Representing Geometric Knowledge in Architectural Design

Geometric knowledge is essential to architectural design. A new method of geometric computing is proposed in this paper, in which geometric decision making in architectural design process can be represented naturally. I begin by discussing characteristics of geometry in the architectural design process and making clear the issues in the graphic libraries which have been used as a substitute in current CAD/CG systems. Then, I mention how to represent the spatial geometric primitives and operations from the view of knowledge in algebraic geometry. It is not sufficient for the architectural design process to represent geometric primitives and operations, and a model of geometric decision making is presented to manage the dynamism of the design process. I also explain the interaction between the presented geometric decision model and the architectural model which was proposed as the framework to develop our knowledge-based computer-aided architectural design system
