Setting VP scale to 1:50

Hello, quick question for the layout masters from a newbie to layout. Using sketchup pro 21 on a 2017 Imac27. Is there any logical reason why I can’t set viewport scales to 1:50? I can set every other scale that I use, i.e. 1:20 1:100 1:200 etc… but if I set 1:50 it just changes to 1:100

Thanks for your time!

Share the LO file so we can see what you’ve got going on.


make sure “preserve scale on resize” is checked

Preserve Scale on Resize will automatically be checked when a scale is selected. The state of that tick box won’t affect whether or not a scale can be selected.

Thanks guys! It just seems to be a glitch in the program. If I click on a random imperial scale I never use, then back on 1:50 it works. If I change from 1:100 to 1:50 it doesn’t. I’ve only started trying out layout after using autocad since forever, a few odd things like this catch me on occasion… that, and trying to convince my engineer that files from sketchup are ok!
