Hi all,

I'm very new to autocad (using autocad mac 2023), having some trouble scaling - I think the trouble is probably with my units (mm) somewhere but I can't figure out where. I am drawing floor plans at 1:1 in model space for a 10m x 8m space, trying to scale at 1:50 to fit on 11"x17" sheet. I can see them on the sheet in the viewport layout at a default custom scale which is 0.000502, obviously they disappear at 1:50.

Not sure what I'm doing wrong here - my units look right but I suspect they are not. Attaching file here! Thanks for your help!
