Bounding box

rulingA decision by Aristide or Jordan. True because it was decided; it can be superseded, but it cannot be stale.

Bounding box = the smallest upright (axis-aligned) rectangle that fully encloses a part — its width × height on the sheet. Cheap to compute, so it is a useful first-pass estimate for sizes, envelope checks and rough layout.

What it is NOT for

Ruling (Jordan, 2026-08-26): “For nesting, gaps will be between actual part geometry, not the bounding box.” The ruled part-to-part gap (the Rev2 min-gap column) is the closest approach of the parts’ true outlines. A part that doesn’t fill its rectangle — like the BNM78651 V-strip — leaves huge dead space if boxes are spaced instead of outlines.

Where it came from

• Build 139 nested that strip on a bounding-box grid: 0.2" between the boxes, far more than 0.2" between the parts — Jordan flagged it (“There is way more space than that between parts”). 21 blanks per sheet.
• Build 140 meshed rows to true-outline contact at the ruled 0.2": row pitch 6.206" → 4.031", 32 blanks on the same sheet.

Consequences: every nester slides parts to true-outline clearance, and every nest audit measures the min gap on densely sampled real geometry — a bounding-box spacing check can only ever be a fast pre-filter, never the gate.
