    • 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.
    • 用于基于设计数据执行公差分析的公差分析装置包括组装定义单元,其允许用户制作组件定义并且为组成部件定义自由度,以及确定单元确定对应于计数的数据类型 基于数据确定参考表的值。 确定单元通过对组成部件的组装位置具有相同方向的法线数量,法线方向的平移自由度的约束程度以及围绕垂直于方向的轴线的受限旋转自由度进行计数来获得计数值 基于组件定义和组成部件的自由度的正常。 该装置还包括输出单元,其输出由确定单元确定的基准类型。
