ISO 13567

ISO 13567 is an international Computer-aided design (CAD) layer standard.

Standard parts[edit]

The standard is divided into three parts:

  • ISO 13567-1:2017[1]
    • Technical product documentation — Organization and naming of layers for CAD — Part 1: Overview and principles
  • ISO 13567-2:2017[2]
    • Technical product documentation — Organization and naming of layers for CAD — Part 2: Concepts, format and codes used in construction documentation
  • ISO/TR 13567-3:1999 (withdrawn September 2015)[3]
    • Technical product documentation — Organization and naming of layers for CAD — Part 3: Application of ISO 13567-1 and ISO 13567-2

Standard has been developed by Technical Committee TC 10 (Technical product documentation) Subcommittee SC 8 (Construction documentation); Refer. ICS: 01.110; 35.240.10.

Structure of layer names[edit]

CAD layer names are structured as a series of mandatory and optional fixed length fields, composed as a continuous alpha-numerical text string.

Mandatory fields[edit]

Special characters[edit]

- (hyphenation) not used field _ (underscore) relative to all possible characters 


Resulting length[edit]

In practice, application of ISO 13567 fields can lead to short names (only mandatory fields), or much longer names (use of some or all optional fields in complex projects).
