A run time exchange of component information between CAD and object models: A standard interface
The Int. Journal of Construction IT 2(2), pp. 37-52
Integrated computer aided design could only occur in engineering once CAD systems could represent physical features and components rather than graphical primitives. In most dedicated CAD systems, the knowledge of a complete component exists only for the duration of each drawing command and the data stored in the database is simply a set of graphic primitives. This paper proposes an approach for real time information transfer from and to CAD systems based on a high level object representation of the design drawing. Drawing components are automatically identified and represented in an object hierarchy that reflects the 'part-of' relation between the various components including building spaces. Such hierarchies transfer an industry standard CAD system i.e. AutoCAD, into a high level object oriented system that can communicate with external applications with relative ease.
