When the Visualization server initiates a client request to convert Creo Elements/Direct Modeling data to the Creo View format, the server uses the ccmodelworker to convert the CAD data in a background session of Creo Elements/Direct Modeling. This Visualization server could be a Windchill server or another customized server environment.

The Creo Elements/Direct Modeling worker is an important link in achieving the full functionality of the Visualization server. For more information, refer to Visualization Server Definition.
