summary	Architects and designers are normally interested in situations where differences make a difference. This paper presents the results of the developed system of intelligent design agents that supports design exploration and creativity within the domain of architectural shapes. Creativity in architectural design compositions can be viewed as an emergence of new forms and shapes or relationships between forms and shapes from which new concepts can be discovered.

title	New Design Methods for Computer Aided Architectural Design Methodology Teaching
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	Architects and architectural students are exploring new ways of design using Computer Aided Architectural Design software. This exploration is seldom backed up from a design methodological viewpoint. In this paper, a design methodological framework for reflection on innovate design processes by architects that has been used in an educational setting is introduced.The framework leads to highly specific, weak design methods, that clarify the use of the computer in the design process.The framework allows students to grasp new developments, use them in their own design work, and to better reflect on their own position relative to CAAD and architectural design.

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

title	Interactive Mapping between Knowledge Level and Symbol Level with Geometry. A KL-Model for Design Space Exploration
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 157-166
summary	Design space exploration is long-standing motivating ideas in computer-aided design. It realises this vision through a model of design states for making and moving amongst states and an organisation of states into a structure called a design space. Using a design space structuring mechanism based on a subsumption relation, this paper sketches a theory called Geometric Typed Feature Structures (GTFS) to preserve the formal properties of the design space movement algorithms for geometry. It also provides the theory for incorporation of user-guided exploration in the design space. Consequently, the clear division between knowledge level and symbol level, such that functional decomposition •• formal symbol level and design •• model symbol level, disappears. We can therefore use the same subsumption relation to structure the design space exploration interactively. Such interactive mapping between knowledge level and symbol level provides the fine-grained opportunities for user intervention in formal design space movement algorithms. In this paper, we summarize this approach with an example of GTFS subsumption process.

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

doi	https://doi.org/10.52842/conf.caadria.2006.x.r4i
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 597-599
summary	In 1990, due to the traditional architecture design and construction method difficult to build the complicated and non-geometry free-form Fish Structure in Barcelona, architect Frank Gehry started learn from the field of aerospace to utilize CAD/CAM technology in design and manufacture process. He created the free-form fish model in CAD system and exported the digital CAD model data to CAM machine (RP and CNC) to fabricate the design components, and finally assembled on the site. Gehry pioneered in the new digital design process in using CAD/CAM technology or so-called digital fabrication. It becomes an important issue recently as the CAD/CAM technology progressively act as the new digital design media in architectural design and construction process (Ryder et al., 2002; Kolarevic, 2003). Furthermore, in the field of architecture professional, some commercial computer systems had been developed on purpose of standardizes the digital design process in using CAD/CAM fabrication such as Gehry Technologies formed by Gehry Partners; SmartGeometry Group in Europe and Objectile proposed by Bernard Cache. Researchers in the research field like Mark Burry, Larry Sass, Branko Kolarevic, Schodek and others are enthusiastic about the exploration of the role of CAD/CAM fabrication as new design media in design process (Burry, 2002; Schodek et al., 2005; Lee, 2005).

title	Integrating CAD and 3D Virtual Worlds Using Agents and EDM
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 301-312
summary	This paper develops an overall architecture for integrating CAD and virtual worlds. The advantages of having access to the building model in a virtual world include the collaborative nature of the world. The EDM database as an object-oriented database is developed to establish a common object-oriented representation of building model, which can be accessed by both CAD systems and virtual worlds. The integration between CAD systems and an EDM database is implemented through the use of Industry Foundation Classes (IFCs) as an intermediate data model and the communication between the database and virtual worlds is developed through agents.

title	AN ANALYSIS OF PROBLEM FRAMING ACTIVITIES IN DIGITAL VERSUS PAPER MEDIA
source	Architectural Education, Southeast University, Nanjing, China, December 2003, pp. 183-189
summary	Architectural design is described in part as the solving of ill-defined or wicked problems. In these activities, designers are not only simply given well-stated problems but also need to find and formulate problems. This process is called as ‘problem framing’. Paper media have been for many years the design tools used by designers to help them engage, and hence frame, problems. Computer technologies have gained prominence in design processes but have typically been used in discrete problem solving processes or in presentation. It has been stated that problem exploration is more difficult using a computer tool. This attitude has influenced the teaching and use of computers in architectural education. The purpose of this study is to understand how digital and paper media are used respectively in ‘problem framing’ activities in support of students’ design learning. This paper reports a pilot laboratory study to test the validity of a proposed coding scheme comparing design activities using digital and paper media and report initial results of the research. Through this research we wish to gain insight of ways in which students engage in ‘problem framing’ activities using different media and suggest ways in which digital media might better support problem framing activities.

title	A Function - Behaviour - Structure View of Social Situated Design Agents

summary	This paper proposes a comprehensive schema to represent an agent's social knowledge using the Function - Behaviour Structure (FBS) schema. Although this schema has originally been developed to represent knowledge about design objects, it is sufficiently abstract to also describe knowledge about agents. This paper shows how such an FBS view can be useful to support the interaction of situated design agents.

summary	Virtual Architecture is a virtual place that uses the metaphor of architecture and provides an online environment for various human activities. While Virtual Architecture inherits many of the characteristics of physical architecture, it is possible to reconsider the virtual in terms of flexibility and autonomy. This paper presents a Usercentred Virtual Architecture (UcVA) Agent, a kind of rational agent capable of representing a person in virtual worlds and designing virtual worlds based on current needs. The UcVA agent model has a design component that uses the shape grammar formalism. This model and a sample grammar are demonstrated for a meeting room scenario.

title	(Learning from Experience)? Promises, Problems and Side-effects of Case-Based Reasoning in Architectural Design
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	Learning from experience is the essence of Case-Based Reasoning (CBR). Because architects are said to learn design by experience, CBR seemed to hold great promises for their field, which inspired, in the 1990s, the development of various Case-Based Design (CBD) tools. Learning from the experience of developing and using these tools is the objective of this paper. On the one hand, the original expectations seem far from being accomplished today. Reasons for this limited success can be found at three different levels: the cognitive model underlying CBR, the implementation of this model into concrete CBD tools, and the context in which these tools are to be used. On the other hand, CBR research seems to have caused some interesting side effects, such as an increased interest in creativity and copyright, and a re-discovery of the key role that cases play in architectural design.

title	Immersion, Interaction, and Collaboration In Architectural Design Using Gaming Engines
doi	https://doi.org/10.52842/conf.caadria.2003.721
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 721-738
summary	"This paper investigates the role of gaming engines in the architectural design process through the introduction of features such as immersion, interaction and collaboration. While traditional 3D modelling and visualization systems such as 3D Studio MAX and form?Z offer increasingly convincing visual simulations, gaming engines are approaching the visual realism of such systems and are offering additional interactive features that are usually available only in more expensive immersive virtual reality systems . Additionally, the capability to have multiple individuals inhabit and navigate the space offers unique opportunities for collaboration as well as the investigation of human behaviour. Participants with internet access can be invited to access a shared virtual environment. Collaboration among users can be further enhanced by combining immersive navigation with peer-to-peer instant messaging and/or adding a voice channel. This paper analyzes these issues through research summary and the creation and user testing of a prototype based on a publicly available gaming engine. Through a series of assignments within an academic course, students in the school of architecture were asked to iteratively use and test this prototype for the collaborative exploration of designed environments. Students made their environments available for others to navigate in real-time and offer comments. A final design review was conducted in which critics were asked to enter the designed environment, explore it at will and interact with the student as well as others present in the same virtual space. This paper will illustrate some of the student projects and describe the immersive,"

summary	This paper documents the approach, process and results of several architectural design studios where the author introduced science fiction (broadly defined) and three computer experimental form modelers as 'creative stimulants' in the pursuit of Fantastic Architecture. The paper is not about whether architecture students should or should not pursue the design of 'implausible', 'absurd', or even 'bizarre' architecture, but about using a particular strategy as a sincere attempt to stimulate imagination and creativity.

title	Knowledge Model for Cultural Analogy in Design and Design Education

summary	Almost every architect uses analogy while designing. The source of inspiration is nature, technology, geometry, etc., besides the influence of the work of other architects. Analogy in architecture has a close relationship with culture as well. Culture is a dynamic occurrence and evolves by the influence of many aspects such as technological, economical, environmental and social. In the process of design, architects built op knowledge from their own experience and designs, but also from the other designers work. Usually, architects develop this quality and ability during the education, and later by trial and error methodwhile practising the design. This is habitually done based on own conscience, intuition and experience.The developments in ICKT (Information, Communication and Knowledge Technology) as a part of broader technological developments and the ongoing globalisation, influences the culture as a dynamic process and therefore the architecture.. It is necessary to make these influences explicit for their embedding in architectural design education of young professionals. This can be achieved by transferring the resulting knowledge to a knowledge model by using intelligent modelling techniques. The operational aspects of design analogies to be implemented in education, research and the daily practice of designing architects need attention. This paper discusses the operational aspects of cultural analogy in design by using an intelligent computational modelling approach.

summary	The purpose of this study is to present an application of an RP machine in the substantiation of architectural design concepts, using color image mapping to enhance visual details. Related visualization leads to the exploration and comprehension of shapes. Exemplification can be seen in the verification for proofing or documentation of as-built models, such as paper architecture, process modeling, furniture, partitions, and construction details. The influences on architecture reveal issues related to pedagogical exploration, interdisciplinary exploration, reality management, and visual detail and structural detail.

It explores possibilities of using it as a process of architectural shape generation, combined to computer-aided modeling tools and rapid prototyping. It intends to go through two complementary ways of translation between object shape and topology: the making of architectonical objects in topological surfaces and, on the other way, the exploration of topological surfaces as architectonical objects.

source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 569-571
summary	Folding is not only a design operation of shaping but also a philosophy theory from Deleuze (Deleuze 1988) which was adopted by architecture. Basically, folding constitutes to forming and topology, which often delivered a mathematical and philosophical expression in generating 3D architectural form. For instance, the work of Eisenman (Eisenman 2003), Libeskind and Lynn (Lynn 1998), they use folding as inspiration to explore the textural folding and bifurcation meaning in the process of form-making. While exploring the meaning of folding, their ideas are expressed by the form using computational tools. Therefore, if a suitable or inspirable tool like our Folding Space (FoS) could be available, such action –fold can be expressed further in the form exploration process.

summary	In this paper we discuss designing abilities, such as creativity and learning, as abilities that emerge though interaction in cooperative human-machine networks. We concentrate in a design system that can exhibit and support creative behaviour using knowledge learnt through distributed human-machine interaction. In this context, conflict resolution and coordination is a main issue, as well as a main indicator for the creative and adaptive ability of the design system. More specifically, we are going to present a model of coordination developed using learning control and multi-agent systems methodologies and techniques. A prototype system is tested in a virtual collaborative design assignment for simple location and three-dimensional configuration problems.

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