Instant 3D Updates

Every cell change triggers immediate recalculation and 3D model regeneration. Watch your parametric designs update in real-time as you modify values, with changes reflected in under 16 milliseconds.

  • Sub-16ms recalculation time
  • Optimized dependency graph
  • Incremental updates (only changed cells)
  • No manual refresh needed
  • Smooth 60 FPS visualization
