expression-based property and zone area

Vaa — Thu, 28 Aug 2025 06:30:14 GMT

Hi everyone,

I’m trying to set up an expression-based property in Archicad that automatically labels apartments depending on the size of a zone.

For example, I would like the property to return “2-Bedroom Apartment” if the zone area is within a certain range (say 70–90 m²), otherwise leave it blank or return another label.

I’ve tried using an IF statement like this:

IF ( AND ( {Property:Zone/Measured Area} >= 70 , {Property:Zone/Measured Area} < 90 ) , "2-Bedroom Apartment"

It seems straightforward, but I’m not sure if I’m referencing the zone area correctly, or if there’s a better way to handle ranges and apartment classification.

Has anyone set up something similar, or can point me in the right direction? Ideally, I’d like this property to show up in schedules so that each apartment can be categorized automatically.

Thanks in advance!

You must specify the unit here m2 and add the value false
Try with this formula

IF ( AND ( {Property:Zone/Measured Area} >= 70m2 , {Property:Zone/Measured Area} < 90m2 ) , "2-Bedroom Apartment" , "")
