title	Building Thailand's tallest Ganesh: CAD/CAM integration in conventional metal fabrication
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 337–346

summary	Ganesh (Ganesa or Ganesha) is a Hindi god well known for his distinguishable elephant head and widely revered as the god of success or remover of obstacles. Patrons in Thailand have worshipped Ganesh and respected him by means of erecting statues of Ganesh in various poses and sizes throughout the country. In late 2008, the people of Chacheongsao, a province located East of Bangkok, decided to create Thailand’s tallest standing Ganesh statue made with bronze reaching heights up to 39 meters and situated on the Bangpakong river bank overseeing the city and its people. The author and design team was approached by representatives from Chacheongsao and commissioned to advise the process from conception to construction. The challenge started with seeking appropriate computer-aided design and manufacturing technologies and innovative processes to guide the design team throughout the production. The 0.60-meter bronze cast sculpture of the Ganesh was scanned using a 3D optical scanner to generate a solid model of the statue. A surface model was then extracted from the 3D model to firstly determine the most efficient structural support within the statue and secondly to generate surface strips for the foundry to create actual bronze casts. The construction of the project began early 2009 and the statue has since been erected from its base to currently its head. During construction, the author and design team has encountered several problems translating pixels to parts. Several errors have occurred during the mould and cast production process as well as construction errors on site causing mismatches of the structure and surface, misalignments, and protruding structural supports and joints. The lessons learned from this project is documented and analysed with hopes to create a more effective process for future projects with similar requirements.

title	A survey of computer software for the urban designprocess
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	Urban design is concerned with the shape, the surface and the physical arrangement of all kinds of urban elements, the basic components that make up the built environment, at the level of buildings, spaces and human activities. It is also concerned with the non-visual aspects of the environment, such as noise, wind and temperature and humidity. The city square is a particular urban element which can take many forms and its geometrical relationships such as maximum dimensions, ratio of width to length and building height to length have been analysed for centuries (Alberti 1475), (Vitruvius 1550), (Sitte 1889), (Corbett 2004). Within the current urban design process there are increasing examples of three dimensional computer representations which allow the user to experience a visual sense of the geometry of city squares in an urban landscape. Computer-aided design and Virtual Reality technologies have recently contributed to this visual assessment, but there have been limited attempts at 3D computer representations which allow the user to experience a greater sense of the urban space. This paper will describe a survey of computer tools which could support a more holistic approach to urban design and which could be used to simulate a number of urban texture and urban quality aspects. It will provide a systematic overview of currently available software that could support the simulation of building density, height, colour and style as well as conditions relating to noise, shading, heat, natural and artificial light. It will describe a methodology for the selection and filtering of appropriate computer applications and offer an initial evaluation of these tools for the analysis and representation of the three-dimensional geometry, urban texture and urban quality of city centre spaces. The paper is structured to include an introduction to the design criteria relating to city centre spaces which underpins this research. Next the systematic review of computer software will be described, and selected tools will undergo initial evaluation. Finally conclusions will be drawn and areas for future research identified.

title	Tangible Augmented Reality for Design Learning: An Implementation Framework
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 350-356

summary	Nowadays, it is becoming more and more popular for teaching and learning to be supported in technology-supported settings. These digital technologies create new instructional methods. Tangible Augmented Reality (AR) technology can construct an innovative and interactive learning space by merging computer-generated learning materials and stimuli of virtuality into a real space. Different cognitive and social-learning processes might be involved with different learning activities that can be potentially supported by different technology modes of tangible AR. This paper discusses an empirical research framework for designing and implementing tangible AR technologies to improve the pedagogical effectiveness of learning processes involved in architectural design education. The research framework includes the theoretical process of applying tangible AR in design learning, the devised experimentations and associated methodology. Issues and benefits of incorporating tangible AR into architectural design learning are also investigated and discussed.

title	Constructing Information: Towards a Feedback Ecology in Digital Design and Fabrication
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 182-191

summary	As strategies evolve using digital means to navigate design in architecture, critical process-based approaches are essential to the discourse. The often complex integration of design, analysis, and fabrication through digital technologies is wholly reliant upon a process-basis necessitating the use of a design feedback loop, which reinforces critical decision-making and challenges the notions of how we produce, visualize, and analyze information in the service of production and assembly. Central to this process-based approach is the effective and innovative integration of information and the interrogation of material based explorations in the making of architecture. This fabrication ‘ecology’ forces designers to engage complexity and accept the unpredictability of emergent systems. It also exposes the process of working to critique and refine feedback loops in light of complex tools, methods, materials, site, and performance considerations. In total, strategies for engaging this ‘ecology’ are essential to accentuate our present understanding of environmental design and theory in relation to digital processes for design and fabrication. ¶ This paper recounts a design/fabrication seminar entitled “Constructing Information” in which architecture students examined an environmental design problem by way of the design feedback loop, where their efforts in applying digital design and fabrication methods were driven explicitly by material and site realities and where their work was executed, installed, and critically explored in situ. These projections raise important questions about how information, complexity, and context overlay and merge, and underscore the critical potential of visual, spatial, and material effects as part of a fabrication-oriented design process.

title	Digitally Mediated Regional Building Cultures
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 91-98
summary	Designs are complex energy and material systems and products of diverse cultural, economic, and environmental conditions that engage with their extended context. This approach relates architecture to the discourse on complexity. The design research described in this paper introduces an extended definition of ecology that expands the scope of design discourse beyond the environmental performance of materials and types of construction to broader cultural considerations. Parallel to enabling rich formal explorations, digital modeling and fabrication tools provide a basis for engaging with complex ecologies within which design and building exist. Innovative design applications of digital media emphasize interdependencies between new design methods and their particular context in material science, economy, and culture. In British Columbia, influences of fabrication and building technology are evident in the development of a regional cultural identity that is characterized by wood construction. While embracing digital technology as a key to future development and geographic identity, three collaborative digital wood fabrication projects illustrate distinctions between concepts of complexity and responsiveness and their application in design and construction.

source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 593-600
doi	https://doi.org/10.52842/conf.ecaade.2008.593
summary	The present paper deals with the theoretical and technical reflection on basic structural principles that allow the generation and controlling of architectural complexity of double curvature surfaces.Despite the difficulties in designing and building such complex forms, Chile has several examples that were developed and built during the first half of the twentieth century. All of them were developed with local building technologies which studied the implementation of experimental and simple materials with innovative mounting techniques. All of them explored new structural concepts generating great interest of architectural spaces for religious cult, housing and civil works. The research objective of this work deals with the recognition and analysis with contemporary modelling and simulation tools that can reveal the type of relationship that occurs between the initial conception of the architectural shape and membranous structural surfaces. Their curvature and sleekness generated innovative structural spaces that contain an architectural envelope with clear and revealing expression of the acting forces.

title	Applying Scientific Simulation to Integrate Thermoelectric Conductor Module into Architectural Design – Smart Wall for Thermal Comfort
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 200-210
doi	https://doi.org/10.52842/conf.acadia.2005.200
summary	This paper presents the innovative architectural design concept, which is to integrate the new material and technology into the building design to achieve the thermal comfort and at the same time reduce the energy consumption of the building by making use of the renewable energy, including solar and wind energy. The system is developed based on the idea of regional thermal comfort in building. The advantage of the system is the environmental friendly approach, costless operation, reliability, flexibility, scalability and adaptability for the integration to the building design. With the design concept, we tried to do two application designs in two virtual sites. One is a badminton court for the 2008 Beijing Olympic Games and the other is a cooling pond in a shopping mall. We will introduce how computational simulation can contribute to the prediction of the performance of the design. We will also discuss how the computation simulation can help in the design optimization process. Through the development of the new design integration of the material to the building, we would like to feedback to the material industry to encourage further collaboration and development in the material enhancement, so that both industries and the society can benefit from the advancement.

title	Creating Metallic Color Sequences for an Architectural Wall
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 308-315
doi	https://doi.org/10.52842/conf.acadia.2008.308
summary	A metallic paint scheme for an architectural wall is created using computer aided color appearance design techniques. New computer graphic hardware that allows real-time rendering of complex reflectance functions is employed to produce photo-realistic images of the metallic paint applied to the surface of the wall. An interpolation scheme is developed that permits one and two dimensional metallic shade sequences to be determined between individual bricks in a single row of the wall and between the complete rows of bricks that compose the wall. Paint formulation software, originally developed for auto refinish applications, is used to determine the paint mixtures necessary to realize the metallic colors in the design. A prototype of the wall is constructed and exhibited in a museum gallery.

doi	https://doi.org/10.52842/conf.acadia.2008.364
summary	In this research project we explore the defined design and application of digitally fabricated wall panels for room-acoustical architectural interventions. In Particular, we investigate the room-acoustical criteria applying to everyday used spaces. We present a digital design and fabrication process developed to create non-standardised panels and two case studies which apply this process on the acoustical improvement of a specific room situation. Our aim is to find correlations between digitally fabricated surface structures and sound- aesthetical characteristics, in order to utilise these for the architectural design.

summary	The intent of this paper is to jointly investigate fundamental processes in living systems, their potential application in the novel design of responsive surfaces and spatial structures, and their applicability in biomedicine. Through the investigation of organotypic biological models designed to recapitulate breast tissue homeostasis and cancer, parallel models work to unfold the parametric logic of these biological and responsive membrane and scaffold structures, thereby revealing their deep interior logics. The result is an abstract surface architecture capable of responding dynamically to both environment (context) and to deeper interior programmed systems.

title	Structural Analysis as Driver in Surface-Based Design Approaches
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 19-39
summary	This research argues for novel strategies to integrate structural analysis data in architectural design. Instead of a linear procedure of analysis, synthesis, evaluation and post-rationalization a synthesis/evaluation loop is installed which embeds structural analysis data as design driver from early on. The approach regards structural performance as one design criteria within a network of different requirements. An equilibrium of multiple parameters is aspired to instead of a single-parameter-optimum. The research is conducted via a custom-made digital interface between 3d modelling software and an application for structural analysis of space frames. The information exchange provides the basis for successive strategies within a collaborative design process of spatial roof structures: negotiation of an overall form and a multi-dimensional improvement of space frame topologies by a Genetic Algorithm (GA).

title	Gulliver in the land of Generative Design

summary	The current trend in architectural design towards architectural computing has been treated both from a philosophical standing point and as an operational systems’ problem, in a quest for explications which could at last break ground for a more broad development and adoption of design tools. As Kostas Terzidis (2007) puts it, the intuitiveness that architects have put on so high a pedestal seems to be the central issue to be dealt with by both views. There seems to be no apparent shortcut toward the reconciliation between traditional practice and new media and most certainly it is not only a problem of interface design, but one of design method clarification and reinterpretation of those methods into computing systems. Furthermore, there’s no doubt left as to whether computing systems can generate such new patterns as to impact our own understanding of architecture. But even if computer algorithms can make possible the exploration of abstract alternatives to an abstract initial idea, as in Mathematica and Processing, the issue of relating abstract and geometric representations of human centered architecture lays in the hands of architects, programmers or, better yet, architect-programmers. What seems now to be the relevant change is that architectural design might escape from the traditional sequence embedded in the need – program – design iterations – solution timeline, substituted by a web of interactions among differing experimental paths, in which even the identification of needs is to be informed by computing. It is interesting to note that the computational approach to architectural design has been praised for the formal fluidity of bubbles and Bezier shapes it entails and for the overcoming of functionalist and serialization typical of modern architecture. That approach betrays a high degree of canonic fascination with the tools of the trade and very little connection to the day to day chores of building design. On the other hand, shall our new tools and toys open up new ways of thinking and designing our built landscape? What educational issues surface if we are to foster wider use of the existing technologies and simultaneously address the need to overtake mass construction? Is mass customization the answer for the dead end modern architecture has led us to? Can we let go the humanist approach begun in Renascence and culminated in Modernism or shall we review that approach in view of algorithmic architecture? Let us step back in time to 1726 when Swift’s ‘Travels into Several Remote Nations of the World by Lemuel Gulliver’ was first published. In Swift’s fierce critic of what seemed to him the most outrageous ideas, he conceived a strange machine devised to automatically write books and poetry, in much the same generative fashion that now, three centuries later, we begin to cherish. “Every one knew how laborious the usual method is of attaining to arts and sciences; whereas by his contrivance, the most ignorant person at a reasonable charge, and with a little bodily labour, may write books in philosophy, poetry, politicks, law, mathematics and theology, without the least assistance from genius or study. He then led me to the frame, about the sides whereof all his pupils stood in ranks. It was twenty foot square, placed in the middle of the room. The superficies was composed of several bits of wood, about the bigness of a dye, but some larger than others. They were all linked together by slender wires. These bits of wood were covered on every square with paper pasted on them; and, on these papers were written all the words of their language in their several moods, tenses, and declensions, but without any order. The professor then desired me to observe, for he was going to set his engine at work. The pupils at his command took each of them hold of an iron handle, whereof there were forty fixed round the edges of the frame; and giving them a sudden turn, the whole disposition of words was entirely changed. He then commanded six and thirty of the lads to read the several lines softly as they appeared upon the frame; and where they found three or four words together that might make part of a sentence, they dictated to the four remaining boys who were scribes. This work was repeated three or four times, and at every turn the engine was so contrived, that the words shifted into new places, as the square bits of wood moved upside down.” (Jonathan Swift, Gulliver’s Travels, A Voyage to Balnibarbi) What astonishing forecast did Swift show in that narrative that, in spite of the underlying incredulity and irony, still clarifies our surprise when faced to what might seem to some of us just an abandonment of all that architects and designers have cherished: creativeness and inventiveness. Yet, we could argue that such a radical shift in paradigm occurred once when master builders left the construction ground and took seat at drafting boards. The whole body of design and construction knowledge was split into what now seem to us just specialties undertaken by more and more isolated professionals. That shift entailed new forms of representation and prediction which now each and all architects take for granted. Also, Cartesian space representation turned out to be the main instrument for professional practice, even if one can argue that it is not more than the unfolding of stone carving techniques that master builders and guilds were so fond of. Enter computing and all its unfolding, i.e. DNA coding, fractal geometry, generative computing, nonlinear dynamics, pattern generation and cellular automata, as a whole new chapter in science, and compare that to conical perspective, descriptive and analytical geometry and calculus, and an image begins to form, delineating a separation between architect and digital designer. In previous works, we have tried approaching the issues regarding architects education in a more consensual way. But it seems now that the whole curricular corpus might be changed as well. The very foundations upon which we prepare future professionals shall change, not only in College, but in High School as well. In this paper, we delve further into the disconnect between current curricula and digital design practices and suggest new disciplinary grounds for a new architectural education.

title	Automated Cost Analysis of Concept Design BIM Models

summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The objective of the present research was to study the use of animation techniques as a tool for the design process. The study started with a literature review about the different possible applications of animation techniques in architectural design. Four main categories of applications were found: (1) space representation and “walk through”, (2) simulation of articulated elements and kinetic structures, (3) visualization and analysis of functional aspects of the buildings, such as circulation and fire escape, and finally (4) the generation of novel shapes. The second part of the research consisted of a design exercise in which animation techniques were used to generate a shape. For this purpose a wind simulator was used in 3DMAX. Next, Paracloud software was used to automatically generate a rib structure that allowed to produce a scale model of the shape with a laser cutter.

title	Visual-Physical Grammars
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

title	Medial Representations for driving the Architectural Creative Process
source	International Architecture Symposium, Barcelona, April 2008
summary	Medial representations of shape provide a powerful framework for the analysis and genesis of architectural forms,layouts, landscapes, cityscapes. In this paper we explore their potential use in driving the architectural creative process for 2D and 3D applications. We consider both the aspects of (i) the analysis of exisiting architectural layouts, and (ii) the genesis of novel ones. The archetypal medial representation of shape is the “medial axis” of Harry Blum (circa 1960). Boundary elements, the outline samples of the objects of interest, are used as the source of a wavefront propagation, for which the quenching points constitute axial symmetries. In 2D layout applications the resulting medial axis (MA) takes the form of a graph which unites geometry and topology of the objects and the field they occupy in one single framework. In the following we first survey the topic of shape representation via medial structures and consider their specific use in architectural analysis and genesis. We then report of early works in extending such ideas for novel applications relevant to architecture.

title	The Most Important Airplane In The History Of Architecture

summary	Composite structures consist of high strength carbon threads held together in a matrix of epoxy resin or thermoplastics. Surfaces made from these materials are typically 10 times lighter and 1.5 times stronger than aluminum. Both simple and highly contoured shapes possessing extreme strength can be produced using a computer controlled fiber placement machine (FPM). These incredibly thin, corrosion resistant membranes require little or no supplemental support to manage loads and enclose space. The computer’s ability to determine the precise location of each fiber strand in a fiber placed part also facilitates unprecedented control of its aesthetic and functional properties. Fiber placement technology integrates building components that would normally be separated into clearly distinct systems. Here ornament, structure and cladding are collapsed into one material process. This paper explores the architectural potential of a technology normally reserved for aerospace applications through research conducted in close collaboration with fiber placement engineers at Automated Dynamics in Schenectady, New York (ADC).

summary	This paper describes an introductory computational design course for graduate students of design in which Islamic star patterns are utilized in teaching computational logic and design rules. Formal descriptions of eight pointed Islamic star pattern that depict a variety of geometrical structures and constraints of the Euclidean shapes are extracted with the shape grammar method. Then star pattern generator that runs on a specific CAD system is developed by encoding these formal descriptions in systems scripting language. The examples of new designs are generated, and then fabricated using various CAM technologies.

title	Certain assumptions in Digital Design Culture: Design and the Automated Utopia
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 137-148
summary	Much of the research efforts in computational design for Architecture today aim to automate or bypass the production of construction documents as a means of freeing designers from the sticky and inconvenient contingencies of physical matter. This approach has yielded promising questions and applications, but is based on two related assumptions that often go unnoticed and that I wish to confront: 1. Designers are more creative if the simulations they rely on engage only with the superficial aspects of the objects they design (rather than with their structural and material-specific behaviors) and 2. The symbolic 3-D environments available in current design software are the ideal media for design because of their free nature as modeling spaces. These two assumptions are discussed both as cultural traits and in their relation to digital design technologies. The work presented is a step towards the far-sighted goal of answering the question: how can computation enable new kinds of dialogue between designer, design media and construction in a design process? In concrete, this paper proposes a critical framework for discussing contemporary digital design practices as a continuity –rather than as a rupture- of a long-standing tradition in architecture of separating design and construction.

title	From Modeling to Collective Digital Fabrication: Experience of the "Banco Cabaça"
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 543–554
summary	This paper presents an experience of collective digital fabrication and parametric modeling of furniture made with recycled plastic waste, inspired by natural elements of the Brazilian northeast. In addition to conventional joinery techniques, we highlight the technologies of rapid prototyping (PR) and digital fabrication (FD) (Volpato, 2007, Pupo, 2008; Pupo, 2009); as tools that promote a paradigm shift, both in the design process and in production and materialization (Kolarevic, 2005), allowing recycled plastic to have new applications. We started with a brief review of digital fabrication processes in Brazil, emphasizing collaboration in design and execution. Then, we contain the recycling of plastic and the need for actions for its best destination. Finally, we present a sustainable and collaborative design experience: the modeling and digital fabrication of furniture, entirely produced from recycled plastic, called “Banco Cabaça”.
