Hello all,
I create a schedule in order to have the surface for each material. But when I calculate the surface manually I have other result than revit.
In the attachment you will find the schedule. For example for the number 1. I have 1.42*3.0760=4.37 and not 4.15m ^2. In the second attachment you will find the structure of the wall.
P.s. the wall doesn't contain any opening.
Thnak you in advance!
