Nope…the material takeoff area calculations are based on the center line of the wall…
I did a second test but the result is the same…the interior and exterior material are with the same areas….

I uploaded the “Area test.rvt” file and u can download it here:

thank U in advance!

Ah yes, This is tricky. You have a few options. you need to be sure what side your materials are on. When you do this with walls it works ok. If you make generic models then it does not work as well. Also how your walls join makes a big difference.

Hope that helps.
