I want to see how others may be adding persistent or non persistent engineers stamps and signatures to SolidWorks drawings (or other documents) via a workflow in EPDM. Are you using custom API or is there an add-in that does this for you? How well does it work? Thoughts? Technically we are top either use a hard stamp and sign/date or an electronic version and overlay a signature and then date our drawings, so ...
I like creating a note on the drawing, linking that note to the file properties, then having the workflow update the file properties via the datacard.
