PDF UNDERLAYS VERSUS DWG XREF ATTACHMENTS
XREFs can cause headaches regarding different Issues: Attachments Vs. Overlays, Demand Load Settings, corrupted files (Recovery demanding), CAD Standard Issues (mainly Layering Properly), Library Structure (Were files eTransmitted and how – or arrived as an Email Attachment – with or without Fonts and data extraction, images, etc.)
On the other hand, PDF Underlays can exclusively contain the data that interests you: in a short session, the drawings of your interest can be elaborated to suit your needs.

I’ve been looking at the most popular Tech-Support Issues at our business. Many approach us on XREF issues, then there are Problematic File Issues and those are catching a big deal of time to our support guys. People are not aware of the fact, the newer the Version the more Sensitive it gets. In forums, I can see many people are getting PICKADD, PICKFIRST issues most as a result of using malpractice old lisp routines, I daily open dozens of files with thousands of RegApps, dozens of excessive Annotation Scales, etc. If you have a good CAD Standard, using the PDF Underlay as an alternative to XREFs, might contribute to you data flow, think about it…
