What 's the rule for judging the wall's Zone Name

[Anonymous]

The wall is connected with "Zone F" and "Zone G". The reference line is adjacent to the Zone F. I want to figure out what is the rule for the "Zone name" shown in the Wall schedule.

As I will calculate the surface area of several walls around one zone instead of all the walls around the zone. Any ideas for filtering the wall out?

I don't think there is a schedule field that would return a correct value for such a case. ArchiCAD is not prepared to return such a value.
In case of Doors/Windows, you can list in the schedule the Room from which it opens and the Room it opens into. But there is no such option for Walls.
