ISO 13567-1:2017确立了CAD文件中图层结构的一般原则。图层用于控制可见性以及管理和交流CAD文件数据。层名称用于表示此结构。 这些原则适用于参与编制和使用计算机系统技术文件的各方。尽管这些原则主要针对用户，但CAD系统开发人员应提供能够实施和支持ISO 13567-1:2017的软件工具。另一个重要用途是在第三方生产的组件库中构造数据。

ISO 13567-1:2017 establishes the general principles of layer structuring within CAD files. Layers are used to control visibility and to manage and communicate CAD file data. Layer names are used to represent this structure. The principles are applicable to all parties involved in preparing and using technical documentation on computer systems. Although these principles are primarily for users, CAD system developers are expected to provide software tools capable of implementing and supporting ISO 13567-1:2017. An important use is also to structure data in component libraries produced by third parties.
