标准摘要
[中文适用范围]： 本文件确立了适用于所有学科和行业的二维技术图纸尺寸和相关公差表示的一般原则，也可应用于三维应用。 本文件不涵盖尺寸公差的应用及其含义。关于公差原则，请参见ISO 14405-1。本文件仅可用于描述图纸的名义模型，而不适用于用于公差目的的非理想表面模型（皮肤模型）（有关公差规范的更多信息，请参见规范性引用或参考书目中列出的GPS标准列表）。 考虑到ISO 14405系列，当应用于尺寸时，公差指示的表示是明确的，而当尺寸不是尺寸时则是不明确的。 本文件中提出的所有规则适用于任何类型的图纸（参见ISO 29845）。 此外，本文件引入了属性指示器、展开长度、之间、表面指示器、标志注释和文本指令的概念。 所有图形仅以二维视图显示。 有关建筑工程的其他信息和详细信息，请参见ISO 6284。 [外文原描述]： ISO 129-1:2018 establishes the general principles for presentation of dimensions and associated tolerances that apply to 2D technical drawings in all disciplines and trades but which can also be applied to 3D applications. ISO 129-1:2018 does not cover the application of dimensional tolerances and their meaning. See ISO 14405‑1 for tolerancing principles. This document can only be used to describe the nominal model of a drawing, not the non-ideal surface model (skin model) used for tolerancing purposes (for more information on tolerancing specifications, see the list of GPS standards listed as normative reference or as bibliography) Considering the ISO 14405 series, the presentation of tolerance indication is unambiguous when it is applied to a dimension which is a size and ambiguous when the dimension is not a size. All rules presented in this document are available for any type of drawing (see ISO 29845). In addition, this document introduces the concept of property indicators, developed length, between, surface indicators, flag notes and textual instructions. NOTE 1 All figures are shown in 2D views only. NOTE 2 Additional information and details for construction engineering are given in ISO 6284.
