Good time of the day, gentlemen
The window setbacks should only be taken in account in the zone area calulations when they reach the floor. Otherwise, that space isn't available for use and, therefore, it isn't calculated in the zone areas:
In case if the window reaches the floor, the setback has to be calculated if it's deeper than 130 mm, though:
In the project in question the floor consrtruction, however, consists of two main parts - carrying reinforced consrete slab and the finish floor construction. The tops of the reinforced concrete slabs coincide with the floor levels.
In this situation, when the zones are created automatically, the window setbacks don't get calculated. Is it possible, somehow, to still calculate them, despite such floor level settings?
