Some drawings ask for a part to be flat in the restrained condition. This is not true flatness but the surface is intended to be flat enough to be bolted or clamped in a flat condition. Normally, if a flatness of 0.003″/ft is quoted, then multiply the diagonal dimension of the part in feet by 0.003″ to get the total flatness tolerance.

Flatness - Engineering Essentials

Flatness ControlPerfect flatness is when all points of a surface lie in the same plane. Flatness is a form control. The flatness control (c) defines how much a surface on a real part may vary from the ideal flat plane. Tolerance ZoneThe flatness tolerance zone is the volume between two parallel planes.

FlatnessFlatness is a condition of a specified surface having all elements in one plane. Flatness tolerance provides a tolerance zone of specified and defined by two parallel planes in where the specified surface must lie. Flatness is applied to an individual surface, flatness tolerance does not need to be related to a datum.
