Okay, I'm pretty new to this stuff, can someone please explain what I am doing wrong...
I added 8 floors to my project, individually with Create New Floor button.
After closing and reopening the project, all the Elevations had changed by a factor of 100?
I tried recreating them. Same issue.
I tried modifying the existing ones. No Dice...
Am I going mad, or is there some logic I have missed entirely...
