Computer application to aid the unidirectional functional dimensioning and tolerancing synthesis

The task of defining the parts in mechanical assembly based on their functional purpose is done by the functional dimensioning and tolerancing which tries to optimise its dimensions and tolerances. This work is very hard and complex to do. The actual development of CAD systems, which allows us to introduce intelligent help, seems to be the indicate tool to do the work easier. The international technical literature offers a number of investigation projects that contribute to establish the bases for implementing this intelligent help, in order to help the functional dimensioning in the design phase. The main aim of this study is to define and programme a computer application to aid the unidirectional dimensioning and tolerancing synthesis using graphic design (CAD).
