The paper describes a method for the generation of tolerance specifications from product
data. The problem is nontrivial due to the increasing adoption of geometric dimensioning
criteria, which call for the use of many types of geometric tolerances to completely and
unambiguously represent the design intent and the many constraints deriving from
manufacturing, assembly and inspection processes. All these issues have to be modeled
and explicitly provided to a generative specification procedure, which may thus need a large …
