I use Autoddesk Revit for creating architectural plans as PDFs, and have been getting strange issues when I add a watermark in PDF Architect (5, I believe). The PDFs are fine when I first print from Revit, but when I open up the combined PDF file to add the watermark and save, the title block (border) disappears and the watermark does not show. Before yesterday I have been getting an issue where the title block will disappear on 2 sheets that I move up to be at the beginning of the combined file.
Anyone have any idea? This is very strange.
