So, this is the problem: In a composite wall, depending on the position of the reference line, the wall area measures incorrect when I do ITO's in Solibri 9.9. compared to Archicads own ITO's.
Depending on where the reference is placed to get a somewhat correct area is not a good solution!
Is it a way to calculate the area of (any composite object) a wall in this case, based on the skin-definitions (finish, core, other), combined with whether it is outside or inside, to ensure a somewhat reliable result?
