Physical AI Lab Three foot projections stayed over the usable top, while a separate 4 × 4 mm reference footprint overlapped an excluded region. Full relative-pose correction restored coverage in our Blender model.
A 12 mm X sample cleared both parallel keys. With perpendicular keys, each prescribed X or Z trial cleared one interface while intersecting a wall at the other.
A bowed member kept approximately 480 mm² of projected face overlap but failed three-interface closure. Actual Blender measurements separated pose adjustment from shape mismatch.
Moving one complete ring reduced the shared opening from 640 to 480, 240 and 0 mm² while the plate gap stayed at 2 mm. The actual geometry check separated opening overlap from spacing.
Both heads covered the pane, yet shifted or tilted placements implied different pane poses. A face-derived frame check separated those errors in an actual Blender experiment.
Clear journal openings did not prevent the larger roll from intersecting its neighbors. Changing the receiving spacing resolved that static geometry mismatch.
Deep seating produced finite shelf overlap without interference; the same 60-degree turn at a shallow position made the solids intersect.
Separate left- and right-guide corrections overpredicted the combined upper route by about 0.17 mm in this finite four-state Blender test.
Two cable fans admitted explicit bounded tension certificates, while a one-sided layout excluded the required zero horizontal force.
A noncircular guide added 3.30 mm over one 30-degree interval and 5.31 mm over the next, so one fixed conversion missed the second sample.
