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

title	Morphological transformations in Brazilian peripheral areas: a case study of the Vila Cabral neighborhood at Campina Grande-PB
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 112-119
summary	This article describes an analysis of the morphological changes between 2005 and 2020 in the Vila Cabral neighborhood, located on the outskirts of the Brazilian city of Campina Grande. The research was developed in two different analytical scenarios, adopting the algorithmic- parametric computational implementation as a methodology, and applying the following procedures: (i) formal decomposition of a sample of the urban fabric; (ii) visibility graph analysis (VGA); (iii) analysis of the diversity of uses and (iv) analysis of urban density (populational and built). The study demonstrated that the association of different urban analysis tools strengthens decision-making in the context of evidence-based urban design.

summary	It is the thesis of this paper, that the application of a parametric design approach to urban design has great potentials for improving the systematic testing and subsequent argumentation for urban design proposals. Parametric design has so far mainly been applied to engineering. However, the ‘components’ constituting an urban design also share similarities that may be defined parametrically. Aspects such as density, use, mix, form, space, and typology may all be defined parametrically. By doing so, it is possible to not only perform a systematic de-sign process, but also to evaluate the pros and cons of scenarios with different parametric settings. On the basis of a theoretical discussion, followed by a case study in the form of a student workshop, the paper will discuss the nature and scope of parametric urban design, draw some preliminary conclusions, and outline some possible perspectives for the development of parametric urban design.

summary	This paper presents a parametric shape grammar that explains the generation of the structural forms of the Spanish designer Santiago Calatrava. The shape grammar is divided into two separate grammars a lower level grammar and a higher level grammar. The lower level or first grammar is composed of rules to generate a “fundamental unit” design, which has the characteristic to be a single component with non-repetitive parts that becomes the primitive object of the design. The higher level or second grammar is composed of rules that generate the overall design by recursive application of Euclidean transformations to the fundamental unit. We concentrate our discussion on the higher level or second grammar to demonstrate the process of generating complex designs by application of simple rules.

summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wireframes, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.

title	Skin That Fits: Designing and constructing cladding systems with as-built structural data
doi	https://doi.org/10.52842/conf.acadia.2005.236
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. 236-245
summary	An awkward interface exists between the structure and skin of complex architecture. The primary structure is typically allowed much higher tolerance ranges than that of the cladding industry, due primarily to the delicate nature of the building envelope which, above all, must prevent water penetration and meet the aesthetic requirements of the architect and client. As architecture has integrated advanced design and fabrication techniques to realize increasingly complex shapes, this problem has been aggravated because of the tangency requirements for high gloss curved finish surfaces and the larger variations found with rolled steel columns and undulating concrete forms. To date, most innovations in this area have been focused upon mechanical connections that can be adjusted and shimmed, thus requiring increased design engineering and on-site labor costs for effective implementation. It would be preferable to manufacture cladding components that are properly adjusted to the actual site conditions, negating the need to predict and accommodate potential dimensional variation with complex connections. The research provides a model for implementing long distance laser scanning technology to facilitate a real-time parametric BIM, herein called an Isomodel.

title	Multi-user virtual worlds: 3D interactive visualization in synthetic environments for design workshops
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 344-349
summary	The goal of this research is to describe a methodology of architectural design by using digital technology with three-dimensional interactive simulation in multi-user virtual worlds. In addition, this study will focus on the application of this method in the workshops at the School of Architecture in the University of Zulia. With this proposal, it is possible to integrate many users, in real time, from different locations on the same virtual world in Internet. In the same way, each visitor is able to interact and modify the virtual world using virtual menus while sharing ideas or modifications regarding the design of the project. This strategy allows modeling, visualizing, developing and evaluating the designed projects during the conceptual and parametric phase in the process of design. This application is a powerful tool to develop creativity and skills of spatial perception among the students. [Full paper in Spanish]

title	BEYOND MODELLING: AVANT-GARDE COMPUTER TECHNIQUES IN RESIDENTIAL BUILDINGS.
source	I Jornadas de Investigacion en Construccion, Madrid, 2-4 June, 2005.
summary	If the result of computer innovations can be interpreted as an emerging “difference” in the quality of constructed space, then in order to truly understand what future applications may be regarding architecture at present, we should look at what advanced functions are available in the process of designing forms and space (DeLuca and Nardini, 2002). Recently the so called parametric approach, a technique for describing a large class of designs with a small description in programming code, has become a focus of attention in architectural computing. In this paper, we reflect on the current use of parametric tools using real case studies as well as our own proof of concept parametric programmes and report on how the avant-garde computer techniques may help to increase the quality of residential building.

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”.

title	Analysis of the possibilities offered by the application of parametric modeling technologies in the design processes shared between architects and industrial designers: The prefabricated house case.
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 300-303
summary	Traditionally, the teaching of digital design systems has been focused on the operative learning of software. However, this almost exclusively technical approach has leaded to a partial view of these systems, as well suited platforms to exploration of project’s possibilities. Consequently their relevance as a base for project representation and therefore as a useful instrument for conceptual exploration for design and experimental research of their processes have been undervalued. On the other hand, this restrictive perspective results in an important waste of the teaching possibilities lying in CAD software related with interdisciplinary teamwork. The following academic experience obeys to a new insight of how to teach these tools, based upon problem solving in Design by interdisciplinary students work teams from Architecture and Industrial Design. In this bet, the learning process is flexible, shared and collaborative, according to the requirements of each project, powered by the commitment of facing common goals. [Full paper in Spanish]

summary	This paper introduces a generative design tool for the early design phases. The tool is a prototype plug-in for 3D studio max, based on 3dmax script language. This plug-in generates form alternatives with symbolic representations. Designer sets max and min size values and positional relation rules for different sub-parts of the whole form. After the generation process designers can apply transformation modifiers and materials built in 3D Studio Max to the picked alternative. And get possible 3D form solutions that meet with the constraints of the design problem.

summary	The study described in this paper evolves within the larger context of a research aimed at inquiring into analogies between architecture and nature, and more specifically between architecture and biology. Biology is a recursive source of architectural inspiration due to the tight relationship between form and function, the natural balance of forces and the corresponding geometric solutions found in living beings. Roughly, one can classify historical analogies between architecture and biology into two main categories. The first tries to mimic biological forms and the second biological processes. The specific goal of the described study is to find how new technologies can redefine and support the process of constructing such analogies. It uses as a case study a tower project designed by the architect Manuel Gausa (ACTAR, Barcelona) called Tornado Tower because of its complex shape inspired in the frozen form of a tornado. Due to the geometric irregularities of the tower, Gausa’s team had difficulties in designing it, especially because solving the structural problems required constant redrawing. This paper describes the first part of the study which primary goal was to conceive a parametric program that encoded the overall shape of the Tornado Tower. The idea was to use the program to simplify the drawing process. This required a mathematical study of spirals and helices which are at the conceptual basis of the external structure and shape of the tower. However, the program encodes not only the shape of Gausa’s tower, but also the shapes of other buildings with conceptual similarities. Such class of shapes is very recurrent in nature with different scales and with different utilities. Therefore, one can argue that the program makes a mathematical connection between a given natural class of shapes and architecture. The second part of the study will be devoted to extending the program with a genetic algorithm with the goal of guiding the generation of solutions taking into account their structural fitness. This way, the analogy with genetic procedures will be emphasized by the study of the evolution of forms and its limits of feasibility. In summary, the bionic shape analogy is made by the generation of mimetic natural forms and a genetic process analogy starts with the parametric treatment of shape based on code manipulations. At the end the program will establish an analogy between architecture and biology both terms of form and process.

title	Designing Continuous ComplexCurved Structures to be Fabricated from Standard Flat Sheets
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 114-119
summary	This paper explains how complex curved structures can be constructed from flat standard panels. The main objective is to link both design techniques and digital fabrication methods to solve a recurrent problem in contemporary architectural design, building double curved structures. Secondly, it achieves this by using regular fabrication methods and standard construction materials, available and affordable for Latin-American countries. It describes the processes of programming a set of computational tools to study and develop designs to fabricate continuous complex curved structures. I will describe this through a series of experiments, using parametric design environments and scripted routines for CAD software to implement certain techniques to fabricate these designs using rapid prototyping machines. I compare different fabrication methods using computer numerically controlled machines, used to process these flat panels to obtain certain properties, allowing them to bend, twist, fold or stretch achieving these complex forms.

title	ICHTYOMORPH - Design and development of a fish-skin double façade system for freeform super tall buildings using Parametric Design Tools
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 144-149
summary	Parametric design implies a whole new paradigm of non standard design through the propagation of the difference, the repetition of variation. The ability to control variation and adaptation to local conditions allows more precise yet complex designs. This paper describes a research project designing double skin façade systems for tall buildings using a parametric approach. These designs are tested later through rapid prototyping techniques. This research aims its design towards an adjustable façade structure, articulated according to various complex geometrical conditions on the façade of a building. The skin is conceived as a light, flexible, reconfigurable composition responding to different criteria regarding the design, its environment or the program. It achieves this through different levels of control on different scales of the project, by embedding several layers of parametric features, which are nested one inside the other, in order to produce the overall rainscreen surface of the tower.

The envelope will be highlighted as a filter mediating micro and macro environmental conditions. The starting point will be the observation of a natural/ biological example in which the distinction between structure and skin is dissolved, using it in a new instrumental way. Furthermore, it will be developed a new generative System through the application of parametric design. The new design will be constructed through the use of CNC machinery (CAD-CAM).

title	Design Using Evolutionary Optimisation and Associative Geometry
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 243-254
summary	This paper describes the usage of parametric design and evolutionary optimisation techniques in architect-engineer collaborations. It discusses the apparent challenges in setting up a trans-disciplinary working-platform that cuts across profession-specific boundaries and negotiates between the otherwise distinct work-methodologies through the use of intelligent CAAD applications. Two approaches to architectural form finding have been combined in this research. The first, parametric design, uses a proprietary package as a key element to the organisation and reorganisation of architectural design. By doing so, it is providing it with intrinsic flexibility allowing designers to go beyond form and accommodate performance data for versioning. The second, ESO (Evolutionary Structural Optimisation), is an engineering tool based on the use of finite element analysis (FEA) capable of optimising the formal geometry of an object to obtain minimum volume under even stress-distribution through an iterative design process. In undertaking this research it became apparent that different levels of resolution need to be addressed in the form-finding process in order to investigate the full potential of the interactive use of parametric design and evolutionary optimisation. The case studies reflect this diversity and demonstrate more successes, limitations and future challenges within the transdisciplinary, collaborative effort.

Furthermore, it lays out how constraints are employed in the construction and exploration of a model’s design space. The paper places this approach within the larger context of design exploration using computational and conceptual representations of design. Four general constraint types are identified and examples from several workshops and design studios are presented for each of the constraint types. The examples range from product design to structural design to fabrication issues in architecture. Based on a review of the literature the most common constraints are of geometric, topologic, functional, and quantitative type. Based on the case studies the paper describes how the different types of constraints can be used as design drivers and help in the exploration of solution space. In conclusion the paper identifies the addition of bi-directional properties to constraint modeling as the next challenge in improving the application of constraint modeling in design exploration. Furthermore, the paper demonstrates the necessity to develop better constraint models for cross domain design.
