We have settled on never ever ever leaving the top constraint for walls to be “unconnected”. Even if they are short, like partitions for cubicles or something, we still connect them to the level they are on and then offset them to the proper height. Why would I be such a wall top constraint fascist?
Isn’t it always that way?
Seriously, they need the tops of the walls to be constrained to something. For most of the walls. So, it’s just plain good habit to get into to always pay attention to the tops of the walls. Or the top of everything for that matter. Remember, this isn’t CADD anymore.
