… hi @Anonymous
… take a look at this video:

…. Or add an elevation to the floor plan (to the project)
… in view tab
… open elevation and paste it on the screen
… there you have your elevation
… (you can rename it)

… but I would not recommend that
…. It is better to start with a default
… and modify it
… you will be running into way less issues / problems
