Using layers and turning them on or off in various layer combinations to get the view you want is probably the best way.
You can filter elements so they don't show in 3D but you can't control this in various views and it affects all of the elements.
You might be able to use this for your zones if you never want to see them in 3D but you wouldn't use it for your wall because ALL walls will disappear.
