ISO 1101:2017定义了工件几何规范的符号语言及其解释规则。 它为几何规格提供了基础。 本文档中的图示旨在说明如何使用可见注释（包括例如TED）完全指示规范。 注1:第2条和表3和4中引用的其他国际标准提供了有关几何公差的更多详细信息。 注2本文件给出了几何规格的显式和直接指示的规则。或者，可以根据ISO 16792通过将其附加到3D CAD模型间接指示相同的规格。在这种情况下，可以通过查询功能或模型上的其他信息询问来获取规范的某些元素，而不是使用可见的注释来指示

ISO 1101:2017 defines the symbol language for geometrical specification of workpieces and the rules for its interpretation. It provides the foundation for geometrical specification. The illustrations in this document are intended to illustrate how a specification can be fully indicated with visible annotation (including e.g. TEDs). NOTE 1 Other International Standards referenced in Clause 2 and in Tables 3 and 4 provide more detailed information on geometrical tolerancing. NOTE 2 This document gives rules for explicit and direct indications of geometrical specifications. Alternatively, the same specifications can be indicated indirectly in accordance with ISO 16792 by attaching them to a 3D CAD model. In this case, it is possible that some elements of the specification are available through a query function or other interrogation of information on the model instead of being indicated using visible annotation
