title Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

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 Creativity in Invention and Design
source Cambridge University Press
summary In this book, creativity in technology is discussed using a computational approach. Examining an important historical episode in computer technology as a case study, namely, the invention of microprogramming by Maurice Wilkes in 1951, the author presents a plausible explanation of the process by which Wilkes may have arrived at his invention. Based on this case study, the author has also proposed some very general hypotheses concerning creativity that appear to corroborate the findings of some psychologists and historians and then suggests that creative thinking is not significantly different in nature from everyday thinking and reasoning.

title Information Systems for Spatial Data
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper describes a continuing research project aimed at the development of a prototype information system to represent and manipulate models of urban settlements. This inter-disciplinaryproject involves researchers and teachers in the fields of urban design, photogrammetry and CAD. Based upon the requirements identified by the urban design team, the photogrammetry teamused aerial imagery to produce accurate digital models of various features of urban settlements. The models comprise natural features like terrain data, water and vegetation systems, and man made features like transportation networks, land parcels, and built-up volumes. These data are represented in the three dimensions, and they are further linked with nongraphic attributes stored in an external database schemata. The architecture of the system under development has been described previously. In this paper, we focus on the generation of thematic abstractions. The working hypothesis for our current work is that (i) to enable reliable decision-making in urbandesign contexts, we require digital models that are complete and accurate at a certain degree of resolution, and (ii) during various stages in the decision-making, we need useful abstractionswhich encode only the salient information and no more. In more specific terms, we are interested in finding computational means to automatically generate schematic generalizations of data that succinctly represent some information without recomputing or displaying all the vectrs and other details. In this papar we present some of the strategies that we employ to support such operations in our system and also present graphic examples that demonstrate the potential andlimitations of our approach.

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.

title An Information Model of Energy Performance in Early Building Design
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Design is a creative and dynamic process. The level to which a future generation of Intelligent Integrated Building Design Systems will be able to support this process depends on the power of the underlying conceptual models to cover the semantics of design. In the definition of generic building models, the concept of constraints appears to be a powerful means to formalize those semantics. Both design performance goals, and rules and relations in design composition can be described as constraints. The Engineering Data Model (EDM), recently developed at UCLA, acknowledges this fact. It allows the formal definition of object oriented building models, using constraints as the central concept for describing relations. This paper will discuss the development of an EDM building model for the integrated design for energy performance, and the implementa-tion of this model in a small prototype system. We will specifically deal with modelling informati-on in the early design stages. This information typically consists of multiple global design alternatives on one hand, and a wide range of conflicting design goals on the other hand. In the paper, it is demonstrated that integration of these conflicting views on building performance in one coherent model is the key to obtaining an optimal design result. Using the Dutch building codes for energy performance (NEN 2916) as an example of design goals, the concepts and relations of these building codes were translated to a formal EDM model. A small shell was built on top of this computer-interpretable model, to demonstrate the useability of the model during the solving of a concrete design problem. It is shown that the EDM building model is able to provide the designer with integrated information through combining different sets of performance constraints and design alternatives in one environment.

title An Open Daylighting Simulation Environment
source Carnegie Mellon University, Pittsburgh
summary Various studies have shown that performance simulation tools have not been integrated effec- tively in the architectural design process. The conventional lighting simulation tools have been characterized as decision verification tools rather than design support tools. Particularly in the early design stage, when crucial and often irreversible decisions are made, this evident lack of appropriate lighting simulation environments represents a serious drawback. The "mono-directionality" of the conventional simulation tools can be identified as one of the factors responsi- ble for insufficient integration of computational lighting modeling tools in the design process. In response to this circumstance, this thesis presents the conceptual background and the proto- , typical realization of an "open" daylighting simulation environment (GESTALT) to support architectural lighting design and education. Open simulation environments aim at extension (and inversion) of the design-to-performance mapping mechanisms of the conventional build- ing performance simulation tools. Toward this end, two fully operational versions of GESTALT have been implemented. GESTALT-01 is an explicit implementation based on invertible "fast-response" computational modules. GESTALT-02 is an implicit version that uses a comprehensive computational daylight simulator and investigative projection technique for performance-driven design exploration. Concepts, implementations, case studies, contributions and future directions are presented.

title Communicative Acts in Cooperative Architectural Design Environments
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The purpose of this paper is to present a scheme, that can be used to support the communication process in cooperative design. Computational aids for design have largely been for a designerworking by himself/herself. These aids have also been supplemented by the widespread use of artificial intelligence approaches. However, design is so complex, and very rarely acted upon by a single designer but many more working towards the same aim. This involves a new paradigm in which designers need to cooperate with each other using a computational medium. A protocol analysis in cooperative design has been carried out and technological support has been proposed.Cooperative design becomes an important paradigm for the next generation of intelligent computer aided design systems. It will be conducted in many forms among several designers and willrequire the support of advanced communication facilities beyond the "passive" transmission of data and messages. Technological advances in communication networks have opened up new ways for cooperative design interaction across several processes of cooperation among designers, designers and computer aided design systems, computer aided design systems and knowledge based systems, and knowledge based systems themselves. In cooperative design environments, aunit of communication among designers is the transfer of a message from one designer (a sender) to another (a receiver). The aim of such communication is to provide the receiver with some information or to have the receiver take certain actions. Inspired by the speech act theory, a branch of the philosophy of language and linguistics, such a unit is called a communicative act. By analogy to architectural design, a communicative act is a performing act in designers communication.

summary The process of architectural design aims to define a physical form that will achieve certain functional and behavioral objectives in a particular context. It comprises three distinct, but highly interrelated, operations: (1) Definition of the desired objectives; (2) production of alternative design solutions; (3) evaluation of the expected performances of the solutions and their comparison to the predefined objectives. Design can be viewed as a process of search for a solution that satisfies stated needs, while at the same time adapting the needs to the opportunities and limitations inherent in the emerging solution. // Computational techniques were developed to assist each one of the three operations, with varying degrees of success. We propose to integrate all three operations into one whole, by developing a computational model that will facilitate smooth transition from one operation to another. The role of computers in supporting this model will include providing a knowledge base of prototypical design objectives and solutions, storing project-specific design goals and solutions, and predicting their expected performances. This paper discusses the rationale and background for developing such a knowledge-based design system, and presents the parameters for implementing it as a computational tool to support architectural design. Examples from a prototype implementation serve to illustrate the discussion.

summary The Semantic Modeling Extension (SME) prototype implements a unique approach to integrated architectural CAD that places the drawing act first in the design process. After drawing a design idea using a computer graphic system, the designer interprets the design, providing semantic content to the graphic entities. An interpretation expresses the meaning of the design with respect to a particular issue, such as structural sufficiency, energy consumption, or requirements for egress, and provides reasoning to evaluate the design addressing that issue. A design may have many interpretations to express the multiple issues that are relevant in a design project. The designer may add or delete interpretations of the design as issues change during the course of the project. Underlying the SME prototype are the concepts of form, function and behavior. In the prototype, evaluation of a design is done by deriving behavior from the graphically represented forms and relating the behavior to stated functions or requirements. The concepts of interpretations and form, function and behavior together establish a virtual product model for design. In contrast to component based approaches to product modeling that tightly bind form representations to their behavior and function, a virtual product model allows the designer to manipulate the relations among these three descriptors of a design, and thus manipulate the semantics of the design entities. By distinguishing between the act of proposing a design by drawing the conceived form and the act of assigning meaning to the form, the virtual product model approach supports both graphic thinking for design synthesis and symbolic reasoning for design evaluation. This paper presents a scenario of the use of the SME prototype in building design; provides an analysis of the design process and computational support described in the scenario; contrasts a virtual product model approach with a component-oriented product model approach; describes the software implementation of SME; and presents implications and conclusions regarding design process and technical integration.

title Solving design problems by computational exploration
source J. S. Gero and E. Tyugu (eds), Formal Design Methods for CAD, NorthHolland, Amsterdam, pp. 249-270
summary Most real-world problems, especially design problems, are ill-structured, but formal approaches to problem-solving in AI have only really made progress into techniques for solving well-structured problems. Nevertheless, such research contains clues which illuminate the way towards formal approaches to solving ill-structured problems. This paper presents the foundations of an approach towards developing a better computational understanding of ill-structured problems and how to solve them computationally, with the eventual aim of giving AI problems a much greater and more useful role in the design process. The main issues which come up in this endeavour are the notions of different kinds of ill-structuredness, and the meaning of a 'solution' to an ill-structured (and hence possibly insoluble) problem. Some basic algorithmic recipes are proposed for dealing with the main kinds of ill-structuredness, and the initial design of a general computational technique which deals with general ill-structuredness is discussed.

summary Computational support in the domain of building design is hampered by the need to control generation and search processes both of which are elusive due to the lack of strong domain theories. Case based reasoning paradigm may be useful to overcome some of these difficulties. A case based design system is presented here that enables case adaptation and case combination of design cases to generate new design solutions more efficiently. Some issues in our approach that are different from other projects with similar aims are also discussed.

title On visual design thinking: the via kids of architecture
source Design Studies 15 (2), pp. 158-174
summary Designers invariably use imagery to generate new form combinations which they represent through sketching. But they also do the reverse: they sketch to generate images of forms in their minds. Common belief regards such activity as non-rational. In contrast, we assert that interactive imagery through sketching is a rational mode of reasoning, characterized by systematic exchanges between conceptual and figural arguments. Cognitive science, strongly dominated by a linguistic paradigm, has yet to recognize the paramount role of visual reasoning in many instances of problem solving; and in design tool-making, computational and otherwise, we must learn to optimize rather than bypass intuitive visuality.

This article reviews these roles and presents a case study of computing at the College of Architecture and Planning (formerly Environmental Design) at the University of Colorado at Boulder. Three categories of instruction make up the curriculum: Tool-using courses teach specific applications, tool-building courses focus on developing new design software, and design theory and methods courses provide rationale for specific computational approaches. Finally, strategies employed in developing this curriculum are discussed.

summary The paper describes recent explorations in sketch recognition and management to support architectural design. The exploration and decisionmaking of early, conceptual design is better suited to freehand drawing, sketching, and diagramming than to the hard-line drawing and construction kit approaches of traditional CAD. However, current sketch programs that simulate paper and pencil fail to take advantage of symbolic manipulation and interactive editing offered by computational environments. The paper presents a computer as cocktail napkin' program, which recognizes and interprets hand-drawn diagrams and provides a graphical search facility, simulated tracing paper, and a multi-user shared drawing surface. The cocktail napkin is the basis of Stretch-A-Sketch, a constraint-based draw program that maintains spatial relations initially specified by a diagram. The cocktail napkin program is also the basis for a query-by-diagram scheme to access a case-based design aid as well as a small collection of images of famous buildings. The paper briefly reviews these extensions of the cocktail napkin program.

summary Idea association involves a dynamic linking process among ideas, cases and the links themselves. Based on the knowledge representation issue-concept-form proposed by Oxman (1994), design ideas, cases and links are elucidated. Furthermore, various and dynamic linking plays are involved in two steps: divergent, in which alternative idea entities are linked, and convergent, in which these idea entities are selected. These linking plays provide a computational mechanism for indexing prior design cases dynamically. Finally, an index prototype for supporting the linking process of idea association, called Mapmaker, is proposed in this paper.

title Intuitive Analysis as Mediator Between Concept and Representation
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Representation in Computer Aided Architectural Design Systems has to date largely focused on the presentation of the end product of design activity, namely the ultimate built form. In thisrespect, 3-dimensional representations traditionally associated with CAAD visualization have relied heavily upon verisimilitude for their efficacy, and have therefore necessitated high levels of dimensional accuracy together with exhaustive description, both of which are absent in the early stages of design formulation. This paper investigates the desired structure of a computational design formulation system which is based, not upon the representation (or presentation) of ultimate form, but instead upon the representation of architectonic ideas resident in the designer's mind, which are central to the organization and generation of proposals. These ideas are of two kinds: conceptual generators, both poetic and architectonic, and the organizational parti or schematic proposals, which embody them. The representation of ideas rather than end form has two primaryobjectives. Firstly, it enables the designer's realization and clarification of concept or parti, and secondly, but most importantly, it enables the designer to critically assess these ideas in relation tothe contextual situation and brief. The computational representation must be structured in a manner which supports the designer's intuitive critical assessment of it, to in turn induce a modification and development of the initial design ideas. Repeated transformation, representation, and intuitive analysis, can then continue in a cyclical manner until an end proposal is achieved. Intuitive analysis, which becomes the mediator between idea and representation, is itself computationally supported by the dual methodologies of comparative and modal superimposition. Superimposition of previous with present representation (either in two or three dimensions)enhances comparative assessment of design developments. Modal analysis, on the other hand, facilitates the superimposition of schematic representations of modes of design thought (circulationpattern with volumetric arrangement, say) in order to intuitively assess their interaction or conflict.

title Unsupervised Dynamic Concurrent Computer-Aided Design Assistant
source Los Angeles: UCLA
summary The increasing capability of computer-aided architectural design systems has strengthened the role that the computer plays in the workplace. Due to the complexity of developing new techniques and research, these systems are undertaken mostly by scientists and engineers without significant architectural input (Willey, 1991). The design concept of these systems may be based on a well-defined and well-understood process, which is not yet realized in architectural design (Galle, 1994). The output of such research may not be easily adapted into the design process. Most of the techniques assume a complete understanding of the design space (Gero and Maher, 1987) (Willey, 1991). The description or construction of the design space is always time and space consuming, and the result can never be complete due to the ever-changing nature of architectural design. This research intends to initiate a solution for the above problems. The proposed system is an unsupervised-dynamic-concurrent-computer-aided-design assistant. The “unsupervised” means the learning process is not supervised by the user because it is against the designer's nature to “think-aloud” in the design studio and it also increases the work load. It is dynamic because the size of the knowledge base is constantly changing. Concurrent means that there are multiple procedures active simultaneously. This research focuses on learning the operational knowledge from an individual designer and reapplying it in future designs. A computer system for this experiment is constructed. It is capable of The preliminary result shows a positive feedback from test subjects. The purpose of this research is to suggest a potent computational frame within which future developments may flourish.

title Precedents in design: a computational model for the organization of precedent knowledge
source Design Studies, Vol. 15 No. 2
summary A computational model for the organization of design precedent knowledge is developed. The model is composed of distinct chunks of knowledge called design stories. A formalism for the design story is proposed which represents the linkage between design issue, concept and form in designs. Stories are structured in memory according to a semantic network. The lexicon of the semantic network acts as a memory index. The memory structure and indexing system are demonstrated to enhance search and to support cross-contextual browsing and exploration in the precedent library. The approach is demonstrated in a pilot design aid system in the task domain of early conceptual design in architecture.

title Design Education in the Virtual Studio
doi https://doi.org/10.52842/conf.ecaade.1994.152
source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, pp. 152-160
summary The paper presents an approach to the re-orientation of computational studies in support of the didactic role of the design education program. A definition of computational design studies is proposed which identifies the transfer of explicit design knowledge as one of the functions of this academic field. The concept of design knowledge modeling is introduced as an important component of the knowledge formulation role of computational design studies. A current project is discussed which employs knowledge modeling in a VR system to develop an interactive design environment.
