Hi, I encountered an issue with zones. For some reason it won't measure the area with roof substraction in the right way. For test I made a small building with two identical floors. One has only slab above it, and the upper floor has roof. Area of both is the same while the upper one should be smaller. It seems that I've done everything, yet it won't work properly. I put screenshots in link underneath. Any ideas?
Well... It looks like not too silly. At first, when I read your answer I asked myself how can one be so stupid. And so I came back to my file, turned on floor view, selected my zone, clicked design>connect>trim to roof/shell, then selected my roof aaaand... still nothing. But I guess it's no the way of trimming zones? I feel so embarrassed with these kind of question but this happens when people learn programs on they own jumping from one aspect to another, leaving some important stuff untouched.
No, it isn't. But only because you drawn the line from my lower zone to the roof. In between them is the second zone, at the height of the upper floor. I've put the roof down so drastically so the difference between area will be obvious. And as you cas see, the distance between default upper floor and the roof is far less 1400mm, so at some point there should appear 100% substraction.
