What to expect from an ideal product

  1. Uses ElectricSQL and TanStack DB to sync design changes instantly between all team members working on the same CAD model
  2. Stores design history and parameters in Postgres database so teams can track every modification and roll back to previous versions when needed
  3. Implements CRDT technology to handle conflicts when multiple designers edit the same parts simultaneously without losing anyone's work
  4. Leverages OpenCascade.js for browser-based 3D modeling that works across different devices without installing heavy desktop software
  5. Provides durable data streams that maintain design integrity and keep all collaborators updated even during network interruptions or offline periods
