doc: world_state, world_state_reusing, state_in_frame_at, state_in_frame, face_point_state,
face_point_names and construction_state return Result. A body that could not be placed, a
frame that could not be inverted, a sketch plane or thread axis that did not survive the
placement, or a failed placing worker used to leave things where they were without a word;
now the call fails with what could not be placed. is_placement is the one test of an
occurrence's placement (finite, a rotation that does not mirror, a translation within
1e9 mm). Opening a design names every occurrence that fails it; add_occurrence refuses
one; a joint solution that would place an occurrence outside one is not applied and the
joints placing it report it.
engine: Session::world_state returns Result and keeps a failure in its cache as it keeps a
placed model. bounds, home_camera, open_sketch_plane, the scene builders, the world
previews, frames::to_local and auto_operation pass the error on; helpers answering "not
found" take the placed model from their caller. Commands setting a placement check it
(valid_position, exploded view, fastener at a point, STEP insert matrix).
ui: panels, picks and hovers read the session's placed model through
open_meshing::session_world; a model that cannot be placed shows no placed bodies, and the
viewport says why across its bottom. Pictures and the control channel report the error.
cli, mcp: snapshots, renders, benches and the oracle report the error; the kernel-case rig
records it as the case's failure. Tests read the new Results with unwrap.
