## Interpoint Dot Footprint Proximity

USD 9.00 per job.

Register opposite-side dot centers with an explicit sheet mirror and translation, then report every front/back circular-footprint clearance. At most 24 dots per side. This reviews planar proximity; it does not translate Braille or model paper thickness, embossing deformation or readability. Supplied measurements and explicit assumptions only. Use consistent units. No physical inspection, accessibility or structural certification, clinical conclusion, machinery control or external-system change is included. Comparisons use the same twelve significant digits as the report. Integral report quantities must remain exactly representable; unsupported calculation profiles reject before checkout. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.

## Stage Scan Tile Coverage

USD 9.00 per job.

## Model Tab and Slot Kerf Review

USD 9.00 per job.

Review rectangular model tab/slot mating dimensions after centerline kerf and explicit path offsets, including a quarter-turn tab orientation. Positive path offsets enlarge the respective rectangle. Finished tab dimensions subtract one kerf; slot dimensions add one kerf. At most 128 joints. This predicts planar rectangular fit only; corner radii, grain, material deformation, thickness and machine settings require separate review. Supplied measurements and explicit assumptions only. Use consistent units. No physical inspection, accessibility or structural certification, clinical conclusion, machinery control or external-system change is included. Comparisons use the same twelve significant digits as the report. Integral report quantities must remain exactly representable; unsupported calculation profiles reject before checkout.
