What import_step_report returns: the bodies, how gracefully the file imported, and the import’s diagnostics.

Fields

solids: Vec<BrepSolid>

One solid per body that reconstructed, in file order.

failed: usize

Things that did not come in (skipped, not fatal): a body that failed to reconstruct, an occurrence whose transform failed, or a mapping that was refused (mapped::StepMappedItemError).

first_error: Option<String>

The first such failure’s text, when failed > 0.

refused: Vec<KernelRefusal>

The bodies the shell-closure gate refused, typed (RefusalClass::UnsoundResult { defect: SoundnessDefect::VectorArea }), in file order. Each is counted in failed. import_step and the feature lane refuse the whole file on any of these; this lane returns the bodies that did import beside them.

failed_refusals: Vec<KernelRefusal>

The bodies that FAILED to build with a typed cause that is not the closure gate’s, in file order: the pinched-vertex split, a BREP_WITH_VOIDS certification, the post-build validation (2026-10-03). Each is counted in failed, and the first is first_error’s text; none refuses the whole file on any lane, which is the outcome their text had.

sheets_skipped: usize

Open surface-model sheets skipped (not solids, so not in failed); also the counter SHEETS_SKIPPED in diagnostics.

approximations: Vec<(usize, Approximation)>

(index into solids, approximation) for every imported body whose shell closes over its bar (import.shell_closure); see ImportedStep::approximations.

stated_precisions_mm: Vec<f64>

Every precision the file states, in millimetres, ascending — see parse::stated_precisions_mm. Empty when it states none.

diagnostics: KernelDiagnostics

The import’s diagnostics: measurements always, plus one import.stated_precision_inconsistent warning when the file’s stated precision is far under the deviation its own geometry shows (precision::stated_precision_diagnostics). Informational only — acceptance never depends on it.
