summary	"Design tools affect the results of the design process" - this is the starting point of our considerations about the efficient use of CAAD within architecture. To give you a short overview about what we want to say with this thesis lets have a short - an surely incomplete - trip through the fourth dimension back into the early time of civil engineering. As CAD in our faculty is integrated in the "Lehrstuhl für Hochbaustatik und Tragwerksplanung" (if we try to say it in English it would approximately be "institute of structural design"), we chose an example we are very familiar with because of its mathematical background - the cone sections: Circle, ellipse, parabola and hyperbola. If we start our trip two thousand years ago we only find the circle - or in very few cases the ellipse - in their use for the ground plan of greek or roman theaters - if you think of Greek amphitheaters or the Colosseum in Rome - or for the design of the cross section of a building - for example the Pantheon, roman aqueducts or bridges. With the rediscovery of the perspective during the Renaissance the handling of the ellipse was brought to perfection. May be the most famous example is the Capitol in Rome designed by Michelangelo Buonarotti with its elliptical ground plan that looks like a circle if the visitor comes up the famous stairway. During the following centuries - caused by the further development of the natural sciences and the use of new construction materials, i.e. cast-iron, steel or concrete - new design ideas could be realized. With the growing influence of mathematics on the design of buildings we got the division into two professions: Civil engineering and architecture. To the regret of the architects the most innovative constructions were designed by civil engineers, e.g. the early iron bridges in Britain or the famous bridges of Robert Maillard. Nowadays we are in the situation that we try to reintegrate the divided professions. We will return to that point later discussing possible solutions of this problem. But let us continue our 'historical survey demonstrating the state of the art we have today. As the logical consequence of the parabolic and hyperbolic arcs the hyperbolic parabolic shells were developed using traditional design techniques like models and orthogonal sections. Now we reach the point where the question comes up whether complex structures can be completely described by using traditional methods. A question that can be answered by "no" if we take the final step to the completely irregular geometry of cable- net-constructions or deconstructivistic designs. What we see - and what seems to support our thesis of the connection between design tools and the results of the design process - is, that on the one hand new tools enabled the designer to realize new ideas and on the other hand new ideas affected the development of new tools to realize them.

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

title	Design Tool Integration: Model Flexibility for the Building Profession
source	Proceedings of Building Systems Automation - Integration, University of Wisconsin-Madison
summary	The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by simulation tools, can be used to converse with knowledge-based systems. We consider the types of mappings that occur in the often different views of a building held by these two classes of design tools. This leads us to examine the need for multiple views of a common building model. We then extend our analysis from the views required by simulation and knowledge-based systems, to those required by different segments of the building profession (e.g. architects, engineers, developers, etc.) to converse with such an integrated system. This indicates a need to provide a flexible method of accessing data in the common building model to facilitate use by different building professionals with varying specialities and levels of expertise.

title	A Common Data Model for Computer Integrated Building
source	computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : some ill. includes bibliography
summary	The connection of various building performance evaluation tools in a collaborative way is an essential request to develop true CAD systems. It is a basic requirement for the future of integrated information systems for building projects, where data concerning multiple aspects of the project can be exchanged during the different design steps. This paper deals with the on-going research concerning the generation of a common data model in the framework of a European collaborative action, the COMBINE Project, which is supported by the CEC, General Directorate XII for Research Science and Development, within the JOULE programme. The first step of the research concerns the progressive construction of a conceptual model and the paper focuses on the development of this Integrated Data Model (IDM). The paper reports on the definition of the architecture of the IDM. The main issues and the methodology of the IDM development are presented. The IDM development methodology is based on successive steps dealing with the identification of the data and context which are considered by the Design Tool Prototypes (DTP) to be connected through the IDM, the conceptual integration of this knowledge, and the implementation of the model on an appropriate software environment

title	Intelligent Systems for Supporting Architectural Design

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

summary	With the development of ubiquitous computing (Weiser, 1991), what will become of the traditional media such as pen and sketches, especially in the design education environment? Or what will they be transformed into? In this research, we focus on the interior design process with a particular type of media-1:1 spatially augmented reality design environment (SARDE). In this research, we tried to implement SARDE and have a scenario experiment to check how designers interact with such design media. Furthermore, through this research, we have come to know more about how designers use design media to represent their design dream.

title	The Limitations of Current Working Practices on the Development of Computer Integrating Modelling in Construction
source	computer Integrated Future, CIB W78 Seminar. Calibre, The Netherlands: Eindhoven University of Technology, september, 1991. Unnumbered. includes bibliography
summary	For the construction Industry to improve its processes through the application computer-based systems, traditional working practices must first change to support the integrated control of design and construction. Current manual methods of practice accept the limitations of man to process a wide range of building performance and production information simultaneously. However when these limitations are removed, through the applications of computer systems, the constraints of manual methods need no longer apply. The first generation of computer applications to the Construction Industry merely modelled the divided and sequential processes of manual methods i.e. drafting, specification writing, engineering and quantity calculations, estimating, billing, material ordering data-bases and activity planning. Use of these systems raises expectations that connections within the computer between the processes modelled can actually be made and faster and more integrated information processing be achieved. 'Linking' software is then developed. The end result of this approach was that users were able to produce information faster, present it in an impressive manner but, in reality, no perceived improvement in actual building performance, production economy or efficiency was realized. A current government sponsored Teaching Company Programme with a UK design and build company is addressing the problem of how real economic benefit can be realized through improvement in, amongst other things, their existing computer applications. This work is being carried out by both considering an academic conceptual model of how 'designing for production' can be achieved in computer applications and what is immediately realizable in practice by modelling the integration of a limited number of knowledge domains to which computers are already being applied. i.e. billing from design, estimating and buying. This paper describes each area of work and how they are impacting on each other

title	Dynamic Information System for Modelling of Design Processes
source	Computer Integrated Future, CIB W78 Seminar. september, 1991
summary	Unnumbered : ill. DINAMO is a Dynamic Information System for Modelling of Design Processes. It is intended for use along with product models, data management systems and existing applications. In DINAMO a programming user can define processes. These processes are represented by graphs. The graphs are characterized by nodes and relations between nodes. Each node in a graph represents a task, and each relation can be restricted to conditions. So the way in which a process is actually being performed, that is, the actual path to be evaluated through the graph, can depend on certain conditions. Processes and functions (=software modules) are available to the user as tasks. A consuming user can activate tasks; the DINAMO system regulates the dispatch of the tasks, conform the process and function definitions. Tasks are collected on sheets; sheets are collected in a task box. A task box can be regarded as a certain environment, determined by the programming user. A consuming user can choose between the environments which are available at that moment. With the DINAMO system software and process definitions can be re-used in a simple way

summary	Spatial productivity is the first of the elements comprising sensMOD, a student elective that implemented a methodology addressing the exigent need of our time for transformation in the architecture, engineering and construction (AEC) sector. The second and third elements of sensMOD are parts and interaction which focus attention on the nature of complexity and connectivity in our networked world. The paper proposes a methodology that was used to guide the teaching of an elective for third year architecture students at a UK university. Its wider purpose is to contribute to discussion concerning the dysfunctional state of an AEC sector that needs to consider its productivity as projections of wider networks of resource and energy relationships. Henri Lefebvre's spatial theory (1991) guides the narrative and formulation of sensMOD.

summary	I have been working on an architecture representation system in India since 1991; that markedly deviates from the need of traditional drawings as we know. Over three million square feet of work has been done that took advantage of this system as it was being developed. The system has now matured sufficiently to be put into practice as a comprehensive architectural system of practice. It takes advantage of creation of just-in-time dynamic multi-organizations that can get formed (and dismantled) over the Internet on a project to project basis. The raison d’être of the representation system is that it would expose the “source-code” (metaphorically) of any work of architecture to stakeholders, much the same way as an open-source software project exposes the internal representation to fellow developers. I believe the design of architecture must go through an “open source” process in order to produce socially responsible designs. Such a stance is explained in this paper. The paper also explains the system in detail; its mathematical basis and justifies the need for such an approach. It also explores how a collaborative practice can be put into place using the system in the context of Internet technologies.

title	Ten problems for AI in design
source	Workshop on AI in Design, IJCAI-91, un-numbered
summary	Modern design research dates back to the end of the eighteenth century when French theorists attempted to describe design as a process. The notion of process in design dates back to the Roman engineer/architect/writer Vitruvius who described both process and performance aspects of designing. Since the 1940s there has been a variety of attempts to provide formal models of design ranging from prescriptive algorithmic-like descriptions through mathematical model and systems theoretic descriptions to the current paradigm based on the precepts and notions of artificial intelligence. All of these, including the current work, is primarily concerned with treating the process aspects of design.

title	Integrated Component-based Computer Design Modeling System: The Implications of Control Parameters on the Design Process
source	New Jersey Institute of Technology, Newark, NJ Graduate Thesis - Master's Program College of Architecture
summary	The design process is dependent on a clear order of integrating and managing all of the control parameters that impact on a building's design. All component elements of a building must be defined by their: Physical and functional relations; Quantitative and calculable properties; Component and/or system functions. This requires a means of representation to depict a model of a building that can be viewed and interpreted by a variety of interested parties. These parties need different types of representation to address their individual control parameters, as each component instance has specific implications on all of the control parameters. Representations are prepared for periodic design review either manually through hand-drawn graphics and handcrafted models; or with the aid of computer aided design programs. Computer programs can profoundly increase the speed and accuracy of the process', as well as provide a level of integration, graphic representation and simulation, untenable through a manual process. By maintaining a single control model in an Integrated Component-based Computer Design Modeling System (ICCDMS), interested parties could access the design model at any point during the process. Each party could either: 1. Analyze individual components, or constraints of the model, for interferences against parameters within that party's control; or 2. Explore design alternatives to modify the model, and verify the integration of the components or functions, within the design model, as allowable in relation to other control parameters.

source	McGraw-Hill, New York
summary	Until now, books on CAD aimed at architects have addressed the use of computer-aided design and drafting as a recording tool, a faster means of producing and storing finished working drawings-and not as an adjunctive creative tool for the design process. Without being software specific, this book will guide the professional and student architect and graphics designer in how to use the computer as an electronic modelling tool, exploring graphic and geometric forms and systems with the freedom and speed of the computer. The reader will be led through a progression of design exercises and design problems, learning how to come up with multiple solutions to a given program. Beautifully illustrated throughout, including 10 four-color CAD drawings!

title	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

title	An Intelligent Simulation Approach in Simulating Dynamic Processes in Architectural Environments
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 177-190
summary	The implications of object-oriented data models and rule-based reasoning systems is being researched in a wide variety of application areas ranging from VLSI circuit design (Afsannanesh et al 1990) to architectural environments (Coyne et al 1990). The potential of this approach in the development of discrete event simulations is also being scrutinized (Birtwistle et al 1986). Such computer models are usually called "expert simulations" or "intelligent simulations". Typically rule-basing in such models allows the definition of intelligent-objects that can reason about the simulated dynamic processes through an inferencing system. The major advantage of this approach over traditional simulation languages is its ability to provide direct reference to real world objects and processes. The simulation of dynamic processes in architectural environments poses an additional Problem of resolving the interaction of architectural objects with other objects such as humans, water, smoke etc., depending on the process simulated. Object-oriented approach promises potential in solving this specific problem. The first part of this paper addresses expert simulation approach within the context of architectural settings, then the second part summarizes work done in the application of such an approach to an emergency egress simulation.

title	Observations on daylighting as demonstrated by the work of Alvar Aalto
source	Kent State University
summary	Daylight plays a dominant role in the works of Finnish architect Alvar Aalto. This thesis project investigates the role played by the natural light in his architectural works. One of the major concerns of this paper is to discover his intent behind the use of daylight, as well as to identify some of the techniques he devised to handle daylight. Literature research and physical model simulation studies have been incorporated as a method for the study. Significant works of Aalto have been surveyed. It has been observed that the use of daylight has been one of the preoccupations of Aalto since the design of Viipuri Library and Paimio Sanatorium. It was also observed that skylights play a prominent role in Aalto's architecture and that they are well developed and sophisticated devices. Some of the technical components and contributing factors of Aalto's skylights have been identified. Three case-studies were conducted through literature research and simulations. It was concluded that Aalto treats daylighting as one of the elements to embody sufficient psychological factors in man's built environment. It was discovered that the selection and the detailing of the skylights in each case has been predominantly guided by the climate, function, personal relationships, and the visual task of the individual space. Physical model simulations proved to be extremely helpful in understanding the modeling of the daylight and the spatial quality.

title	Object-Oriented Modelling and Design
source	Englewood Cliffs, NJ: Prentice Hall
summary	Object-oriented modelling and design promote better understanding of requirements, cleaner designs and more maintainable systems. Often, books on related subjects rely on programming and coding, forcing readers to think in terms of the computer, and not the application. "Object-oriented Modeling and Design" emphasizes that object-oriented technology is more that just a way of programming. It applies techniques to the entire software development cycle. This volume presents a new object-oriented software development methodology - from analysis, through design, to implementation. Key features of the book include a focus on high-level, front-end conceptual processes of analysis and design, rather than just on the low-level, back-end implementation steps of programming; coverage of the entire development life cycle - analysis, design, implementation without a change of notation at each stage; a presentation of graphical notation and methodology independent of any particular programming language; case studies of industrial object-oriented applications developed by the authors; and examples and exercises that bring out fine points, summary lists of concepts and methodology steps, and almost 300 diagrams.

title	Conceptual Design by Means of Islamic-Geometric-Patterns within a CAAD-Environment
source	Delft University of Technology
summary	The starting point in this research was to develop a 3D grammar theory on top of existing 2D Islamic-geometric-patterns, trying to rescue their fundamental geometry contents to be applied in contemporary architecture without compromising any architectural style. As it is self evident the architectural design process consists of clearly distinct stages namely conceptual design, materialisation and further completion. A this conceptual stage the innovative item of the research deals with pattern grammars on 3D complex geometrical patterns, considering them as polyhedra and polytopes, for their use as an underlayer to a concept design, like architects use 2D rectangular and triangular grids by the conventional way. Handling these complex 3D patterns requires a special environment which is possible with CAAD. Within the CAAD environment, the handling of these complex patterns is easily done by means of 3D tools, because the 3D tools permit the user to make any possible manipulations and geometrical transformations in an easier way in space. To a geometrical patterns, there is some attention paid during the last 50 years by some scholars. The most complex geometrical patterns are highly developed in Islamic architecture because it is forbidden in Muslim religion to use man's portraits or sculptures of human beings in the religious buildings. All these approaches to complex patterns are analysed and studied as 2D elements. The question was how could we consider them in 3rd dimensions and use them instead of 2D underlayer, as 3D underlayers in the conceptual phase of the CAAD design. Pattern grammar is a generally employable aid (underlying pattern) for conceptual and material designs. On the basis of rules of symmetry and substitution, ordering principles have been worked out, which can be used for formal design methods as well as detailing systems (e.g. modular coordination). Through the realization of a pattern grammar a wider range of underlying patterns can be offered and a choice from these can be made in a more fundamental manner. At a subsequent stage the collection of "empty boxes" can be filled with (architectural) elements in such a way that another option is created between either filling up the boxes completely, filling them partly, or filling them in such a way that they overflow. It is self-evident that underlying patterns can also be used for details and decoration in a design. Concerning the materialisation of the concept design, within the 3D CAAD environment, substitution methods are partially developed. Further theoretical developments concerning the materialisation phase constantly backed up through feed-back with specialist matters (such as e.g. by means of expert systems, decision-support systems), must be worked out. As feed-back of the research, the possibilities of the design with 3D patterns have been tested and the procedures are explained. () Working with 3D patterns gives a designer more inspirations to develop new ideas and new concepts and gives the opportunity to handle the complexity. () The formal, structural and symmetrical qualities of geometrical patterns has a positive influence on the industrialisation of the building components. (*) Working with 3D tools which are able to handle complex geometry have a result because of the accuracy of the information, that there has hardly been a mistake made during the preparation and the assembly of the building components. This has also positive results concerning the financial aspects of the building process.
