title Toward Making the Language of CAAD Match the Language of Architecture: A Protean Elements Approach
source Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 93-100
summary Both in education and in practice, architecture is experiencing a division between designers and "CAD specialists." One reason for the division may be the inherent division between design concepts and CAD concepts. In a very real sense, computer use and design utilize different languages. Becoming an expert in the "craft" of CAD means having to learn to recognize and manipulate a different set of conceptual elements than is used in design. The set of concepts we use affects our thought and behavior incredibly deeply, and translation from one set of concepts to another has significant cognitive cost. This paper discusses the mismatch between architectural and CAD concepts, and proposes protean elements as a solution to the problem. Protean elements are CAD system elements which correspond to architectural elements and have attributes appropriate for the elements they represent. They can be gradually refined in a top-down manner, without demands for certain pieces of missing data, or requirements for "correctness." The goal is to help CAD systems come closer to speaking the same language as architects. A test implementation of a system based on protean elements is currently underway, and aspects of this implementation are discussed.
