Are you able to tell us which Archicad version do you use ?
It seems to be an old version, I think about 19.
Hey there, I am having a similar issue but with entire views on random sheets. The PDFs set looks fine in Mac preview and other PDFs but when I open in Adobe acrobat random views do not show. Unfortunately most people use Adobe acrobat so I need to figure this out. Acrobats message says "an error exists on this page, acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem." Let me know if anyone has any insights.
