title	Modelling multiple views of design objects in a collaborative CAD environment
source	Computer-Aided Design, Vol. 28 (3) (1996) pp. 193-205
summary	Collaboration between designers in different disciplines is an increasingly important aspect in complex design situations, as exemplified in the AEC domain. CAD systems are essential for handling this complexitybut current CAD modelling technology is directed towards the production of a single product model. In the AEC environment, many disciplines are involved, each with its own concept of the design object. Eachsuch concept must be accommodated in any representation. This paper presents the ideas behind the representation of multiple concepts from an underlying description of a design such that the inter- andintra-discipline views of that design can be formed dynamically. These ideas are based on different functional contexts. Functional subsystems are introduced as an adjunct to design prototypes. An example showshow these functional subsystems are related to the design elements and how they allow for the formation of the various concepts. Thus the representation of the functional properties of design objects is theunderlying basis for the formation of different concepts.

title	The generation of form using an evolutionary approach
source	J.S. Gero and F. Sudweeks (eds), Artificial Intelligence in Design Ì96, 643-662
summary	Design is a purposeful knowledge-based human activity whose aim is to create form which, when realized, satisfies the given intended purposes.1 Design may be categorized as routine or non-routine with the latter further categorized as innovative or creative. The lesser the knowledge about existing relationships between the requirements and the form to satisfy those requirements, the more a design problem tends towards creative design. Thus, for non-routine design, a knowledge-lean methodology is necessary. Natural evolution has produced a large variety of forms well-suited to their environment suggesting that the use of an evolutionary approach could provide meaningful design solutions in a non-routine design environment. This work investigates the possibilities of using an evolutionary approach based on a genotype which represents design grammar rules for instructions on locating appropriate building blocks. A decomposition/aggregation hierarchical organization of the design object is used to overcome combinatorial problems and to maximize parallelism in implementation.
