Figured out the issue:
- It's the drawings that had been created using the pre-windchill drawing format that used &proi_revision to call in the PDM revision.
- Other part was on the computer doing the Windchill publishing, the line "dm_emulate_ilink_sys_parameters yes" was missng from the config.pro. This is in the master config.pro copied to the client installs at startups, so it works fine on the CAD operator PCs. Once this option was added to the config.pro in the PC doing the publishing everything is fine.
