I have built walls with composites, but of course want to dimension from the framing. When I try to do this, on the inside of the wall, I get no marker-change; it doesn't turn into a pencil w/ line or the lamda or anything. If I move to the Outside of the wall, I get the heavy lambda, but when I dimension it, I also get the wall thinckness recorded, which I don't want at all. When I go to delete just the wall thickness, the whole 9 yards disappears. There must be a better way! Thanks!
