spatial-code v0 (pilot)

Small, fully synthetic text→CAD-code pairs (OpenSCAD and CadQuery) for simple parametric solids: boxes, cylinders, spheres, tubes, plates with 4 holes, cube−sphere differences, cube+cylinder unions, L-brackets.

Construction

• Template generator, random.Random(42); code and prompts (EN + templated JA) generated from the same parameters.
• Every row executed: OpenSCAD 2021.01 CLI → STL, CadQuery 2.8.0 → STL; mesh checked with trimesh (non-empty, finite bounds, watertight, volume>0). Failures excluded (see QUALITY.md).
• Exact-code dedupe. Split by hashed prompt (80/10/10 target; realized 147/13/18 over 178 rows).

Limitations (please read)

• Pilot scale (178 rows, 8 shape families); low diversity, mostly numeric variation. Not a benchmark.
• Prompt↔geometry correctness is by construction, not independently measured.
• CadQuery spheres/cube−sphere were rejected by the watertight check, so dialect coverage is uneven.
• Japanese prompts are template translations, not native-written.
• Small test/hold splits; statistics on them are high-variance.
