本文件规定了数字产品定义数据（以下简称数据集）的编制、修订和表示要求，以补充现有标准。它支持两种应用方法:仅3D模型和带有数字格式二维图纸的3D模型。本文件的结构介绍了两种方法的共同要求，并附有条款，规定了每种方法的任何基本、不同的要求。此外，将其与计算机辅助设计（CAD）系统结合使用，有助于CAD和工程学科的建模和注释实践的改进，并为CAx软件开发人员提供指导。 解释的实际定义，尤其是ISO TPD和ISO GPS规则，取自原始定义标准e。 g、 ISO？129-1和ISO？1101。 当本文档中使用术语模型时，它同时适用于设计模型和注释模型。

This document specifies requirements for the preparation, revision and presentation of digital product definition data, hereafter referred to as data sets, complementing existing standards. It supports two methods of application: 3D model-only and 3D model with 2D drawing in digital format. The structure of this document presents requirements common to both methods followed by clauses providing for any essential, differing requirements for each method. Additionally, its use in conjunction with computer-aided design (CAD) systems can assist in the progression towards improved modelling and annotation practices for CAD and engineering disciplines, as well as serving as a guideline for CAx software developers. The actual definitions for the interpretation, in particular the ISO TPD and ISO GPS rules, are taken from the original definition standards, e.g. ISO？129-1 and ISO？1101. When the term model is used in this document it applies to both design models and annotated models.
