Ok guys, need your help (and I'm sorry for my poor english, I hope you will understand my problem:)); I'm working with zones now and what I need is to get two measured values : "normal" room area and room area without wall finishing.Any possibilty to get it with one zone...? Many thanks for help!
It could be done with scripting the zone stamp. You might have to manually set a parameter for the skin thickness though. I suspect this information about the enclosing walls is not available to the zones.
I doubt you'll find one ready made to the purpose though.
