title	Behavior Modeling in Design System Development
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 335-354
summary	We describe the development approach for a software environment to support the early phases in building design called SEED. The combination of capabilities offered by SEED to designers is novel and includes the integrated handling of solution prototypes. We give the reasons for using an object-oriented software engineering approach in the development of the system, which starts with a comprehensive behavioral model of the system from the user's perspective based on actors and use cases. We illustrate results from the first development phase and sketch the next phases. At the time of the CAAD Futures '93 conference, we will be able to report our experience in developing a first system prototype and to demonstrate the prototype.

title	Case-Based Structural Design - using weakly structured product and process information
source	Chalmers University of Technology, Division of Steel and Timber Structures, Publ. S 00:7, Göteborg
summary	Empirical knowledge plays a significant role in the human reasoning process. Previous experiences help in understanding new situations and in finding solutions to new problems. Experience is used when performing different tasks, both those of routine character and those that require specific skill. This is also the case for structural designers. Over 50% of the work done by the designer on a day-to-day basis is routine design that consists of modifying past designs (Moore 1993). That is, most of the design problems that the designer solves have been solved before, in many cases over and over again. In recent years, researchers have started to study if cases (information about specific problem-solving experiences) could be used as a representation of experiential knowledge. Making use of past experience in the form of cases is commonly known as Case-Based Reasoning (CBR). A requirement for Case-Based Design (Case-Based Reasoning applied in design) to be successful is that the design information is computerized. One information type used in structural design that is starting to become computerized is the one in design calculation documents. Such information is weakly structured (which holds for much of the information representing experience) and it contains both product and process information. In this thesis it is shown how the weak structure of this information can be used to subdivide it into components, which in turn makes it possible to apply the object-oriented abstraction principles also to this kind of information. It is also shown how the detailed design process can be represented and how this representation can facilitate automatic acquisition, retrieval of relevant old design information, and adaptation of this information. Two prototypes BridgeBase and ARCADE have been developed, where the principles described above are applied. Using ARCADE, the more general of these two prototypes, it is presented how information in computerized design calculation documents, gathered from real projects, can serve as containers and carriers for both project information and experience. The experience from the two prototypes shows that Case-Based Design can be usable as a tool for structural engineers.

title	PLASM Functional Approach to Design: Representation of Geometry
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 127-141
summary	PLASM (the Programming Language for Solid Modeling) is a solid-modeling-oriented design language strongly inspired by the functional language FL. In a PLASM environment, every geometrical object is generated by evaluating a suitable language expression which produces a polyhedral solid model. The language adopts a dimension-independent approach to geometry representation and algorithms. The generated objects are always geometrically consistent since the validity of geometry is guaranteed at a syntactical level. In fact (a) each well-formed expression is obtained by proper composition of well-formed subexpressions; (b) the evaluation of a well-formed (and polyhedrally typed) expression produces a valid solid model. In this paper, the representation scheme used in the language is given and some language scripts are shown and discussed.

title	A Hierarchical Model for Building Applications
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 423-435
summary	Advanced computer-aided architectural applications must model buildings as multi-level compositions supporting distinct points of view. Hierarchies of encapsulated, autonomous elements can be derived from ISO-STEP's General AEC Reference Model and configured for various applications. For analysis of life-cycle costs, we define a Pyramid of evaluable production steps leading to the final building; for optimization of renovation task schedules, a topological model of access paths and traffic flow. These separate viewpoints can be embedded in a single unifying structure permitting the communication and propagation of changes among its specialized aspects.

title	Modular building models
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The development and implementation of a modular building model appropriate for computer aided design is described. The limitations of a unified building model with regard to concurrence and complexity in design is discussed. Current research suggests that to model real-world complexity, one must trade centralized control for autonomy. In this paper we develop a modular approach to building modelling that is based on object-oriented autonomy and makes it possible to define these models in a distributed concurrent manner. Such a modular and autonomous implementation brings inherent uncertainty and conflict which cannot be determined a priori.

title	Analogy, Exploration and Generalization: Three Activities for Knowledge-Based Architectural Design Systems
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 255-272
summary	We propose in this article a system architecture based on reasoning through analogy with past cases or situations. Starting with a project and a sketch provided by the user, the system locates analogous situations in the past and uses these to improve a problem's description. A sufficiently improved description will in turn activate a constraint-satisfaction mechanism. Previous situations are stored in a memory bank of objects that match the description of past problems to the generic descriptions of past solutions. Three mechanisms can be distinguished within the system: an analogy mechanism collects hypotheses about the variables and constraints to be satisfied in past situations, an exploratory mechanism searches through the solution space, a generalizing mechanism looks at experiences and memorizes only what is needed to collect hypotheses.

title	Representation of multiple concepts of a design object based on multiple functions
source	K. Mathur, M. Betts and K. W. Tham (eds), Management of Information Technology for Construction, World Scientific, Singapore, pp. 239-254
summary	Current representatuin schemas for design objects in CAD environments make assumptions regarding particular representations of the design object. In the AEC environemnt, many disciplines are involved, each with its own concept of the design object. Each such concept must be respected and accomodated in any representation. This paper presents the ideas behind the representation of multiple concepts from an underlying description of a design such that the inter and intra-discipline views of that design can be formed dynamically.

source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 289-309
summary	The paper presents computer reconstructions of unbuilt projects relevant to the history of Italian rationalism together with the potential and limits of three CAAD environments. While an evaluation is provided for each one, a more detailed attention is devoted to hierarchical structures because of their capability to capture knowledge, to support further investigations, and to provide new insights into architecture. A model built in this environment allows simultaneously (1) the analysis and reconstruction even of a complex project at the size of a personal computer; (2) the simulation and test of different material, crucial in the case of restoration or in the case of incomplete and uncertain original project data; (3) the critical analysis (but also the co-presence of the different project alternatives of design phases) through the reading at the various level of the hierarchy; and (4) free investigation on the structure of data that can support new critical hypothesis and insights that were not anticipated at the moment of project creation.

title	3D Computer graphics
source	Addison-Wesley, pp, 1-13
summary	The third edition of Alan Watt's 3D Computer Graphics, a bible of computer graphics, includes a CD-ROM full of examples and updated information on graphics and rendering algorithms. The book discusses many of the techniques that have evolved in the seven years since the previous edition was published. 3D Computer Graphics is a textbook, and it's designed for serious programmers creating graphics applications (not end users). Over the course of 16 sections, Watt introduces the concepts and implementation of computer imaging, from "Mathematical Fundamentals of Computer Graphics" to "Representation and Rendering" and ending with "Image-Based Rendering and Photo-Modeling." The last section, devoted to computer animation, includes methods for linked structures, collision detection, and particle animation (to name a few). Although the topics are sometimes hard to grasp, Mr. Watt writes clearly and concisely, making generous use of diagrams to help convey the principles described in the text. The accompanying CD-ROM includes over a dozen studies of computer graphics techniques and rendering algorithms. Presented in HTML, the exhaustive studies, each with a matrix of thumbnails, demonstrates the varied achievable results. One minor complaint here: although the thumbnails can be clicked to view a much larger image, the larger versions come in .tif format, which few (if any) Web browsers can view. Users will need another application to view them. Having the large image in .jpg format would have enabled the reader to view it in the already-open Web browser.

title	An integrated system to aid the planning of concrete structures: introducing the system
source	The Int. Journal of Construction IT1(2), pp.1-14
summary	This paper reports on the development at Loughborough University of a CAD-based integrated model to aid the planning of in-situ concrete structures. The system development started after a review of the planning models currently available and after a detailed questionnaire survey undertaken amongst the top UK and US contractors on the current status of planning techniques and information technology. The main aim of this system is to automate the planning process of in-situ concrete structures using data generated by CAD systems. So far, the integration of a CAD system (AutoCAD 10) and a computerized scheduling system (Artemis 2000) has been achieved on a typical IBM-PC. This enables the generation of network plans using AutoCAD which are then automatically transferred to the Artemis system for time and cost analyses.Traditionally, construction planners are faced with many conventional drawings and documents which are used to re-extract information relevant to their planning processes. Such an approach can be very inefficient as it involves data double-handling and is often error prone. In addition, current computerized construction planning applications are little more than the automation of manual formulations of plans. For example, data are fed into the planning system and computations are performed using either CPM (Critical Path Method) or PERT (Programme Evaluation and Review Technique). However, data relating to the planning process such as activity lists, resources requirements and durations are not automatically generated within the system. It would thus seem logical to devise a CAD-based integrated planning model which accepts data in its electronic format and involves some integration of the traditional planning approach. This paper introduces the proposed CAD-based integrated planning model and describes its different components. In addition, it discusses the system functional specifications and summarizes the main benefits and limitations of such a model.

title	A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

title	Grow: Generative Responsive Object for Web-based design - Methodology for generative design and interactive prototyping
doi	https://doi.org/10.52842/conf.ecaade.2014.2.587
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 587-594
summary	This paper is part of the research on Generative Design and is inspired by the ideas spread by the following paradigms: the Internet of Things (Auto-ID Center, 1999) and the Pervasive/Ubiquitous Computing (Weiser, 1993). Particularly, the research describes a number of case studies and, in detail, the experimental prototype of an interactive-design object: “Grow-1”. The general assumptions of the study are as follows: a) Developing the experimental prototype of a smart-design object (Figure 1) in terms of interaction with man, with regard to the specific conditions of the indoor environment as well as in relation to the internet/web platforms. b) Setting up a project research based on the principles of Generative Design.c) Formulating and adopting a methodology where computational design techniques and interactive prototyping ones converge, in line with the principles spread by the new paradigms like the Internet of Things.

summary	Simulating the development and the image of architecture and urban design means to show how the environment of the future and the living conditions could develop. At the same time it is part of our task to explain our work to local people and to the public and to passion skills in methods, instruments and knowledge in planning to the next generation of architects, planners and last but not least to discuss and to renew them once more for ourselves. Our aim was also to reflect what we have done since starting the look through the key-hole of endoscopy. Meanwhile this look has been completed since the beginnings in 1993 much more by computer and monitor. It is not the question to take the endoscope or the computer as a methodical and instrumental approach. Nowadays we normally decide to take the endoscope and the computer. In preparing the conference and the workshop we thought that this should now also be the moment not only to inform each other and the participants on methods, tools and best practices in simulating and designing the environment but also to focus on the social and human consequences of perception, movement and use the present urban spaces and the urban space in future. So we proposed the theme “MOTION, E-MOTION and URBAN SPACE” and we invited a scientific expert in experimental psychology to give us some serious reflections and one or another hint on our research themes and methods. The contributions and discussions in the conference showed that the proposal has not only been accepted but has also been completed and enriched especially concerning the theme urban space, it’s processes of usage and it‘s atmosphere. Also in the themes of endoscopy and the research on modelling urban spaces and architecture, meanwhile nearly “traditional” ones, remarkable results were presented and discussed. A very important point of contributions and the following discussions was how to present our subjects to the interested public and to improve our own internal exchange. An object could be to enforce the research tasks in researching together even more.

source	Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 11-20
summary	What do young architects need to know about computer graphics? What "immutable and eternal" models will allow them to perform their best as professional architects? At one time all computer users were computer programmers and the answer was thus rooted in programming expertise, but the era of personally developed software is largely past. An alternative more vocational approach would stress courses in the use of specific programs, but it is hard to imagine a more mutable "object of knowledge" than the practical details of computing in the late twentieth century. In fact, our students are deluged with information: commands, vocabulary, options, sales hyperbole, and "do this, it works" cookbooks. As educators, we face the challenge of identifying that which is "immutable and eternal", and presenting it to our students (and trying to focus their attention on it).

title	Geometric Relations as a Framework For Design Conceptualization
source	Harvard University, Graduate School of Design
summary	This study introduces geometric relations as a framework for design conceptualiza-tion-its key premise is that nothing is more fundamental in design than formation and discovery of relationships. The study attempts to establish a formal model for the development of a dynamic computer based graphic environment for design conceptualization that can recognize, record and maintain geometric design relations, merge "depictive" and "propositional", explicit and implicit in design, and provide a qualitatively different way to explore shape, dimension, and geometric organization. The study presents an approach to this task of formalization, and explores some of the fundamental issues pertinent to the subject, such as computability and applicability to the task of designing.Specifically, the study explores a relational description of shapes based on the concept of regulating or construction lines as an explicit formulation of a strategy to form generation and creative discovery, and proposes a lexicon of geometric relations to serve as a basis for composition. It hypothesizes that the construction lines can become much more useful and interesting when they are used not just as a rigid skeleton, but to regulate the behavior of a drawing and to maintain its essential structure as its parts are manipulated. As a consequence, designers could structure the behavior of the object being designed under future transformations; drawings could become seman-tically charged and could be manipulated in a semantically sophisticated fashion.The first chapter places the issue in the broader context by arguing that designers form implicit relational models of their designs. This contention is supported by introducing some of the relevant literature on mental imagery. Second chapter introduces design relations and in particular geometric relations, as a focal point of this study. A dynamic computer -based graphic context for design conceptualization is presented and evalu-ated in the next two chapters and conclusions are drawn. In the third chapter, the model's computability is demonstrated and evaluated through ReDRAW, a limited implementation of a relations based graphic system. In the fourth chapter, the model's applicability in design conceptualization is discussed and supported by examples.

summary	The basic point of our conception is not to submit the architect to technical means, but give him freedom of choice and the opportunity to work in the environment closest to the real one. In our situation it means, that we should provide work in real videoinformative space. Thus, our conception of education is to give all the junior students compulsory general information about videosimulation, and to ensure optional more professional work of undergraduates while carrying out their school projects. We consider, that in the architect’s activity simulation (making small-scale models) plays an essential part, because the small-scale model is the first and the only source of true three-dimensional information about the object designed. At the same time videosimulation does not deny or substitute computer-aided design. To get reliable visual information from the model is possible with the help of special technical means equipped with periscopic devices. In Moscow Institute of Architecture this work has been carried out for 10 years.

title	CAADidactics - An Instrument for Tuning CAAD Systems to Student Styles
doi	https://doi.org/10.52842/conf.ecaade.1993.x.j4l
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	This paper discusses the features of an instrument for tuning CAAD systems to student styles implemented in the authoring shell Authorware Professional (1989). This application enables students and teachers to evaluate the design progress. It also makes it possible to assess their preferences with respect to their working styles (Subject style) and style preferences in terms of the product style (Object style) in different stages of the design curriculum. The availability of this information enables teachers to adapt their didactical approach to their students. The progress they make during design education can be evaluated by looking at the process documentation as well as by looking at the product documentation generated by the application. This makes the students conscious of their own preferences and affinities. It is up to the student and the teacher whether they want to enhance or compensate those preoccupations. The documented information of previous design sessions can also be used as a guide system for further development and adaptations in styles of design and designing. In the design studio this style knowledge can also be used to establish adequate and workable design teams. Some of the features discussed in this paper are already implemented in a small prototype application. The prototype application will be presented and discussed. Other features will be implemented in the near future.

title	Applying Visual Design: Trade Secrets for Elegant Interfaces Tutorials
source	Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems -- Adjunct Proceedings 1993 p. 230
summary	Objective: This tutorial is designed to increase the participant's awareness of visual and aesthetic issues and provide practical techniques (not guidelines) for achieving elegant user interfaces, information displays, and data visualisations. The emphasis is on avoiding a number of mistakes seen repeatedly in commercial products. Content: This tutorial will focus on the core competencies or "tricks of the trade" that all visual designers internalise as part of their basic training. The tutorial is organised not along the traditional graphic design specialisations, such as typography or colour, but according to the design goals and familiar problems of real-world product development. Specific content areas will include elegance and simplicity; scale, contrast and proportion; organisation and visual structure; module and programme; image and representation; and style. The communication-oriented design aesthetic seen in graphic design, industrial design, and architecture can be applied very successfully to graphical user interfaces, data displays, and multimedia. Design rules provided will be illustrated with extensive visual examples drawn from the international design communities as well as from the HCI domain.
