@DesignDude there isn't a way around that. The text is sized by font size while the rest is by paper space. I would suggest editing the scrapbook and resize the symbols you need to suit the typical scale of your work. Save the changes and then you won't have to do it every time you need to use them. Take advantage of the editing time to remove symbols you'd never use and maybe rearrange them to make them easier for you to access.
Hi everyone. Thanks all for sharing your ideas and solution. 👍
I just discovered that 2024 is now versionless! Good, thanks Sketchup developers.
I guess this will apply to older versions after 2021.
I only tested with 2023 and it can open without issues. I dont have legacy programs anymore so I cannot comment about it. http://help.sketchup.com/en/release-notes/sketchup-desktop-20240
This is a known issue and the developers are aware of it and working on a solution. Hopefully they'll get it fixed in time for the first maintenance release.
