Measure.Length.Form.Flatness

MeasureDimensional

The minimum normal (perpendicular) distance between two parallel planes that fully contain a surface. Commonly, the two parallel planes may be constructed from the surface itself (in which the highest point and lowest point of the surface would be tangent to the two parallel planes), but a drawing may specify how the parallel planes should be constructed.
