summary	The study is part of a research aims to establish theoretical grounds essential for the development of user efficient design tools for energy-conscious architectural design, based on theories in human factors of intelligent interfaces, problem solving, and architectural design. It starts by reviewing the shortcomings of the current energy design tools, from both architectural design and human factor points of view. It discusses the issues of energy integration with design from three different points of view: architectural, problem-solving, and human factors. It evaluates theoretically the potentials and limitations of the current approaches and technologies in artificial intelligence toward achieving the notion "integrating energy design knowledge into the design process" in practice and education based on research in the area of problem solving and human factors and usability concerns. The study considers the user interface model that is based on the cognitive approach and can be implemented by the hierarchical structure and the object-oriented model, as a promising direction for future development. That is because this model regards the user as the center of the design tool. However, there are still limitations that require extensive research in both theoretical and implementation directions. At the end, the study concludes by discussing the important points for future research.

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.

summary	Describing design as a sequence of steps cannot convey the complexity of social interactions that it embodies. Design is not merely a process, but a co-evolution of efforts and events in various places and times—both synchronous and asynchronous. Designers share their values, effort and expertise within design settings via artifacts that further the design process. Increasingly, these design settings in academia, research, and professional practice combine physical and virtual modalities such as immersion, projection, and a range of interaction technologies. Peter Anders has described such spaces as cybrids: hybrids that integrate virtual and physical space. In these settings, designers use overlapping physical and virtual artifacts and tools to arrive at a co-operative design resolution. Within collaborative design, these artifacts take on an additional role. As embodiments of design ideas and actions, they become media for communication. Donald Schon asserts that design should be considered a form of making, rather than primarily a form of problem solving, information processing or research. Indeed the line separating creation from design is becoming increasingly blurred. For the design artifact itself may become a part of the design proposal—its virtual presence incorporated within a cybrid structure or object. We may in the future see a proliferation of cybrid settings that support collaborative, digital design. The technologies for this already exist in collaborative tools, networked computing, scanning and immersive media. However, it will take a creative vision to see how these disparate tools and devices can integrate within the ideal design setting.

title	Reflections on Computer-Supported Cooperative Design Systems
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. 169-180
summary	Computer-supported cooperative work has come to signify a process by which a computer system supports the activities of geographically dispersed participants and enables them to share ideas and artefacts. This paper aims to dispel this unified approach to the definition of and in turn the design of aids to cooperative work. The paper starts by surveying the history of the field of computer-supported cooperative work and design. Then, the paper presents three tasks and their associated aids. The first system helps designers to create and discuss a hierarchical building program and share schematic drawings. The second system allows a jury to anonymously review a set of submissions. The third system allows a hierarchically organised group of participants to search, retrieve, organise and share a set of digital media assets. All systems are web-based and use the same underlying object-oriented technology. The paper provides a brief case study that describes the main features of the three pieces of software as an example of the need for a variety of approaches in the support of cooperative work and design. The paper concludes by advocating an object-oriented, domain-specific approach to creating computer-supported cooperative systems based on the analysis of the task at hand.

title	A different approach to planning and design - Combining a planning theory in architectual design with elearning.
doi	https://doi.org/10.52842/conf.ecaade.2003.161
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 161-164
summary	We have developed a rather uncommon way of understanding and teaching architectual design and the use of computers in this process: Our idea consists in defining the design process not only as finding a nice shape for an object like a building or a new car. We see designing and planning as the ""art"" of solving complex problems. This implies, that the design process is not the mere use of methods or tools to solve a given problem, but the process of understanding the roots of the problem and finding a suitable and often alternative and unusual solution. The way we teach this process is enhanced by the use of computers and webbased applications. In this paper we will describe the key elements of the planning and design theory used as well as the methods for teaching these ideas to graduate students. Lastly, we point out the experience that came from the practical implementation.

title	A NEW APPROACH TO THE INTERACTIVE RESOLUTION OF CONFIGURATION PROBLEMS IN VIRTUAL ENVIRONMENTS
source	3rd International Symposium on Smart Graphics, Heidelberg, Germany, 2-4, July 2003. http://www.smartgraphics.org/ . Proceedings published by Springer: Lectures notes in Artificial Intelligence.
summary	Intelligent Virtual Environments integrate AI techniques with 3D real-time environments. As such, they can support interactive problem solving, provided the underlying AI techniques can produce solutions within a time frame matching that of user interaction. In this paper, we describe an intelligent virtual environment based on Constraint Logic Programming (CLP), integrated in a real-time 3D graphic environment. We have developed an event-based ap-proach through which user interaction can be converted in real-time into appro-priate solver queries which are then translated back into automatic reconfigura-tions of the Virtual Environment (VE). Additionally, this framework supports the interactive exploration of the solution space in which alternative solutions (configurations) can be found. We demonstrate the system behaviour on a con-figuration example. This example illustrates how solutions can be interactively refined by the user through direct manipulation of objects in the VE and how the interactive search of alternative solutions in the VE is supported by these type of systems.

title	The Prototype of Digital Cities On Line A Cognition-Oriented Approach for Spatially Metaphorical Model
doi	https://doi.org/10.52842/conf.caadria.2003.651
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. 651-662
summary	The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. However, human how to entry into the new emerging digital cities, to percept themselves in around cities, and then taking shape the recognition of digital city forms? How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of spatial cognition, to find the explicitly spatial structures and relations in digital city upon physical city. This paper studied by the viewpoint of cognition in order to propose a prototype of metaphor of digital city.

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	Possibilities of applying the E-government management concept in Serbian cities
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Recent urban transformations worldwide consequentially lead to the numerous environmental problems that have to be solved bycomplex structure of social interest groups which have to be included in that process. This demands initiated requisitioning andmodification of concepts and methodologies of planning and managing urban development. At this moment there are differentmodels used in world wide practice, but main bases of new methods and techniques are the same. Leaving the idea of possibility ofconstituting the universal urban planning model lead to very productive results in developing the disciplinary methodologies. Processof transformation of traditional comprehensive urban planning model to integrated procedural pluralistic model (based on sustainabledevelopment principles) is something that can be underlined as a main characteristic of disciplinary development. The questions ofdecision making mechanisms and plans implementation are put in axes of conceptual and methodological considerations. Urbanplanning loses the classic form of making the multi level comprehensive urban plans with exact spatial and time horizon. It means, ingeneral that planning and managing of urban development is aiming to be realistic, decentralized, strategic and problem oriented,arbitrary, not instructive, but understood as a efficient and effective process.Operational support to the this kind of approach are Decision Support IT tools, such as GIS - Geographical Information Systems orES -Expert Systems. Usability of IT tools is based on their capability to perform fast and complicated processing of spatial data andon their flexibility towards specific real problems which are to be solved. In order to use maximum of capabilities of these tools inpractice problem solving it is necessary to adjust their structure and usage to the: - actual conditions of socioeconomic of the contextin which urban development planning and management is performed, - practical demands that managing of urban development has tofore fill, - all participants in urban management process, - institutional mechanisms and procedures.

title	ArDOT: A tool to optimise environmental design of buildings
source	Building Simulation 2003 (Eighth IBPSA Conference). Eindhoven, Netherlands
summary	Environmental design of buildings involves ‘finding the optimum’ solution satisfying predefined objective(s) (e.g., reduction in operating/capital cost, maximisation of daylighting etc.). A number of computer based simulation models exist to assist professionals in finding this optimum through building performance assessment. Contemporary practices involving building simulation require enormous effort to prepare input, extract output, and visualize data, which restricts designers from realizing the full potentials offered. In most cases, rules of thumb are applied and experienced guesses are made; simulation software is used only to validate the assumptions, which do not necessarily lead to the intended optimum. Moreover, these tools have been developed as simulation engines, which is inadequate to visualize the compounded and interdependent effect of a large number of design variables. The authors believe that to realize the potential offered by building simulation software, a new breed of DBSs (Decision Based Systems) is needed coupling existing simulation engines with formal optimisation methods through neutral data standards (BPM – building product models) for seamless integration. This paper first elaborates on the previous attempts at solving integration issues related to the design process and simulation; also attempts at finding the limitations. Secondly, formulation of design problems as optimisation has been discussed with reference to the different stages of design. Thirdly, for effective integration of activities among stakeholders and processes, the use of client/ server oriented building product model has been proposed to overcome the limitations of file-based prototypes. Analysis and discussions based on the above aspects form as justification for ArDOT, an Architectural Design Optimisation Tool under development at IRUSE, National University of Ireland, Cork. Combining all three aspects into one makes ArDOT unique, which is essentially an enhanced decision making tool for the design of energy efficient buildings.

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	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	This research presents the collaboration in the VDS system through a microcomputer technology- a PDA (Personal Digital Assistants). Architect can collaborate anytime anyplace via VDS, a substitution to an old system that requires a specific location to work on. This research has studied and analyzed the format and the limitation of collaboration between PDA and Personal Computer, the wireless communication technology, and the Web Service technology, which enable different devices to share information through the Internet Network. The work process and the studied information have been used to develop a Web Application, a collaboration tool for a team of architect and designer. This Web Application has been tested in a renovation project, a clubhouse for a scuba diving place The objective of this research is to become a guideline of collaboration in architectural design work through Smart Object in order to serve the coming Ubiquitous era (Weiser, 1998)

title	A NEW APPROACH TO VIRTUAL DESIGN FOR SPATIAL CONFIGURATION PROBLEMS,
source	7th IEEE International Information Visualisation Conference, London, UK, 16-17 July 2003. http://www.graphicslink.demon.co.uk/IV03/
summary	In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of Intelligent Virtual Environment, we propose an intelligent configuration system based on constraint logic programming (CLP), integrated in a real-time 3D graphic environment. This type of integration facilitates the expression of design knowledge in the VE and enables the user to interactively solve and/or refine a spatial configuration problem. In the system described in this paper, the user can visually explore configurations, but his interaction with objects of the configuration problem triggers new cycles of constraint propagation from the modified configuration to produce a new compatible solution.

summary	The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

summary	Collaborative design has become a research paradigm in design studies. To make effective collaborative design, an information service mechanism for helping collaborators to access related information of specific design situation is getting important. This paper presents an approach of applying data mining techniques to reveal information patterns for managing collaborative design information. A visual interface of linking design information based on revealed patterns are presented and issues are discussed.

title	Object oriented Thinking for Technical Architecture Modelling

summary	Today it is increasingly important to focus the efforts of research on thinking about the great innovation introduced by digital 3D modelling in the housing sector, not only in the merits but also in the methods of the designing conception. Thinking of an object-orientated constructive 3D model does not only mean to represent it, but to conceive it, by generating it within an existing although virtual space. This encourages one to focus not only on the formal and compositive side, but also on the technical and technological side of the future building, whose constructive components are brought in, arranged and above all connected within the virtual building, as will happen in the practice of building, according to the building rules.

title	SpaceScope: Spatial Content-Based Retrieval of Architectural Floor Plans
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. 53-62
summary	This research investigates spatial information retrieval in architecture, based on an efficient metadata that is crucial for content-based retrieval. SpaceCore is the metadata schema for spatial information on a floor plan implemented with RDF (Resource Description Framework). To generate metadata, we analyse the factors of spatial information, and then construct a data model containing the content and structure of spatial information. To exploit the metadata, we suggest various query operations with possible predicates and interfaces. SpaceScope, the spatial information retrieval system, consists of three modules: an input data module, a query module, and a browse module. As to implementation, we have already developed the real time plan-structuring system, called “Vitruvius”, as an inputting and modelling data module (using C++). Based on the database, the system performs the similarity analysis and then evaluates the alternative plans with the retrieval goals. At the end of the paper we discuss the potential of SpaceScope in the schematic design stage of the architectural design process, possibly improving and triggering the designer’s conceptual approach against a logical background and facilitate rapid decision-making after full consideration.

title	CAD Smart Objects: Potentials and Limitations
doi	https://doi.org/10.52842/conf.ecaade.2003.547

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.
