| # CAD Synthesis Benchmark — test_bench |
| |
| Small-scale benchmark for **image → CadQuery code** generation. |
| |
| **Task**: Given rendered views of an industrial part, generate CadQuery code that reproduces it. |
| |
| **Evaluation**: Execute code → export STEP → compute IoU vs GT STEP. |
| |
| ## Splits |
| |
| | Split | Families | Description | |
| |-------|----------|-------------| |
| | `test-iid` | 54 train families, XY plane | In-distribution test | |
| | `test-ood-family` | 19 held-out families | Family generalization | |
| | `test-ood-plane` | 54 train families, XZ/YZ | View generalization | |
| |
| OOD families: `bellows`, `worm_screw`, `torus_link`, `impeller`, `propeller`, |
| `chair`, `table`, `snap_clip`, `waffle_plate`, `wire_grid`, `mesh_panel`, |
| `t_pipe_fitting`, `pipe_elbow`, `duct_elbow`, `dome_cap`, `capsule`, |
| `coil_spring`, `bucket`, `nozzle` |
|
|
| ## Sample Fields (bench_manifest.jsonl) |
| |
| ```json |
| { |
| "stem": "synth_handwheel_000042_s9999", |
| "family": "handwheel", |
| "difficulty": "easy", |
| "base_plane": "XY", |
| "split": "test-iid", |
| "feature_tags": {"has_hole": true, "has_fillet": false, "has_chamfer": false}, |
| "feature_count": 1, |
| "ops_used": ["circle", "extrude", "union", "cut"], |
| "gt_code_path": "data/test-iid/synth_handwheel_000042_s9999/code.py", |
| "gt_step_path": "data/test-iid/synth_handwheel_000042_s9999/gen.step", |
| "composite_png": "data/test-iid/synth_handwheel_000042_s9999/views/composite.png" |
| } |
| ``` |
| |
| ## Metrics |
| |
| - `exec_ok`: code executes (0/1) |
| - `iou`: voxel IoU vs GT STEP |
| - `feature_f1`: F1 of feature_tags (hole/fillet/chamfer/slot) |
| - `detail_score`: `0.4 × iou + 0.6 × feature_f1` (primary ranking metric) |
| |
| ## Generation |
| |
| - Pipeline: `cad_synth` (73 families, parametric, multi-plane) |
| - Seed: 9999 (held out from training seed 1337) |
| - Rendered: 4-view normalized PNGs + 2×2 composite |
