- The flatness callout controls the uniformity of a surface or a median plane as needed. It defines two parallel planes on either side of the flat surface as the tolerance zone for the surface. All the points on the specified surface must lie between these two planes for part approval.

Two things to note about flatness for a feature of size (Flatness DMP) compared to surface flatness: Flatness, as applied to a feature of size, automatically overrides Rule #1 of Geometric Dimensioning and Tolerancing.
Feb 17, 2024 · Flatness in GD&T has a 3D tolerance zone that is defined by two parallel surfaces above and below the referenced surface. The entire surface must lie within these two virtual planes for it to conform to the defined quality requirement.

Flatness is a GD&T form tolerance that is conceptually simple. According to the ASME Y14.5 standard , it “specifies a tolerance zone defined by two parallel planes within which the surface must lie.”
GD&T Flatness is a common symbol that references how flat a surface is regardless of any other datum’s or features. It comes in useful if a feature is to be defined on a drawing that needs to be uniformly flat without tightening any other dimensions on the drawing.

Oct 9, 2023 · Jason discusses form controls on a per unit basis using the example of controlling flatness on a large surface in this Question Line Video. We received a question from a student, wanting clarification on a feature control frame calling out flatness.
Flatness is the 3D version of surface straightness – Instead of the tolerance zone between two lines; the tolerance zone exists between two planes. When Used: When you want to constrain the amount of waviness or variation in a surface without tightening the dimensional tolerance of said surface.
