A constraint solver to define correctly dimensioned and overdimensioned parts

First, the geometric constraints considered are described, and the use of each one justified, together with the numerical methods used to resolve the set of non-linear constraints obtained. A procedure has also been developed for choosing the set of independent constraints of the system, by introducing the priority factor concept, which lets the overriding constraints in the system be decided, and then the algorithms developed for automatically assigning the constraints are presented. Also described are the criteria followed that lead to an automatic generation of dimensions, as well as to equivalent and alternative dimensioning. Finally, a series of examples are presented to show the possibilities of the developed methodology.
