Interactive demonstrator
Follow the line.
Submit a ring, inspect live production tickets, and watch the geometry and state move through the same event-driven system.

Send a ring into production.
Choose a few parameters. The service generates the geometry and publishes the job.
What this explores
Digital twins become useful when the interface explains the system.
The prototype treats geometry, production events, and operator feedback as one continuous product problem—not separate technical demonstrations. Updates arrive without moving the ticket under the user's cursor, while the viewer follows the latest part until a specific job is selected for inspection.
