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 5.5: pass: The red result shows the same round cylindrical knob with a chamfered top as the reference, with matching silhouettes in iso, side, top and bottom views.
- GPT-6 Sol: pass: The produced part has the same round body and chamfered-top silhouette as the reference.
Pass:Proportions match: the relative sizes of the major dimensions agree with the reference within what the eye can judge
- Opus 5.5: pass: The diameter-to-height ratio, chamfer width and hex size relative to the body match the reference views closely.
- GPT-6 Sol: pass: The body height, diameter, and chamfer width appear to match the reference.
Pass:Every major feature visible in the reference (holes, slots, bosses, tabs, lips) is present in the result
- Opus 5.5: pass: Both the chamfered top edge and the hexagonal underside socket appear in the result.
- GPT-6 Sol: pass: The top chamfer and underside hexagonal socket are both present.
Pass:Those features sit where the reference has them
- Opus 5.5: pass: The hex socket is centered on the bottom face with the same orientation as the reference, and the chamfer is on the top edge.
- GPT-6 Sol: pass: The chamfer surrounds the top edge, and the hexagonal socket is centered underneath as in the reference.
Pass:Nothing is present that the reference does not show — no decorative or unexplained geometry
- Opus 5.5: pass: No extra geometry beyond the body, chamfer and hex socket is visible in any render.
- GPT-6 Sol: pass: The renders show no additional geometry beyond the reference features.
Pass:The top edge is chamfered, not sharp
- Opus 5.5: pass: The side and iso views show an angled band at the top edge, and the top view shows it as a ring around the flat face.
- GPT-6 Sol: pass: A sloped band is clearly visible around the top edge.
Pass:A hexagonal socket is visible in the bottom view
- Opus 5.5: pass: The bottom view clearly shows a centered hexagonal socket.
- GPT-6 Sol: pass: The bottom view clearly shows a hexagonal socket.

Measured

✓ watertight: true == true
✓ one sub-part named knob: 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
✓ the socket clears a 8 mm key across the flats: ok
✓ the socket is hexagonal, not round: ok
✓ the socket is 6 mm deep: ok
✓ the imported knob is still declared as an import: ok
✓ asked the oracle at most once: ok
✓ sweep diameter=10: diameter tracks the control: ok
✓ sweep diameter=60: diameter tracks the control: ok
✓ sweep height=8: height tracks the control: ok
✓ sweep height=40: height tracks the control: ok
