summary	The historical split between visualization and actualization in architectural design has encouraged a disciplinary split between representation (the domain of the designer) and construction (a domain entirely removed from the Architect’s purview). This split between seeing and doing in architectural design can be questioned in the context of contemporary robotic technologies where physical and digital workflows comingle in high-skill, collaborative domains.

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.

summary	The recent convergence of computational design and digital fabrication has made new forms of architectural materialization possible. A workshop conducted at the Royal Melbourne Institute of Technology investigated how differentiated lightweight metal structures may be designed and fabricated under these new conditions. The workshop aim was to complete three such structures; each one is aggregated from aluminum profiles that are robotically assembled according to computationally driven geometric logics. The key challenge was to enable participants, assumed to lack programming and robotic fabrication experience, to design and construct their structures within imposed time constraints. This paper describes the subsequent development of accessible computational design tools and a robust robotic fabrication method for the workshop, and highlights the key decisions taken with their implementation. The workshop results are discussed and the design tools evaluated with respect to them. The paper concludes by recommending an approach to developing computational design tools which emphasizes the importance of usability and integration with the fabrication process.

title	An Inquiry into Designing in Context using Generative Systems
source	International Journal of Architectural Computing vol. 12 - no. 4, 477-494
summary	The use of generative systems has been widely investigated in the architectural design process through different procedures and levels of autonomy to generate form.The digression from abstract pre- existing notions of vocabulary and rules – even when resulting in emergent forms – to address complex real- world contexts is yet a challenging undertaking.This paper explores incorporating context in the process of designing using generative systems from ideation to fabrication, and explores the relationship between the emergent nature of generative design and the situated act of designing while using generative design tools.A course offered for 3rd year architecture students at the Department of Architecture, Ain Shams University, Egypt, was designed for this purpose. 110 students employed systems including shape grammars, L- systems, fractals and cellular automata, to design and fabricate 8 group projects.A discussion around emergence and situatedness is presented, with special attention to the designing process from ideation to fabrication.

summary	This paper discusses ways emerging interactive technologies are adopted by designers and extended into areas of design, education, entertainment, and commerce. It looks, in detail, at various project development stages and methodologies used to engage design focused students into, often complex, technological issues. The discussion is contextualized through a number of case studies of mobile and marker-based augmented reality (AR) applications developed by students. These applications include an app for a fashion based social event that allows participants to preview recent collection additions, an info-navigational app for the High Line elevated urban park in New York City, a marker-based maze game, and an interior decorating interface to visualize various furnishing scenarios. While a number of case studies will be discussed from a developer perspective, the primary focus is on the concept and content development, interface design, and user participation.

summary	Architecture took an evolutionary context over time, where designers were interested in finding pragmatic spontaneous appropriate solutions and met the needs of people in urban and architectural spaces. Whereas, in modern architecture an intense and varied competition happens between architects through various currents of thoughts , schools and movements, however, that creativity was the ultimate goal , and a the same time we find that every architect distinguishes himself individually or collectively through tools of architectural expression and design representation adopting a school of thought, using , for example, the leaves of various sizes and diverse technical drawing tools to accurately show that he can be read by professionals or craftsmen outside the geographical scope to which it belongs .With the rapid technological development which accompanied the digital craft in the contemporary world , The digital craft summed up time, distance and tools , so they gave the concept more appropriate accuracy , as virtualization has become the most effective tool for Architecture To reach the ideal and typical results at the practical level, or pure research. At the level of residential design and on the grounds that housing plays an important role in the government policies and given that housing is a basic unit common to all urban communities on earth , the use of different programs to show its typicality in two dimensions or in the third dimension - for example, using software "AutoCAD " " 3D Max " , " ArchiCAD " ... etc. - gave virtualisation smart, creative and beautiful forms which lead to better understand the used /or to be used residential spaces, and thus the conclusion that the life system of dwelling under design or under study , as can specifically recognize spatial structure in housing design - using digital software applying "Space Syntax" for example - in the shadow of slowly growing digital and creative development with the help of high-speed computers . the morphological structure of the dwelling is considered to be the most important contemporary residential designs Investigation through which the researcher in this area aims to understand the various behavioral relations and social structures within the projected residential area, using Space Syntax techniques. Through the structural morphology of dwellings can be inferred quality networks, levels of connectivity and depth and places of openness or closure within the dwelling under study, or under design. How, then, have intelligently contributed this digital craft to the perception of those spatial fixtures ? The aim of this research is to apply an appropriate program in the field of vernacular residential design and notably Space syntax which relate to the understanding and analysis of spatial structures, and also demonstrate its role at the morphological and spatial structure aspects, and prove how effective it helps to understand the social logic of domestic space through social individual/collective relationships and behaviors projected on the spatial configurations of dwellings. The answer to the issue raised above and at the methodological aspect, the study discussed the application of space syntax techniques on the subject. The findings tend to prove the efficiency by comparing samples of Berber vernacular domestic spaces from the Mzab, the Aures and Kabilya in Algeria, and has also led to ascertain the intelligibility of space syntax techniques in reading the differences between the behaviors in domestic spaces in different areas of the sample through long periods of time .

title	A Context Based Approach to Digital Architectural Modelling Education
doi	https://doi.org/10.52842/conf.caadria.2014.811
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 811–820
summary	This paper presents a context based framework for introducing digital modelling and fabrication to architecture students. Modelling has being taught either as a separate skill, or introduced within a comprehensive context of conventional design approaches. We argue that, a ‘digestive context’ might guide students to gain designing experience with/in digital media in a gradual and a cumulative way. This paper is based on a series of modelling and fabrication exercises as part of a one-semester digital design and modelling studio course for postgraduate students. We focus on the impact the initial exercises we assigned our students had on the final design product; We discuss the affordance and adaptability of the method that was developed by the students.

summary	project 3xLP, the winning submission to the TEX-FAB SKIN competition, is a continuation of design research on the structural properties of textured stainless steel sheeting, which typically is used for skinning and other non-structural purposes. The team conducted performative analyses of the material, and verified the results through full-scale prototyping. Structural studies relied on scale shifts that began with molecular composition and culminated with large-sale geometric systems. The work provides evidence of the adaptability, rigidity, and high performance of thin-gauge, textured metals; it establishes the groundwork for new structurally-based design possibilities using sheet steel.

summary	While the digital era has brought with it a vast assortment of tools from which we can generate form and geometry, often the result is a tendency to focus primarily on either surfaces or solids as a means of modeling for representation or fabrication which consequently impact the various fabrication and construction techniques deployed in order to realize such digital models. This paper presents an approach to coalesce techniques of surface generation via computational tools, and strategies for constructing volumetric elements through a process of backfilling with composite materials.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

Drawing boards have been exchanged with relatively small 30” inch monitors, pens and rulers have been exchanged with advanced digital tools mostly though disturbing, making the creative process of design merely a frustrating one. So what have we gained from CAD. Certainly a lot, but mostly the possibility to combine and fuse projects. Simulating future use and behaviour, revealing design issues and failures before actually built. Still data fusion is a relatively new challenge albeit quite obvious trying to assemble models coming from different systems and vendors representing different professional domains. This paper discusses data exchange and data fusion in general and presents a new development, which gives the possibility to enhance data as intelligent objects opening a whole new paradigm for both data exchange and data fusion.

title	"Tangle Jungle": An Experimental Project to Combine Collaboration and Craftsmanship in Digital Design Pedagogy
doi	https://doi.org/10.52842/conf.caadria.2014.013
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 13–22
summary	Tangle Jungle was an experiment in an alternative method of design and making for the digital age. The aim of the project was to interpret and reenact traditional craftmanship through today's digital tools. For a particular study on the subject, we looked at the theory and works of William Morris. Morris had an exceptional taste for medieval art and produced, among other things, hand-woven carpets that are still studied today. Morris reinvented the art of his time by reviving pre-industrial modes of production and designs. Today, the digital age is experiencing a similar paradigm shift. Digital tools already work, in many instances, as a direct extension of the hands of a new breed of digital artisan makers. It is possible to assess that the digital is getting closer to Morris's notion of craftsmanship. Tangle Jungle became a testing ground for this historical connection, bringing forth the question, can we redefine our own digital craftsmanship as a form of digitally reenacted Gothic revival?

summary	"The introduction of digital tools in the production of architecture undoubtedly constitutes the main force behind contemporary architectural innovation. In addition, the interaction of digital technologies with analog craft manufacturing -a rather unexplored field of study- suggests a wide range of novel opportunities. This research focuses on developing a framework for deploying digital design techniques to the production of bricks under vernacular technology as a medium of achieving geometrical variations and functional complexity in domestic-scale projects. Solid clay bricks are embedded in traditional ceramic-construction culture. Thus, this investigation faces the challenges of making a feasible innovative system in a country where digital fabrication is not an economically viable option, and engaging a design that can be easily implemented with current hand-labour. Consequently, the new bricks would be massively introduced in the construction market, allowing novel formal and functional possibilities for designers.

title	Three Little Shacks
doi	https://doi.org/10.52842/conf.caadria.2014.883
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 883–892
summary	The paper is premised upon the notion that tools and techniques have the potential to resist the premature prefiguring of problems and solutions in projectbased activity, with particular relevance in collaborative design practices. The architect’s métier and mode of knowledge production is marked by the capacity to make artefacts. Because our age is characterized by the imperative to innovate and evolve technically, architectural ideation must now engage an array of computationally-based tools for imaging, information management, simulation and fabrication. This paper, framed within the theoretical and productive context of a research-creation project, investigates the ontological status of process-work, speed, and the notion of failing fast through the prototyping of three small buildings, or shacks. It does this through a strategic choreography of factual and counterfactual investigations that give rise to fabricative knowledge incapable of being prescribed conceptually from the outset. It will be claimed that, in the case of architecture, the potential of technics to reflectively and playfully re-work things and ideas is also a participatory mode of ethical engagement.

title	Generative-Glass: Prototyping Generative Architectural Systems with Artisan’s Glass-Blowing and Automated Digital Fabrication Techniques
doi	https://doi.org/10.52842/conf.caadria.2014.389
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 389–398
summary	This paper aims to investigate the ways in which the traditional processes of glassblowing techniques could be incorporated with contemporary generative design processes in the realization of new novel architectural systems. Pedagogical issues on how such prototyping processes could be better integrated within architectural education are also discussed. With the use of algorithmic design methodology to generate/visualize the components assembled in multitudes and digital fabrication machineries to produce the necessary moulds/jigs/tools/connection joints, a series of 5 different glass prototypes have been actualized at the scale of 1:1 or otherwise. The work is the direct outcome of a new programme founded and directed by the author as part of the Architectural Association (AA) School of Architecture‘s Visiting School in 2013. Part 1 briefly introduces the specific agenda and how the corresponding structure of the programme is designed to facilitate the glass research work done concurrently at the digital fabrication laboratory and glassblowing studio. Part 2 would systematically discuss in detail the design of each of the 5 main glass prototypes made, presented alongside photographs and diagrams to illustrate the prototypes’ respective assembly and fabrication logics. Part 3 would evaluate the work done and project plans for the next iteration of the research in 2014.

title	Approaching Sentient Building Performance Simulation Systems
doi	https://doi.org/10.52842/conf.ecaade.2014.2.049
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 49-60
summary	Building designers make decisions in early design stages that have large impact on building performance, including those of energy-, daylight- and indoor environment performance. Building performance simulation (BPS) tools can support the designer, in making better decisions, by providing the performance consequences of design choices. However BPS tools often require deep technical knowledge and is too time consuming to use to effectively support the design exploration in the early design stages. To solve this challenge, the current paper proposes: Sentient building performance simulation systems, which combine one or more high precision BPS tools to provide near instantaneous performance feedback directly in the design tool. Sentient BPS systems are essentially combining: 1) design tools, 2) parametric tools, 3) BPS tools, 4) dynamic databases 5) interpolation techniques and 6) prediction techniques as a fast and valid simulation system for the early design stage.
