Hello everyone.
The pdf export is incorrect. The dimensions of the Rhino 7 pdf exports are smaller than those of the pdf exports in Rhino 6. The dimensions of the pdf exports in rhino 6 are definitely correct. Testet with the same A3 file in Rhino 6 and Rhino 7. The same with the A0 format. Other DIN formats certainly also affected, but not tested. Please make sure to fix the issue. See the scale in Affinity Design.
Best regards.
