I tried looking for a answer to my problem, but I can’t seem to find anything to help my situation.
While editing a group in wireframe facestyle, I hid one side of a corridor to have better access to the other side of the corridor. ( Form my searches I realise that there are better ways to do this)
I want to unhide that hidden side of the corridor, but I can’t seem to unhide it. Unhiding all does not seem to work and I have other groups with the exact corridor, so showing hidden geometry is also not helping.
