为关联接头间隙和目标尺寸以及在尺寸协调（包括模块化协调）范围内预测配合提供了基础。用于组件制造商在确定标准组件的目标尺寸时使用，以及建筑设计师在确定现场施工的目标尺寸、评估标准组件的适用性或确定非标准组件的标准尺寸时使用。

Provides a basis for relating joint clearances and target sizes and for the prediction of fit within the context of dimensional coordination, including modular coordination. Is intended for use by component manufacturers when determining target sizes for standard components and by building designers when determining target sizes for construction on site, assessing the applicability of standard components or determining target sizes for non-standard components.
