title The Changing Image of the City
source University of Utrecht
summary The image and structure of a town are constantly subject to a dynamic process of change and continuity. Visual material, such as photographs, historical maps, town plans, drawings and prints, show us the impact of these changes on the image of a town. The main point of departure of this study stems from the question of how this process of change and continuity is visually detectable in a town or city. The fact that the ideas about the appearance of a city (gradually) change, can be read from the often subtle changes in the townscape. Though in many cases we have a general knowledge of the choices made in urban management, the most difficult problem is to detect the underlying decisions. This raises the question to what extent these changes and also the continuities are the result of deliberate choices in urban management and to what extent they are autonomous developments in the townscape resistant to interventions. Using different kinds of visual information as a basis, computer visualization techniques are used in the present study to examine some cartographic maps and to reconstruct the urban development in the twentieth century of the town of Heusden three-dimensionally in significant phases. The resulting visualization provides us with a tool for a better understanding of the dynamics of urban transformation processes, typologies and morphological changes and continuities.

summary The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are to check design compliance with the requirements of local planning authorities; characteristics evaluated will include building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. In addition to the common graphical output; i.c. plans, elevations and three dimensional models, it will generate textual analysis in report format to use as part of the Environmental Impact Analysis of proposed development. The tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out with architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of data for environmental statements. Second, field observation and participation will be carried out to observe decision-makers behaviour during assessment of building design proposals. A prototype is currently under development and will be tested against the expectations of the tool designer, Ashraf Ismail, and a team of professionals to be involved in the field studies. A critical analysis of the prototype design methodology and the study findings will be documented in the research thesis to be presented in June 1995.

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 Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title Leading Indicators of CAD Experience
source CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 313-334
summary Current interfaces and help facilities of CAD systems are not designed to respond to a user's performance. To develop such adaptive environments, a better understanding of the indicators of CAD experience is required. This paper discusses the results of studying behavior patterns of different types and levels of CAD users for a specific drawing task. The results show that the type and experience of the CAD user has a clear correlation to the pattern of commands used, the time taken, and the quality of drawing produced. By using the experimental data to train a neural network, the paper demonstrates a connectionist approach for experience assessment. This information, it is proposed, can provide input to an adaptive interface which generates unobtrusive interception to improve the performance of a CAD user. Future experiments to explore the issues of generality and interception are presented.

summary What happens during an architect’s search for the best solution? How does he (or she) begin, which tools are chosen, what happens when he comes to a standstill? The activities – sketching, discussions with other people, making models, taking walks to think, visits to the library, etc? What is an ordinary procedure and what is more specific? Do the tools have an impact on the final solution chosen? What happens during periods of no activity? Are they important? In which fields of activities are signs of the searching process to be found? In other words — what is the process of creative thinking for architects? Mikael Hedin and myself at Design Methods, Chalmers University of Technology, have started research into architects’ problem-solving. We have finished a pilot study on a very experienced architect working traditionally, without Cad (”The Bo Cederlöf Case”). We have started preliminary discussions with our second ”Case”, an architect in another situation, who has been working for many years with Cad equipment (Gert Wingårdh). For our next case, we will study a third situation – two or more architects who share the responsibility for the solution and where the searching is a consequence of a dialogue between equal partners. At present, we are preparing a report on theories in and methods for Searching and Creativity. I will give you some results of our work up till now, in the form of ten hypotheses on the searching process. Finally, I would like to present those fields of activity where we have so far found signs of searching. Our approach, in comparison with earlier investigations into searching (the most respected being Arnheim’s study on Picasso’s completion of the Guernica) is to collect and observe signs of searching during the process, not afterwards. We are, to use a metaphor, following in the footsteps of the hunter, recording the path he chooses, what marks he makes, what tools, implements and equipment he uses. For practising architects: a better understanding of what is going on and encouragement to try new ways of searching, for architectural students: better preparation and training for problem solving. It all began while we compared the different objects in our collection of sketches at the Chalmers STUDIO for Visualisation and Communication. (For some years, we have been gathering sketches by Alvar Aalto, Jorn Utzon, Ralph Erskine, Erik and Tore Ahlsén, Lewerenz, Nyrén, Lindroos, Wingårdh and others in a permanent exhibition). We observed similarities in these sketches which allowed us to frame ten hypotheses about the searching process.

title Exploring Structural Morphology Using CAD
doi https://doi.org/10.52842/conf.ecaade.1993.x.d1k
source [eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary Often in the design process the student's imagination is restricted by their inability to visualise, model or accurately sketch ideas for innovative structural systems. By using CAD as a design tool it is possible to explore the morphology of complex structures and to be able to produce perspective drawings of them with relative ease. Within AutoCAD there is a small library of standard three-dimensional objects and surfaces that can be called upon to generate more complex forms. However, to further facilitate the architectural design process, an extended library of innovative structural forms would allow the professional designer, or student, greater design freedom and any increase in the palette of structural forms available should stimulate creativity. As practical examples, the paper describes how students have been encouraged to experiment with the use of structures which can only be physically modelled with difficulty and which are also difficult to represent on the two- dimensional surface of the drawing board unless the geometry has previously been determined by the methods described. These are (i) Reciprocal Frame three-dimensional beam grillage structures and (ii) plate domes created from lattice structures by point-to- plane duality. The problem, of representation of these structures has been overcome, in the first case, by generating AutoLISP procedures to draw the complex three-dimensional geometrical form automatically in AutoCAD and, in the second case, by the development of the computer program CADual.

title A Computer-Assisted Diagramming System
source Swiss Federal Institute of Technology, ETH Zurich
summary This research investigates characteristics and generation of graphic diagrams used in support of analysis, presentation and synthesis of information in various domains. The research is aimed at the development of a software system which can be used to specify, generate and manipulate diagrams similar to the way they are represented and operated upon in traditional media.Diagrams are graphic representations of symbolic propositions that allow tentative reasoning and inferencing, and enable a person to focus on selected aspects of a situation that are deemed of interest. The economy and directness of expression found in diagrams seem to be the prime reasons why they are so ubiquitous in many domains. Despite these advantages, studies into supporting diagrammatic representations using computers are rather sparse. This research is an attempt at developing a comprehensive framework of thought in this direction.In the context of design disciplines like architecture, this research forms a part of the continuum of studies in computer aided design techniques and tools. While a large number of tools and techniques in CAD have emerged so far, usage of such tools, due to their underlying representations, expects and demands commitment of too many details too early in the design process. This research is aimed at characterizing and developing a computer based diagramming system to support tentative reasoning using diagrams, and thus hopes to extend the scope of CAD environments in design. The thesis first articulates motivations for this topic in detail. Next, a discussion on the role played by diagrams as conceptual tools in various domains is presented. It is followed by a detailed look at characteristics and components of diagrams viewed as a graphic communication system. Next, a comprehensive set of requirements for an ideal software environment for diagramming tasks is developed. A prototype system called CDT was implemented and is used to demonstrate ideas developed in this research. The study concludes with some observations on contributions of this research effort and possible future extensions.

summary This paper describes the development of a computer- based diagramming tool (CDT) that supports incremental structuring of problem information using diagrammatic representations. Diagrams as graphic representations of symbolic propositions allow tentative reasoning and inferencing. The development of CDT has been carried out based on two observations. First, many diagrams are used to represent objects and relations between them. Second, diagrams comprise graphic Symbols arranged on a plane using topological and geometric relations to denote problem relevant information. CDT responds to these needs by incorporating a number of computational ideas: graphic interface, direct manipulation, constraint representation by demonstration, and specification and satisfaction of diagram composition rules.

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 In the proceedings of the first EAEA conference, 1993, I mentioned our first study focused on refining endoscopic video images of a detailed architectural model and drawings. The study was based on work with 900 subjects, of which 200 were professional architects. It has led to a number of technical improvements. In the second study we compared computer-aided design techniques with two techniques from the first study, endoscopic video recordings and coloured and black and white elevations and perspective drawings. Four different groups of 50 subjects took part in this research. We found that computer images are invariably judged to be of moderate value, while drawings yielded consistently high scores. Endoscopic video recordings of the scale model received high scores as far as emotional response is concerned, and moderate scores when the participants were questioned on the actual content of the recordings.

source [eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary CAD, in its usually available forms, is wonderful at illustrating proposed architectural objects. But, as I argued last year at the Barcelona meeting, it is not so good at helping us extend the richness and development of architectural ideas—at the "back of envelope" and other developmental Ievels—indeed, it is (for pragmatic reasons—and others) actually restrictive of change, what-if, suck-it-and-see, etc. I shall describe a work environment, which we have been developing since last year in Portsmouth, in which computing is used by students to assist the generation, testing and extension of ideas: in which exploring takes precedence over illustrating. The central notion of this environment involves the extension and manipulation, through co-operative sharing of a joint "resource base" of computer stored images (recognising origination rather than ownership), and (parts of) which may be copied and transformed by group members as they seek to develop, enrich and extend their ideas. Transformations may be intentional, but some occur through the limits of our computational medium such as compression losses, file formats, colour depth and resolution and are welcomed as a contribution made by the computing medium used. Images are located through a developing, shared filing system, picture search and history trace. The environment relies on a small suite of computers wile a powerful machine acting as a fileserver and undertaking central, computationally-intensive tasks. For this environment, we have chosen software carefully, and the choice will be described. We have also developed a small, but crucial program that traces developments in the shared resource base—in what is, in effect, our own, operational CyberSpace (as distinct from a Virtual Reality). Through these mechanisms, we believe we are able to evade the limitation set by Ross Ashby's "Law of Requisite Variety", thus expanding the creativity-base of participating designers (students). There are no "scientific results", but we believe the reasoning behind, and the activity and exploration of our environment is valuable in itself, and may be of interest to collegues.

title Looking into Endoscopy - The Limitations of Evaluation in Architectural Design

summary The means available to architects in their age-old task of creating (most usually, though not necessarily) buildings that do not yet exist (ie. virtual realities), can be seen as falling into two groups. Those that help us develop architectural ideas (exploring), and those that help us evaluate or test them (illustrating). In the former category, we have, for instance, the ”drawing on the back of the envelope”, the discursive brainstorm, and the design ”conversation with ourselves via paper and pencil” (the drawing strikes back). In the latter, we may include physical model building, careful (projective) drawing (including drawings that are instructions for making), mathematical and design science modelling and calculating, visualising techniques such as the rendered perspective, most CAD (computer aided design) work and architectural endoscopy. These techniques may be thought of in two ways, as Bosselman reported: the explanation (eg. the organisational plan) and the experience (eg the ”photo-realistic” perspective). Attached to these we have rules for success, such as those of ”style” (in the broad sense of the personal style that allows us to assume that we have answers to problems that have yet to appear). It should be clear even from the list above that there are many more techniques and technologies for evaluation (illustration) than for exploration (design): such is the mystery of design. It is the primary purpose of this paper to invite those involved in providing the enormous effort that has gone into making such techniques for illustration — evaluation — to consider how their efforts help with that other, and crucial, area — that of exploring: and to redress some of the balance of that effort towards exploration. For it occurs to me (as a teacher of architecture), that evaluation does not provide a course for action — it merely helps us determine what may be wrong (according to some criteria with which we choose not to argue). And, no matter how right or wrong a design may be, knowing that it is wrong doesn’t help us either modify it, or find a better initial idea. It only tells us we are not right — always assuming the evaluative model is correct; perhaps.

summary A study was undertaken of the application of computer visualisation to the control of design by local planning authorities in England. Several examples of major urban development and routine development control work were visualised for local councils, the images fed back into the decision-making process, and the results monitored. While the investigation of the decision-making process is still continuing, the results obtained to date demonstrate an important role for visualisation. The work undertaken is described and comment is made on both the pattern of possible use by a planning authority and the general issue of the objectivity of the images.

summary Presently, only a small percentage of people in the world typically hire an architect to design and build a home which is tailored to their preference. Besides the architect’s fee, clients also need to wait an interminable time for design and construction. Factory-made prefabricated housing systems tried to solve this problem previously. However, most pioneers failed to address the issues of variability and individual needs (Kieran & Timberlake, 2004). Plants closed because they produced more than the market demand, and prefabricated housing provided less flexibility than the traditional stick-built housing. The advanced digital technology makes it possible to communicate design ideas and concepts to others more effectively. The project delivery process leads itself to customization, embodying principles of lean production (Pine, 1993), flexible computer-integrated design interaction with clients, and reduced cycle times; all effecting rapid response between consumers and producers.

summary In idea sketches, there are a number of ambiguous shapes. Designers will associate and transform some shapes into others (Liu, 1993). Then, they evaluate these shapes in terms of functions and design requirements; furthermore, they would have generated other shapes that certified the design requirements (Huang, 1999). However, not only is the idea of design composed of one element, but also consisted of varied components. The purpose of this paper is to investigate how designers generate ideas of multi-component products, and to simulate this phenomenon by neural networks. At the same time, this paper attempts to study the design cognitive behavior of idea-generating stages, and explores the designers' cognitive phenomenon. Therefore, there are two stages in this paper: First, I conduct a cognitive experiment to realize how designers generate the multi-component product and acquire the sketches that designers generated. Second, I train the neural networks to simulate the behavior of idea generation and explore the cognitive phenomenon in design sketches. As a result, networks associate one shape that trained before, and then generate a complete idea. This phenomenon is similar to the cognitive behavior of designers who saw the ambiguous shape as one shape, which was retrieved from LTM. Moreover, the neural network is examined by a rectangle, which is totally different from the training patterns. The network will associate a confused shape. But the network will associate different shapes by adjusting some critical parameters. Designers can generate variable shapes from one shape, but the signal neural network can't simulate this kind of behavior. On the contrary, this paper proposes five sequential networks to generate variable shapes from the same shape and simulates how designers develop ideas.

summary The main objective of this paper is to explain the process of knowledge acquisition utilising the method for the decomposition of the components of a system to extract design rules. The furnished drawing of a dwelling is considered as the language of a designer. These drawings contain the semantic knowledge that can be called general architectural know-how. This paper bases on the decomposition of the syntax of a room image. The syntax of a room image consists of walls, windows, circulation zones and furniture such as beds, wardrobes, commodes, dressing tables, etc. The syntax of a room image has some linkages. The designer put the syntax together with the joints of circulation zones as a grammar to match. The existing relations between the objects in a design can be called grammar. An experiment is applied to three classes of a CAAD course organised by the Turkish Chamber of Architects. The living room is given already furnished in the experiment and the rest of a dwelling is expected to be furnished. In the first phase, the experiment is applied on two different classes in different times. It is interesting that the same grammar is used by 6 of 8 couple of designers for 3 different types (A, B and D) of bedrooms. Only one of the bedrooms of C type) has different design styles in spite of looking much like each other. In the second phase, for the third class of 6 groups, plan is modified slightly. In this case all of the 6 couples of designers use the same grammar for 2 alternatives of D type bedroom for parents. An original method is applied in the elicitation of the knowledge in this experiment. The properties of the objects and their links are represented by a semantic network graph. This paper also presents the grammar of the furnished rooms and shows the density of preferences. Design rules are extracted from these drawings of a furnished dwelling by searching for similarities in the plans designed by different designers. The designers have some specifications about the grammar of furnishing and an image schema of the proposed room in their minds, depending on their education and experiences. During the design of a room, designers look for differences and the similarities existing in the syntax of the proposed room image and the image of furnished room on the screen. If these images match with each other, the designers satisfy with the result This paper investigates the image schemata of the designers by evaluating their drawings. Some design rules are represented by means of image schemata. Matching the joints of circulation zones, the designers put the syntax of different image schemata together and they can illustrate different alternatives, restricted by the translation of these image schemata.
