summary	The need to explore development techniques in computer-based design is reviewed. Some premises are given for design development using computers, including integrating multiple representations, the use of object-based modeling and the importance of visual analysis and 3-D modeling. We then present techniques used in a UCLA design studio that explored methods of computer-based design development based on these premises. The two main methods used were hierarchical object structures and multi-representational coordination. They were applied using conventional CAD systems. Some lessons learned from this class are reviewed.

title	ICAtect: Integrating Design Tools for Preliminary Architectural Design
source	Wellington, New Zealand: Computer Science Department, Victoria University
summary	ICAtect is a knowledge based system that provides an interface between expert systems, simulation packages and CAD systems used for preliminary architectural design. This thesis describes its structure and development.The principal work discussed in this thesis involves the formulation of a method for representing a building. This is developed through an examination of a number of design tools used in architectural design, and the ways in which each of these describe a building.Methods of enabling data to be transferred between design tools are explored. A Common Building Model (CBM), forming the core of the ICAtect system, is developed to represent the design tools knowledge of a building. This model covers the range of knowledge required by a large set of disparate design tools used by architects at the initial design stage.Standard methods of integrating information from the tools were examined, but required augmentation to encompass the unusual constraints found in some of the design tools. The integration of the design tools and the CBM is discussed in detail, with example methods developed for each type of design tool. These example methods provide a successful way of moving information between the different representations. Some problems with mapping data between very different representations were encountered in this process, and the solutions or ideas for remedies are detailed. A model for control and use of ICAtect is developed in the thesis, and the extensions to enable a graphical user interface are discussed.The methods developed in this thesis demonstrate the feasibility of an integrated system of this nature, while the discussion of future work indicates the scope and potential power of ICAtect.

title	Intra-Medium and Inter-Media Constraints
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 365-380
summary	Designers work with multiple representations in a variety of media to express and explore different kinds of knowledge. The advantages of multi-media in design are well- known, and exemplified by the current interest in 'hyper-media' approaches to knowledge exploration. A principal activity in working between views in one medium (e.g. plan, section and perspective drawings), or between different representations (diagrams, maps, graphs, pictures, e.g.) is extrapolating decisions made in one view or medium over to others, so that some consistency is maintained, and implications can be explored. The former kind of consistency maintenance (intra-medium) is beginning to be well understood techniques for constraint expression., satisfaction and propagation are starting to appear in 'smart CAD' systems. The latter kind of consistency maintenance inter-media.) is different, less well understood, and will require new mechanisms for constraint management and exploration. Experiments, hypotheses, and solutions in this direction will be central to any effort that seeks to explain, emulate or assist the integrative, synthetic reasoning that characterizes environmental design and planning. This paper examines some of the characteristics and advantages of intra and inter-media constraint exploration, describes a prototype "designers workstation" and some experiments in the context of landscape planning and design, and lays out some directions for development of these ideas in future computer aided design systems.

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.

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 basic assumptions for CAD, and for any use of computers, are re-examined. They refer to how we know things, how we think of knowledge being represented, and the impact of representation techniques on evolution of knowledge. Japan offers stimulating clues on how we might regard the usefulness of computers, and these are explained. Evocative illustrations are presented, to show a direction for future developments.

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	The Computer-Aided Studio Critic: Gaining Control of What We Look At
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 121-138
summary	This paper presents an approach to teaching that put computer resources in the hands of a studio instructor. A design professor or tutor that is expert in the use of the tool. The studio master used the computer to "study" the propositions of students. This was done as an extension of his current teaching practice. The critic used the computer as another tool additional to discussion, pencil and paper, and working models. Computer walk-throughs and visual representations of concepts were used by the professor to convey his interpretation of the work to students. In this model the students did not have to use the computer. The model recognized the years of experience and expensive equipment required to create an adequate representation of a design scheme and view it in the very short time period available during desk critiques. This approach for studio teaching has not been identified and discussed in any depth in recent literature on CAD studio teaching. The emphasis of papers presented at CAD conferences has been on how to provide students with better software and skills needed to make effective use of computers in their studio work.

title	SEED: A Software Environment to Support the Early Phases in Building Design
source	Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary	The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title	Analysis of design communication with and without computer mediation
source	Proceedings of Co-designing 2000, pp. 329-337
summary	With recent developments in CAD and communication technologies, the way we visualise and communicate design representations is changing. A matter of great interest to architects, practitioners and researchers alike, is how computer technology might affect the way they think and work. The concern is not about the notion of 'support' alone, but about ensuring that computers do not disrupt the design process and collaborative activity already going on (Bannon and Schmidt, 1991). Designing new collaborative tools will then have to be guided by a better understanding of how collaborative work is accomplished and by understanding what resources the collaborators use and what hindrances they encounter in their work (Finholt et al., 1990). Designing, as a more abstract notion, is different than having a business meeting using video conferencing. In design it is more important to 'see' what is being discussed rather than 'watch' the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the method with which it is communicated (See Kvan, 1994). Similarly, we believe that by using text instead of audio as a medium for verbal communication, verbal representations can then be recorded alongside graphical representations for later retrieval and use. In this paper we present the results of a study on collaborative design in three different environments: face-to-face (FTF), computer-mediated using video conferencing (CMCD-a), and computer-mediated using "talk by typing" (CMCD-b). The underlying aim is to establish a clearer notion of the collaborative needs of architects using computer-mediation. In turn this has the potential in assisting developers when designing new collaborative tools and in assisting designers when selecting an environment for a collaborative session.

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.

title	The CAD Design Studio: 3D modeling as a fundamental design skill
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!

summary	In the future of Computer Aided Architectural Design (CAAD), architects clearly need more than just computer aided design and drafting systems (CAD). Unquestionably CAD systems continue to become increasingly powerful, but there is more to designing a good building than its three-dimensional existence, especially in the eyes of all the non-architects of the world: users, owners, contractors, regulators, environmentalists. The ultimate measure of a building's quality has something to do with how well it behaves over time. Predictions about its performance have many different dimensions; how much it costs to build, to operate, and to demolish; how comfortable it is; how effectively people can perform their functions in it; how much energy it uses or wastes. Every year dozens of building performance simulation programs are being written that can predict performance over time along any of these dimensions. That is why the need for both CAD systems and performance predictors can be taken for granted, and why instead it may be more interesting to speculate about the need for 'design tools'. A design tool can be defined as a piece of software that is easy and natural for architects to use, that easily accommodates three-dimensional representations of the building, and that-predicts something useful about a building's performance. There are at least five different components of design tools that will be needed for the design environment of the future.

source	The Computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : ill. includes bibliography
summary	Improved models and methods for building representation are needed for more effective support of design integrity checking and control. A 'generic' object-oriented approach to product modelling allows multiple design representations to be described as different views of a common, gradually evolving building product model. The product model provides the capability to generate, in successive design iterations, a coherent description of the form, structure and dimensions of the building and its assemblies and components. Associated technological and administrative data can be included in or associated with the product description

source	Experiences with CAAD in Education and Practice [eCAADe Conference Proceedings] Munich (Germany) 17-19 October 1991
summary	We present a new method to derive a reliable 3D description of buildings and architectural models based on stereo vision using multiple camera views. This multi-view stereo technique has been successfully applied to many objects and has proved to be more reliable and more accurate than the well known binocular and even trinocular stereo techniques. The method has the following attractive features: (-) Flexibility: Arbitrary positions of an arbitrary amount of different camera views are allowed. (-) Automatic Calibration of each camera view is obtained by a simple procedure. (-) Reliable Stereo Analysis: The matching of corresponding image features of different images relies on a basic paradigm of Hypothesis Prediction and Validation. (-) Knowledge Base: Heuristics can be applied to correct the object reconstruction. (-) CAD-lnterface: The 3D description of the reconstructed object can automatically transferred via DXF to a CAD-system. (-) Low Costs: No special and expensive technical equipment like a laser or an UV rangefinder is necessary. A camera, a PC with CAD-system and a digitizing device like a digitizing tablet with a pointing pen are sufficient.

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	We describe the need for a joint effort between design researchers and simulation tool developers in formulating procedures and standards for integrating simulation into the building design process. We review and discuss current efforts in the US and Europe in the development of next-generation simulation tools and design integration techniques. In particular, we describe initiatives in object-oriented simulation environments (including the US Energy 'Kernel System, the Swedish Ida system, the UK Energy Kernel System, and the French ZOOM program.) and consider the relationship of these environments to recent R&D initiatives in design integration (the COMBINE project in Europe and the AEDOT project in the US).

source	Experiences with CAAD in Education and Practice [eCAADe Conference Proceedings] Munich (Germany) 17-19 October 1991
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.

title	Modelling Interaction Tools in the Views Architecture IV. Design Tools
source	First Moscow International HCI'91 Workshop Proceedings 1991 p.183
summary	Views is a user-interface system in which the user interface is a layer above applications, guaranteeing consistency of the interface, and with a data-layer implementing external object representations, allowing exchange of objects between applications without loss of structure. Although Views offers an architecture to deal with user-interface aspects on a high level, in this report is shown that also low level interaction can be modelled with the architecture provided.
