Layer Standards

Implementing the BS1192:2007 Layer Standard
Whilst for many the perception of BIM was that there was no more need for Layers the reality is quite the opposite. The current British Standard for CAD Layering within the UK is BS1192:2007. Where specific BIM software does not support Layers then on export to CAD systems it must produce CAD data on the relevant BS1192:2007 layers.

This page provides some guidance on the implementation of the BS1192:2007 Layer standard, but for a more detailed description please refer to either BS1192:2007 itself or the supporting documentation produced by the BSI and links can by found on the British Standards pages on this site.

BS1192:2007 allows for the following fields to be included within any Layer Name:-

Classification / Element
 
Presentation

There are various methods of implementing the Layer standard within BS1192 which has led to inconsistences.

Therefore to aid with a common approach CPIC have provided a tool on their Web site to enable a common approach. This tool can be found at
