From the building-tool context menu you can select the desired floorfile and import it.
The program will iterate thru existing buildings in the model and assign the corresponding height from the floorfile, if included there.
Since the floorfile contains the name and the floor amount of the buildings
and building names can be changed,
it will try to identify the buildings (for this we collect older building names in the building parameters) by the previous name. Therefore you should rename the building via AREAL naming option.
It mostly works well, but there may be situations, where the older name of the building is no more available.
