Abstract
In current BIM standards and today's BIM practice, drawings and models are used side-by-side. While respecting the de-facto coexistence of models and drawings, the induced information redundancy results in challenges for proper information management. It is thus desirable to establish and maintain deep links between the model elements and the corresponding drawing elements, as this allows for bi-directional navigation across the model/drawing boundaries and enables accessing non-geometrie model information from the drawing. In addition, consistency checking and preservation become more reliable. The paper specifies the requirements and semantics of the linking mechanism and discusses different technical implementations. Major emphasis is placed on the concept of the Information Container as defined by ISO 21597 which allows to represent and exchange linked models in a vendor-neutral format, but alternative mechanisms are also investigated. The paper finishes with presenting a feasibility case study.
