1.1本指南涵盖了尺寸协调在建筑设计和直线建筑部件和系统制造中的应用。建议使用最少数量的首选尺寸，以提供一系列替代方案，从而在设计、详细设计、生产和施工方面实现经济效益。如果可以建立文件、制造、安装和维护方面的优势，但不是为了消除不协调的定制设计，则应使用尺寸协调。 1.2具体而言，指南涵盖: 1.2.1尺寸协调中使用的术语说明。 1.2.2建筑设计中建筑部件和系统尺寸协调的依据。 1.2.3建筑部件和系统协调的首选水平和垂直尺寸。 1.3除一般原则外，本指南未说明建筑构件的首选尺寸和尺寸。 1.4给出了模块化绘图实践中尺寸标注的基本准则。 1.5在可行的情况下，考虑了国际标准化组织（ISO）制定的国际标准中的建议。

1.1 This guide covers the application of dimensional coordination in building design and the fabrication of rectilinear building parts and systems. A minimum number of preferred dimensions are recommended to give a range of alternatives that should result in economies in design, detailing, production, and construction. Dimensional coordination should be used where benefits in documentation, fabrication, installation, and maintenance can be established, but is not intended to eliminate uncoordinated custom design. 1.2 Specifically, the guide covers: 1.2.1 Descriptions of terms used in dimensional coordination. 1.2.2 The basis for the dimensional coordination of building parts and systems in the design of buildings. 1.2.3 Preferred horizontal and vertical dimensions for building parts and for the coordination of systems. 1.3 This guide does not state preferred dimensions and sizes for building components, except for general principles. 1.4 Basic guidelines for dimensioning in modular drawing practice are given. 1.5 Where practicable, recommendations in international standards prepared by the International Organization for Standardization (ISO) have been taken into account.
