Public reference tests: analytic and FreeCAD expected values (#310)
The oracle no longer uses Fusion measurements. tests/oracle/<case>/ now holds the 76 recipes (our own format, with recorded measurements and tool-specific fields removed) and an expected.json per case: - 55 analytic cases: closed-form values from tools/oracle-analytic/ (stdlib Python, formulas in each case's "method"). - 21 FreeCAD cases: the same recipe built with FreeCAD's public scripting API by tools/freecad-oracle/ (an external program, not a dependency), with a reference.stl for 20. solvecraft-cli oracle compares body count, volume, area, centre of mass, bbox, face counts where the geometry fixes them, and, against reference.stl, the sampled Hausdorff distance and the principal moments (spatial.rs from #301). cargo xtask oracle reads tests/oracle, writes docs/oracle.md with the source of each value, and supports known_failure marks for tracked bugs. CI runs it on every PR; a manual workflow regenerates the FreeCAD values. step-corpus, seam normalisation and the through-all emulation, which only existed to compare with Fusion, are removed. 75/76 pass; 75-sm-bracket-holes is a known failure (#296).

# IGES import (Fusion corpus)
|
||||
|
||||
Generated by `cargo xtask step-corpus --iges`. Each case is a reference part exported from Fusion as IGES 5.3 (kept locally in `plan/fusion/oracle/`, never committed). SolidCraft opens `part.igs` exactly as File → Open does and compares with Fusion's measurements of the part it exported: body count, volume and area (relative tolerance 1e-3) and the number of faces read from the file. How IGES is read: see [STEP import](step-import.md#iges). 50-sweep-tight-bend is written by Fusion as five loose, partly degenerate surfaces (seams running into slits, a ring given twice); Fusion cannot read it back as a solid either.

Generated by `cargo xtask oracle`. Each case is a part built in Fusion (recipe and measurements kept locally in `plan/fusion/oracle/`, not committed). SolidCraft replays the recipe through its command engine and compares body count, volume and area (relative tolerance 1e-3) and face/edge/vertex counts (exact). SolidCraft counts each closed-surface patch once and ignores seam edges and vertices; when body count, volume and area pass but the raw counts differ, Fusion's counts are normalised the same way from its face, edge and vertex lists (faces cut from one cylinder, cone, sphere or torus and separated only by seams count once; an edge on that surface and no other is a seam and is dropped; a vertex left with two edges joins them) and compared exactly; the note gives both sides' raw counts.
|
||||
Generated by `cargo xtask oracle`. Each case in [`tests/oracle/`](../tests/oracle/) is a part described by our own `recipe.json`. SolidCraft replays the recipe through its command engine and compares the result with `expected.json`: body count, volume and area (relative tolerance 1e-3 unless the case states another), centre of mass and bounding box (within 1e-3 of the part's size), face count where the geometry fixes it, and, where the case has a `reference.stl`, the sampled symmetric (Hausdorff) distance between the two surfaces and the principal second moments of both triangulations. Every rebuilt part is also exported as STEP, validated and read back.

- **analytic**: closed-form geometry worked out by hand (prisms, cylinders, cones, spheres, tori and Pappus' theorems, constant-radius fillets on straight edges, sheet-metal bends as annular sectors). The scripts in [`tools/oracle-analytic/`](../tools/oracle-analytic/) compute them and give the formulas.
|
||||
- **freecad <version>**: the same recipe built with FreeCAD's public Python scripting API by [`tools/freecad-oracle/`](../tools/freecad-oracle/), an independent kernel run as an external program. FreeCAD is not a dependency of SolidCraft. Where the two kernels legitimately build a different shape (for example the corner patch where fillets meet), only volume and area are compared, within the tolerance the case states.

Fusion builds these only with its Design Extension, which the oracle account lacks, so there is no Fusion part to compare with. They follow Autodesk's public descriptions of the features and are checked against hand-computed geometry; the plastic rule library values were read from Fusion's API.

|

| 74-sm-unfold-refold | analytic | pass | | U channel 80x50 (t 2.5, R 2.5, base y 5..45, flanges z 5..20) with the flat-pattern slot x 35..45, y -12..10 refolded: BA = (pi/2)(R + K t) = 5.654866776, so the slot removes base y 5..10, the whole y=0 bend and the flange from z 5 to 5 + (12 - (BA - 5)) = 16.345133224; x-segments 0..35 / 35..45 / 45..80 | unfold/refold maps flat distance through the K-factor neutral layer (K 0.44) |
|

A = sum of prism areas - 2 x 4 joint areas (75t, 75t, 35t, 35t) + hole walls - hole discs | step 14 (solid.extrude): invalid input: sew: nonmanifold edge contact; SolidCraft convention: the second flange trims the base under the first bend, so bend 1 stops at x 75 while flange 1's panel runs to x 80 (open corner relief, no fill). |
|
||||
| 76-sm-thickness-variant | analytic | pass | | final rule thickness 3 (bend radius = Thickness = 3): base y 6..60 x 3; bend annulus R 3..6 about (y 6, z 6); flange y 0..3, z 6..20; extrusion along x 100 | the rule's thickness edits regenerate the whole sheet body; only the final 3 mm state matters |

## IGES
|
||||
|
||||
IGES 5.3 files (`.igs`/`.iges`) open, insert and drop the same way: `crates/kernel/src/iges_in.rs` (written from the published specification) restates the file as STEP and the STEP reader reads it, so the feature holds STEP text. Read: manifold solid B-reps (186) with their shells, faces, loops, edge and vertex lists; trimmed (144) and bounded (143) surfaces, and bare B-spline patches, sewn into a solid by their shared edges (an open body when they do not close); lines, circular arcs, ellipses, composite curves, rational B-spline curves; planes (108, 190), cylinders, cones, spheres, tori, rational B-spline surfaces, surfaces of revolution and tabulated cylinders; transformation matrices; units; colours (314 and the predefined numbers); body names (name properties, else labels). Not read yet: ruled and offset surfaces, curves on surfaces given only in parameter space. Export (`file.export` to `.igs`) writes each body as a manifold solid B-rep on the same surfaces a STEP export uses, with its name and colour.
|
||||
|
||||
## 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). SolidCraft 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.
