Set up and use standard Windchill visualization services.
Shop floor (and everyone else) access Windchill data presented in Creo View (ProductView prior to Windchill 10.x).
It's core to Windchill to publish and handle Pro/E and Creo. Can set up for SolidWorks or other CAD. Additional cost and module to publish MS Word but can be done.
Optionally set up watermarking such that every Drawing / Document viewed in Creo View andn optionally printed / saved off to PDF includes identification of the exact WIndchill page, and optionally user, date, etc..
Don't know of a way to utilize bar codes but that may be something that could be developed as the input for what to search for. Meanwhile, operators would just search for the needed document / drawing Number.
