Automatic generation of dimension and tolerance information for fastened components

摘要

A common task when designing computer-aided design (CAD) assemblies is to ensure that the tolerances applied to each component are such that the assembly will function as expected when the parts are made to the extremes of their tolerance zones. The disclosed methods and systems automatically generate dimension and tolerance information for fastened components. Given a source component with dimensions and tolerances, the dimensions and tolerances are automatically applied to mating entities of a target component such that fit is insured without interference when the parts are manufactured at worst case, or at the extremes of their tolerance zones.
