I’ve read some of the complaints about the font shrinking to unread-ably small when printing from SU 2020 and suggestions to increase the font size, which makes working on the model awkward, or bringing the model into Layout to print, which works but wastes time when you just need a quick print. To me, it seems like a flaw in the 2020 version. Any solutions other then the two mentioned?
Have you tried changing your font size from points to mm? This should keep the text the same size relative to your model.
