ISO 1101:2017定义了工件几何规格的符号语言及其解释规则。 为几何规范提供了依据。 本文件中的插图旨在说明如何通过可见注释（包括TED）充分说明规范。 注1:第2条、表3和表4中引用的其他国际标准提供了有关几何公差的更详细信息。 注2:本文件给出了明确和直接表示几何规格的规则。或者，根据ISO 16792，通过将相同的规范附加到3D CAD模型，可以间接指示相同的规范。在这种情况下，规范的某些元素可能通过查询功能或对模型信息的其他查询而不是使用可见注释来指示

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
