proeworker Server Controlled Publishing
When the Visualization server initiates a request to convert Creo data to the Creo View format, the server uses proeworker to convert the CAD data in a background session of Creo. This Visualization server could be a Windchill server or another customized server environment.
The Creo worker is an important link in achieving the full functionality of the Visualization server. For more information, refer to Visualization Server Definition.
