Dimensional tolerances are selected by the designer or purchaser to make sure that the part can perform its function reliably and fit into its designed location. Assigning dimensions to a part requires identifying the desired feature size. Tolerances communicate how much variation from the desired size can be tolerated.(plate) December 7, 2016 A Means of Dimensioning and (steel) location (and sometimes the size of) tolerance zones within which variations are allowed.

Form Tolerance - A form tolerance states how far an actual surface is permitted to vary from desired geometric form. Expressions of these tolerances refer to limits of size, flatness, straightness, parallelism, perpendicularly, angularity, roundness, cylindricity, profile of a surface and profile of a line.(plate) GD&T, Geometric Dimensioning and Tolerancing,GD&T 5 dimensions tolerances and surface(steel) The flatness tolerance may be used to control the form of derived median plane.
