I want to export drawings to Pdf so that they can be printed on a large format printer. The drawings are custom sized e.g. 5190mm x 2820mm. When I open the exported document using PDF reader. The files are blank. When opened using preview (on a Mac) the file displays correctly. My printers can use the file but myclients can't see anything. Is there a way to fix this?
