title	Computer Integrated Design: Transformation as Process

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	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	Creativity in Design Using a Prototype Approach
source	Design Computing Unit, Department of Architectural and Design Science, University of Sydney, 1989. pp. 207-232. CADLINE has abstract only
summary	This paper discusses creative design as the creation of new syntax in response to required semantics. Various ways of producing creative designs are investigated and it is postulated that the key element in all of these is experience. The paper stresses the need to provide a schema whereby experiences are generalized and stored as concepts wherein syntax and semantics are associated, the prototype schema is seen as providing a suitable structure

title	What Designers Do That Computers Should
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. 17-30
summary	Designers do many things that computers don't. Some of these are bad habits that the stringencies of computation will correct. But others are basic to design, and cannot be ignored if computation is to serve creation and invention. Two of these provide the correlative themes of this paper. Both are concerned with description, and its variability and multiplicity in design.

title	Hypertext: A Computer Tool to Assist Building 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. 283-300
summary	This paper shows how hypertext, an electronic information transfer medium, can assist accessing the large volumes of architectural and engineering technical information needed in decision-making phase of building design. A technical paper on architectural details serves as a model for demonstrating the capabilities of hypertext. This example consists mostly of graphics and illustrates how the hypertext medium could act as an information source for designers in the construction industry. The objectives of the paper are to illustrate the potential of hypertext to create, disseminate, and access technical information, and to identify an electronic format for construction industry technical publications. The paper identifies the capabilities of the medium, some advantages and disadvantages of hypertext, and the potential of the medium for construction information transfer. The author suggests that hypertext systems can assist technical information transfer in the construction industry.

title	Interactive Animation on the Macintosh II
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 9.5.1-9.5.6
doi	https://doi.org/10.52842/conf.ecaade.1989.x.a0t
summary	The efficiency of images in communication between humans has so far been used almost exclusively by TV and other mass medias. The costs have been too great to encourage the use of images in the financially restricted everyday practice of architecture. With a range of application programs for the Apple Macintosh II the vision has come close to reality. It is now possible to create guided walks with the chance to choose different routes and views in a model of buildings and surroundings in 256 colour graphics. The makers of these programs may not have foreseen this use for their products and that is why it takes quite a lot of effort to make all the necessary images. With some supplementary routines however, this will be made much easier. Animation can also be used to visualize different processes inside a building. We have been studying the working environment in mechanical industry. The goal of this project is to make communication possible between the workers at all levels of an organization in planning changes and has so far been very successful. The use of this technique is only limited by our imagination and funding. Some examples to be tested in the near future are "Escape at a fire", "Animation of a Dairy", "Traffic situations in a parking lot-, "CAD-working place" and others. One of the difficulties in interactive planning with users has been to come close enough to their reality. With animated images it is possible to visualize what is going to happen and what it is going to look like in a more understandable way. In education this must be a challenging possibility. Changes and processes are some of the most difficult subjects to describe and explain! The software used is a handful of individual programs which, thanks to the graphics standards of the Macintosh, can exchange data with each other.

doi	https://doi.org/10.52842/conf.ecaade.1989
summary	In the announcement of the sixth eCAADe Conference we stated that It is held at a time where CAAD is moving into practice very fast, with heavy influence on research and education. We stated that research is directed towards the early design phases, and that education is facing the problem of mass education. In that situation much benefit can be obtained from collaboration with practice. We decided to give the conference the title “CAAD: Education - Research and Practice” to state the importance of practice as a test bench. The conference papers cover education and research in depth in many important areas and give a good overview, whereas the practical theme is more or less missing, indicating, that experience here is still modest. At the lecture material market and the exhibition the situation is opposite and shows state of art in practical use.

title	Computational Design Instruction: Toward a Pedagogy

summary	The computer offers enormous potential both in and out of the classroom that is realized only in limited ways through the applications available to us today. In the early days of the computer it was generally argued that it would replace the architect. When this idea became obsolete, the prevailing opinion of proponents and opponents alike shifted to the notion of the computer as merely adding to present design capabilities. This idea is so ingrained in our thinking that we still speak of "aiding" design with computers. It is clear to those who grasp the real potential of this still new technology - as in the case of many other major technological innovations - that it continues to change the way we design, rather than to merely augment or replace human designers. In the classroom the computer has the potential to radically change three fundamental ingredients: student, instruction, and instructor. It is obvious that changes of this kind spell out a commensurate change in design pedagogy. If the computer is going to be more than a passive instrument in the design studio, then design pedagogy will have to be changed, fundamentally. While the practice of computing in the studio continues to be a significant I aspect of architectural education, articulation of viable pedagogy for use in the design studio is truly rare. In this paper the question of pedagogy in the CAD studio will be considered first. Then one particular design studio taught during Fall 1988 at Carnegie Mellon University will be presented. Finally, we shall return to issues of change in the student, instruction, and instructor, as highlighted by this particular experience.

summary	DOOTERS is a to-do list application for iPhone which entertains and motivates the user to get things done. It was developed based on requirements obtained trough: 1. the study of several personal information organizing methods (Covey, 1989; Allen, 2005; Foster, 2006); 2. answers to a task lists user focused questionnaire; 3. observation of to-do list users while creating lists and organizing tasks; 4. comparison of digital and non-digital task list media (paper, computer and mobile device); 5. analysis of profiles, behaviors and to-do list applications for iPhone. In this paper, the authors present the process of obtaining requirements for developing and positioning DOOTERS.

summary	Should we teach CAAD? - yes, but why? Answer to this question is clear too. Question three - "when?" - on the 5, 6 and 7 term. Why so rate? - it is a compromise because "Architecture is an art" and students of architecture should know how to make a project without computers. How to teach CAAD? - we should teach haw to use professional computer programs and not programming. We must work out a new manual for architects. It should be constructed in such a way as to correspond to consecutive steps of the architectural design process.

source	17 p. : ill Engineering Design Research Center, CMU, October, 1989. EDRC 24-10-89. includes bibliography.
summary	Simple s-plane maps are used to graphically reveal interactions of performance requirements and constraints thus providing a control system designer insight into performance trade-offs. Two well-known but powerful ideas underlie this approach: (a) the characteristic equation of an nth-order system can be fully described by the specification of n variables and (b) any dynamic performance requirement or constraint can be expressed in terms of 2n variables of which n describe the open-loop and n describe the closed-loop characteristic equations. An example illustrates the application of the approach to controller design

summary	In this paper the author will consider four key concepts: design, evaluation, models, and representation. In combination, definitions of these concepts impinge on each other and they are further conditioned by the author intention to represent design knowledge within computers. The issue of human-computer interaction then becomes critical to the usefulness of knowledge representations for designers

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

title	Modeling Architectural Forms through Replacement Operations
source	New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 103-130
doi	https://doi.org/10.52842/conf.acadia.1989.103
summary	Replacement operations, where an element at any topological level may be replaced by another element at the same or different topological level, are defined. Their potential as design tools which may be incorporated in a CAD system is investigated and demonstrated through the experimental implementation of two such operations in MARCOS, a Modeling Architectural Compositions System. MARCOS has been written in C. It is highly interactive and runs on an Apple Macintosh IIx. The two operations which have been implemented are the face -> volume and volume -> volume replacements. They were chosen for their potential as generators of architectural forms. Examples of architectural compositions produced through the use of replacement operations are also illustrated.
