GB/T 24734.1-2009 Technical product documentation - Digital product definition data practices - Part 1. Terms and definitions
(ISO 16792.2006, Technicalproductdocumentation-Digitalproductdefinitiondatapractices, NEQ)
3 Terms and Definitions
GB/T 24734.1-2009 and established the following terms and definitions apply to this part of the GB/T 24734 of.
3.1
In the standard level representation of the functions required to identify the purpose and design details geometry modeling or display. Unless otherwise specified,
The maximum length of less than 0.5%, and the expression of functional purpose modeling or unwanted elements may not be displayed.
3.2
In the simplified representation level, only the basic shape of the part of the various parts, the part or assembly needs to be modeled or display. Chamfers, grooves, notches
And other elements, and does not require modeling or show internal details.
3.3
In the extended representation, all the parts, assemblies or models feature modeling or display should be able to show their full details. Satisfying work
Under the premise of energy required, modeling or accuracy may be lower than the actual display in the form of a part or feature of the model. Unless otherwise specified, less than the maximum
0.1% of the length of the element can not be modeled or display. Internal details of the limited volume only when necessary direction to the display.
Level 4 model representation
Level model representation divided into three.
a) represents a standard level;
b) simplified level representation;
c) extended representation.
