This part of GB/16901 specifies the requirements for graphic symbols described in the reference symbol library in the computer electronic file format and the requirements for their exchange between computer-aided tools. This part is applicable to the reference symbol library and can be used as the basis for the preparation of technical documents, the exchange of files and graphic symbol libraries between computer-aided tools. This part does not contain the physical file format specifications required for exchange.
class="f14" style="padding-top:10px; padding-left:12px; padding-bottom:10px;"> GB/T16901 "Rules for the Representation of Graphical Symbols for Technical Documents" is divided into 3 parts:
———Part 1: Basic rules;

———Part 3: Classification and coding of connection points and networks. This
part is the second part of GB/T16901.
This part is drafted according to the rules given in GB/T1.1-2009.
This part is revised and adopted by IEC81714-2:2006 "Rules for the Representation of Graphical Symbols for Product Technical Documents Part 2: Specification for the computer electronic file format of graphic symbols including graphic symbols in the reference symbol library and their exchange requirements" using the translation method. ||tt ||

In order to produce stable and high-quality products at a low cost and in a short time, we should pay attention to the following aspects: 1) The diagram contains many pictograms and symbols. Each symbol involves the general expression of the information of the object. In order to make this information readable, you need to pay attention to the different flows of information in the diagram and the overall interpretation of the diagram when making graphic symbols: 2) In order to reduce the load of drawing, all graphic symbols can be stored in the base symbol virtual mountain; 3) In order to minimize the operation of diagram data, only one base symbol should be used. In this way, the system does not need to use the instance of a graphic symbol defined in the database as a general symbol in the system, but only needs to use the corresponding symbol definition in the related reference symbol method:
The reference symbol in the database can be used to define the uncertainty of the environment in which the graphic symbol is defined. Therefore, when using the graphic symbol in the diagram, the data variables related to the object represented by the graphic symbol are assigned to their values ​​to connect the graphic symbol with the diagram. At this time, the missing data set by the graphic symbol definition in the reference symbol database is usually replaced by the valid data of the graphic symbol instance in the diagram. Only by making graphic symbols in a consistent way can the increasingly cross-industry interoperability standards be met in terms of diagram production and use of graphic symbols, and more requirements for the environment and data sharing are provided (see Appendix). To obtain consistent graphic symbols, reference symbols and reference symbol libraries can be used. Most of the graphic symbols in (1/ and IS) 11617 are used as the basis for reference symbols. However, the standard does not have any requirements for the effectiveness of the symbol in the computer-aided design system. This part defines the requirements for this purpose. For details, see Appendix A. The reference symbol library in the software can be used to provide a common understanding of the function of the product when working in a multi-point environment. Transformation mechanism:
Effective generation of symbol definition:
"- While increasing the blood support of the dynamic design concept, while maintaining good quality;--Supporting the reuse of graphic derivative symbols at different stages of its management by means of minimal size change, such as graphic shadow symbol adjustment, etc.:
-Control the existing functions of the Ax system
6 Symbols (including symbols in the reference symbol library) 6.1 General provisions
The following social supplementary period rules of this part are used to determine the management elements of the symbol. The rules of this part also apply to the basic screening number Graphic symbols and components of dreams.
A baseband symbol is equipped with some only the complete change of the case position to represent the method and the graphic crack in the article figure and the data associated with the represented object. In this part, the content of these positions will be visualized in the meaning area. The appendix of the standard gives the relevant data type and length recommendation of the positions that can be confirmed in this part. Note: If it can be explained, the non-center line given in the bed section shall be confirmed according to the center line of the material.
