TS EN ISO 13567-2

TS EN ISO 13567-2 is the second part of the standard family that addresses concepts, format, and codes for organizing and naming CAD layers in construction documentation. It focuses on how layer information is structured so drawings and model data can be used more consistently for communication and management across a project.

Why layer organisation matters in construction CAD

In general technical practice, layers are used to separate CAD content by discipline, object type, system function, or other classification criteria. This helps architectural, structural, mechanical, and electrical information coexist in the same project environment while remaining readable, manageable, and easier to exchange. The standard’s subject is the organisation of that layer information into a common language for project participants.

Concepts, format and codes covered by this part

Based on the title and scope, this part covers the concepts, format, and codes used for CAD layers in construction documentation. In other words, it is not only about naming layers, but about the structure behind the naming scheme itself. Code-based layer structures support mapping between different offices and software environments. However, this record does not state a detailed prescribing method, numeric limits, or a single mandatory implementation model for every project.

• Aims to make CAD layers orderly and distinguishable for project information.
• Supports a shared classification logic for communication and management in construction documentation.
• Addresses the relationship between concepts, format, and codes in layer naming.
• Provides a general framework that helps align architectural, engineering, and production data.
