ISO 16792-2021 pdf free download.Technical product documentation – Digital product definition data practices.
This document specifies requirements for the preparation, revision and presentation of digital product definition data, hereafter referred to as data sets, complementing existing standards. It supports two methods of application: 3D model-only and 3D model with 2D drawing in digital format. The structure of this document presents requirements common to both methods followed by clauses providing for any essential, differing requirements for each method. Additionally, its use in conjunction with computer- aided design (CAD) systems can assist in the progression towards improved modelling and annotation practices for CAD and engineering disciplines, as well as serving as a guideline for CAx software developers.
The actual definitions for the interpretation, in particular the ISO TPD and ISO GPS rules, are taken from the original definition standards. e.g. ISO 129-1 and ISO 1101.
When the term model is used in this document it applies to both design models and annotated models.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 10209 and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1 General terms and definitions
3.1.1 absolute coordinate system
initial model coordinate system in the active CAD model used to define the location of digital elements in that CAD model
Note ito entry: The active CAD model may be a part, subassembly or assembly.
Note 2 to entry: This absolute coordinate system has absolute origin of 0,0,0.
3.1.2 offset section
stepped cutting plane to include features not located in a straight cutting plane
Note I to entry: 2D offset section views are drawn as if the offsets were in one plane, and the offsets are not indicated in any manner in the section views. 3D offset section views are shown by cutting through the part in an offset manner.
3.1.3 product definition data set data set
collection of one or more computer files that discloses (directly or by reference), by means of graphic or textual presentations, or combinations of both, the physical and functional requirements of a product
3.1.4 user-defined coordinate system
model coordinate system which is created in the CAD model by the user in addition to the absolute coordinate system
3.2 Classification codes for drawings and data sets (see AnnexE)
3.2.1 classification code
designation assigned to product definition data that defines what data are included within the drawing, data set or both
Note ito entry: A drawing can be in either physical or electronic format.
