WHAT THIS SCREEN ANSWERS

Assembly clearance is a functional result of limits, not an isolated nominal dimension. The page compares opening and mating-feature limits to reveal minimum and maximum possible clearance. A preliminary result should make later review faster, not disappear.

Datums, form, position, surface, coating, temperature, compliance, and assembly path can alter what clears in practice. Confirm functional requirement, complete GD&T, assembly sequence, materials, coatings, temperatures, and inspection plan. That limitation can move the governing case.

Assembly clearance is a functional result of limits, not an isolated nominal dimension. Datums, form, position, surface, coating, temperature, compliance, and assembly path can alter what clears in practice. A recalculation is meaningful only when the changed assumption is visible.

The page compares opening and mating-feature limits to reveal minimum and maximum possible clearance. Confirm functional requirement, complete GD&T, assembly sequence, materials, coatings, temperatures, and inspection plan. The decision remains specific to this application because assembly clearance is a functional result of limits, not an isolated nominal dimension.
