Is there a tool to manage the deployment of DraftsSight Enterprise to multiple users?

Yes. The DraftSight Deployment Wizard provides this functionality. The tool is provided by the DraftSight Technical Support team. DraftSight Enterprise and DraftSight Mechanical customers should contact the partner from whom they purchased DraftSight who will raise a Service Request on their behalf. Customers who have purchased directly from Dassault Systèmes should use the webform or 3DSupport App to create a service request: https://www.3ds.com/support/discover-3dsupport-app/

The guide for using this tool is available from the DraftSight website in documentation section: https://www.draftsight.com/media/deployment-tool
