What the AI judge checked

Pass:The overall form matches the reference: the same kind of object, the same silhouette from the matching angle
- Opus 4.8: pass: The rendered part is an L-bracket with a vertical flange and horizontal base identical in silhouette to the reference.
- GPT-5.6 Sol: pass: The renders show the same right-angle L-bracket silhouette and overall form as the reference.
Pass:Proportions match: the relative sizes of the major dimensions agree with the reference within what the eye can judge
- Opus 4.8: pass: The relative lengths of the base and height of the flange, plus thickness, match the reference closely.
- GPT-5.6 Sol: pass: The base length, bracket width, upright height, and plate thickness visually agree with the reference.
Pass:Every major feature visible in the reference (holes, slots, bosses, tabs, lips) is present in the result
- Opus 4.8: pass: Two elongated slots and two round holes are present just as in the reference.
- GPT-5.6 Sol: pass: The produced part includes both elongated slots and both circular holes visible in the reference.
Pass:Those features sit where the reference has them
- Opus 4.8: pass: The slots sit toward the center-left and the two round holes toward the far end, matching the reference layout.
- GPT-5.6 Sol: pass: The slots and circular holes occupy the same paired rows and longitudinal regions as in the reference.
Pass:Nothing is present that the reference does not show — no decorative or unexplained geometry
- Opus 4.8: pass: No extra decorative or unexplained geometry appears beyond the slots and holes.
- GPT-5.6 Sol: pass: No additional bosses, cutouts, fillets, tabs, or decorative geometry are visible.
Pass:Edges are straight and faces are flat — a CAD rebuild, not a copy of the mesh's facets
- Opus 4.8: pass: Edges are straight and faces flat with no visible mesh faceting, indicating a proper CAD rebuild.
- GPT-5.6 Sol: pass: The plates have flat faces and crisp straight edges consistent with a clean CAD reconstruction.
Pass:The slots are elongated openings, not round holes
- Opus 4.8: pass: The two slots are clearly elongated rounded openings, distinct from the two round holes.
- GPT-5.6 Sol: pass: Both slot features are clearly elongated openings with straight sides and rounded ends.

One reviewer

Verdict: acceptable (from the ranking's acceptable line, not typed on this attempt)

Measured

✓ watertight: true == true
✓ one sub-part named bracket: ok
✓ volume within 3 % of the mesh: ok
✓ bounding box within 0.5 mm of the mesh: ok
✓ symmetric difference under the measured floor: ok
✓ holes match the mesh: ok
✓ the imported bracket is still declared as an import: ok
✓ asked the oracle at most once: ok
✓ sweep thickness=2: base thickness tracks the control: ok
✓ sweep thickness=2: the upright still reaches the mesh's height: ok
✓ sweep thickness=8: base thickness tracks the control: ok
✓ sweep thickness=8: the upright still reaches the mesh's height: ok
✓ sweep holeDiameter=3: hole diameter tracks the control: ok
✓ sweep holeDiameter=8: hole diameter tracks the control: ok
✓ sweep width=30: width tracks the control: ok
✓ sweep width=50: width tracks the control: ok
