Parallelism controls parallelism between two lines, surfaces or axis.
In another words, it describes a parallel orientation of one referenced feature to a datum surface or line in 3d tolerance zone.
Parallelism does not controls the angle of the refere ...
Variations on dimensions without tolerances values are according to ISO 2768 for linear and angular dimensions. ISO 2768 is used to define the general tolerance on sheet-metal and plastic parts. For sheet-metal parts ISO 2768-m and for plastic parts ISO 2 ...
