Link zone

[Sere]

Hi, is there a way to show the area of one zone in another zone tag?

Eg to show the balcony area into the apartment zone tag, linking them via the apartment name.

I think I am close but I don't know how to formulate it correctly:

I created a new parameter 'Balcony' an I would like to add an expression to say "IF the apartment name is the same, show the balcony area"

Not as far as I know.

There is no relationship between zones.

Years ago, the only solution I could find for this is go use GDL scripting and Text File operations.

In your case, the Balcony zone would write its data to a text file, then the Apartment zone would read that data from the text file.

But that requires GDL knowledge.
