Tolerances allows, in a first phase, to apply tolerances to groups of dimensions, either while inserting a tolerance SOLIDWORKS, that is to say starting from tables of tolerances.
Tolerances also allows to rock the dimensions in maximum, mini or average value and to rebuild the model or to create derived configurations. The user always has the possibility of returning to the initial values.
