It's the classic, "If I paid to create the data (in Creo), and I paid again to store the data (in Windchill), why do I have to pay again to view the data? Software companies are in the business of making money, and they are going to do that any way they can. A couple of options:
1.) Store copies of the data (like PDFs) outside of Windchill. Dump them to a shared network drive or someplace else that can be accessed by anyone without needing a Windchill license. It is possible with a small add-on (or your own customization) to get Windchill to automatically export these files every time something is created or updated.
2.) Get a block of 'Active Daily User' licenses for Windchill. Each of these licenses will allow a 'view-only' type user to access Windchill for a 24 hour period. At midnight the license becomes available again for someone else to use. If you have a large group of very infrequent users, a small number of these licenses can work very well. (We have 10 of them covering roughly 200 occasional users and they are almost never all in use at the same time.)
