summary	This paper forms an update to the paper presented ar eCAADe 2003, in Graz. It is a summary of a project which aim is to suggest an alternate methodology for utilizing additive Solid Freeform Fabrication (more commonly known as Rapid Prototyping), for the conceptualization and fabrication of design and architecture. It plans to do so by establishing a methodology that is innate and a direct reflection of the additive SFF production process. The project also aims to address the seemingly divisive discrepancy between the process of digitally conceiving a design and the intrinsically somatic way we perceive it. Whereas the paper in Graz introduced the conceptual foundations and the taxonomy of the project, the aim in this years paper is to present some of the realized designs and discuss, in brief, how what has been learnt could be furthered as the project proceeds. The three designs described in more detail in the paper, all catalyzed by a specific sensory notion, would have been very difficult, if not impossible, to fabricate by any other means than additive Solid Freeform Fabrication.

summary	The conference logo is a bird’s eye view of spiral stairs that join and separate – an homage to the famous double spiral staircase in Graz, a tourist attraction of this city and a must-see for any architecturally minded visitor. Carved out of limestone, the medieval construction of the original is a daring feat of masonry as well as a symbolic gesture. The design speaks of separation and reconciliation: The paths of two people that climb the double spiral stairs separate and then meet again at each platform. The relationship between architectural design and the growing digital repertoire of tools and possibilities seems to undergo similar cycles of attraction and rejection: enthusiasm about digital innovations – whether in Virtual Reality, Augmented Reality, Energy Design, Robotic Fabrication, the many Dimensions of BIM or, as right now, in AI and Machine Learning – is typically followed by a certain disillusionment and a realization that the promises were somewhat overblown. But a turn away from these digital innovations can only be temporary. In our call for papers we refer to the first and second ‘digital turns’, a term Mario Carpo coined. Yes, it’s a bit of a pun, but you could indeed see these digital turns in our logo as well. Carpo would probably agree that design and the digital have become inseparably intertwined. While they may be circling in different directions, an innovative rejoinder is always just around the corner. The theme of the conference asked participants to re-consider the relationship between Design and the Digital. The notion of a cycle is already present in the syllable “re”. Indeed, 20 years earlier, in 2003, we held an ECAADE conference in Graz simply under the title “Digital Design” and our re-using – or is it re-cycling? – the theme can be seen as the completion of one of those cycles described above: One level up, we meet again, we’ve come full circle. The question of the relationship between Design and the Digital is still in flux, still worthy of renewed consideration. There is a historical notion implicit in the theme. To reconsider something, one needs to take a step back, to look into the past as well as into the future. Indeed, at this conference we wanted to take a longer view, something not done often enough in the fast-paced world of digital technology. Carefully considering one’s past can be a source of inspiration. In fact, the double spiral stair that inspired our conference logo also inspired many architects through the ages. Konrad Wachsmann, for example, is said to have come up with his famous Grapevine assembly system based on this double spiral stair and its intricate joinery. More recently, Rem Koolhaas deemed the double spiral staircase in Graz important enough to include a detailed model of it in his “elements of architecture” exhibition at the Venice Biennale in 2014. Our interpretation of the stair is a typically digital one, you might say. First of all: it’s a rendering of a virtual model; it only exists inside a computer. Secondly, this virtual model isn’t true to the original. Instead, it does what the digital has made so easy to do: it exaggerates. Where the original has just two spiral stairs that separate and join, our model consists of countless stairs that are joined in this way. We see only a part of the model, but the stairs appear to continue in all directions. The implication is of an endless field of spiral stairs. As the 3D model was generated with a parametric script, it would be very easy to change all parameters of it – including the number of stairs that make it up. Everyone at this conference is familiar with the concept of parametric design: it makes generating models of seemingly endless amounts of connected spiral stairs really easy. Although, of course, if we’re too literal about the term ‘endless’, generating our stair model will eventually crash even the most advanced computers. We know that, too. – That's another truth about the Digital: it makes a promise of infinity, which, in the end, it can’t keep. And even if it could: what’s the point of just adding more of the same: more variations, more options, more possible ways to get lost? Doesn’t the original double spiral staircase contain all those derivatives already? Don’t we know that ‘more’ isn’t necessarily better? In the original double spiral stair the happy end is guaranteed: the lovers’ paths meet at the top as well as when they exit the building. Therefore, the stair is also colloquially known as the Busserlstiege (the kissing stair) or the Versöhnungsstiege (reconciliation stair). In our digitally enhanced version, this outcome is no longer clear: we can choose between multiple directions at each level and we risk losing sight of the one we were with. This is also emblematic of our field of research. eCAADe was founded to promote “good practice and sharing information in relation to the use of computers in research and education in architecture and related professions” (see ecaade.org). That may have seemed a straightforward proposition forty years ago, when the association was founded. A look at the breadth and depth of research topics presented and discussed at this conference (and as a consequence in this book, for which you’re reading the editorial) shows how the field has developed over these forty years. There are sessions on Digital Design Education, on Digital Fabrication, on Virtual Reality, on Virtual Heritage, on Generative Design and Machine Learning, on Digital Cities, on Simulation and Digital Twins, on BIM, on Sustainability, on Circular Design, on Design Theory and on Digital Design Experimentations.

title	A maintenance contract for the architect's degree - Concept, materialisation and post-occupancy
source	Ebbe Harder (ed.), Writings in Architectural Education, Transactions on architectural education No 15, EAAE/AEEA, pp.134-147
summary	Today, architecture is confronted with changing concepts of time, space and place. These changes are largely induced by the advent of the information society and in turn induce the need for entirely new ways of conceiving architectural education. It is obvious, however, that architectural education does not hold absolute sway over the need for renewal, as other domains and disciplines too are confronted with the inevitable learning society: a society in which individuals, groups and companies are learning on a permanent basis. What architectural education does hold absolute sway over – or at least should be granted a patent for – is the unique way in which it used to prepare (and still prepares) its students for practice in the design studio. Therefore, instead of throwing out the design studio with the bathwater, we consider it as an outstanding lead for pursuing the learning society within the context of architecture. Furthermore, we see ICT not only as a cause of, but at the same time as an ally in this pursuit, as it allows reinforcing the studio as “espace transitoire”. To this end, we propose to literally connect the studio with the world of practice through an on-line platform constructed of concrete cases.

title	Vision, Plan and Reality
source	Aarhus: Aarhus School of Architecture, PhD Thesis
summary	How come, that there is often a gap between what is considered good urban design and the built reality of the urban environment? This is the question which the thesis aims to investigate. It has often been stated that urban development can no longer be controlled, and the reason for this has been ascribed, among other things, to the power of the market, postmodern pluralism, or simply to the increased complexity of society. Yet, to decline on the capacity of urban design to guide urban development on such accounts, is to give up on urban design altogether. Rather, if urban design is incapable of achieving what it is aiming at, something must be wrong with it. Thus, the basic argument of the thesis is, that the answer to this question must be sought within urban design itself, rather than within the context in which it operates. In order to approach the research question, the thesis is organized as a twofold investigation, consisting of both an empirical study of the practice of urban design – in the form of a detailed case study of two urban development histories – and a study of the theoretical foundations for this practice. As urban design is regarded as an interdisciplinary activity, the theoretical study is organized as a threefold investigation of urban design theory, planning theory, as well as urban theory. As urban design in practice must consider what the built environment should be like as well as how it is developed, it must include normative as well as procedural considerations. Thus, the issues of normativity and process are central to the understanding of urban design. These issues therefore constitute the foci of both the empirical and the theoretical study.

summary	The advent of the Internet has led us to believe that we live in an era of unprecedented globalization. In the field of building design, we now expect both that the local market for design services will be altered, and that many firms will take up the opportunity to pursue commissions beyond their local market. To some extent this is true, but it is instructive to recall that in the 19th century London based architectural firms and public works designers designed buildings throughout the Empire. Designing for projects beyond the local market is not new, what is new is our expectation that such a task is now fundamentally altered, made easier and more transparent, by the abundance of new communications technologies.It remains the case that working outside one’s local context is difficult and that when doing so, problems are likely to arise out of cultural differences. Distance too imposes its burdens, as the possibility to meet other members of the team face to face is reduced as the travel costs increase. This breaks down the possibilities of building informal networks among the individual designers working for the firms that are members of the design team. A re-instantiation of this informal network can only be done on the basis of a model of formal and informal communication in the design team. Many of the difficulties of collaborative work outside one’s local market are problems that have already been with us a long time. These problems arise out of the fact that buildings are designed by heterogeneous groups of people. The members of such groups must communicate with each other to share information and coordinate decisions and actions. Yet they are in different relations to the project at hand and have differing values arising out of their different backgrounds. This leads inevitably to conflict. Therefore, if we are to discuss communication and value then we must devote our attentions to conflict.

title	Fabrication of Partially Double-Curved Surfaces out of Flat Sheet Material Through a 3D Puzzle Approach
doi	https://doi.org/10.52842/conf.acadia.2003.075
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 75-83
summary	The topic of this paper is the connection of digital modeling with generative programming and rapid prototyping, to produce physical sketch surface models. The physical surface models are assembled out of developable strips connected through a puzzle-like detail. The use of programming as a design approach allows the generation of connection details that corresponds to the rules of flat sheet rapid prototyping techniques of laser cutting and water jet cutting. With numerically controlled cutting, there is no need to keep the joint detail related to manually achievable forms or to apply a standardized dimension. This paper demonstrates the possibilities of programming to generate cutting geometries that adapt to the local surface properties. The larger perspective of the research approach is the question of how to formulate and capture design intention through programming. What influence does the use of generative modeling in combination with rapid prototyping have on the design language of physical objects?

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 261-264
summary	In this paper it is argued that new digital techniques join together several skills; from CAD (Computer Aided Design), to CAE (Computer Aided Engineering), till CAM (Computer Aided Manufacturing). That assemblage of methods involves a change in the way to achieve a project. The idea comes out as result of connected actions within software-hardware tools. According to this analysis the implementation of gradients (e.g. movement, time, direction) have a significant role in shaping a multi-disciplinary approach to design; supported by simulation as way to verify and control solutions. Such innovations can settle a new way to design, in terms of vocabulary, grammar and syntax? How can we develop useful tools to express the ""new visible"" of avant-garde techniques?

title	TAP - The Architectural Playground: A C++ Framework for Scalable Distributed Collaborative Architectural Virtual Environments
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	Architecture is built information [1]. Architects have the task of restructuring and translating information into buildable designs.The beginning of the design process, where the briefing is transformed into an idea, is a crucial phase in the design process. It is where the architect makes decisions that influence the rest of the design development process [2]. It is at this stage where most information is unstructured but has to be integrated into a broad context.This is where TAP is positioned - to support the architect in finding solutions through the creation of spatially structured information sets without impairing creative development.We want to enrich the inspiration of an architect with a new kind of information design. A further aspect is workflow in a distributed process where the architect's work becomes one aspect of a decentralised working pattern. The software supports collaborative work with models, sketches and text messages within a uniform environment.The representations of the various media are connected and combined with each other and the user is free to combine them according to his or her needs.

summary	The problem of heuristic biases (illusions) discussed by Tversky and Kahneman (1982) that can lead to errors in judgement by human designers, when they use precedent knowledge presented graphically (Bay 2001). A Cognitive framework of belief, goal, and decision, and a framework of representation of architectural knowledge by Tzonis are used to map out the problem of heuristic biases in the human mind. These are used to discuss what aspects of knowledge can be presented explicitly and digitally to users to make rebuttal more available for human thinking at the cognitive level. The discussion is applicable to both inductive and analytic digital knowledge systems that use precedent knowledge. This discussion is targeted directly at means of addressing bias in the human mind using digital means. The problem of human bias in machine learning and generalisation are discussed in a different paper, and the problems of international or non-intentional machine bias are not part of discussion in this paper.

title	APPROPRIATE LEVELS OF ACCESS: AN EMPIRICAL STUDY ON THE AVAILABILITY OF COMPUTERS IN STUDIO
doi	https://doi.org/10.52842/conf.acadia.2003.119
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 119-127
summary	One of the most significant technological challenges facing architecture schools today is how to provide an appropriate level of access to computing resources. As the computer has become a significant tool in the study and practice of architecture, students need to have access to that tool in order to further their studies. But in facing this question of access, what is “appropriate”? Is there such a thing as too much access? Is 1:1 access—a computer for every student—the minimum level of access that schools and students should accept? Or is there a point beyond which more resources just means more waste; computers sitting idle and unused, or students using the computer for unproductive ends? These questions were the subject of an experimental series of studios in the spring of 2002, wherein three studios were given varying numbers of computers for a term. The use of these computers was then tracked, and compared with previous terms. In tandem, the quality of work produced by these three studios was compared. While additional experiments are most likely needed to draw firm conclusions, the results of this experiment seem to support defining “an appropriate level of access” at less than 1:1.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	A significant quantum of all buildings constructed in modern times is designed for residential purpose. A tremendous amount of money is being spent every year for construction of residential buildings. Therefore, optimization of design becomes very important. In a country like India most people in urban area live in houses having constrained area. A significant part of residential units comes under mass housing either as high-rise building blocks or as plotted developments. In any of such schemes there are large number of housing units for a group of families of whom general characteristics are known but characteristics of individual families are not known at the time of designing. This situation is, however, suitable for scientific investigation and analysis based on statistical surveys. Broadly speaking, this paper suggests approach to deal with this situation of finding optimum layout of rooms of a housing unit for any target group of families when the covered area is so constrained that freedom of using different criteria like aesthetics, structural systems, materials and methods of construction in varieties of ways is drastically reduced. In such constrained area for housing units rooms are generally found rectangular within overall rectangular outline of each unit. Method shown here is valid under this restriction. It is also assumed that number of rooms will be restricted to such number that exhaustive search for design is practically possible within a reasonable time with present day capabilities of normally available PCs.

title	The IKEA Factor - Driving elements of the development of shopping centresat the edges of European metropolitan regions
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	A house and a garden in the suburb, a car for each adult and a TV set with minidish. On weekdays mum and dad work, the children go to school or kindergarten. On Saturdays (or Sundays) the family goes shopping to the shopping centre, where they buy what they need, have a cheap meal and can see a film or just pass the time. That seems to be the way of life for a typical middle class family in the so-called western world, or at least what sitcoms, comics, adverts and films make people believe what it normally should be. That propagated way of living strongly influences people’s and especially consumers’ behavioural patterns and consequently spatialdevelopments, which are the present challenges for urban and regional planners.

title	On the Limitations of Shape Grammars: Comments on Aaron Fleisher’s Article “Grammatical Architecture?”
doi	https://doi.org/10.52842/conf.acadia.2003.279
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 279-287
summary	Shape grammars were introduced by Gips and Stiny in 1972. Since then, there have been many articles and books written by them and their associates. In 1992, Aaron Fleisher, a professor at the School of Planning, MIT, wrote a critique of their work in an article titled “Grammatical Architecture?” published in the journal Environment and Planning B. According to him, Gips, Stiny and later Mitchell, propose a hypothesis that states that shape grammars are presumed to represent knowledge of architectural form, that grammars are “formable,” and that there is a visual correspondence to verbal grammar. The strong version of “the hypothesis requires that an architectural form be equivalent to a grammar.” Fleisher considers these hypotheses unsustainable, and argues his case by analyzing the differences between language, and architecture, and by dealing with the concepts of lexicons, syntax and semantics. He concludes by stating that architectural design is negotiated in two modalities: the verbal and the visual, and that equivalences are not at issue; they do not exist. If there is such thing as a language for design, it would provide the means to maintain a discussion of the consequences in one mode, of the state and conditions of the other. Fleisher’s observations serve as the basis of this paper, a tribute to him, and also an opportunity to present an outline to an alternate approach or hypothesis to shape grammars, which is “nonlinguistic” but “generative,” in the sense that it uses production rules. A basic aspect of this hypothesis is that the only similarity between syntactic rules in language and some rules in architecture is that they are recursive.

summary	During design architects do not only sketch, they combine different kinds of information and representations. The combination of text, image, sketch and/or draft can provoke new associations that keep the design process going. The sketchbook presented here enables architects to use all representations simultaneously, so as to fully exploit their cross-fertilisation. More importantly, it steadily makes suggestions for continuing development of design ideas. These suggestions can take the form of words that are semantically related to the users’ ideas, or of images showing how other architects have developed related ideas into built artefacts. To this end, the sketchbook captures all information the architect/user puts ‘on paper’ and forwards it to a design idea recorder/interpreter called Idea Space System (ISS). In trying to understand the user’s ideas, ISS places all elements captured into a gigantic network, as if part of the frame of reference is made explicit. In the network nodes are words, sketches or images, while links represent relations of various origins. The semantic relations that ISS identifies are shown to the user. At the same time, words are processed as search criteria in DYNAMO, a growing architectural case base, to detect and display design projects that exemplify related ideas. Through the explicit links between early ideas and concrete design cases, the sketchbook acts as a permanent source of inspiration, while stimulating both architects’ creativity and their awareness of the downstream implications of design ideas.

summary	For many years, CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful symbols. These entities only represented the geometrical aspect of the design, but never had knowledge of what they are, or how to behave. With the new CAD systems, this concept has changed into the smart CAD objects. The smart objects will automatically provide all the data related to it: geometry, materials, specifications, price, as well as manufacturers and theoretically any related data. Creating new objects is not an easy straightforward job, and requires more programming skills than previously needed. Taking into consideration the relative difficulties in learning to modify and create new CAD objects, this might lead to a new branch of learning, as the architecture students might not only need to learn how to use the CAD packages but also how to program it in a way that makes them capable of doing what they want rather than doing what the package allow them to do.

title	VISTA VERSA – Critical Considerations on the Evolvement of Designerly Attitudes, Instruments and Networks in Design Driven Studies

summary	Keynote Paper - We are all involved in design.Besides being the (sub)conscious recipients of all sorts of design driven activities, we are professionally concerned with products of design and acts of designing, either as practitioners or as academics, in some cases as both… As someone who was trained as a designer, drifted into design teaching and presently attempts to combine composition research with design practice, I feel there is a need to bridge the cultural gap between design and design research. I intend to put forward the case for more designerly approaches in the study of design. In this context I would like to discuss perspectives for design driven studies by considering the following ensemble of aspects:- the matter of shifting attitudes to design in a scientific context; - the necessity of expanding the scope of instruments of design in relation to methods and insights. - the furthering of opportunities for networks aimed at bringing out and communicating findings concerning different aspects of design.It is on the topic of interaction, between the targeted creativity of designing on the one hand and the open minded search for relevant knowledge, insights and applications on the other, that I would like to dwell. Furthermore, I hope to provoke some thoughts – and hopefully responses – concerning the roles of computer based applications in such studies. What kinds of impulses have computer technologies offered, should they perhaps have offered and indeed might they still be able to offer in this field? I would like to by take a critical look back and try to turn things around, towards a possible view forward…

title	Collaborative Design Process Simulation Game
doi	https://doi.org/10.52842/conf.acadia.2003.133
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 133-141
summary	Collaboration is an important aspect of the architect’s education. However, it is not amenable to the traditional project-based learning pedagogy that works so well for developing form-making skills. Being a process, rather than a product, it cannot be revealed by judging the results alone, which is often how form-making skills are taught and judged. Rather, the process of collaboration is only evident when the number of the participants exceeds a certain threshold, and when actions taken by other participants affect an individual’s on-going design decisions. The advent of on-line, multi-player simulation games provides an analogy and an opportunity to explore interactive collaborative design pedagogies. Their abstract nature helps focus attention on the core issues of the simulated phenomenon, while the playful nature of a game, as opposed to “work,” encourages immersion and role playing that contribute to the learning process. This paper describes an on-line game for simulating the design collaboration process. It espouses to simulate, exercise, and provide a feel for the social dimension of collaboration, by embedding mutual dependencies that encourage players to engage each other—in adversarial or collaborative manners—to accomplish their goals. Specifically, it is intended to help students understand what collaboration is, why it is necessary, and how it is done. The game is modeled after popular board games like Scrabble and Monopoly: players build “houses” made of colored cubes on a site shared with other players. Actions taken by one player immediately affect his/her neighbors. A carefully constructed set of rules awards or deducts points for every action taken by a player and by his/her neighbors. The rules were constructed in such a manner that players who collaborate (in a variety of ways) stand to gain more points than those who do not. The player with the most points “wins.”
