I use Rhino for a lot of design and I’m sure there’s other people using CAD.
It seems like there would be a lot of people that would benefit if Glowforge would read DXF files. It’s a pretty open standard.
Yes, Rhino will save in Illustrator (AI) format, but it doesn’t work that well with Glowforge. (There’s sizing and positioning issues so I have to push it through Illustrator itself, first.)
