When converting a CAD drawing to PDF and the drawings contain links, accessing in Foxit PDF has the links appearing rotated on the page.
This appears to be a compatibility issue with our Foxit PDF Editor software for AutoCAD versions 2016 and older.
We have seen correct orientation of drawing links when the PDF is exported from AutoCAD Suite 2019 and have determined that the recommended solution is to update from AutoCAD 2016 before testing opening converted PDFs in Foxit PDF Editor.
