Vendored truck-stepio (writer only): an intersection curve's second surface was written at the first one's id (duplicate ids for every boolean edge), and revolved surfaces lost their orientation (the modeling-surface sense was always true; inverted or mirrored revolutions came out inside out). Export now writes intersection edges as C1 cubic B-splines through exact points, so files carry plain 3D curves and no redundant surfaces. Vendored truck-meshalgo: hinted parameter searches that run off a B-spline's domain are rejected or clamped (meshing their grid never finished). STEP import: straight revolution profiles are bounded in the meridian plane and stop at the axis; loops on revolutions start away from the axis; face extents include edge end points. Edges between pieces of one split surface draw as seams. kernel::step_validate checks a STEP file (duplicate ids, dangling references, dense numbering); the oracle replay now exports every rebuilt part, validates it and re-imports it with no warnings and the same volume (all 32 rebuildable cases pass).

STEP import
SolveCraft reads STEP (ISO 10303-21; AP203, AP214 and AP242 geometry) with its own reader in crates/kernel/src/step_in (written from the public standards; no third-party STEP code). A STEP file becomes an Import base feature on the timeline: it holds the file's B-rep (the STEP text is kept in the design, so the design reopens without the file) and later features — fillets, holes, cuts sketched on its faces, shells — build on its bodies.
- Open: File → Open (
doc.open) accepts.step/.stpin any case and starts a new design;solvecraft part.step;solvecraft-cli eval part.step,solvecraft-cli run script.json --in part.step; the MCPopentool. - Insert into the current design: File → Insert STEP… or SOLID → INSERT (
FusionImportCommandFromToolbar {path}). - Drag and drop a STEP file on the window: inserted when the design has features, opened otherwise.
Read: manifold solid breps (with voids), faceted breps, shell-based surface models; planes, cylinders, cones, spheres, tori, B-spline and rational B-spline surfaces (with knots, Bézier, uniform, quasi-uniform), surfaces of revolution and linear extrusion, trimmed surfaces; lines, circles, ellipses, B-spline curves, polylines, trimmed/surface/seam curves; length and angle units (SI prefixes, conversion-based units such as inches); product names (body names come from the solid's name, else the product's); surface colours; assemblies (next-assembly-usage occurrences placed by item-defined transformations, and mapped items) — the product tree is kept in the feature for the components milestone. Files are untrusted: sizes, entity counts and nesting are capped and every kernel call is guarded. What cannot be read becomes a warning on the feature (a face left out gives an open body); not read yet: offset surfaces, pcurve-only edges.
Fusion corpus
Generated by cargo xtask step-corpus. Each case is a part exported from Fusion as STEP (AP214; kept locally in plan/fusion/oracle/, never committed). SolveCraft opens part.step exactly as File → Open does (an Import base feature) and compares with Fusion's own measurements: body count, volume and area (relative tolerance 1e-3) and the number of faces read from the file.
60 / 66 files pass.
