I'm sure this question has been asked. I have tried all the wall definition settings I can think of.
I made a new wall type. (Think post frame construction with horizontal girts. I have 4.5" wide "studs" at 96" spacing. I replaced exterior sheathing with Furring wood, 1.5" thick. I also have Furring wood inside, 1.5" thick. So the framing is 8.5" thick, plus siding and drywall.
I need my interior dimensions to pull from the interior Furring (Girts) No matter what I do, it pulls from the Studs.
But, when dimensioning the Exterior of the building, I need to pull from the Exterior of the "studs" (posts)
Please help me.
