I am trying to make a CAD file to a Revit model, i try to use an outside wall which is made out of different materials (insulation, air layer, and facing brick). It is important that de facing brick is on the outside and the insulation on the inside of the wall. It seems that Helix can’t see what needs to be in-or outside and it orientates every wall the same. This makes it that the wall on the bottom of my plan and the wall left or right is the other way around. Any ideas how i can fix this? (already tried looking in type parameters but i don’t seem to find anything usefull)
