Abstract/Contents

Abstract: This paper presents an architecture and prototype test results of a computer-based system for assisting the conceptual phase of building design. The system uses 3D CAD to represent a graphic model of the facility design, and it builds a symbolic model of the form, function and behavior of the design. The system includes automated methods to analyze design behavior and compare predicted behavior with intended function. A virtual product model-based CAD system was implemented using the concept of interpretations. After drawing a design using 3D CAD. a designer interactively creates interpretation objects to express the meaning of the graphic representation with respect to a particular issue. The interpretation represents geometric and topological attributes of the features for use by automated design analysis tools. Interpretation objects unite support for graphically-oriented design thinking with support for automated symbolic reasoning. The paper includes an example building design scenario using the software prototype, illustrating how interpretation of the geometric model produces a symbolic model and supports multiple and changing analyses and evaluations during design. The system implements Circle Integration, and it is an example of Desktop Engineering. The system has been tested by students and practicing engineers.
