There is no easy, out of the box way to get zone areas both with and without plaster area in Archicad. You could achieve it by modeling the plaster walls as separate simple walls and setting them up to reduce the room area. But to model all plaster manually instead of using composite materials is horrible! With the Room Coverings Add-On you can automate a big chunk of that modeling work. In this post I’ll demonstrate how to use the Add-On to model the separate plaster walls automatically and how to get the room area with and without the subtraction of the plaster area.
Step-By-Step Guide
- Setup a room with
Construction Method: Inner Edge
- Setup your plaster wall with
Relation to Zones: Reduce Zone Area Only
and store it as a favorite - Use the plaster wall for the wall settings in the Add-On palette, select the zone and execute
Add Room Coverings
- Update the zone with
Design -> Update Zones...
- Finally setup the zone stamp to display the different area values. The area subtraction due to the new plaster walls happens between
Measured Net Area
andReduced Area
. You can check the details of the calculation in theAREA CALCULATION
section.

Result
And here’s the resulting zone stamp displaying both reduced and non-reduced room areas:
Calculation Note
There’s a zone calculation setting in the project preferences which has an effect on this calculation. To get the most accurate calculation, you can decrease the lower limit for Wall Subtraction
to 0.00 m²
as shown in the following screenshot. You will need to update the zones after changing this setting.
