Hello
I have the same problem but not only for PDF, also JPG.
This is my model :
this is what I get when I export to PDF
And this is what I get when I export to JPG
I uninstalled & reinstalled Sketchup 2018 pro. No change.
There was a previous yet closed topic about it, that suggested to tick map windows fonts to pdf base fonts that removes the bbox error but won’t show any accent such as é à è that I need in french.
here : Dimension Font Help!
I recently changed the font in model info, and I have the problem since then. No patch since the problem has been pointed out ?
