Solvespace 2.3 (running on macOS and using Arial.ttf)

I am trying to laser cut a nametag made in Solvespace and am running into a few issues. The biggest is that AutoCAD apparently won't open the file (I'm looking for more information as to why from our laser cutting person).

If I open the DXF in LibreCAD (2.1.3 - it's old) it comes in fine. If I then do nothing more than save it then the resulting file is AutoCAD-friendly. I believe that someone else reported this on the forum.

I will continue to investigate the AutoCAD error messages.
