    • A tolerance analyzing apparatus for performing a tolerance analysis based on design data includes an assembly definition unit that allows a user to make an assembly definition and define a degree of freedom for a constituent component, and a determination unit determining a datum type corresponding to a count value based on a datum determination reference table. The determination unit obtains the count value by counting a number of normals having the same direction at an assembly location of the constituent component, a constrained degree of translational freedom in the normal direction, and a constrained degree of rotational freedom about an axis perpendicular to the normal based on the assembly definition and the degree of freedom of the constituent component. The apparatus also includes an output unit that outputs the datum type determined by the determination unit.

    • It is an object of the present invention to reduce setting errors of the degrees of freedom in an assembly definition of a component manufactured by a CAD device. In an assembly definition database, a plurality of assembly definition data is registered in advance, each of which includes a name of assembly definition, a definition order, a shape of the definition part, data expressing the degrees of freedom and the like. A determination unit in the CAD device compares shape data of the definition part in the assembly definition data selected by an operator with shape data of the specified set-up part of a component, and determines whether or not they match each other. When the above shape data matches, the degrees of freedom in the assembly definition data is set as the degrees of freedom of the specified part of the component.
