summary Design is the computation of shape information that is needed to guide fabrication or construction of an artifact. This information normally specifies artifact topology (connections of vertices, edges, surfaces, and closed volumes), dimensions, angles, and tolerances on dimensions and angles. There may also be associations of symbols with subshapes to specify material and other such properties. The process of design takes different forms in different contexts, but the most usual computational operations are transformations (unary operations) and combinations (binary operations) of shapes in a two-dimensional drawing or a three-dimensional geometric model. An initial vocabulary of shapes, together with a repertoire of shape transformation and combination operators., establishes the shape algebra within which the computation takes place. The computation terminates successfully when it can be shown that certain predicates are satisfied by a shape produced by recursively applying the transformation and combination operators to the initial vocabulary. These predicates are usually stated in symbolic (verbal or numerical) form. Thus determination of whether a predicate is satisfied usually involves producing a numerical or verbal interpretation of a drawing, then deriving inferences from this interpretation by applying rules or formulae.

title Color Contrast and CAAD: The Seven Color Contrasts of Johannes Itten

summary Computer-aided architectural design is design with color - the monitor of a CAAD system is a display of color, a place where images are produced by color manipulation. The success of these images can be judged by the ability of the colors selected to communicate graphic ideas and to convey graphic information. Color as a visual phenomena intrigued the impressionist painters at the end of the nineteenth century; it was the focus of much attention at the Bauhaus in Weimar Germany. When Johannes Itten was appointed as a Master of Form at the Bauhaus in 1919, he developed "an aesthetic color theory originating in the experience and intuition of a painter". In his definitive work, Itten postulates seven ways to communicate visual information with color. "Each is unique in character and artistic value, in visual, expressive and symbolic effect, and together they constitute the fundamental resource of color design". These seven contrasts provide a lexicon of the methods by which computer images convey graphic information. The colors which form a computer image can be simply manipulated to illustrate these contrasts; today's computers make color manipulation a very simple matter. This paper is composed of short essays about each of these contrasts and how they can guide the selection of appropriate colors to convey visual intent on a picture tube. Considered together the contrasts of Itten provide a fundamental resource for electronic graphic communication.

summary This paper is not just about the future of computerized design practice. It is about what to do today in contemplation of tomorrow-the issues of computercentered practice and the courses of action open to us can be discerned by the careful observer. The realities of computerized design practice are different from the issues on which design education still fixes its attention. To educators, the present paper recommends further clinical research on computerized design firms and suggests that case studies on the matter be developed and utilized as teaching material. Research conducted by the author of this paper indicates that a new form of design firm is emerging-the computerized design firm-totally supported and augmented by the new information technology. The present paper proceeds by introducing an abridged case study of an actual totally electronic, computerized design practice. Then, the paper concentrates on modelling the computerized design firm as an intelligent system, indicating non-trivial changes in its structure and strategy brought about by the introduction of the new information technology into its operations - among other considerations, different strategies and diverse conceptions of management and workgroup roles are highlighted. In particular, this paper points out that these structural and strategic changes reflect back on the technology of information with pressures to redirect present emphasis on the individual designer, working alone in an isolated workstation, to a more realistic conception of the designer as a member of an electronic workgroup. Finally, the paper underlines that this non-trivial conception demands that new hardware and software be developed to meet the needs of the electronic workgroup - which raises issues of human-machine interface. Further, it raises the key issues of how to represent and expose knowledge to users in intelligent information - sharing systems, designed to include not only good user interfaces for supporting problem-solving activities of individuals, but also good organizational interfaces for supporting the problem-solving activities of groups. The paper closes by charting promising directions for further research and with a few remarks about the computerized design firm's (near) future.

title A digital Procedure of Building Construction: A practical project

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 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 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.

summary This paper will present prototypical software being used in the teaching of urban design to students and for use by professionals in the early stages of a project. The system is intended to support a heuristic approach to design. That is, it supports a process of refining ideas and understandings through a process of trial and error. The support or aid to design comes in the form of a didactic real-time programme. Its power lies in its ability to provide instantaneous response to operations on the data that can allow one to develop three-dimensional spatial ideas in an intuitively driven manner. This condition appears to occur for both novice and expert computer operators.

The presentation will present our experience to-date in using conventional computer graphic tools to represent design ideas and contrast it with a video demonstration of ow prototypical dynamic urban design modelling software for the Silicon Graphics IRIS computers.

summary The initial purposes of this work were to build a 3D model of the old city of Messina and to reconstruct a walk through it; to understand the "Ghost city," the parts that form it, and the rules of its plan, which are explicit in some cases but hidden most of the time; to measure its space, appreciate the similarities to and differences from modern city plans, and use the information to improve the plans of tomorrow. It might seem a useless study of a nonexistent city, and yet during the months of detailed work, of patient reconstruction from the surveys and photographs of the city destroyed in 1908, we began to consider how it was still possible to obtain spatial values of and to project behaviors in the lost city, in other words, to practice tests on memory that are very interesting for people working in a context in which memory no longer exists. The work presented here is the first stage of a more complex research project still to be carried out on Messina as it was at the end of the nineteenth century. Here we constructed a 3D model of some parts of the city prior to the earthquake of 1908 and made a five-minute video, using cartoon techniques, of an "impossible" walk through the city. The fragments of the city were reconstructed from available documentary sources, primarily photographic images, which tended to be of the most important places in the city.

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.

title The structure and function of diagrams in environmental design :a computational inquiry
source Massachusetts Institute of Technology
summary The design process often begins with a graphical description of the proposed device or system and sketching is the physical expression of the design engineer's thinking process. Computer Aided Design is a technique in which man and machine are blended into a problem solving team, intimately coupling the best characteristics of each. Solid modelling is developed to act as the common medium between man and the computer. At present it is achieved mainly by designing with volumes and hence does not leave much room for sketching input, the traditional physical expression of the thinking process of the design engineer. This thesis describes a method of accepting isometric free hand sketching as the input to a solid model. The design engineer is allowed to make a sketch on top of a digitizer indicating (i) visible lines; (ii) hidden lines; (iii) construction lines; (iv) centre lines; (v) erased lines; and (vi) redundant lines as the input. The computer then processes this sketch by identifying the line segments, fitting the best possible lines, removing the erased lines, ignoring the redundant lines and finally merging the hidden lines and visible lines to form the lines in the solid in an interactive manner. The program then uses these lines and the information about the three dimensional origin of the object and produces three dimensional information such as the faces, loops, holes, rings, edges and vertices which are sufficient to build a solid model. This is achieved in the following manner. The points in the sketch are first written into a file. The computer than reads this file, breaks the group of points into sub-groups belonging to individual line segments, fits the best lines and identify the vertices in two dimensions. These improved lines in two dimensions are then merged to form the lines and vertices in the solid. These lines are then used together with the three dimensional origin (or any other point) to produce the wireframe model in three dimensions. The loops in the wireframe models are then identified and surface equations are fitted to these loops. Finally all the necessary inputs to build a B-rep solid model are produced.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

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

The review process is supported by an in depth survey of students experiences both prior to and during the course. With a large number of students enrolled in the course (158) the findings from this survey can be seen to offer a statistical reliability which is in contrast to the more usual anecdotal approach.

summary This is a period of relative detente among academics in the field of computers and architecture, advocating the use of computers in a design studio is today received more politely than, as in the past, when it was received like a declaration of war. Among some research groups at M.I.T. and Harvard to first engage In this field, the approaches were so dissimilar to one another that they could be considered as constituting separate schools of thought. Over time, however, a number of paths have led to a similar direction, if not agreement among principal investigators. The lack of sharply competing ideologies today may be a little less exciting: however, the enormous growth of the academic discipline seems now to allow for a fruitful exchange of ideas between positions that no longer seem mutually exclusive.

Two views are important, among others, at M.I.T. and Harvard. The classic M.I.T. view looks upon the AI Lab as a microcosm for examining how architects think. Underlying this view is the position of 'lets examine the way architects think about design and build tools which can reflect that process'. Another point of view, as expressed at Harvard, is speculative on what architects seem to do in design practice and education, rather than speculative on the nature of thinking per se. Both views seem ultimately to be concerned with representing architectural design knowledge within computers. And in the rob of computers as a design medium. This paper examines how the M.I.T. view and the Harvard view have superficially been associated with separate research directions. As these contrasting points of view incorporate many common themes. The author finds that it may be possible to take an eclectic position in teaching computer aided design.

title Supporting Reflection-in-Action in the Janus Design Environment

summary We have developed a computer-based design aid called Janus, which is based on a model of computer-supported design that we think has significance for the future of architectural education. Janus utilizes a knowledge-based approach to link a graphic construction system to hypertext. This allows the computer to make useful comments on the solutions that students construct in a CAD-like environment. These comments contain information intended to make students think more carefully about what they are doing while they are doing it. In other words, Janus promotes what Donald Schon has called "reflection-inaction" (Schon, 1983). The Janus design environment is named for the Roman god with a pair of faces looking in opposite directions. In our case the faces correspond to complementary design activities we call construction and argumentation. Construction is the activity of graphically creating the form of the solution e.g., a building. Traditionally this has been done with tracing paper, pencils, and pens. Argumentation is the activity of reasoning about the problem and its solution. This includes such things as considering what to do next, what alternative courses of action are available, and which course of action to choose. Argumentation is mostly verbal but partly graphical.

title The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [Conference Proceedings]

summary Design is the computation of shape information that is needed to guide fabrication or construction of artifacts. But it is not so straightforward as, say, the computation of numerical information required to balance a checkbook. This is partly because algebras of shapes are not as well understood and precisely formalized as algebras of numbers, partly because the rules for carrying out shape computations tend to be fluid and ill defined and partly because the predicates that must be satisfied to achieve successful termination are often complex and difficult to specify. For centuries architects have carried out shape computations by hand, using informal procedures and the simplest of tools. Over the last two decades though, they have made increasing use of more formal procedures executed by computers. It is still too early to be sure of the gains and losses that follow from this development, but there is no doubt that it raises some challenging questions of architectural theory and some perplexing issues for those concerned with the future of architectural education. This book frames those issues and provides a diversity of perspectives on them. Its contents were initially presented at the CAAD Futures 89 Conference-an international gathering of researchers and teachers in the field of computer-aided architectural design which was jointly sponsored by the Harvard Graduate School of Design and the MIT Department of Architecture and held in Cambridge, Massachusetts, in July 1989. There are four major sections: Theoretical Foundations, Knowledge-Based Design Tools, Information Delivery Systems, and Case Studies: Electronic Media in the Design Studio. In a representative collection of current views, over thirty extensively illustrated papers discuss the experiences of universities in the USA, Europe, Japan, Israel, Canada, and Australia, articulate present theoretical and practical concerns, provide criticism of media and methods, and suggest directions for the future. Architectural educators and architects concerned with the effect of computer technology on the design process will find here an indispensable reference and a rich source of ideas. This book was itself prepared in an electronic design studio. Composition and typography, most image collection and placement, and such editing as was practical within this publishing format, were all performed digitally using Macintosh computers at the Harvard Graduate School of Design during a period of a few weeks in 1989.

title Form Processing Workshop: Architectural Design and Solid Modeling at MIT
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. 441-455
summary Computing impacts the preliminary architectural design process as a tool for observation and analysis, as a formal prototyping tool, and as a vehicle to generate variations of objects and assemblies. Through the use of both traditional and computing tools, the Form Processing Workshop examines the relationship between design decisions and design tools. The Workshop utilizes several software applications, with emphasis on the use of a solid modeler. This curriculum was developed with the support of MIT's Project Athena.

title Shape Recognition and Transformation: A Script-Based Approach
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. 149-170
summary Design evolves. Architects deploy considerable knowledge to develop their designs from one stage to the next. Drawings play a major role in describing the 11 state" of design at each stage; however, they do not explicitly reveal the knowledge used to achieve the design, for the knowledge is concealed in the "process" between these stages rather than in the drawings themselves. This process involves parametric and schematic transformations as well as perception of unanticipated possibilities emerging from the drawings in progress. To make an impact on design, CAD must address these issues of design knowledge, but so far its focus has been instead on drawings as relatively static collections of graphic primitives. This paper introduces the concepts of shapes and shape transformation as fundamental aspects of design knowledge. It is implemented on a computer program in the form of a prototype shape-scripting language. In summary, this language works as a shell to encode a set of shape categories and their transformations, and it enables progressive shape recognition and shape transformation in line drawings. An appropriate set of these encoded transformations may represent a body of syntactic knowledge about an architectural style. This opens up the exciting possibility of a computational implementation of a shape grammar.

title Typological Knowledge in Computer-Aided Housing Design -- Chapter 6
source Helsinki, Finland: the Finish Academy of Technology, 1989. No. 92: pp. 49-60 : ill. includes bibliography
summary This paper considers logical aspects in the knowledge and rule based approach to housing planning and design. The generation problem in housing design is formulated and some experimental work in the field is discussed. Logical methods in knowledge-based generation are introduced as a frame for various production situation. Formation of typical compositions is discussed as a basis for more advanced design. Generation of typological classes and mastering of individual solutions by means of sets of predicates are used to form knowledge-bases for elementary housing solutions. The possibilities of sentenial calculi are characterized in order to allow reconstruction of tradition-guided expert know how. Finally some desirable characteristics of computer aided housing design systems are illustrated
