schedules for each apartment type in the 'unit plans.pln' module-generator file, and I can create apartment schedules with the lists and rentable areas of all the apartments in the 'building.pln', but I can't create a room schedule for the whole building because of overlapping zones (the zone with the overall rentable apartment area in the building file, which also has the apartment number, and the room zones within the hotlinked unit plans).
So the way to go would be publishing the (50?) apartment type room schedules from the 'unit plans.pln', and the apartment schedules from the 'building.pln', and linking everything in Filemaker (which I never used), right?
