When I am creating a schedule for measuring masonry on a project, Archicad 25 multiplies the walls that have windows or doors! When I measure these same walls for the exterior finishing, the information is correct either if I have windows or not. See below the example. Thank you!
The schedule settings are below. I found out that if by chance the window/door is in front of another wall, and this one connects with our own window's wall, this one gets affected too. I added IDs to each wall so we can understand better what is correct or not.
