Form Tolerances and Positional Tolerances

3-D Dimensioning + Text > Symbols > Form/Pos

Form tolerances and positional tolerances are used to ensure the functioning and exchangeability of workpieces and assemblies. Form tolerances limit the permissible deviation of an element from its geometrically ideal dimension. Positional tolerances are direction, location and run-out tolerances. They limit the permissible deviations of two or more elements from the ideal position in relation to one another.

The geometrical tolerances are specified in a rectangular frame - the tolerance frame. It consists of two or more compartments containing the symbol for the feature to be toleranced, the tolerance value, the letter for datums.

The tolerance specification can either be aligned horizontally or vertically.
