面向ISO129-5的金属构件三维标注

3-D Dimensioning of Structural Metal Work for ISO129-5

在中国主持制定ISO129-5国际标准的过程中,需要满足产品设计数字化、三维化的要求。分析了技术产品文件领域标准的发展趋势,明确了三维标注的基本要求。介绍了兼顾二维与三维表达的金属构件标准。介绍了运用三维标注工具,对标准可行性与合理性的验证情况。

In the process of developing ISO129-5 under the leadership of China,it is necessary to meet the requirements of digital and 3-D product design.This paper analyzes the development trend of standards in the field of technical product documents,and clarifies the basic requirements of 3-D Dimensioning.Introduces the standard of structural metal work,which takes into account two-dimensional and three-dimensional expression.Introduces the verification of the feasibility and rationality of the standard by using the 3D annotation tool.
