Every mechanical part is fabricated with variations in its size and shape, and the allowable range of the variation is specified by the tolerance in the design stage. Geometric tolerances specify the size of each shape entity itself or its relative position and orientation with respect to datums while considering their order of precedence. It would be desirable if the assemblability of parts could be verified in the computer when the tolerances on the parts are stored together with the

This method determines the assemblability by subdividing the range of relative motion between parts until there exists the subdivided region that does not cause the interference.
