summary	Creative processes in computer-aided design are identified as those that introduce new design variables into the design process. This paper describes the ideas behind the development of a computational model of creative processes in design. This computational model is founded on the use of mutation and analogy processes working in tandem using design prototypes as the representation scheme

summary	Design can be considered a process leading to the definition of a physical form that achieves a certain predefined set of objectives. The process comprises three distinct operations: (1) definition of the desired set of performance criteria (design goals); (2) production of alternative design solutions; (3) evaluation of the expected performances of alternative design solutions, and comparing them to predefined criteria. Difficulties arise in performing each one of the three operations, as well as in combining them into a purposeful, unified process. First, it is difficult to define the desired performance criteria prior to and independently of, the search for an acceptable solution that achieves them, since many aspects of the desired criteria can only be discovered through the search for an acceptable solution. Furthermore, the search for such a solution may well alter the definition of these criteria, as new criteria and incompatibilities between existing criteria are discovered. Second the generation of a design solution is a task demanding creativity, judgement, and experience, all three of which are difficult to define, teach, and otherwise capture in some explicit manner. Third, it is difficult to evaluate the expected performances of alternative design solutions and to compare them to the predefined criteria. Design parameters interact with each other in complex ways, which cause effects and side effects. Predicting the expected performances of even primary effects involves extrapolating non-physical characteristics from the proposed solution's physical organization, a process which relies on a host of assumptions (physical, sociological, psychological, etc.) and hence is seldom a reliable measure. A fourth problem arises from the need to coordinate the three operations in an iterative process that will converge on an acceptable design solution in reasonable time. Computational techniques that were developed in the past to assist designers in performing the above mentioned activities have shown limitations and proved inadequate to a large degree. In this paper we discuss the work in progress aimed at developing an intelligent support system for building and architectural design, which will be able to play a decisive role in the definition, evaluation and putting into effect of the design choices.

title	Analogical and inductive reasoning in architectural design computation
source	Swiss Federal Institute of Technology, ETH Zurich
summary	Computer-aided architectural design technology is now a crucial tool of modern architecture, from the viewpoint of higher productivity and better products. As technologies advance, the amount of information and knowledge that designers can apply to a project is constantly increasing. This requires development of more advanced knowledge acquisition technology to achieve higher functionality, flexibility, and efficient performance of the knowledge-based design systems in architecture. Human designers do not solve design problems from scratch, they utilize previous problem solving episodes for similar design problems as a basis for developmental decision making. This observation leads to the starting point of this research: First, we can utilize past experience to solve a new problem by detecting the similarities between the past problem and the new problem. Second, we can identify constraints and general rules implied by those similarities and the similar parts of similar situations. That is, by applying analogical and inductive reasoning we can advance the problem solving process.The main objective of this research is to establish the theory that (1) design process can be viewed as a learning process, (2) design innovation involves analogical and inductive reasoning, and (3) learning from a designer's previous design cases is necessary for the development of the next generation in a knowledge-based design system. This thesis draws upon results from several disciplines, including knowledge representation and machine learning in artificial intelligence, and knowledge acquisition in knowledge engineering, to investigate a potential design environment for future developments in computer-aided architectural design. This thesis contains three parts which correspond to the different steps of this research. Part I, discusses three different ways - problem solving, learning and creativity - of generating new thoughts based on old ones. In Part II, the problem statement of the thesis is made and a conceptual model of analogical and inductive reasoning in design is proposed. In Part III, three different methods of building design systems for solving an architectural design problem are compared rule-based, example-based, and case-based. Finally, conclusions are made based on the current implementation of the work, and possible future extensions of this research are described. It reveals new approaches for knowledge acquisition, machine learning, and knowledge-based design systems in architecture.

title	The Combination of Design Media and Design Creativity _ Conventional and Digital Media
doi	https://doi.org/10.52842/conf.caadria.2007.x.w5x
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Creativity is always interested in many fields, in particular, creativity and design creativity have many interpretations (Boden, 1991; Gero and Maher, 1992, 1993; Kim, 1990; Sternberg, 1988; Weisberg, 1986). In early conceptual design process, designers used large number of sketches and drawings (Purcell and Gero, 1998). The sketch can inspire the designer to increase the creativity of the designer’s creations(Schenk, 1991; Goldschmidt, 1994; Suwa and Tversky, 1997). The freehand sketches by conventional media have been believed to play important roles in processes of the creative design thinking(Goldschmidt, 1991; Schon and Wiggins, 1992; Goel, 1995; Suwa et al., 2000; Verstijnen et al., 1998; Elsas van and Vergeest, 1998). Recently, there are many researches on inspiration of the design creativity by digital media(Liu, 2001; Sasada, 1999). The digital media have been used to apply the creative activities and that caused the occurrenssce of unexpected discovery in early design processes(Gero and Maher, 1993; Mitchell, 1993; Schmitt, 1994; Gero, 1996, 2000; Coyne and Subrahmanian, 1993; Boden, 1998; Huang, 2001; Chen, 2001; Manolya et al. 1998; Verstijinen et al., 1998; Lynn, 2001). In addition, there are many applications by combination of conventional and digital media in the sketches conceptual process. However, previous works only discussed that the individual media were related to the design creativity. The cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent.

title	Computational Modalities of Evaluation and Prediction in Design
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 271-284
summary	Evaluation can be defined as measuring the fit between achieved (or expected) performances and stated criteria. It is complicated by the multi-criteria and multi-level modalities of design, where an overall balance of performances is preferred to maximizing the performance of a few characteristics, and where evaluation must be performed at different design phases, each characterized by a different informational profile. Each design modality requires a different approach to evaluation: the Multi-Criteria modality requires evaluation of a proposed solution at a particular design phase from multiple points of view, while the Multi-Level modality requires the evaluation of a particular performance characteristic at several different design phases. This paper discusses the multi-modal nature of evaluation and prediction in design, exemplified by some of the approaches that have been proposed to support them computationally. It then argues for the need to develop an integrated, multi-modal design evaluation paradigm.

summary	Open Design Environment (ODE), the concept of which was proposed in 1991, is a platform on computers to support synthetic to proceed design. We have applied ODE in practical use of design, design review and presentation to make collaboration by using CG in design participants. Recent linkage between LAN and Wide Area Network, just as the Internet, gave ODE a new progress to make wide area collaboration. It leads to generate the concept of Network ODE (NODE). However, we have found some problems on system to proceed the wide area collaboration by using ODE’s Design Tools. Since they are developed on the specific computer system, they can not correspond to the wide area collaboration on various network environments. As a result, the re-arrangement of design environment and the development of Design Tools are needed, which are rather flexible and general purpose, i.e. independent of machine sort and network adaptive. In this paper, to proceed collaboration in a designer group, how to create the system of NODE is demonstrated with the new Key Technologies of network and CG.

title	Is Design Really Social
source	Creative Collaboration in Virtual Communities 1997, ed. A. Cicognani. VC'97. Sydney: Key Centre of Design Computing, Department of Architectural and Design Science, University of Sydney, 8 p.
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 think it essential to examine the foundations and assumptions on which software and environments are designed to support collaborative design communication. Of particular interest to us in this paper is the assumption about the “social” nature of design. Early research in computer-assisted design collaborations has jumped immediately into conclusions about communicative models which lead to high-bandwidth video connections as the preferred channel of collaboration. The unstated assumption is that computer-supported design environments are not adequate until they replicate in full the sensation of being physically present in the same space as the other participants (you are not there until you are really there). It is assumed that the real social process of design must include all the signals used to establish and facilitate face-to-face communication; including gestures; body language and all outputs of drawing (e.g. Tang [1991]). In our specification of systems for virtual design communities; are we about to fall into the same traps as drafting systems did?

title	Frictions and Frustrations in Creative-Informatory Work with Computer Aided Design -- CAD-Systems -- Congress I: Work with Terminals: HEALTH ASPECTS: WORKLOAD, STRESS AND STRAIN AND IRREGULAR WORKING HOURS; Causes and Measures of Stress
source	Proceedings of the Fourth International Conference on Human-Computer Interaction 1991 v.1 pp. 175-179
summary	The effects of computer aided design work on the design process are analysed by field experiments. The study focuses on the influence of 3 different design tasks (standard tasks) and 11 CAD-systems (2D and 3D), taking into account the performance and strain measurements of 43 subjects (15 design engineers, 8 technicians, 17 draughtsmen, 3 trainees). The 3 standard tasks differ in performance measurements, especially in time spent on task, quantity of generated elements, not in the quality of the solution. The kind of CAD-system influences the time spent on task as well as the design performance, with significant differences of up to 100%. The same tendency can be diagnosed in a comparison of 2D and 3D systems. During the use of different functions of the CAD-system, strain effects are identified by cross-correlation with continuously measured physiological parameters, even with CAD-functions which should reduce stresses of routine work. Deficits and complications in the handling of CAD-systems increase with the complexity of the system and thus cause an antinome effect on performance and strain of its operators: creativity is reduced by frictions and frustrations in system handling even if operators are highly trained.

title	Design process and knowledge possibilities and limitations of computer-aided design
source	University of California, Berkeley
summary	An attempt to determine how computers can be used to assist designers resulted in the development of a design theory, according to which design is 'feeling and thinking while acting.' Design is theorized as living through one's imagination, however being continuously affected by real life itself. The design process is decomposed into elementary activities that are characterized with respect to the nature of knowledge requirements and the degree to which they can be specified and delegated to computers. The results are considered as criteria to determine possibilities and limitations of computer-aided design. An integration of a variety of computer applications tools is proposed towards the design and development of a computer-based Design Support Environment (DSE), that is applicable to any design domain. The proposed DSE automates all specifiable and delegable design activities, while assisting with the nondelegable ones through appropriate user interface. A DSE demonstration prototype is also presented in the Appendix. This prototype addresses the design of fenestration and electric lighting systems of office spaces with respect to comfort, energy and cost.

title	Case-based Representation and Adaptation in Design
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 301-312
summary	By attempting to model the raw memory of experts, case-based reasoning is distinguished from traditional expert systems, which compile experts' knowledge into rules before new problems are given. A case-based reasoning system processes new problems with the most similar prior experiences available, and adapts the prior solutions to solve new problems. Case-based representation, of design knowledge utilizes the desirable features of the selected case as syntax rules to adapt the case to a new context. As a central issue of the paper, three types of adaptation aimed at topological modifications are described. The first type - casebased search - can be viewed as a localized search process. It follows the syntactical structure of the case to search for variations which provide the required functionality. Regarding the complexity of computation, it is recognized that when a context sensitive grammar is used to describe the desirable features, the search process become intractable. The second type of adaptation can be viewed as a process of self-organization, in which context-sensitive grammars play an essential role. Evaluations have to be simulated by local interaction among design primitives. The third type is called direct transduction. A case is translated directly to another structure according to its syntax by some translation functions. A direct transduction is not necessarily a composition of design operators and thus, a crosscontextual mapping is possible. As a perspective use of these adaptation methods, a CAD system which provides designers with the ability to modify the syntactical structure of a group of design elements, according to some concerned semantics, would support designers better than current CAD systems.

source	Experiences with CAAD in Education and Practice [eCAADe Conference Proceedings] Munich (Germany) 17-19 October 1991
summary	In February 1990 the University of Kaiserslautern founded the new teaching and research department "Computer-Aided Design and Construction in Environmental Planning and Architecture". Unlike other German universities, the speciality of the new teaching department is in the common education of architects and environmental planners (including urban planning), so that a wide range of computer systems is at their disposal: computer-aided architectural design systems just as geographic information systems, picture processing or information systems to support urban planning etc. No other German university disposes of this kind of common education in a single teaching department. The following aspects will be discussed: (-) The general concept of education in three dimensions, viz. a dimension of application concerning architecture and urban planning, a dimension of technical features concerning computer applications and a dimension of critical judgement. (-) Contents of education and teaching concept including examples and students' resonance. (-) Research fields in urban planning and architecture which are necessary for a practical-oriented education concept. (-) Experience with the educational background furnished by the students of architecture and environmental planning and general consequences for the teaching concept.

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 169-177
summary	Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 549-566
summary	This paper focuses on the visualization of historical architecture. The application of new Computer-Aided- Architectural-Design techniques for visualization on micro computers provides a technique for reconstructing and analyzing architectural objects from the past. The pilot project describes a case study in which the historical transformation of a town will be analyzed by using three- dimensional CAD models in combination with bitmap textures. The transformation of the historic town will be visualized in a space-time computer model in which bitmap textures enable us to display complex and relatively large architectural objects in detail. This three-dimensional descriptive model allows us to survey and analyze the history of architecture in its reconstructed context. It also provides a medium for researching the dynamics of urban management, since new combinations and arrangements with the individual architectural objects can be created. In this way, a new synthesis of the graphic material can reveal typologies and the architectural ordering system of a town.

summary	To begin with, I would like to say a few words about the problem of alienation of modern technologies which we also inevitably faced while starting teaching CAD at our department. Quite often nowadays a technology becomes a fetish as a result of lack of clear goals in human mind. There are multiple technologies without sense of purpose which turned into pure experiments. There is always the danger of losing purposeness and drifting toward alienation. The cause of the danger lies in forgetting about original goals while mastering and developing the technology. Eventually the original idea is ignored and a great gap appears between technical factors and creativity. We had the danger of alienation in mind when preparing the CAAD curriculum. Trying to avoid the tension between technical and creative elements we agreed not to introduce CAD too soon then the fourth year of studies and continue it for two semesters. One thing was clear - we should not teach the technique of CAD but how to design using a computer as a medium. Then we specified projects. The first was called "The bathroom I dream of" and meant to be a 2D drawing. The four introductory meetings were in fact teaching foundations of DOS, then a specific design followed with the help of AutoCAD program. In the IX semester, for example, it was "A family house" (plans, facades, perspective). "I have to follow them - I am their leader" said L.J. Peter in "The Peter's Prescription". This quotation reflects exactly the situation we find ourselves in teaching CAAD at our department. It means that ever growing students interest in CAAD made us introduce changes in the curriculum. According to the popular saying, "The more one gets the more one wants", so did we and the students feel after the first semester of teaching CAD. From autumn 1991 CAAD classes will be carried from the third year of studying for two consecutive years. But before further planning one major steep had to be done - we decided to reverse the typical of the seventies approach to the problem when teaching programming languages preceded practical goals hence discouraging many learners.

summary	The rapid advances in sensor technology and processing hardware make the development of a Digital Photogrammetric System for Architectural Photogrammetry possible. This system is able to acquire images with sufficient resolution for Architectural Photogrammetry. Geometric and topologic information for a CAAD-System can be derived with manual and/or semi-automated methods. This paper describes the current status of such a system which is under development at the Institute of Geodesy and Photogrammetry in cooperation with the Chair of Architecture and CAAD, both at the Swiss Federal Institute of Technology in Zurich.

title	Computer Exercises in Architectural Design Theory
doi	https://doi.org/10.52842/conf.ecaade.1991.x.f9w
source	Experiences with CAAD in Education and Practice [eCAADe Conference Proceedings] Munich (Germany) 17-19 October 1991
summary	This paper discusses how architectural theory may be taught using computer based exercises to explore the practical application of those theories. The particular view of architecture developed is, necessarily, a restricted one but the objectives behind the exercises are slightly different to those that a pure architectural theorist or historian might have The formal teaching of architectural theory and composition has not been very fashionable in Schools of Architecture for several years now: indeed there is a considerable inbuilt resistance in students to the application of any form of rules or procedures. There is however a general interest in computing and this can be utilised to advantage. In concentrating on computer applications in design eclectic use has been made of a number of architectural examples ranging from Greek temples to the work of modern deconstructionists. Architectural theory since Vitruvius is littered with attempts to define universal theories of design and this paper certainly does not presume to anything so grand: I have merely looked at buildings, compared them and noted what they have in common and how that might relate to computer-aided design. I have ignored completely any sociological, philosophical or phenomenological questions but would readily agree with the criticism that Cartesian rationality is not, on its own, a sufficient base upon which to build a theory of design. However I believe there is merit in articulating design by separating it from other concerns and making it a subject of study in its own right. Work in design research will provide the models and intellectual structures to facilitate discourse about design and might be expected to benefit the development of design skills by providing material that could be formally taught and debated in a way that is removed from the ephemeral "fashionable designer" debate. Of course, some of the ideas discussed here may prove to be equally ephemeral but that does not entirely negate their value.

summary	This paper outlines a particular component of very well known project: Antoni Gaudí’s Sagrada Família Basilica in Barcelona (1882– on-going but scheduled for completion in 2026). At the time of writing the realisation of the project has proceeded for 87 years since Gaudí's death (1852-1926). As a building site it has been a living laboratory for the nexus between traditional construction offsite manufacturing and digital fabrication since the computers were first introduced to the project:CAD in 1989 closely followed by CAAD two years later. More remarkably CAD/CAM commenced its significant influence in 1991 with the take-up of sem robotised stone cutting and carving. The subject of this paper is an elevated auditorium space that is one of the relatively few ‘sketchy’ areas that Gaudí bequeathed the successors for the design of his magnum opus.

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.
