ISO 13567 - the proposed international standard for structuring layers in computer aided building design

Abstract: Layering is a widely used method for structuring data in CAD-models. During the last few years national standardisation organisations, professional association, user groups for particular CAD-systems, individual companies etc. have issued numerous standards and guidelines for the naming and structuring of layers in building design. Recently ISO has defined a draft international standard, ISO/DIS 13567, in order to increase interoperability betwen different CAD applications for building design.The principles which have been followed in the design of the draft standard are first presented, after which the paper describes the semantical organisation of the standard proposal and its default syntax. Important mandatory information categories deal with the party responsible for the information, the type of building element shown, and whether a layer contains the direct graphical description of a building part or additional information needed in an output drawing etc. Non-mandatory information categories facilitate the structuring of information in rebuilding projects, use of layers for spatial grouping in large multi-storey projects, and storing multiple representations intended for different drawing scales in the same model etc.Pilot testing of ISO 13567 is currently being carried out in a number of countries which have been involved in the definition of the standard. In the paper two implementations, which have been carried out independently in Sweden and Finland, are described. The paper concludes with a discussion of the possible benefits of the standard. Incremental development within the industry, is contrasted with the more idealistic scenario of building product models.
