I tried resetting the camera position in Layout, restarting layout, and always got the same result.
My workaround was to open the PDF in Illustrator, and insert a screenshot.
It looks like the fix for this won’t come very soon. The workaround is to change the graphics engine to the classic one, then the export comes out looking correct.
You mean here?
Can I model using new graphics, then switch just for the export?
This is a better workaround than I used, which involved swapping images out in the exported PDF…
