Design information and dimensional coordination
The AEC (UK) CAD Standards Initiative was formed in 2000 to improve the process of design information production, management and data exchange. The initiative addressed CAD layering conventions as the primary concern for users of design data. As design needs and technology have developed, the scope has expanded to cover other aspects of design data production and information exchange. The AEC (UK) CAD Standard Basic Layer Code was released in 2001, with an Advanced Code released in 2002.
