# Circle and rectangle packing
# Scope: Axis-aligned rectangular grid packing; no rotation.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

trayLength = 300 mm
trayWidth = 200 mm
itemLength = 40 mm
itemWidth = 30 mm
gap = 5 mm

columns := floor((trayLength+gap)/(itemLength+gap))
rows := floor((trayWidth+gap)/(itemWidth+gap))
count := columns*rows

check packing target: count >= 20

scenario alternative: trayLength = 240 mm
