完整的设计通常根据零部件和装配关系来指定机械系统。每个零件都有一个完全定义的名义或理想形式和明确定义的材料属性。公差用于允许部件的形状和特性的变化，也用于允许装配关系的变化。因此，系统及其所有部件的几何形状和材料属性都被完全定义（至少在原则上）。尽管材料的重要性显而易见，但我们还是将重点放在几何学上，原因将变得显而易见。
A complete design usually specifies a mechanical system in terms of component parts and assembly relationships. Each part has a fully defined nominal or ideal form and well defined material properties. Tolerances are used to permit variations in the form and properties of the components, and are used also to permit variations in the assembly relationships. Thus the geometry and material properties of the system and all of its pieces are fully defined (at least in principle). Henceforth we shall focus on geometry and, for reasons that will become evident, will not deal with materials despite their obvious importance.
