swworker Overview
The SolidWorks worker is used to manage the relationship between SolidWorks and the Visualization server. swworker opens a non-graphical session of SolidWorks, and converts the CAD data to the Creo View format used by the Creo View client.
To configure the worker, you must know the Visualization server host name, the port number that the Worker Agent is listening on, and the complete path to the worker script swworker.

Only one instance of SolidWorks can be run on a computer. If you are already running SolidWorks, swpublish, swbatch, or swworker, any attempt to run another swworker process will fail, displaying the following error:
sw2pv Fatal: SolidWorks is already running please exit SolidWorks first
