I have a stacked wall (stucco base, glass plate and metal cap). In the attached image, the wall is justified so that its exterior finish surface aligns with the edge of the decks. In some places it "joins" and the separating line disappears, in other areas...NOT!
I've tried several ways to deal with it and am getting nowhere. I could cheat and have the base of the walls go all the way down to the bottom elevation of the decks and then pull the decks in...but I just want to know why it joins in one instance and not another.
Thanks
