title	Computer Integrated Design: Transformation as Process

summary	To bring together poetry, magic and science, to explore beyond preconceptions, to invent spaces and forms which re-form and inform man's experience, these are the possibilities of architecture. Computer integrated design offers a means for extending the search, one which integrates both conceptual and perceptual issues in the making of architecture. The computer may assist in generating constructs which would not have been created by conventional methods. The application of computer techniques to design has to date been focused primarily on production aspects, an area which is already highly organizable and communicable. In conceptual and perceptual aspects of design, computer techniques remain underdeveloped. Since the impetus for- the development of computer applications has come from the immediate economics of practice rather than a theoretically based strategy, computer-aided design is currently biased toward the replication of conventional techniques rather than the exploration of new potentials. Over the last two years we have been involved in experimentation with methodologies which engage the computer in formative explorations of the design idea. Work produced from investigations by 4th and 5th year undergraduate students in computer integrated design studios that we have been teaching at the University of Southern California demonstrates the potential for the use of the computer as a principal tool in the exploration of syntax and perception, space and program. The challenge is to approach the making of architecture as an innovative act, one which does not rely on preconceived notions of design.

summary	Transferring innovative university-based research results to the industry or practice that will ultimately use them is an arduous, time-consuming effort. One way to effect this technology transfer is to develop a demonstrable prototype product and then find or form a corporation that can expand the prototype into a full product and market it to the profession. Another way, which can shorten the transfer process, is to "sell" the idea, rather than the product, to a corporation that has the vision, the resources and the technical competency to support its development, with the intent to eventually market it. In this paper, we describe a case study of this latter approach, based on our seven year experience of researching, developing and transferring innovative architectural CAD technology. We describe the birth, growth, and maturity of Worldview, a computer-aided design and modeling system for use by architects. The project was initiated in 1983, and went through five software versions, numerous grants and grant extensions, two granting corporations, and extensive field testing. The software has developed into a mature system, with sufficient functionality appropriate for commercial distribution. The paper describes not only the factual chronology of the project, but also highlights the advantages and drawbacks of market-oriented university research. We conclude with suggestions as to how the process may be improved, and how problems and obstacles can be minimized.

title	Prior Knowledge in Design : A Dynamic Knowledge-based Model of Design and Creativity
source	Design Studies. January 1990. vol. 11: pp. 17-28 : ill. includes bibliography
summary	The incorporation of precedents into a present design situation by adaptation, restructuring and reformulation depends upon processes of typification and generalization. The function of prototypes as a characteristic form of generalized and structured knowledge in design is described. A precedent-based design model employing memory-based reasoning is proposed. It is argued that typological concepts can serve as a matching level between situation types and solution types. In such an approach both the organization of structured knowledge and the mechanisms of matching to prior knowledge such as cross-indexing and analogy appear to be of seminal importance. A memory-based reasoning process in routine, innovative and creative design is postulated. This is based on concepts of dynamic and episodic memory. Relevant work in the fields of memory organization, machine learning and analogical reasoning is considered with respect to its significance to the field of knowledge-based design

title	Using high-level constraints to aid space planning applications in computer-aided design
source	University of Toronto, Department of Computer Science
summary	This thesis describes a system that aids in solving space planning and layout design problems through an innovative use of constraints. Space planning problem solving is aided by constrained manipulation, a trial-and-error approach, and modelling the scaling properties of objects. Constraints are used to model various physical properties of solid objects (including gravity and friction) and to control the way in which objects scale. The system runs on a Silicon Graphics workstation supporting interactive, real-time, 3-dimensional graphics that aid in visualizing designs. The problems handled by our prototype are restricted to objects representable with rectangular solids oriented along the cartesian axes. This system was used by designers and novice computer users to solve a studio layout problem. Constraints were found to aid in the manipulation of objects by providing predictable behaviour for objects. The test results indicate that subjects learn the behaviour of objects easily and use this information in useful ways. In addition, there are indications that constraints can reduce users' cognitive loads at the user interface level. The coupling of constraints with the interactive, 3-dimensional aspect of the system encourages the use of the system at earlier stages of the design process than simple geometric drafting systems.

title	Classes of Design-Classes of Tools
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 77-90
summary	It is unrealistic to expect one computer-aided design tool to sufficiently support any one given design process. Yet it is necessary to define new CAD programs that give semantic support in design. To this end, the paper first differentiates phases and classes of design and then attempts to establish relations between the defined classes and appropriate computer-aided design tools. In three main sections it describes (i) routine, innovative and creative design, (ii) a set of corresponding prototype design tools, and (iii) two examples of routine and innovative design which use these tools. The purpose of the paper is to make a contribution to the definition of domain specific aspects of CAD and to propose a mapping between processes and tools.

title	An Analysis of Using a Digital 3D Sundial as a Design and Decision Support Tool
doi	https://doi.org/10.52842/conf.caadria.1996.131
source	CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 131-141
summary	The rapid speed of computer development brings new technologies, and these advances require innovative investigations to apply them optimally in the field of architecture. Burkett (1984) demonstrated that computer graphics can ‘provide an excellent opportunity for exploring solar issues in building redesign’. With one of the latest computer technologies, the "hyper-model” environment, this research investigates how to environment can become an aid in the design and decision support area. The research first reviews the communication between the architect and the client as described by Salisbury (1990). The review indicates that an interactive 3D hypermedia paradigm, with quick response, fast data manipulation and 3D visualization, offers a better communication media between the architect and the client. This research applies the "hyper-model” environment to design and develop a new methodology in collecting, analyzing, and presenting solar data. It also endeavors to show the possibilities of using the environment in design process.

title	Experiments as Modus Operandi
source	Journal of Architectural Education. November, 1990. Vol. 44: pp. 37-48 : 9 p. of ill
summary	Architecture has for too long focused on the presentation of pristine objects and the presentation in drawing form. A critical understanding of the field, however, necessitates a reevaluation of the roles of the process involved in the production of building. Rather than emphasizing surface appearances, an architecture rooted in process aims ultimately at revealing the fundamental and deep structures inherent within the making of architecture. One of the primary tasks of the process is to provoke intuition and ingenuity - and the awareness that both are founded on knowledge - and that knowledge must be applied with imagination. The experiment presented here developed sequentially with a defined structure to the process of design, moving gradually from the abstract into the concrete, thereby attempting and understanding of what Roland Barthes identified as 'concrete abstraction.'

title	A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

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	Designing with Diagrams: A Role for Computing in Design Education and Exploration
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 107-122
summary	Environmental designers, design educators and design students using computers are a constituency with a set of requirements for database structure and flexibility, for knowledge representation and inference mechanisms, and for both graphical and non-graphical operations, that are now articulatable and to-date largely unmet. This is especially so in the area called 'preliminary' or 'schematic' design, where our requirements are related to, but different from, those of our colleagues in mechanical and electrical engineering, whose needs have dominated the notable developments in this area. One manifestation of these needs is in the peculiar form of graphics called diagrams , and the ways in which environmental designers (architects, landscape architects., urban designers) use them. Our diagrams are both similar to and different from structural, circuit, or logical diagrams in important ways. These similarities and differences yield basic insights into designing and design knowledge, and provide guidance for some necessary steps in the development of the next generation of CAD systems. Diagrams as a form of knowledge representation have received little scrutiny in the literature of graphic representation and computer graphics. In the following sections I present an overview of the theoretical basis for distinguishing and using diagrams; examine some of the computational requirements for a system of computer-aided diagramming; describe a prototype implementation called CBD (Constraint Based Diagrammer) and illustrate one example of its use; and speculate on the implications and potential applications of these ideas in computer-aided design education.

source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 31-48
summary	The present paper outlines a plan for the teaching of architectural composition with computer assistance.The approach is to introduce students to a series of architectural languages characterized by a vocabulary of elements and a grammar whose rules indicate how these elements can be placed in space. Exercises with each language include the analysis of precedents; the generation of forms using a given rule set; and follow-up studies with an expanded rule set. The paper introduces languages and exercises through illustrative examples. This architectural content can be taught in the traditional way. The use of computers is motivated by expectations which are stated, and some basic requirements for the needed software are listed. Work to develop this software has started.

title	Relational Modeling: A Basis for Computer-Assisted Design

summary	Today's computer assisted design (CAD) systems automate traditional ways of working with tracing paper and pencil, but they cannot represent the rules and relationships of a design. As hardware becomes faster and memory less expensive, more sophisticated fundamental software technologies will be adopted. This shift in the basis of CAD will provide powerful capabilities and offer new ways to think about designing. Recently parametric design, a technique for describing a large class of designs with a small description in code, has become a focus of attention in architectural computing. In parametric CAD systems, design features are identified and keyed to a number of input variables. Changes in the input values result in variations of the basic design. Based on conventional software technologies, parametric design has been successfully applied in many design domains including architecture and is supported by several commercial CAD packages. A weakness of parametric techniques is the need to predetermine which properties are input parameters to be varied and which are to be derived. Relational modeling is a simple and powerful extension of parametric design that overcomes this weakness. By viewing relations as reversible rather than one-way, any set of properties can be chosen as input parameters. For example, a relational model that calculates the shadow length of a given building can also be used to calculate the building height given a desired shadow length. In exercising a relational model the designer is not limited to a pre-selected set of input variables but can explore and experiment freely with changes in all parts of the model. Co is a relational modeling environment under development on the Macintosh-II computer, and Co-Draw, a prototype CAD program based on Co. Co's relationaI engine and object-oriented database provide a powerful basis for modeling design relations. Co-Draw's interactive graphics offer a flexible medium for design exploration. Co provides tools for viewing and editing design models in various representations, including spreadsheet cards, tree and graph structures, as well as plan and elevation graphics. Co's concepts and architecture are described and the implications for design education are discussed.

summary	McIntosh, in ACADIA Newsletter Vol. 9 No. 3 pp 20-23, June 1990. This book introduces the concept of modeling objects in the computer's memory so it can be used to aide the process of their design. Modeling is defined as an hierarchical abstraction of data and operators to manipulate it, subject to semantic integrity constraints that guarantee the realizability of the designed artifact in the real world. Starting with general concepts of modeling, the book moves on to discuss the modeling of shapes (form) in two and in three dimensions. The discussion covers both topology and geometry. Next the book introduces the concept of shape transformations (translation, scaling, rotation, etc.), both in absolute and in relative terms. The book then introduces the concept of assembly modeling, and adds non-graphical attributes to the representation. It concludes with a discussion on user interface and parametrization. The book includes many examples written in Pascal that complement the theory, and can be used as a basis for building a geometric modeling engine. It also includes exercises, so it can be used as a text book for a two-semester advance course in geometric modeling

source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 103-130
summary	This paper will review current progress across the building construction industry in meeting demands for use of data integration with the 3D building model as the coordinating device in building design and development. Decades of national initiatives from NEDO (1990) to Egan (1998) have striven to encourage collaboration in first the building design team and later targetting in programmas the means to accomplish this. In its 14th year 'The User Group' has intensified efforts to persuade the industry of the benefits of associating all data involved from the first briefing and conception of design needs and ideas, through the development of the design, testing for structures, costs, heating, lighting, urban and rural environmental impact, facilities management, adaptation and even the eventual controlled demolition of the building. Examples in this paper will be reported from 'The User Group' conference, "Profit from Data Integration: An industry update", (NEC, Birmingham, Nov. 1998), to indicate how various organisations are now profiting from data integration in 3D object orientated modelling.

title	Is Design Really Social
source	International Journal of Virtual Reality, 4:1
summary	There are many who will readily agree with Mitchell's assertion that "the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process." [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants, that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided, therefore, must permit the best communication and the best social interaction. We see a danger here, a pattern being repeated which may lead us into less than useful activities. As with several (popular) architectural design or modelling systems already available, however, computer system implementations all too often are poor imitations manual systems. For example, few in the field will argue with the statement that the storage of data in layers in a computer-aided drafting system is an dispensable approach. Layers derive from manual overlay drafting technology [Stitt 1984] which was regarded as an advanced (manual) production concept at the time many software engineers were specifying CAD software designs. Early implementations of CAD systems (such as RUCAPS, GDS, Computervision) avoided such data organisation, the software engineers recognising that object-based structures are more flexible, permitting greater control of data editing and display. Layer-based systems, however, are easier to implement in software, more familiar to the user and hence easier to explain, initially easier to use but more limiting for an experienced and thoughtful user, leading in the end to a lesser quality in resultant drawings and significant problems in output control (see Richens [1990], pp. 31-40 for a detailed analysis of such features and constraints). Here then we see the design for architectural software faithfully but inappropriately following manual methods. So too is there a danger of assuming that the best social interaction is that done face-to-face, therefore all collaborative design communications environments must mimic face-to-face.

summary	PHIDIAS is a hypermedia system for supporting environmental design. It embodies a theory of design as continual alternation between two complementary activities: construction of solution form and argumentation about construction. To support these activities it implements a number of advanced hypermedia concepts. These include an applicative query language providing search by both structure and content, virtual structures, composite graphic notes, query-based graphic clustering, and 'triggered' queries which connect construction acts to relevant sections of the argumentive network. PHIDIAS constitutes a new type of integrated information environment design

summary	Concepts related to digital architecture have begun to occupy a central role in current architectural discourse. Design concepts that have been the conceptual content of this discourse are now becoming integrated into the general architectural discourse. The research reports on this process of the emergence, migration, and crystallization of a new conceptual structure over the past decade under the influence of digital design and its emerging conceptual structure. The research presented in this paper examines the emergence of new ideas in architectural thinking that are related to digital architecture since 1990 until today. In order to demonstrate this shift, we have selected a representative architectural building type that is strongly and directly influenced by the conceptual content of the cultural discourse in architecture. A museum type was selected to represent features of the expression that reflects the changes and evolution of conceptual structures that underlie digital design. The research methodology is based on a method known as “content analysis”. Content analysis in our research was de- fined as including textual material in books, book chapters, essays, articles, and historical documents. A new approach for Design Content Analysis was accomplished employing the ICF analytical framework. In order to conduct a content analysis the text was coded and was broken down into categories on a variety of theoretical design themes. Our findings demonstrate that certain expressions related to digital technology have moved up from a low level descriptive function to a significant conceptual role in formulating the design content of architectural design. In our paper we describe the research, methodology findings and contribution to the definition of the conceptual content of contemporary architectural discourse on digital architecture.

summary	The concept of a knowledge based design shell is proposed as a basis for teaching design. The significance of the concept of design shell is discussed with respect to formalization, implementation, application and operation. GPRS-a generative prototype refinement design shell-is proposed, defined and elaborated. A plan type is introduced as one significant kind of structure of knowledge in architectural design is introduced. A method for representing syntactic and the semantic content to be used in design refinement is proposed. The method exploits the characteristics of both rules and frames, and integrates them in a prototype-based design system. This is demonstrated in a system called PRODS. Finally, the significance of such an approach in teaching is discussed.
