Its main weakness resides in its non-applicability to dimensioning and tolerancing at the preliminary project stage (conceptual design) of a mechanical system. The possibility of specifying the parameters of a mechanical part in 23

Clé , ment a non-nominal state by indicating a variation interval for certain of these parameters (parametric tolerancing) is not totally ruled out. On the other hand, it is impossible to obtain an instance of this part in its final state subsequent to parametric differentiation. Due to this inadequacy, justified mistrust has arisen from an industrial standpoint regarding the use of 3D dimension chains resulting from a parametric differential. Hence the current desire by manufacturers to make sure of the existence of the final object for any combination of tolerances. The explicit values of the dimension...
