title	Computer Methods in Architectural Problem Solving : Critique and Proposals
source	Journal of Architectural and Planning Research. Spring, 1989. vol. 6: pp. 34-54 : ill. includes bibliography
summary	While the development of modelling and drafting tools for computer-aided design has reached a state of considerable maturity, computerized decision support in architectural sketch design is still in its infancy after more than 20 years. The paper analyzes the difficulties of developing computer tools for architectural problem solving in the early stages of design where decisions of majors importance are made. The potentials of computer methods are discussed in relation to design as a static system of information, and to design as a creative process. Two key problems are identified, and on this background current computer methods intended for use in architectural sketch design are critically reviewed. As a result some guidelines are suggested for future research into computer-aided architectural problem solving. The purpose of the paper is twofold: (1) to encourage research that will take this field into a state of maturity and acceptance by practitioners, and (2) to provoke further debate on the question of how to do it

summary	To bring together poetry, magic and science, to explore beyond preconceptions, to invent spaces and forms which re-form and inform man's experience, these are the possibilities of architecture. Computer integrated design offers a means for extending the search, one which integrates both conceptual and perceptual issues in the making of architecture. The computer may assist in generating constructs which would not have been created by conventional methods. The application of computer techniques to design has to date been focused primarily on production aspects, an area which is already highly organizable and communicable. In conceptual and perceptual aspects of design, computer techniques remain underdeveloped. Since the impetus for- the development of computer applications has come from the immediate economics of practice rather than a theoretically based strategy, computer-aided design is currently biased toward the replication of conventional techniques rather than the exploration of new potentials. Over the last two years we have been involved in experimentation with methodologies which engage the computer in formative explorations of the design idea. Work produced from investigations by 4th and 5th year undergraduate students in computer integrated design studios that we have been teaching at the University of Southern California demonstrates the potential for the use of the computer as a principal tool in the exploration of syntax and perception, space and program. The challenge is to approach the making of architecture as an innovative act, one which does not rely on preconceived notions of design.

title	Computing and Design in the Canadian Schools of Architecture and Landscape Architecture: A Proposed Research Agenda for Integrated CAD & GIS in the 1990's
source	New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 227-244
doi	https://doi.org/10.52842/conf.acadia.1989.227
summary	Conventional computer systems currently used by architecture and landscape architecture are not addressing complex decision making, system interface, dynamic manipulation and real time visualization of data. This paper identifies a strategy by which Canadian Schools could form a supportive network, incorporate and expand their research development. Within this larger framework schools would have better tools, a larger research base and access to funding as a group. The following discussion is an idea of what we at the Canadian Schools need to do differently over the next five years in our research and teaching in order to make a unique contribution to our fields.

title	Irises in a Landscape: An Experiment in Dynamic Interaction and Teaching Design Studio
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 363-376
summary	The capacity of most computer-aided design systems is inadequate to represent landscape architectural ideas and compute landscape scenes quickly. As part of our teaching agenda, we decided to write software for the Silicon Graphics Iris workstations to tackle this problem directly. This paper begins with a discussion of our concerns about the use of CAD tools in the representation of landscape architectural space. Secondly, we discuss the approach that Toronto takes to computing and teaching with particular emphasis on the use of computers to support an integrated representational work environment. Finally, a fourth-year design studio that used our software is reviewed. Static illustrations of the system are presented here, although there is a videotape that demonstrates the dynamic nature of the system.

summary	The Video and Multimedia studio at VTT, Technical Research Centre of Finland, started with endoscopy photography of scale models. Video recordings has been made since 1985 and computer graphic since 1989. New visualization methods and techniques has been taken into use as a part of research projects, but mainly we have been working with clients commissions only. Theoretical background for the visualizations is strong. Research professor Hilkka Lehtonen has published several papers concerning the theory of visualization in urban planning. This studio is the only professional level video unit at Technical Research Centre, which is a large polytechnic research unit. We produce video tapes for many other research units. All kind of integrated methods of visualization are useful in these video productions, too.

title	Case Studies in Moviemaking and Computer-Aided Design
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 393-412
summary	A movie which is developed from site location video, sync sound, and computer graphics animation can provide a highly convincing simulation of reality. A movie that conveys a sense of the space, materials and juxtaposition of objects of a proposed architectural design provides a special kind of realism, where the representation may be of a proposed building that exists only within the mind of an architect. For an experienced architect, however, the movie may not provide a good surrogate experience for what it feels like to actually be within the architectural space. In these case studies, a few projects that combine moviemaking and computer-aided design technologies are examined. These projects were completed using a combination of resources at the MIT School of Architecture and Planning and the Harvard Graduate School of Design. The integrated use of these media is presented as conceptualized with the Electronic Design Studio, a research project that has been supported over the past five years by Project Athena at MIT. The impact of movies and computer-aided design on the perception of architectural space is also reported- based on a pilot study of twenty architectural students.

summary	We present an integrated set of programs as CAD-tools for the design of shapes, evaluation of stress field and displacements of tensile membrane structures as well as a way to find out their surface patterns. In early times simulation of physical small models has been used to obtain a phenomenological view rather than quantitative information about these structures. A progressive way has been thought to make a comprehensive an practical approach to this kind of structure, characterized by its ability to offer displacements of long range. We propose like a first steep a rough simulation through elastic member models or elastic-surface models. An iterative process starts, based on visualizations through different peripheric devices (screened and plottered graphic outputs). This first steep ends by the formulation of an optimum geometric performances of the structure. The resulting geometry serves like a source structure for a more accurate calculus achieved by the Finite Element Method. Discretization of the continues structure is carried out in a network of tiny triangular elements. Finally, 3-D realism techniques has been used to represent the form adopted or stress field calculated or both at the same time, by an adequate use of the color attributes of the finite elements.

summary	This paper is about the backgrounds, the present state, the results and the future expectations of the curriculum of Calibre, at the Faculty of Architecture and Building Science of the Eindhoven University of Technology. It will also touch upon the relationships with project work in our field but also in other fields of our Architectural (and Building) education. In the paper it is emphasised that teachers need to create a need for the use of certain features of computer systems. To make students aware of the (possible) CAD needs and answering to those needs at a more or less individual way asks a high level of understanding of the underlying concept and features of the CAD systems. Because of the flexibility (amongst other qualities), we, and so many others, have made a choice to use AutoCAD as 8 kind of thread that runs through our curriculum continuously and that exists out of 6 main parts. These parts vary from an introduction to Integrated Data Processing via CADD, Graphics and Data Structures and Expert Systems to System Development Methods. Half of our curriculum Is compulsory for all the faculty students, the other half is facultative but very well attended.

title	Splitting Set-Theoretic Solid Models into Connected Components
source	10 p. : ill. Winchester: IBM UK Scientific Center, IBM United Kingdom Laboratories Limited, June, 1989. IBM UKSC 210. includes bibliography In general, there is no way to tell how many pieces (connected components) a set-theoretic (CSG) solid model represents, except via conversion to a boundary model. Recent work on the elimination of redundant primitives has been linked with techniques for identifying connected components in quad-trees and oct-trees into a strategy to attack this problem. Some success has been achieved, and an experimental Prolog program, working in two dimensions, that finds connected components and determines the set-theoretic representation of each component, is reported, and further developments proposed.

April, 1982. pp. 89-95 : ill. includes bibliography.
summary	A major problem with volume modelling systems is that processing times may increase with model complexity in a worse than linear fashion. The authors have addressed this problem, for picture generation, by repeatedly dividing the space occupied by a model, and evaluating the sub-models created only when they meet a criterion of simplicity. Hidden surface elimination has been integrated with evaluation, in such a way that major portions of the model which are not visible are never evaluated. An example demonstrates a better than linear relationship between model complexity and computation time, and also shows the effect of picture complexity on the performance of the process

title	Intuition & Computer Visualization in an Urban Design Studio
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 4.2.1-4.2.6
doi	https://doi.org/10.52842/conf.ecaade.1989.x.i5v
summary	This paper will present prototypical software being used in the teaching of urban design to students and for use by professionals in the early stages of a project. The system is intended to support a heuristic approach to design. That is, it supports a process of refining ideas and understandings through a process of trial and error. The support or aid to design comes in the form of a didactic real-time programme. Its power lies in its ability to provide instantaneous response to operations on the data that can allow one to develop three-dimensional spatial ideas in an intuitively driven manner. This condition appears to occur for both novice and expert computer operators. The presentation will present our experience to-date in using conventional computer graphic tools to represent design ideas and contrast it with a video demonstration of ow prototypical dynamic urban design modelling software for the Silicon Graphics IRIS computers.

title	Architecture and Industrial Design A Convergent Process for Design

summary	The use of technology has grown with the way design professions have evolved over time. Changing needs, desires of comfort, and perceptions of the consumers have led to a distinct improvement in the design of both product and architecture. The use of the digital media and emerging technologies has brought a dramatic change to the design process allowing us to view, feel, and mould a virtual object at every stage of design, development, and engineering. Change is often quick and easy since a virtual product does not inherently carry the biases of its physical counterpart. In order to communicate ideas across the team, digital processes are also used to bring together opinions, experiences, and perspectives. These methods encourage decision making based on information rather than prejudice or instinct. Thus, digital exchanges (technology) impact firm strategies at three levels: product, process, and administrative or support activities (Adler 1989).Digital tools for design exchange in Industrial Design (ID) began much earlier than many other professions. The profession of Architecture is also slowly moving to a similar model with digital exchange finding increasing prevalence in drawing, modeling, performance simulation, design collaboration, construction management, and building fabrication. The biggest problem is the disintegrated use of technology in the architectural profession without a strategy toward streamlining the design process from conception to fabrication. In this paper we investigate how the use of technology has evolved in the professions of Industrial Design and Architecture comparatively in their product, process, and support activities. Further, we will present a set of guidelines that will help architects in the convergence of design process, helping in a more efficient work flow with a strategic use of digital technology.

doi	https://doi.org/10.52842/conf.ecaade.1989.x.w0q
summary	This paper describes the use of a widely-used CAD drafting system, in conjunction with a specialist contouring package, to provide a low-cost facility for terrain modelling, volumetric calculation, and landscape visualisation. One such system is in use at the Department of Architecture & Landscape, Manchester Polytechnic, to enable graduate students on the Landscape Design course to explore the visual and quantitative implications of design proposals, particularly when related to large scale landscape modelling. It is also in commercial use by professional surveyors, waste management contractors, local authorities etc. In addition to AutoCAD, two further packages are employed, one to recover coordinates from existing AutoCAD drawings, and the other to generate contours and volumes from those, or other coordinate data files. The first known as BADGER (Basic AutoCAD Data Grabber & Exchange Routine), and the other is SURVCAD CONTOURS - a contouring program capable of converting large coordinate data files (2500 + points) to a 2.5D terrain model.

summary	Knowledge-based systems are becoming pervasive in the computer-aided design area. For these systems to achieve satisfactory levels of performance large amounts of knowledge are necessary. However, the acquisition of knowledge is a difficult and tedious task. Automated knowledge-acquisition tools (AKAT) provide capabilities for quickly building and maintaining knowledge-bases. This paper describes the CGEN AKAT, which allows hardware designers, unfamiliar with artificial intelligence programming techniques, to deposit their expertise into a synthesis tool's knowledge-base. A set of experiments which tested CGEN's capabilities are presented. The experiments show that with CGEN hardware designers can produce high quality knowledge-bases

summary	Focusing on the tasks of university architectural education, a special stress is first laid on the possibility of going beyond some limits of traditional CAAD. as coming out from the recent debate, and on the opportunities offered by knowledge based systems as metadesign supports in architectural domains. Particularly, with regard to image-databases, their importance for explaining and exemplifying the knowledge representation in KB Systems, and their integration via intelligent interface are discussed. At last, some possible uses of the whole as an educational tool in the daily university training are proposed.

summary	The highly developed glasfiber technology of the Berlin ISDN-B prototype network will make it possible to test a future benefit of the possibilities of real time visual communication for architects and planers in their home office. In the project an external user will be able to share high end visual outputs of a Service Center for Visualisation with his own low end CAAD workstation via ISDN-B. The capabilities of these services will range from a still picture archive, real time access to video film archive, a variety of conventional database services to special postproduction for his own 3D data models. The transferred 3D model can be rendered an animated on the Center's systems, if requested also integrated into a video background film. The production will than be available on his workstation screen. These new means will be evaluated in the view of the architects new possibilities for the design process.

summary	Rapid advances in semiconductor technology are motivating the development of computer-aided design tools to assist human designers at the higher levels of the design process. In particular, there is a need for tools that aid system-level design synthesis - the process of producing a detailed artifact satisfying high level specifications given a set of components. A knowledge-based approach that uses a hierarchical design synthesis methodology is described. M1 is a knowledge-based system that implements the approach for the domain of single board computer design. A set of experiments which indicate M1's capabilities and the effectiveness of the approach in organizing and utilizing knowledge are presented

title	CAD geometry data exchange using STEP
source	Berlin: Springer-Verlag
summary	With increasing demand for data exchange in computer integrated manufacturing, a neutral connection between dissimilar systems is needed. After a few national and European attempts, a worldwide standardization of product data has been developed. Standard ISO 10303 (STEP - STandard for Exchange of Product data) produced in its first version those parts that are relevant for CAD geometrical data. A European consortium of 14 CAD vendors and users was supported by the ESPRIT programme to influence the emerging standard and implement early applications for it. Over the years 1989-1992, project CADEX (CAD geometry data EXchange) worked out application protocols as a contribution to STEP; developed a software toolkit that reads, writes, and manipulates STEP data; and, based on this toolkit, implemented data exchange processors for ten different CAD and FEA systems. This book reports the work done in project CADEX and describes all its results in detail.

title	The Hybrid Edge : A Topological Data Structure for Vertically Integrated Geometric Modeling
source	Computer Aided Design. April, 1989. vol. 21: pp. 129-139 : ill. includes bibliography
summary	Generalizing the computational geometric support for the representation of designed artifacts over multiple different levels of symbolic abstraction (e.g., sketches, solid modeling, and drafting) is discussed. First, the need for integrating the representation and manipulation of points, lines, polygons and solids for the purpose of facilitating the design of artifacts at many levels of design abstractions established. Second, a vertically integrated model that supports the representation and manipulation of points, lines, polygons, and solids without redundancy, is presented. The particular roles of the operators and the operandi are discussed, along with their hierarchical integration. The utility of the model is demonstrated in performing operations that involve multiple different levels of data abstraction, such as splitting solids at an arbitrary polygon inscribed on their boundary. Finally, a particular implementation of the integrated model is presented. This implementation is based on the Hybrid Edge, a derivative from Baumgart's Winged Edge and Eastman's Split Edge models. The Hybrid Edge distinguishes between the roles of edges as topological adjacency information carriers and their role as carriers of directionality information. This distinction permits the Hybrid Edge to handle the different combinations of adjacency and directionality requirements imposed by different abstraction levels in the integrated model
