Create a mapping file and update all the files. Extract all the layer names from the existing file to excel. However mapping from one system to another is straight forward and I have written routines to map 1000s of drawing to do this. This is why AECuk and others haven't updated and why chaos exists. Then NBS and CPIC released Uniclass version 2 for testing but this received a lot of kickback so wasn't released formally. Just to confuse the situation Uniclass was rewritten from version 1 to version 1.4 which was released. PAS 1192-2:2013 then stated that you must use Uniclass and follow the linework conventions from BS8541 etc. The BSI then published other standards such as BS854:20121 parts 1 to 4 but specifically Part 2 dealt with graphic representation and symbols including line work displays. Such as Cisfb / Uniclass / AECuk versions etc.

OK BS1192:2007 provides a framework and allows the use of various classification systems. Uniclass 2 has not been officially sanctioned so I will release this when it is launched. Please note that the BS1192:2007 version is based upon the requirements of PAS1192-2 2013 which is the latest version to comply with HMG requirements as opposed to AEC UK which does not comply. Samples of the application can be downloaded from my website: I have therefore captured these and documented into a data file that is used by the OCSL LayerMaker application Whilst the US National CAD Standard may not assign colors or pen weights the implementations within AutoCAD Architecture and Revit do. It also maps Colours or Colors depending upon which side of the pond you sit and also line weights.

OCSL Layer Maker provides options to produce Layers based upon the following International Layer Standard Formats:

I presently have an Application going through the exchange store that has been used by specific Clients for many years for creating layers to a specific standard. In my web searches I found an American company which sells ( expensive) layer manager software based on the American CAD standards system - providing fool proof and universal layer management - I haven't been able to find any UK companies offering this kind of product? Is there company in the UK which sell/provides template files with Cad standard layers already loaded? I do appreciate any enlightenment as to current practice in this area. The AEC standards are also limited in that they do not specify line weights, model space drafting colours etc etc for each layer therefore leaving a huge amount of individuality in producing template drawings. Am I correct in assuming that each architects office is basically reinventing the same wheel in that they are each producing individual Cad standard manuals - all based on either AEC (UK) standards or similar? Its a huge job to take all the AEC(uk) layer names, for example, and create new templates with these.
