I’m totally convinced Adobe software has “Random Screw Up” in its software.
Just had a random error creep in somewhere that prevented a PDF from forming. Just got the little texty thing that said I wasn’t saving with PDF compatibility turned on. Uh, it was.
Then tried to copy paste to new doc but doing so would “cause some elements to fall off the artboard” No idea what parts those might have been. The selection box was less than the page size.
Then tried to half scale it as it was 199.8" and PDFs have to be under 200" (maybe it was too close?) Nope.
Each time I would get a PDF view in Illustrator but if you actually opened the saved PDF file in Acrobat you got the little text box instead of art.
Of course the solution was to totally restart Illustrator, and re-open the file and try the save-as again.
I think I’m moving that option up to #1 on my ARSU troubleshooting list.
Thankfully I didn’t lose the art.
