I notice though that the walls don't clean up for the level that is not shown in the cut-plan and when you drop windows in they are not visible unless you change the cut plane again. So although it will show correctly in the layout its is the working environment that is the hassle as you need to keep changing the cut-plane as you are working on different parts of the job and can't see everything at once.
What do you mean by symbolic walls?
