How Layer Standards Determine Layer Name

When you create a new layer using a layer standard, the layer name has a number of parts separated by delimiters (for example, hyphens). Each part of the layer name is determined by rules specified in a corresponding field of the layer standard.

For example, the AIA 2nd Edition layer standard includes five fields that form each new layer name: Discipline Designator, Major, Minor 1, Minor 2, and Status. Each field is separated by a hyphen (?) delimiter, as in the following example:

(Discipline Designator) – (Major) – (Minor 1) – (Minor 2) – (Status)

A layer in your drawing with a Discipline value of “A,” a Major value of “Wall,” a Minor 1 value of “Full,” a Minor 2 value of “Abov” and a Status value of “D,” to denote a demolition layer, would be named A-WALL-FULL-ABOV-D.

You can edit the layer standard definition to change these rules.

You can override the information in each field to change the way a layer standard creates a layer name by specifying layer key overrides.

Layer Standards Included with the Layer Properties Manager

AutoCAD Architecture 2022 toolset provides industry-standard layering conventions including: AIA 2nd Edition, BS1192 Descriptive, and BS1192 – AUG Version 2. Additional international layer conventions are also provided including: DIN 276, ISYBAU Long Format, ISYBAU Short Format, and STLB. Each layer standard contains specific information organized in fields. You can specify how the information appears in each field by changing the values in the layer standard fields.
