title Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

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.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London.

summary This paper makes a case for exploring the feasibility of utilizing the advanced graphics and sound systems of contemporary gaming engines to promote architecturally relevant work. Gaming engines, while developed largely for the PC entertainment industry, have vast potential for application in architecture. This paper will explore the depth of this potential and will outline work demonstrating the advantages and the limitations of this technology. The supporting research and observations examine the technology and reveal its potential usefulness as an instructional or depictive authoring tool. Game engines were selected that had appropriate graphical prowess, but were customizable as to allow the removal of game-specific features (to create a “professional” user interface). Projects were authored that expressed complex building details using the engine for visual depiction. The details, which included constructional components, structural assemblies, or simple design nuances, were modeled with 3D geometry and realistically textured and lighted. The game engine allowed one user or many remote simultaneous users in the virtual environment to interactively explore the presentation in real time. Scripts were developed to encourage end-users to interactively disassemble or reassemble building components as desired. Audile and/or text-based information regarding the assembly sequence were provided by exploiting the game interface features. Furthermore, interactive object scaling was provided to facilitate analysis of component relationships.

title Realism vs. Reality in Digital Reconstruction of Cities
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The digital reconstruction of existing cities using virtual reality techniques is being increasingly used. For consultants, municipalities and planning departments these models provide decision support through visual simulations (El Araby, 2001). For academia they provide a new tool for teaching students urban design and planning (Okeil, 2001). For authorities they provide a tool for promoting the city on the world wide web trying to attract more businesses and tourists to it. The built environment is very rich in detail. It does not only consist of open spaces surrounded by abstract buildings but it also includes many smaller objects such as street furniture, traffic signs, street lights, different types of vegetation and shop signs for example. All surfaces in the built environment have unique properties describing color, texture and opacity. The built environmentis dynamic and our perception is affected by factors such as pedestrian movement, traffic, environmental factors such as wind, noise and shadows. The built environment is also shaped by the accumulation of changes caused by many influences through time. All these factors make the reconstruction of the built environment a very complex task. This paper tries to answer the question: how realistic the reconstructed models of urban areas can be. It sees “Realism“ as a variable floating between three types of realties. The reality of the physical environment which we are trying to represent. The reality of the digital environment which will host the digitally reconstructed city. And the reality of the working environment which deals with the problem of limitation of resources needed to digitally reconstruct the city. A case study of building a 3D computer model of an urban area in the United Arab Emirates demonstrates that new time-saving techniques for data acquisition can enhance realism by meetingbudget limitations and time limitations.

title PROCESS INTEGRATION IN BUILDING DESIGN USING THE PARAMETER-BASED DESIGN STRUCTURE MATRIX
source Design Studies, 27(1), pp. 99-122In B. Tuncer (Ed.), E-Activities in Building Design and Construction. (pp. 63-72). Paris: Europia
summary This paper reviews existing process models in the Architecture-Engineering-Construction (AEC) industry and identifies two common deficiencies in them: 1. Current process models used in the industry still have a top-down approach including very little information about interrelationships at lower levels. Although these models provide a good overview of the design process, they are often too abstract to define, in detail, for complex multi-parameter problems. 2. Iteration is an important problem in collaborative design. However, most of the existing process models fail in identifying and minimizing it. With a view to alleviate these problems, this paper introduces the parameter-based Design Structure Matrix (DSM) as a tool for process integration and improvement in building design. The uses of the tool are shown via simple examples and suggestions are made for further research.

summary This paper presents a constraint-based modeling system, integrated into a widely used CAD modeler. Using a notification mechanism, the system records the precision functions called by the user in order to maintain geometric relations between points locations and source objects. These relations are stored in a directed graph which allows an automatic update of the model.

source Proceeding of the 3rd China Urban Housing Conference, July 3-5 2003, Center for Housing Innovations, Chinese University of Hong Kong, ISBN 962-8272-26-8, pp. 417-424
summary This paper describes a research on building Integrated Information System for Urban Spatial Development. The objective of the research phase discussed in this paper is to define a prototype of information system that basically facilitates information communication among involved participants in an urban spatial development planning. The system is designed by putting stress on local community. Their spatial perception and the availability of GIS technology in local context become constraints in building the system. Internet becomes the main alternative for information dissemination for this phase. This is also supported by the use of web-based GIS as framework of information system. Through few socialization sessions, the proposed model has indicated a prospected alternative to be seamless communication media among participants. To support an easy-access for local people in using this information system a mechanism of information access has been proposed in the form of local information center.

title The Geographical Alpine Information System “Galpis” in the Raumalp Project. Outlay and Output
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary RAUMALP, an interdisciplinary research project of the Austrian Academy of Sciences, shall examine problem areas of spatial development on community level in the Austrian alpine region. The aim is the investigation of scientific basics for political decision finding, especially for the regional-specific realisation of the Alpine Convention. All ascertained information shall be included in “GALPIS”, a comprehensive Alpine Space Information System. GALPIS based on ESRI ArcGIS and MS Access software works with data from different sources, like ISIS, the electronic data base of Statistic Austria, and original data and maps gathered and elaborated by the working groups of RAUMALP. This also includes ecological raster data. Dealing with administrative units, „real“ space and raster space, RAUMALP will integrate the different space levels mostly to administrative spatial units representing the existing 1145 communities of the RAUMALP study area. This will be realised by overlay of grids, types of land use and communitypolygons. Major task of GALPIS is a conversion of former communal data (p. e. 1451 communities in 1951) that should represent the recent administrative boundaries. By this way it is possible to make thematic and time-integrative analyses of community data. GIS modelling of the six case studies is more complex. The conceptual model has to integrate several vector and raster layers such as land plots (“Digitale Katastralmappe”), types of land use (“Land Use and Land Cover Austria” by M. Seger) and biodiversity. P. e., the working group settlement is using a logical data model based on the entity “building” with the attributes “construction”,“function”, etc.

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.

summary This study describes statue in the early phase of design, the approach taken by its conceptual development and manipulation. And on the developing digital tools provide a computational support for the process of indexing and retrieving. The digital modeling also addresses specifically architectural programming, adjacent relationship between the building element and articulation in designing. The overall in building mass development starting with reasoning of the conceptual model in early phase try to find evocative cases to help designer thinking. And finally discuss some issues and challenges of artificial intelligent. The research for representing designer’s creativity and searching solution provide another way to generate an articulating conceptual model. The integration approach of research starts with the pure case-based and rule-based reasoning system to help designer generate more understandable and creative product in the architectural design application.

title Developing a Building Design Compiler that Frequently evaluates Building Design Performance within the Design Process

summary This paper demonstrates an experience in the development of a design performance evaluation system that can frequently evaluate building design performance within the design process in a real-time manner. The evaluation system, that we call "design compiler," is composed of several modules such as a front-end component-based CAD engine, a knowledge base, and a set of design agents. The notion of the design compiler is quite similar to a compiler for computer programming such as a C compiler. While a computer programmer compiles a set of programming codes to check compiling errors during the implementation of a software system, an architectural designer can 'compile' his/her intermediate design product to evaluate design errors during the design process. The compilation can be done immediately at any level or any time during the design process in a real-time manner. We expect that this compiling process will dramatically increase design feedbacks, and thus result in a better design product. Further research issues that have been identified at the end of the research include increasing the modeling capability, extending to multi-story building representation, developing various design agents, exploring better ways to request and manage design knowledge, and supporting design collaboration.

summary A decade ago, Bill Mitchell wrote “Chroniclers of our era may one day write ‘What was computer-aided design?’ To them, it will just be design.” Because of the proliferation of digital tools for design, we are rapidly forgetting that there was ever design before computing. Ask an undergraduate student to describe the design process. There is a good chance that the student will mention using CAD and 3D modeling. Ask a contractor how to practice the profession of building.

source Proceedings of the Generative Arts conference, Milan, 2003
summary We would like to present some recent work using cellular automata and agent modelling for the generative design of building configurations. The cellular automata is based on a 3d terrain model of a site (taken from the recent Europan competition) which is encoded with both topological and economic data, and agents that are light sensitive and which reconfigure the developing architecture by checking overshadowing and spatial occupation. The emergent pattern of development therefore results from an understanding of the programmatic and the spatial parameters of the task, and is intimately related to the site and its peculiarities.

summary As a result of growing activity in the field of renovation and building within existing built contexts, modern digital tools and methods are increasingly in demand. Support of the planning process means: the step-by-step capture of building-relevant information, a rule and parameter-based development of solutions and the combination of traditional and automated methods and technologies used for model creation (building surveying) and model transformation (planning). This article discusses general requirements and the results from our own research and development as well as illustrating how building surveying can already contribute to the planning process more effectively using currently available tools.

title Internet based support for architectural planning processes
source International Journal of Architectural Computing vol. 1 - no. 3
summary As building projects become increasingly more complex, the number of project participants grows as does their spatial distribution. An effective decentralised work process and co-operation is of increasing importance. The global computer network, the internet, has great potential and recent times have seen the development of a variety of techniques in this field. The project described here is based upon this approach and also takes it a step further. A specific analysis of the topic and the subsequent identification of potential approaches formed the basis for an architectural application that brings the architect in contact with other project participants using the internet as a powerful yet simple and easy to use medium.

title Digiosk Digital Design to Robotic Deployment in Two Months
doi https://doi.org/10.52842/conf.caadria.2003.811
source CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 811-826
summary In this paper, we discuss Kit-of-parts Theory and how it applies to the design, manufacture, and operation of a small robotic deployable demonstration structure called the Digiosk (Howe, 2001). "Kit-of-parts Theory" refers to the study and application of objectoriented building techniques, where building components are predesigned / pre-engineered / pre-fabricated for inclusion in joint-based (linear element), panel-based (planar element), module-based (solid element), and deployable (time element) construction systems. The Digiosk is an exposition display kiosk that was designed and manufactured digitally, and brought from concept to robotic functionality in a short period of time. Using kinematic mechanisms the cylinder opens up and deploys into a 2.7m cubical display booth complete with integral power and network connections. The kiosk was designed using a solid modeler, from which data was extracted to drive digital manufacturing processes. Owing to the well-developed understanding of Kit-of-parts Theory and the new "kinematic architecture" principles, the paperless process yielded a working prototype only eight weeks after initial conceptualization. The paper concludes with a discussion of how these concepts can be applied to large-scale projects and design processes.

title The Level of Knowledge of CAD Objects within the Building Information Model
doi https://doi.org/10.52842/conf.acadia.2003.173
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. 173-177
summary The first generation of CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful graphics symbols. These entities only represented the geometrical properties of the architectural elements. With the present emerging generation of CAD systems, a new concept shifts a drawing-based model into a Building Information Model with the potential of modeling true architectural objects. Theoretically, these CAD objects will provide all related data to the designer describing the geometry, as well as any related data associated with how the object is actually used. The knowledge required to support an object should have structure to it. Different levels of knowledge need to be included, such as the geometrical information, which should be flexible enough to accommodate any type of shape and modification while keeping the object’s integrity as a unit and maintaining its relations to other objects. The CAD object concept, as remarkable as it is, might also have potential problems. It has some implications over the design process, as well as the architectural profession itself.

title XML-Based Interactive 3D Campus Map
doi https://doi.org/10.52842/conf.caadria.2003.631
source CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 631-640
summary This paper presents the development of a prototype XMLbased 3D campus map using the 3D VML library. Many universities in the U.S. use two-dimensional (2D) raster image to provide the campus map along with additional building information on their Web site. Research shows that three-dimensional (3D) expression of the 3D objects helps human beings understand the spatial relationship between the objects. Some universities use 3D campus maps to help visitors more intuitively access the building information. However, these 3D campus maps are usually created using raster images. The users cannot change the view point in the 3D campus map for better understanding of the arrangement of the campus. If the users can navigate around in the 3D campus map, they may be able to locate the building of their interest more intuitively. This paper introduces emerging Web technologies that deliver 3D vector graphics on the Web browser over the internet, and the algorithm of the prototype XML-based 3D campus map. Some advantages of using VML in delivering the interactive 3D campus map are also discussed.
