title CAD Smart Objects: Potentials and Limitations

summary For many years, CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful symbols. These entities only represented the geometrical aspect of the design, but never had knowledge of what they are, or how to behave. With the new CAD systems, this concept has changed into the smart CAD objects. The smart objects will automatically provide all the data related to it: geometry, materials, specifications, price, as well as manufacturers and theoretically any related data. Creating new objects is not an easy straightforward job, and requires more programming skills than previously needed. Taking into consideration the relative difficulties in learning to modify and create new CAD objects, this might lead to a new branch of learning, as the architecture students might not only need to learn how to use the CAD packages but also how to program it in a way that makes them capable of doing what they want rather than doing what the package allow them to do.

title The Level of Knowledge of CAD Objects within the Building Information Model
source Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 173-177
summary The first generation of CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful graphics symbols. These entities only represented the geometrical properties of the architectural elements. With the present emerging generation of CAD systems, a new concept shifts a drawing-based model into a Building Information Model with the potential of modeling true architectural objects. Theoretically, these CAD objects will provide all related data to the designer describing the geometry, as well as any related data associated with how the object is actually used. The knowledge required to support an object should have structure to it. Different levels of knowledge need to be included, such as the geometrical information, which should be flexible enough to accommodate any type of shape and modification while keeping the object’s integrity as a unit and maintaining its relations to other objects. The CAD object concept, as remarkable as it is, might also have potential problems. It has some implications over the design process, as well as the architectural profession itself.

title Cellular Texture Generator for Architectural Models
source University of Texas at Arlington, Department of Computer Science and Engineering
summary Cellular materials are used extensively in architectural settings. These materials usually have well defined geometry such as brick, stone and tiles. Patterns created with cellular materials are mostly the product of an intuitive design process that goes through cycles of synthesis and reflection until reaching final solution. Therefore interactivity is critical to intuitive designs. This paper presents a system that enables interactive creation of 3D cellular textures. It recognizes critical design areas that can have special design consideration such as edges. The system makes use of existing graphic engines and provides an intuitive interface to create patterns interactively. Rendering time is also considered through defining multiple levels of details for cells so it looks convincing in different scales. The paper presents results with an implementation of cellular texture generation system. It also shows some examples of brick walls generated with this implementation.

title Tangible Design Media: Toward An Interactive CAD Platform
source International Journal of Architectural Computing vol. 1 - no. 2
summary This paper presents an interactive CAD platform that uses a tangible user interface to visualize and modify 3D geometry through manipulation of physical artifacts.The tangible user interface attempts to move away from the commonly used non-intuitive desktop CAD environment to a 3D CAD environment that more accurately mimics traditional desktop drawing and pin-up situations. An important goal is to reduce the apparent complexity of CAD user interfaces and reduce the cognitive load on designers. Opportunities for extending tangible design media toward an interactive CAD platform are discussed.

summary We describe a lighting design system driven by sketching on 3D virtual models. Conventional lighting design tools simulate the lighting effects of design decisions such as window locations, surface treatments, and fixture placement. Light Pen takes the inverse approach by allowing the designer to indicate desired illumination on a 3D model. This serves as input to a knowledge-based lighting design system, which recommends what lights to use and where to place them, based on the designer's expressed intentions and on the geometry of the space.

title Types and precedents in design guidance
source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 653-658
summary In recent years Dutch secondary education has been undergoing a fundamental change due to the introduction of new didactic approaches which relate strongly to ongoing social and technological developments. This affects existing school buildings, the majority of which is quite conventional in spatial terms and is characterized by limited flexibility and transformability. Consequently, most schools require extensive modifications in their spatial and building structure. The requirements underlying these modifications are not stable. Many schools have become interested in experimental ideas that may require inevitably further changes in the buildings. The paper considers the continuous transformation of Dutch school buildings with respect to their typology: by correlating new design briefs to building types rather than their instances we arrive at general guidelines that can be easily adapted to specific cases. To achieve this, the types are analysed with respect to geometry, topology and zoning. The results of the analysis describe the affordances of each type in terms of general flexibility, transformability and adaptability, as well as in relation to generic briefs. They also provide an explanation of the historical evolution of the types and the means for relating primary characteristics to local configurations, thereby allowing the accurate description of hybrid instances. The descriptions and analysis of buildings are organized into a polyhierarchical multilevel database that supports typological abstraction and offers several starting points (at various abstraction levels) for matching a new brief to an existing building. This enriches the development of the brief or a design solution with explicit, specific information derived from concrete precedents with known form, structure, behaviour and performance.

title The Parametric Bridge: Connecting Digital Design Techniques in Architecture And Engineering

summary New design opportunities that are facilitated by cross-disciplinary collaboration in both practice and research are available through the use of high level design software that simultaneously offers real time access to both analysis and design geometry in shared three-dimensional digital models. Here we present a collaborative research project between architects and structural engineers for the design of a pedestrian bridge, conceived to test current digital design processes in architectural and structural engineering practice with those in research through the use of models of parametrically defined associative geometry. In this project, the digital model’s architectural design geometry was constrained by the bridge’s fabrication methods and linked with its engineering analysis. Iterations of the design geometry were then optimised or ‘solved’ to produce variations according to the design parameters offered up for change. The shift of the professions from the plane to digital space exposes the possibilities of new design techniques with the exchange of design parameters potentially operating as a digital dialogue between the disciplines—a kind of digital version of Antoni Gaudi’s funicular hanging model—a metaphor of the digital space that has been developed for this project.

title Materials in Architectural Design Education Software: A Case Study
source International Journal of Architectural Computing vol. 1 - no. 1
summary Most CAAD software in use for architectural education relies heavily on abstract geometry manipulation to create architectural form. Building materials are usually applied as finishing textures to complement the visual effect of the geometry. This paper investigates the limitations of commonly used CAAD software in terms of encouraging an intuitive thinking about the physical characteristics of building materials in the context of the educational design studio. The importance of the link between representation and creativity is noted. In order to sample the current functionality of typical software used in architectural education a case study involving 80 first year architecture students is presented.These outcomes are discussed and the possibility for new or extended software features are suggested. The paper concludes with an argument for design software that redresses the balance between geometry and materials in architectural design education.

title Architectural Design and Digital Paradigm: from Renaissance Models to Digital Architecture

summary Means of expression have always affected our ways of thinking. Designers, who have to interpret signs, languages, and evolution in order to translate into an organised “form” the recurring problems and values of mankind, have left thoughts, projects and wishes to the study of representational techniques. In this way, they have also disclosed a unique view of reality and at the same time a “way of being” towards the meaning of design itself. In the relationship between architecture and representational techniques, Brunelleschi said that “perspicere” was no longer just the science of optics, but also the science that contained the lines of research on geometry and shape that he was the first to exploit in design. Centuries later, in the axonometric representation advocated by De Stijl and intended for factories and industries, the object, shown in all its parts, easy to reconstruct even in the space to which it referred, revealed with extreme clarity the mass-production building and assembly materials and systems. Digital representational media make a great entrance in the heuristic process, invalidate all signs, and promote its quality. The result is an ever-changing, computerised architecture, dominated by curvilinear, wavy shapes that flow from a generative process made of the deformations, additions, and interference of different volumes.

title Knowledge Model for Cultural Analogy in Design and Design Education
source LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
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.

source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 553-560
summary Generative design methods are capable of generating concepts and stimulating solutions based on robust and rigorous models of design conditions, design languages and design performance. The computer now becomes a design generator in addition to its more conventional role as draftsperson, visualizor, data checker and performance analyst. Motivated by the challenge to enable designers to easily develop meaningful input models of design intent to make best use of a structural generative method, this paper describes an initial combination of a generative design tool, eifForm, and an associative modeling system, Custom Objects, through the use of XML models. The current combined use is illustrated through an example involving generation of a set of 20 interrelated roof trusses with seven unique spans initiated by a parametric model of a saddle shaped stadium roof in Custom Objects. The paper concludes with a discussion of the synergies between associative modeling and generative systems and identifies future extensions aimed to exploit these synergies towards integrated performance-based generative design tools.

title Discussing Image-Based Modeling Technology for 3D Digital Archival of Physical Architecture Models
source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 373-380
summary Besides drawings, physical models are important forms of representation commonly used for architectural design. They can serve as a useful resource for teaching and research, provided there is a proper archiving system that allows easy retrieval. Architectural models in 3D digital format seem to be able to overcome the limitation of physical constraints – they can be easily accessed anytime and anywhere over the Internet. The most common way of 3D model documentation is through geometric-based 3D CAD software. Image-based modeling (IM) allows the 3D digital model to be created from photographic images. Debevec (1998) investigated the hybrid geometry- and image-based approach whilst Tsou (2002) and Hawkins (2001) focused on the application of IM for GIS and digitizing cultural artifacts respectively. This paper aims to compare physical models and their IM counterparts in terms of communication of vital architectural information. Experiments were conducted to evaluate the extent the IM model resembled the physical predecessor in terms of its geometry and visual appearance qualities/faithfulness. A survey was subsequently carried out to compare their performance in terms of the communication of vital architectural information about building designs to the observers. The tabulated results were then examined to help understand the opportunities and weakness of IM for 3D archival of physical architecture models

summary We present as an example a story entitled "Invisible Cities" by Italo Calvino in which the author describes an imaginary city. Appealing to mathematical concepts, students seek to design a type of city or architectural space, arising from each student's interpretation of the text. Here, Literature, Design and Mathematics form a framework in which each discipline justifies the presence of the others. In our private case the need of an evolution of the language is presented besides by means of the use of the Digital Graphic.

summary This paper applies the concept of fault tolerance to staircase layout plan. Fire or smoke may cause some staircases in a building inaccessible. We argue that architects should assess the result from the possible fault of vertical routes. The capability of tolerating staircase faults depends on space usage, arrangement, and pedestrian attributes. In this study, a mathematical model is constructed. For analysing pedestrian's movement in interior space, we employ Monte Carol simulation and Agent-Based Modelling method in a CAAD environment. It helps us to visualise the dynamic process of agent's evacuation process, and to test the problem of possible staircase faults. Finally, a case study brings some important discoveries.

summary Tensegrity, defined as “tensional integrity,” is central to the design of a semi-open exhibition space that was submitted as an entry to the international competition for the design of “Ephemeral Structures for the City of Athens,” in the context of the 2004 Olympic Games. The main feature of the proposed exhibition space is a vaulted dome composed of interconnected detachable and deployable tensegrity units. The most challenging aspect in the design of the tensegrity vault was the generation of alternative spatial configurations for form exploration and study. For this purpose a mathematical code has been developed that links all the parameters that affect the design of tensegrity vaults. The code also allows for the parametric graphical generation of the vault by displaying geometric information in a 3D environment. This paper discusses the geometric basis of the code and its usefulness in the morphological study of the tensegrity vaulted dome for the proposed ephemeral structure. The mathematical code has been shown to significantly facilitate the study of various preliminary configurations of tensegrity vaulted structures.

summary Schools of architecture offer admission based on a score system that combines school grade point average (GPA) and standardized testing. Unfortunately, GPA values can give an indication on the academic aptitude of the student but they tend to fall short on describing the potential of the student as a designer. The same may be said of standardized tests that address general verbal, mathematical and analytical skills but lack an adequate framework for measuring all the skills that aid us in performing design processes. This paper will elaborate on the feasibility of developing an on-line testing environment that may address the assessment of fundamental 3-dimentional skills as an additional indicator of potential success in the field of architecture.

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 This paper introduces the concepts of situatedness and constructive memory as the foundations of situated computing. The difference is between encoding all knowledge prior to its use and allowing the knowledge to be developed and grounded in the interaction between the external world and the designer/tool. The paper elaborates these concepts and concludes with a discussion of the implication of situated computing on computational models of designing and on the development of adaptive design tools.

source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 292-301
summary This paper forms an update to the paper presented ar eCAADe 2003, in Graz. It is a summary of a project which aim is to suggest an alternate methodology for utilizing additive Solid Freeform Fabrication (more commonly known as Rapid Prototyping), for the conceptualization and fabrication of design and architecture. It plans to do so by establishing a methodology that is innate and a direct reflection of the additive SFF production process. The project also aims to address the seemingly divisive discrepancy between the process of digitally conceiving a design and the intrinsically somatic way we perceive it. Whereas the paper in Graz introduced the conceptual foundations and the taxonomy of the project, the aim in this years paper is to present some of the realized designs and discuss, in brief, how what has been learnt could be furthered as the project proceeds. The three designs described in more detail in the paper, all catalyzed by a specific sensory notion, would have been very difficult, if not impossible, to fabricate by any other means than additive Solid Freeform Fabrication.

title Post-spatial Architectures: The Emergence of Time-like Parametric Worlds
source SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary A new trend is emerging in architecture today: dynamic and time-like architectures (a term derived from the language of Theory of Relativity) that are capable of moving, flexing and reconfiguring themselves through globally networked control mechanisms are emerging. Such buildings maybe "plugged into" the information networks and can be manipulated through remote interaction. Architecture can be published, literally. At this time there is no single theoretical framework available to address such architectural efforts and the paper is aimed at providing a framework under the rubric of "Time-like Architectures". The paper addresses the unprecedented transformation of the spatial and temporal foundations of architecture by a convergence of two technological developments: global real-time information networks and kinetic, pneumatic tectonics. Envisioned and in some cases built by a group of avant-garde architects, time-like architectures are poised to become a norm in a not too distant future. The paper will identify, define and outline few time-like works. The paper will also outline the historical, theoretical and ethical relationships between post-spatial (author's term), post-modern and modern architectures using Charles Jencks' structuralist classification, The Evolutionary Tree.
