Trying to calculate ACTUAL Wall Areas

[jojojojojojojojojojo]

Hello! I dont really know where this topic belongs to, but I seem to have a very specific thing I need to do. I work in Iceland right now and in order to apply for a building permit, there you need to fill out a form not only for Gross Internal Area, Room Sizes and so on, but also for the qm size of the External Walls, with and without openings. I am not talking about the area they take up on the floor plan, but the literal area of their surface. very annoying.

In microstation and Revit there seems to be a feature like the Zone Tool that can also be used in 3d but im missing that in Archicad. The only way i can think of is to calculate this manually or to use the Fill Tool on every single wall... 

Can anyone think of a better idea? merci

Operating system used: Windows

Hi,

You can either recall that information
- in schedules by listing the Gross surface area of wall outside face (net or gross = with or without window openings)
- using autotext labels on elevations or on the floor plan directly, recalling the same function (gross/net surface area ...)
