Thanks so much for the reply - turns out I'm just a complete moron, and was entering my measurements in feet when they should have been inches....sigh.

Hi, major beginner here, I added a bathtub to my floor plan, it says its 5' wide, but it shows up as about 3 inches wide on my floor plan. Can someone tell me what I did wrong or how to fix it? My apologies in advance if it is something very obvious, I just can't seem to figure it out. Thanks!
