Reference layer syncing

Reference layer syncing ensures external datasets like structural models or site surveys remain physically and temporally consistent as your 4D scene evolves. By anchoring layers to shared coordinate systems—such as EPSG:4326 for geographic or local survey datums—you prevent misalignment during animation or interaction. Engineering tolerances are respected, so minor variations in time-aligned layers don’t trigger false conflicts.

You can toggle visibility of layers per time slice, so a buried utility map appears only during excavation phases, while structural framing shows during erection. The system validates datum alignment automatically, comparing imported files against a project origin defined at project setup. This avoids costly misreads during construction coordination, where A significant shift in a GIS footprint could delay permitting or safety reviews.

Syncing supports live links to external sources Via standard formats—updates propagate when source files change. This is critical when working with evolving BIM models or municipal GIS updates. When a city updates its stormwater infrastructure data, your 4D flood simulation layer updates automatically, keeping narratives grounded in the latest field conditions.
