docs/formats/tagged-mesh.md defines the exchange: 3MF Core with an optional ft:face attribute per triangle (and ft:faces per object) in a ModelCraft namespace. modelcraft_geometry::tagged_mesh::read_3mf reads it from bytes (wasm), capping every size and count and range-checking every index and coordinate. geometry.import.mesh adds the surfaces to the session, which keeps them beside the open design and restores them when a command fails.
