I have a situation with a roof plan view and the underlay of the level below. Previously I had Hidden certain categories - walls and windows.
Now when I am in the same roof plan view and use this same level for an underlay, the categories that were previously hidden are still hidden - the walls and windows.
I am stumped (no great feet there ...). How can I Unhide these categories within the underlay, in this Roof Plan view?
