Spatial Interchange

Use plan_conversion before a cross-DCC import or export when source and target coordinate conventions are known. The tool returns a pure conversion plan; the importing or exporting adapter remains responsible for applying it to scene data.

Do not infer a convention from a DCC name alone. Query the live scene, import settings, or file metadata first: Maya up-axis and units are scene settings, Blender FBX axes are operator settings, and USD stages carry upAxis and metersPerUnit metadata.

The 3D Transform Visualizer is a useful educational model for signed right/up/forward bases. It is not a file converter or a source of truth for a live scene.
