We would tasks occur near the conclusion of a larger argue, however, that most of these recent design process. In fact, most of the artistic developments have failed to tap the potential and intellectual challenges of an architectural design have already been resolved by the time the designer sits down in front of a computer.

Nature of the Architectural
Design Process and
Architectural design is an iterative, visual process -- one that involves thinking and exploring in pictorial or symbolic representations. $teven Coons described the creative and complex acrivity of design as follows: "It is typical of the design process that such iterations -- from concept, through analysis, evaluatJon of the analysis, decision to modify the concept, and finally to a new concept -- form loops that are traversed again and again, until eventually the designer judges the design adequate to satisfy some sca/eor scales of value judgment" [I] Throughout the design process, designers employ a range of representational media and conventions to explore, assess and refine their ideas. Initially, these representations may be small diagrammatic sketches intended to stimulate the imagination, test initial thoughts and concepts and generate a series of alternatives. As a design concept is selected for clarification and development, the representations chat designers employ to study the idea also become more...
