title	Using Case-Based Reasoning to Aid Sustainable Design
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 241-246
summary	Since so far there exists only one planet, sustainable design is considered the (ethical) future in all fields of design. Although both architecture and construction are being considered major emitters of green house gases, a wise design not only can lead to minimizing this impact but it can also lead to restoring and regenerating the environment to a sustainable state. This paper presents an on-going research that aims at simplifying the elements and facilitating the process of sustainable design by using case-based reasoning. This is achieved through learning from past experiences; both good and bad ones, by providing a database application with a process-friendly interface which divides the main pillars of sustainable design into categories. Each building contains different stories related to different sustainable related issues. Each story can be repeated in /linked to many buildings. By providing designers with those past experiences, it is believed that deeper-studied designs can be more easily developed. Also a deeper analysis and understanding can be further implemented and produced with less effort for experienced and non-experienced architects in sustainable design. This would also decrease the consumption of time during the design process and encourage even more designers to integrate the sustainability concept into more designs. This research discusses the influence of sustainable design within the architectural domain, and suggests a computer application that aids architects during the preliminary design processes.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

summary	Textiles and architecture share a long, intertwined history from the earliest enclosures to contemporary high-tech tensile structures. In the Four Elements of Architecture, Gottfried Semper (2010) posited wickerwork and carpet enclosures to be the essential origins of architectural space. More recently, architectural designers are capitalizing on the characteristics of textiles that are difficult or impossible to reproduce with other material systems: textiles are pliable, scalable, and materially efficient. As industrial knitting machines join robotic systems in architecture schools with fabrication- forward agendas, much of the recent developments in textile-based projects make use of knitting. In this paper, we propose an alternative textile technique, lacemaking, for architectural fabrication. We present a method for translating traditional lacemaking techniques to an architectural scale and explore its relative advantages over other textiles. In particular, we introduce bobbin lace and describe its steps both in traditional production and at an architectural scale. We use the unique properties of bobbin lace to form workflows for fabrication and computational analysis. An example of computational analysis demonstrates the ability to optimize lace-based designs towards particular labor objectives. We discuss opportunities for automation and consider the broader implications of understanding a material system relative to the cost of labor to produce designs using it.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title	Double Loops Parametric Design of Surface Steel Structure Based on Performance and Fabrication

summary	In intelligent epoch, automatic parameter design systems reduce the requirements of the skills needed to create objects. The creator only needs to select the most perceptual primitive form to automatically generate the data system that iterates to the most efficient solution. In this paper, a method of combining performance driven optimization with parametric design is proposed. The iterative evolution is under the control of performance loop and fabrication loop, which makes all the data provided by parametric design in a practical project available for exploring structural analysis and digital prefabrication. Related to the case of surface steel structure, parametric optimization is not limited to a set of shape types or design problems, it would be based on the generality and built-in characteristics of parametric modelling environment in the most convenient and flexible way. (Rolvink et al. 2010)And the given parameters would be fed back on geometric structure, performance indicators, and design variables, so that designers can easily and effectively coordinate and try different solutions. The system transforms the generated data into machine language so that the process including design, analysis, manufacturing, and construction can maintain the orthogonal persistence of the data.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

title	A Computational Medium for the Conceptual Design of Mix-Use Projects
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 109-116
summary	Mix use development is receiving wide attention for its unique sustainable benefits. Nevertheless, the planning and designing of successful mixed use projects in today's environment is a complex matrix of skill sets and necessary collaborations between various stakeholders and design professionals. From a design point of view, architects are required to manage and coordinate large information sets, which are many time at odds with one another. The expansive space of knowledge and information is at its best vague and substantially ill-structured. A situation that continues to overburden architects mental and intellectual ability to understand, address and communicate the design issue. In the face of this complex condition, designers are gravitating towards information modeling to manage and organize the expansive data. However, is becoming increasingly evident that current building information modeling applications are less suited for early design activity due to their interrupted and rigid workflows. Against this background, this paper presents a theoretical framework for a computational medium to support the designer during early phases of exploring and investigating design alternatives for mix-use projects. The focus is on the conjecture between programming and conceptual design phase; when uncertainty and ambiguity as at its maximum, and the absence of computational support continues to be the norm. It must be noted however, the aim of the medium is not to formulate or automate design answers. Rather, to support designers by augmenting and enhancing their ability to interpret, understand, and communicate the diverse and multi-faceted design issue. In literature on interpretation, Hans-Georg Gadamer explains that understanding is contingent on an act of construction. To understand something is to construct it. In light of this explanation. To help designers understand the design issue, is to help them construct it. To this end, the computational medium discussed in this paper is conceived to model (construct) the mix-use architectural program. In effect, turning it into a dynamic and interactive information model in the form of a graph (network). This is an important development because it will enable an entirely new level of interaction between the designer and the design-problem. It will allow the designer to gather, view, query and repurpose the information in novel ways. It will offer the designer a new context to foster knowledge and understanding about the ill-structured and vague design issue. Additionally, the medium would serve well to communicate and share knowledge between the various stakeholders and design professionals. Central to the discussion are two questions: First, how can architects model the design program using a graph? Second, what is the nature of the proposed computational medium; namely, its components and defining properties?

title	Integrative Design Strategies for Multimedia in Architecture
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 372-379

summary	Multidisciplinary efforts that have shaped the current integration of multimedia into architectural spaces have primarily been conducted by collaborative efforts among art, engineering, interaction design, informatics and software programming. These collaborations have focused on the complexities of designing for applications of multimedia in specific real world contexts. Outside a small but growing number of researchers and practitioners, architects have been largely absent from these efforts. This has resulted in projects that deal primarily with developing technologies augmenting existing architectural environments. (Greenfield and Shepard 2007)This paper examines the potential of multimedia and architecture integration to create new possibilities for architectural space. Established practices of constructing architecture suggest creating space by conventional architectural means. On the other hand, multimedia influences and their effect on the tectonics, topos and typos (Frampton 2001) of an architectural space (‘multimedia effects matrix’) suggest new modes of shaping space. It is proposed that correlations exist between those two that could inform unified design strategies. Case study analyses were conducted examining five works of interactive spaces and multimedia installation artworks, selected from an initial larger study of 25 works. Each case study investigated the means of shaping space employed, according to both conventional architectural practices and the principles of multimedia influence (in reference to the ‘multimedia effects matrix’) (James and Nagasaka 2010, 278-285). Findings from the case studies suggest strong correlations between the two approaches to spatial construction. To indicate these correlations, this paper presents five speculative integrative design strategies derived from the case studies, intended to inform future architectural design practice.

title	Multi-touch - the future of design interaction
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. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

summary	This paper is a presentation of the preliminary framework for the design and fabrication of the soft-skin. Today, the digital technology applied in the architecture field is everywhere. However, there are still lots of fantastic free form architecture uncompleted and remained on the paper architecture or only the digital visual simulated model. Until now, most of the finished free form cases are consisted of the skin and bones, or only the bones. The complete soft-skin cases without the bones are fewer and the process remains untold. Based on the parametric environments and biology, how might you design a free form without the bones? How could you make the soft skin stand up? The research starts a series of exploration of the design and fabrication for the soft skin, and seeks to propose the preliminary framework as a helpful reference for the designers who deal with the soft skin project.

title	ViSA: A Parametric Design Modeling Method to Enhance Visual Sensitivity Control and Analysis
source	International Journal of Architectural Computing vol. 8 - no. 4, p. 461
summary	The ability of parametric computer-aided design systems to generate models rapidly enables designers to explore the downstream impacts of changes to key design parameters. However, the typical modeling functions provided in the parametric systems can become insufficient when such exploration is needed for increasingly complex parametric design models. Main challenges for exploration that we observed are control and analysis of changes on the design model and in particular, when they are introduced continuously. The system interfaces and the human-visual perception system alleviate these challenges. In this study, we demonstrate ViSA, a Visual Sensitivity Analysis method that aims to make the effects of change within a parametric model controllable, measurable and apparent for designers. The approach aims to improve visually analyzing the sensitivity of a design model to planned parametric changes. The method proposes customizable control and visualization features in the model that are decoupled from each other at the design level, while providing interfaces between them through parametric associations. We present findings from our case studies in addition to the results of a user study demonstrating the applicability and limitations of the proposed method.

title	Quantum architecture: an indeterministic and interactive computational design system
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 619-628
doi	https://doi.org/10.52842/conf.caadria.2010.619
summary	The evolution of computational design technique from mere substitution of hand drawing to customised design algorithms exhibiting a certain degree of intelligence, naturally opens up a new research frontier that studies the relationship between designers and customized design algorithms. Most of current customised architecture design algorithm adopts a deterministic paradigm to raise their design questions, that is to say, given the explicit rules and parameters, only one solution is allowed at each discrete computation step. Due to this deterministic nature, an intuitive and efficient communication between design algorithm and designer is hard to achieve, as there is almost no space for designer to step into the running generative process. This lack of progressive communication channels and the inefficiency of translating perceptual judgment into computer language directly results in the unconscious rejection of non-parameterisable design factors like intuition, aesthetic judgment and associational reasoning that are essential to any design activity. This paper introduces the quantum design paradigm as alternative computation paradigm for constructing an interactive and intuitive design system. An algorithm prototype, probability field, will be introduced to illustrate the logic and possible application of the proposed quantum design paradigm.

title	Patterns, heuristics for architectural design support: making use of evolutionary modelling in design

summary	Software used by architectural and industrial designers has shifted from becoming a tool for drafting, towards use in verification, simulation, project management and remote project sharing. In more advanced models, design parameters for the designed object can be adjusted so that a family of variations can be produced rapidly. With the advances in computer aided design (CAD) technology, design options can now be generated and analyzed in real time. However the use of digital tools to support design as an activity is still at an early stage and has largely been limited in functionality with regard to the design process. To date, major CAD vendors have not developed an integrated tool that is able to leverage specialised design knowledge from various discipline domains (known as expert knowledge systems) as well as to support the creation of design alternatives that satisfy different forms of constraints. We propose that evolutionary computing and machine learning be linked with parametric design techniques in order to monitor a designer’s cognition and intent based on their design history. This will lead to results that impact future work on design support systems which are capable of supporting implicit constraint and problem definition for wicked problems that are difficult to quantify.

summary	Design and presentation of new furniture is today a great challenge that requires a large amount of resources: exhibition space, photographic studios, physical prototypes, etc. In this paper we present a new RTR framework RTR-based that allows a more sustainable design and communication process. The framework is addressed to furniture designers, interior designers, furniture companies and presents techniques and methods developed to meet the requirement to ensure predictive rendering quality required by the high level furniture industries. Finally, in order to ensure full functionality a number of tools described in the paper were developed.

summary	Nowadays, a large set of involved planning parties are heavily demanded with the definition of holistic in kind requirement specifications for urban planning sites – so called future cities. However, the resulting amountof specifications for a specific building project poses a great challenge to designers and planners especially when it comes to include this information into their design proposals for a sustainable urban development. These design performance criteria are traditionally expressed in textual and numerical planning guidelines and which are making it difficult to establish a comprehensive and holistic view onto the domain itself. Therefore we present in this paper a design guide visualization method to overcome this situation for the evaluation of design specification and urban layouts in a qualitative and quantitative manner.

title	Singapore National Stadium Roof
source	International Journal of Architectural Computing vol. 8 - no. 3, pp. 257-278
summary	The case study focuses on design of the Singapore National Stadium roof and its architectural and structural constraints. The dialog between performance form generation and aesthetics was challenged through several design iterations and is critically reviewed in this paper. The collaboration of engineers and architects gave a form to this significant building that was slightly changed several times due to various conditions. The complex shape of the dome structure was resolved in one parametric model that could react on aesthetical and structural requirements. The landmark roof structure generated in computer had to be evaluated by designers and presented to decision making bodies.

summary	Graphic designers always take both time and efforts when they are creating a decorative pattern with complicated curves and a great deal of motifs. Although there are many sourcebooks of decorative patterns, the satisfaction of the results couldn’t accomplish with designer’s requirements. Thus, graphic designers need a faster and easier system to create decorative patterns in classical style. There are a few effiencient methods to analysis curves and surfaces in the development of shape grammars. The purpose of this research is to develop Vine Grammar based on shape grammars. The vine grammar analyses principles hidden in the language of deisgn works to create the order, then generates design by using Bézier curves. This research also presents the development of a decorative pattern generative system called Shlishi by using FLASH Action Script 2.0. The grammar can be applied with computers and to verify rules quickly by Shlishi. The intention of this research is to make graphic designers to use these rules to create decorative patterns of plants in classic style and to produce satisfactory results for designer more efficiently or to make the results the source materials for the follow-up design works.

summary	Parametric software has fundamentally changed the way in which architecture is conceptualized, developed and even constructed. The ability to assign parameters or numeric variables to specific portions of a project has allowed designers the potential to test variations of their design. Small changes to a single parameter can have an exponential effect on the designed object and alter its appearance beyond original preconceptions in both positive and negative ways. Parametric software also has the ability to constrain or restrict geometry to set values, parameters or conditions. This has the benefit of allowing portions of a form to remain constant or unchanged while simultaneously allowing for a great degree of flexibility in response to a design intent. Constraining portions of a design allows architects to respond to existing or unalterable conditions by ""locking down"" information within a project and then explore those portions that can change more freely. This programmed relationship between the parameter and the form, once established, can give the illusion of minimal effort for maximum output. The ease in which geometrical form can be altered and shaped by a single variable can mislead beginning designers into thinking that the software makes these relationships for them. What is hidden, is the programming or connections needed between the parameters and the geometry in order to produce such dramatic change. Finally, thinking parametrically about design reintroduces the concept of a rigorous, intent driven, fabrication oriented practice; a practice lost in a digital era where the novelty of new tools was sufficient to produce new form. Because parametric models must have established relationships to all parts of the design, each component must have a purpose, be well thought out, and have a direct relationship to a real world object. The introduction of parametric design methodologies into an architectural pedagogy reestablishes architectural praxis in an academic setting. Students are taught to design based on creating relationships to connected components; just as they would do in a professional architectural practice. This paper outlines how Digital Project – a parametric based software – was introduced into an academic setting in an attempt reconnect the ideologies of academia with the practicalities of professional practice. In order to take full advantage of Digital Project as a parameter based software, a project that creates modular, flexible geometries was devised. Produced over one semester, the project set out to find ways of controlling designed geometry through variable parameters that allowed the initial module to be instantiated or replicated into a wall condition: maintaining a unified whole of discrete components. This paper outlines this process, the results and how the outcomes demonstrates the parametric ideologies described above.

title	Studying designers’ behaviour in collaborative virtual workspaces using quantitative methods
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 273-282
doi	https://doi.org/10.52842/conf.caadria.2010.273
summary	This paper presents a case study comparing the behaviour of designers in a collaborative 3D virtual environment with those in a face-to-face environment using quantitative tools to examine their design protocols. It starts with depicting a design ontology along with two methods of analysis for this investigation. The results in this case show that the 3D environment increases the designer’s Structure activities. The rate of meaningful design communication is slower than the base-line face-to-face session. This communication reflects the rate of design cognition when the design process is “close coupled”. Reviewing the design protocol suggests that the 3D design session composed of both “loosely coupled” and “close coupled” periods. This is consistent with other studies that 3D collaborative tools may encourage “loosely coupled” design process.
