Thank you, Solver
"Edit Area" only allows me to copy and paste one floor at a time. It might just be a built-in limitation of my consumer-level software. There is no sub-menu after selecting Edit Area. No option to select all floors.
I've spent the last few hours copying and pasting one floor at a time. Maddening trying to align each floor. I would love it if I could create a couple of reference lines and duplicate their exact position on each floor. Then, I suspect my solution is mastering the snap settings.
