Working on the second level of my first project and when I double click the second floor, the first floor is already in the view, and it seems to be active, meaning if I deleate a wall for instance it deleates it in the first floor plan. I went to Properties to see if it the underlay was turned on and it wasnt. I turned it on and there was a preseptible change, the first floor plan appeared. I've looked to see if something was not checked in the properties box and even lookes at View in the ribbom, I must be missing something? Can anyone help, it's lonely out here!
Sounds like you might want to check the view range of the 2nd floor plan. You might want to chack to see if the view range is extending down into the 1st level for some reason.
In addition to View Range (Cut Plane nad View Depth) you should also check the walls' height.
Whether they are stopping at level 2 or going beyond that.
