This part of ISO 129 establishes the general principles of dimensioning applicable for all types of technical drawings.
NOTE The figures in this part of ISO 129 merely illustrate the text and are not intended to reflect actual usage.
Consequently, they have been simplified to indicate only the relevant general principles applicable in any technical area.
Additional and more specific rules and details about the use of dimensioning for construction engineering are given in ISO 6284. For mechanical engineering, they will be given in the future ISO 129-2.
