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.

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. 413-426
summary	This is a case study of teaching at the University of Texas at Austin. It is about using an electronic design studio to provide architecture students with their first exposure to computing. It suggests that, despite the limitations of present technology, there is reason to lower the thresholds to computer-aided design. The study presents a studio which attempted such by allowing students to find their own level of commitment to use of electronic media for geometric modeling. More generally, the paper aims to document issues presently facing the many professional schools not having substantial traditions in computer-aided design education.

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.

title	A Direct Generative CAD Tool for the Site Layout of Communities With Solar Access to Each Building
doi	https://doi.org/10.52842/conf.ecaade.1989.x.x6o
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 9.17.1-9.17.9
summary	A method for the design of communities with solar access to each building is presented. The method allows the determination of the minimum possible distance between the buildings that enables insolation, the maximum height allowed for a given building without violating the "Solar Rights" of its neighbors, and how low the window or the passive solar collector can be placed on the wall and still be insolated in winter. The fundamental idea is to use a computer and CRT to generate the entire envelope of the families of design solutions. These solutions provide the required open space between buildings to sustain the "Solar Rights" of the building under consideration. This envelope of solutions serves as a nomogram on the basis of which the location of each building in the solar communities is determined. The method creates an unlimited space of solutions, leaving the final design to the architect's imagination.

title	New Ideas and Directions for the 1990’s [Conference Proceedings]
doi	https://doi.org/10.52842/conf.acadia.1989
source	ACADIA Conference Proceedings / Gainsville (Florida - USA) 27-29 October 1989, 262 p.
summary	About a year ago, a comment of mine to Bob Johnson that recent Acadia Conferences appeared to be bypassing some of the real issues of CAAD and that the attendants seemed to be missing the opportunity to debate and to argue, landed me a request to be the Technical Chair for this Acadia 89. In spite of an expected heavy load this past year, I could not refuse. I certainly did not realize at the time what it would take to put the technical program of this Conference together: two "calls" for papers, many- many phone calls and the gracious acceptance of three invited speakers and twelve panelists. In response to a recommendation by Pamela Bancroft, last year's Technical Chair, the first call for papers had a deadline which was by about a month earlier than it has been in recent years. This must have found our membership unprepared and generated only thirteen submissions. A second call was issued with the end of July as a deadline. It generated another eleven submissions. Out of that total of twenty-four papers, ten were selected and are presented in this Conference. The selection process was based strictly on averaging the grades given by each of the three referees who blindly reviewed each paper. The names of the reviewers have been listed earlier in this volume and I wish to take this opportunity to wholeheartedly thank them. In most cases the reviewers offered extensive comments which were returned to the authors and helped them improve their papers. Many of the papers have actually been rewritten in response to the reviewers' comments and what are included in these Proceedings are substantially improved versions of the papers originally submitted. This is the way it is supposed to be, but could not be done without the excellent response by the authors. I"hey deserve our sincere thanks. It must be noted that the reviewers were not always in agreement, which should tell us something about the diverse orientations of our members. In the case of at least three papers, one reviewer gave a 0 or 1 (very low) when another gave a 9 or 10 (very high). In these cases the third reviewer gave the deciding grade. In no case was there a need for me to break a tie. Under normal circumstances, these "controversial" papers should have gone out for another cycle of reviews. Time did not permit to do so. However, I feel confident that the papers which have been selected deserve to be heard. It may be worth speculating why it took two calls to generate only 24 submissions when last year we had 42. There are a number of factors which must have had an effect. First of all, the early deadline. Secondly, the theme of this year's Conference was more focussed than it has been in the recent past. In addition, it was quite challenging. Even though the calls also encouraged submissions in areas other than the central theme, they discouraged contributions which might be redundant with past presentations. This must have filtered out presentations about "CAD in the studio" which did not have an orientation distinctively different from what everybody else is doing. Last, but possibly the most decisive factor must have been that, this year, Acadia was in competition with the Futures Conference. It does not take much to observe that more than half of the presentations at the CAAD Futures Conference were given by active Acadia members. Acadia should by all means be delighted that the bi-annual Futures took place in the States this year, but it certainly made our organizational task harder. As a matter of fact, as a record of CAAD happenings in 1989, 1 believe the Proceedings of the two Conferences complement each other and should be read as a pair.

title	The Computerized Design Firm
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. 317-332
summary	This paper is not just about the future of computerized design practice. It is about what to do today in contemplation of tomorrow-the issues of computercentered practice and the courses of action open to us can be discerned by the careful observer. The realities of computerized design practice are different from the issues on which design education still fixes its attention. To educators, the present paper recommends further clinical research on computerized design firms and suggests that case studies on the matter be developed and utilized as teaching material. Research conducted by the author of this paper indicates that a new form of design firm is emerging-the computerized design firm-totally supported and augmented by the new information technology. The present paper proceeds by introducing an abridged case study of an actual totally electronic, computerized design practice. Then, the paper concentrates on modelling the computerized design firm as an intelligent system, indicating non-trivial changes in its structure and strategy brought about by the introduction of the new information technology into its operations - among other considerations, different strategies and diverse conceptions of management and workgroup roles are highlighted. In particular, this paper points out that these structural and strategic changes reflect back on the technology of information with pressures to redirect present emphasis on the individual designer, working alone in an isolated workstation, to a more realistic conception of the designer as a member of an electronic workgroup. Finally, the paper underlines that this non-trivial conception demands that new hardware and software be developed to meet the needs of the electronic workgroup - which raises issues of human-machine interface. Further, it raises the key issues of how to represent and expose knowledge to users in intelligent information - sharing systems, designed to include not only good user interfaces for supporting problem-solving activities of individuals, but also good organizational interfaces for supporting the problem-solving activities of groups. The paper closes by charting promising directions for further research and with a few remarks about the computerized design firm's (near) future.

title	Intuition & Computer Visualization in an Urban Design Studio
doi	https://doi.org/10.52842/conf.ecaade.1989.x.i5v
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
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	The structure and function of diagrams in environmental design :a computational inquiry
source	Massachusetts Institute of Technology
summary	The design process often begins with a graphical description of the proposed device or system and sketching is the physical expression of the design engineer's thinking process. Computer Aided Design is a technique in which man and machine are blended into a problem solving team, intimately coupling the best characteristics of each. Solid modelling is developed to act as the common medium between man and the computer. At present it is achieved mainly by designing with volumes and hence does not leave much room for sketching input, the traditional physical expression of the thinking process of the design engineer. This thesis describes a method of accepting isometric free hand sketching as the input to a solid model. The design engineer is allowed to make a sketch on top of a digitizer indicating (i) visible lines; (ii) hidden lines; (iii) construction lines; (iv) centre lines; (v) erased lines; and (vi) redundant lines as the input. The computer then processes this sketch by identifying the line segments, fitting the best possible lines, removing the erased lines, ignoring the redundant lines and finally merging the hidden lines and visible lines to form the lines in the solid in an interactive manner. The program then uses these lines and the information about the three dimensional origin of the object and produces three dimensional information such as the faces, loops, holes, rings, edges and vertices which are sufficient to build a solid model. This is achieved in the following manner. The points in the sketch are first written into a file. The computer than reads this file, breaks the group of points into sub-groups belonging to individual line segments, fits the best lines and identify the vertices in two dimensions. These improved lines in two dimensions are then merged to form the lines and vertices in the solid. These lines are then used together with the three dimensional origin (or any other point) to produce the wireframe model in three dimensions. The loops in the wireframe models are then identified and surface equations are fitted to these loops. Finally all the necessary inputs to build a B-rep solid model are produced.

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

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.

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
