title Design Reasoning Without Explanations
source AI Magazine. 1990. vol. 11: pp. 72-80
summary This paper proposes 'connectionism' as an alternative to 'classical cognitivism' in understanding design. In the process the author considers the difficulties encountered within a particular view of the role of explanations and typologies. Connectionism provides an alternative model that does not depend on the articulation of explanations and typologies

title Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source New York: The Metropolitan Museum of Art
summary The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

title Computing and Design in the Canadian Schools of Architecture and Landscape Architecture: A Proposed Research Agenda for Integrated CAD & GIS in the 1990's
source New Ideas and Directions for the 1990ís [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 227-244
summary Conventional computer systems currently used by architecture and landscape architecture are not addressing complex decision making, system interface, dynamic manipulation and real time visualization of data. This paper identifies a strategy by which Canadian Schools could form a supportive network, incorporate and expand their research development. Within this larger framework schools would have better tools, a larger research base and access to funding as a group. The following discussion is an idea of what we at the Canadian Schools need to do differently over the next five years in our research and teaching in order to make a unique contribution to our fields.

title CAD Tools for Systems Theory and Bottom Up Design
source New Ideas and Directions for the 1990ís [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 209-226
summary The use of CAD is investigated in the teaching of systems theory to a fourth year group of design students. A comparison is made between the CAD group using MacArchitrion and a non-CAD group using traditional design methods. The paper includes a discussion of the meaning of systems design theories, relates the CAD and non-CAD student design methods and illustrates the results. It also includes recommendations for improvements so the computer can become more effective in this type of design teaching. Finally, it concludes with recommendations from the students at the end of the semester project. The basic premise for the CAD design group is that computers should encourage students to understand and use systems design theory.

title Interactive design of parameterized 3D models by direct manipulation
source Delft University of Technology
summary The practical applicability of a computer-aided design system is strongly influenced by both the user interface and the internal model representation. A well designed user interface facilitates the communication with the system by offering an intuitive environment for for specification and representation of model information. An internal model representation, capable of storing geometric, topological and hierarchical dependencies between components in a model, increases the efficiency of the system by facilitating modification and elaboration of the model during the different stages of the design process. The subject of this thesis is the integration of a high level parameterized model representation with direct manipulation interface techniques for the design of three-dimensional objects. A direct manipulation interface enables the user to specify a model by interaction on a graphical representation, as an alternative for an abstract and error-prone apha-numerical dialogue style. A high level model representation is obtained by using a procedural modeling language with general purpose control structures, including arithmetic and logical expressions, repetition, conditionals, functions and procedures, and dedicated data types such as coordinate systems, geometric primitives and geometric constraints. The language interpreter is interconnected with a graphical interface, an incremental constraint solver and a geometrical modeler, using visual programming techniques. The developed techniques are implemented in a modeling system called GeoNode. The system incorporates paradigms of object-oriented design, with respect to both the user interface and to the system implementation. The applicability of the presented techniques is illustrated by examples in application domains such as solid modeling, kinematic analysis, feature modeling and top-down design.

title SEED: A Software Environment to Support the Early Phases in Building Design
source Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title Generative and Evolutionary Techniques for Building Envelope Design
source International Conference on Generative Art
summary The authors have been involved in the use of generative techniques for building envelope design since 1968 and the use of genetic algorithms since 1990. Recent work has focused on incorporating optimisation functions into form generating processes in order for new forms responding to varied design environments to be created and determined. This paper will summarise the authorsí previous work in this field and explain the theory behind this approach, and illustrate recent developments. While the initial implementation of a new building envelope design system is reported in more details in a related paper at this conference, this paper outlines its main features and points out the direction at which it is to be fully developed and further improved.

summary Craft oriented culture was eventually displaced by mass-production, and it was not until the early 1990ís when a new paradigm began to emerge, one of infinite customer driven flexibility. Mass customization promises a flexible and efficient mode of production for customized parts or services at low cost. The catalyst for such a revolution has been computer-aided design and computer controlled manufacturing.

title Analysis of design communication with and without computer mediation
source Proceedings of Co-designing 2000, pp. 329-337
summary With recent developments in CAD and communication technologies, the way we visualise and communicate design representations is changing. A matter of great interest to architects, practitioners and researchers alike, is how computer technology might affect the way they think and work. The concern is not about the notion of 'support' alone, but about ensuring that computers do not disrupt the design process and collaborative activity already going on (Bannon and Schmidt, 1991). Designing new collaborative tools will then have to be guided by a better understanding of how collaborative work is accomplished and by understanding what resources the collaborators use and what hindrances they encounter in their work (Finholt et al., 1990). Designing, as a more abstract notion, is different than having a business meeting using video conferencing. In design it is more important to 'see' what is being discussed rather than 'watch' the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the method with which it is communicated (See Kvan, 1994). Similarly, we believe that by using text instead of audio as a medium for verbal communication, verbal representations can then be recorded alongside graphical representations for later retrieval and use. In this paper we present the results of a study on collaborative design in three different environments: face-to-face (FTF), computer-mediated using video conferencing (CMCD-a), and computer-mediated using "talk by typing" (CMCD-b). The underlying aim is to establish a clearer notion of the collaborative needs of architects using computer-mediation. In turn this has the potential in assisting developers when designing new collaborative tools and in assisting designers when selecting an environment for a collaborative session.

title A language of Abstract Floor Plans
source Environment and Planning B: Planning and Design. 1990. vol. 17: pp. 173-204 : ill. includes bibliography
summary Theoretical and experimental results from the implementation of a system for computer-aided floor-plan design are reported. The system is based on a potentially exhaustive search for solutions that satisfy user-specified constraints, but the paper concentrates on techniques for limiting and guiding the search. The emphasis is on two aspects of floor-plan design: the use of a formalized concept of sketching, and the language in which design constraints are specified by the user. A well-defined concept of abstract draft plans is achieved by limiting corner coordinates to intervals, rather than single numbers. Mathematical properties of draft and their defining constraints as derived from the user's constraints are outlined, and the role of drafts in computer- aided floor plan design is investigated and illustrated by examples. The specification language is based on a small set of primitives whose combined power of expression is also illustrated. The syntax and semantics of the language are formally defined (in two appendices), and the importance of careful development of languages for future design automation is pointed out

title The Pleated Cape: From the Mass-Standardization of Levittown to Mass Customization Today
source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 426-439
summary In the 1950ís, the Levitts put mass-production and the reverse assembly line into use in the building of thousands of single-family houses. However, the lack of variation that made their construction process so successful ultimately produced a mundane suburban landscape of sameness. While there were many attempts to differentiate these Levitt Cape Cods, none matched the ingenuity of their original construction process. The notion of mass-customization has been heavily theorized since the 1990ís, first appearing in the field of management and ultimately finding its way into the field of architecture. Greg Lynn used mass-customization in his design for the Embryological House in which thousands of unique houses could be generated using biological rules of differentiation (Lynn 1999). Other industries have embraced the premise that computer-numerically-controlled technologies allow for the production of variation, though it has not been thoroughly studied in architecture. While digital fabrication has been integral in the realization of several high-profile projects, the notion of large-scale mass-customization in the spec-housing market has yet to become a reality. Through the execution of an addition to a Cape Cod-style house, we examine the intersection between prefabricated standardized panels and digital fabrication to produce a mass-customized approach to housing design. Through illustrations and a detailed description of our design process, we will show how digital fabrication technologies allow for customization of mass produced products.

title Design Decision Making Using Pareto-Optimal Dynamic Programming
source Berlin: Springer- Verlag, 1990. pp. 376-396
summary When designing using the systems approach, the given system is decomposed into a number of subsystems, and for each subsystem a set of feasible alternatives is selected by the designer. A building design example is presented in which it is demonstrated that sufficient relevant solutions are generated in one pass of the dynamic programming procedure to give a good approximation to the Pareto set, thus offering designers sufficient choice in making a final selection. The relevant information is displayed in an intelligent manner so that designers can either make a final decision or else perceive what extra information they require

title Image Sampling
source From Research to Practice [ACADIA Conference Proceedings] Big Sky (Montana - USA) 4-6 October 1990, pp. 21-28
summary Analogous to music sampling, in which sounds from the environment are recorded, distorted and used in unique ways to create music, "image sampling" is the visual equivalent of a sound bite used to create new visual forms, textures, patterns and types of architecture. Through the use of image sam ling, a designer can accurately record and digitize images from the existing visual world: rom the physical (built or natural) context of the site, from history (a specific building " or a significant architectural monument) or from previous work produced by the designer. The digital scanning process makes design information equal and uniform, as it converts all images to dot patterns of varying color. As a result the image can be transformed through numeric operations (even when the algorithms are transparent to the end user). The recorded images can therefore be fragmented, combined, distorted, duplicated, tweened, or subjected to random automated operations. Because computer images are digital, they facilitate modification and transformation, unlike their analog counterparts. Merging video and image processing capabilities with three-dimensional modeling permits the designer to collage visual information into new and readily editable architectural proposals. Combining image samples into new architectural concepts expands the scope of potentials available to the architect and also raises fundamental questions about issues of originality, creativity, authenticity, and the nature of the design process itself. What is original work, created by the designer, and what is merely re-used? The discussion of new digital imaging eventually leads to questions about design theory and ethics, in addition to those associated with computer technology and architectural form. As one works in any new medium, including the digital environment, many questions are raised about its impacts on design. Much of what is presented in this paper are early speculations on the implications of the digital technology and its influence on architecture.

title Serial Sketching : Feedback Mechanisms in Designing
source System Research, Informatics and Cybernetics, International Conference (5th : 1990 : Baden- Baden, Germany). For Cognition in Design Session, abbreviated paper
summary Designing is seen as a process of small-step transformations of partial images of a still non-existing entity. The ultimate objective of the process is the production of sufficiently coherent and comprehensive representations of design entity, so as to allow the construction of a visual simulation of it, physically or mentally. Sketching is universally used by designers throughout the front-edge of the process as a major tool for the generation, transformation, and representation of images. Serial sketching, often executed on consecutive layers of transparent paper, allows the designer to experiment with changes while fully controlling previous versions of an image. Feedback from each version informs subsequent transformations. This typical characteristic of design behavior is explored through on-line studies quotidian design activity and is compared to modes of production in other domains

title Building Representation within a Component Based Paradigm
source From Research to Practice [ACADIA Conference Proceedings] Big Sky (Montana - USA) 4-6 October 1990, pp. 117-127
summary This paper questions the use of a 2-dimensional medium to convey 3-dimensional information about design intent and proposes a computer-aided paradigm that could radically alter the way in which buildings are designed and built. The paradigm is centered about the accurate and rational representation (Rush, 86) of each individual component that makes up a building in a single, shared, computer based model. The single model approach couples the accurate physical representation of components with the accurate representation of technical information and knowledge about the assemblies of building components. It is anticipated that implementation of this approach will result in fewer communication problems that currently plague the fragmented process of practicing in the professions of architecture and engineering. The paper introduces the basic concepts within the paradigm and focuses on the development of intuitive, reasoning about the component-based design suitable for incorporation in a computer-aided setting.
