The 3D asset mapping API lets you create and manage links between 3D model nodes and CDF assets. This connection enables you to navigate from a 3D visualization to the corresponding asset data (time series, events, files) and vice versa.

​
Why map nodes to assets?

Mapping 3D nodes to assets lets you:
  • Navigate from 3D to data — Click a node in a 3D view to see its associated time series, events, or files
  • Navigate from data to 3D — Start from an asset and locate its representation in one or more 3D models
  • Enrich visualizations — Display live asset data alongside 3D geometry

​
Key operations

You can create mappings, update them, and query them in several ways:
  • Filter by bounding box — Find nodes within a spatial region
  • Find mappings for an asset — Retrieve all 3D mappings for a given asset across models
Asset mappings are per-model and per-revision. When you update a revision, you may need to recreate or verify mappings.
