Hello!
I am having trouble with my Sketchup.
some words appear to not be legible. I have tried changing the display settings but I had not luck.
does anyone have any advice?
I have a deadline and this suddenly happened.
Restart sketchup
I have tried that and hasn’t worked 
If this is on Windows (your forum profile doesn’t say, and I can’t tell from a quick glance at the screen capture), what value do you have the Windows scaling feature set? From memory I think 150% is the suggested maximum.
