ActiveTechnical product documentation—Requirements for model based definition—Part 2: Three-dimensional annotation
技术产品文件 基于模型定义要求 第2部分:三维标注
Application Summary AI generated
This standard specifies the requirements for applying three-dimensional annotations, such as dimensions, tolerances, and surface finishes, directly onto 3D digital models used in technical product documentation. It is applied in engineering design and manufacturing industries, particularly for computer-aided design (CAD) and product lifecycle management (PLM) systems, to enable model-based definition (MBD) workflows. The standard ensures consistent, unambiguous communication of product specifications without relying on traditional 2D drawings.
