I'm not sure if I attached the plan correctly, I exported and attached it. Unless there is another way to post it? MK V3.dwg

I did try to copy the basement stairs (but the basement ceiling height is different) on to the first floor (so the stairs would go from the first to second floor) but all that did was paste stairs on top of the current stairs. I watched that video, but it didn't seem to help. I currently have L stairs from basement to floor 1. Trying to mirror those starts from floor 2 to 3 however the ceiling height is 1ft different.

I've created L stairs from the basement to the main floor. I cannot figure out how to carry those floors to the next floor.
