title	An overview of virtual city modelling: emerging organisational issues
source	CUPUM07 10th International Conference on Computers in Urban Planning and Urban Management, Iguassu Falls, Brazil, 11-13 July 2007
summary	This paper presents a recent overview of the increasing use of Virtual Reality (VR) technologies for the simulation of urban environments. It builds on previous research conducted on the identification of three-dimensional (3D) city models and offers an analysis of the development, utilization and construction of VR city models. Issues pertaining to advantages, barriers and ownership are identified. The paper describes a case study of the development of a VR model for the city of Newcastle upon Tyne in the UK and outlines the role that academic institutions can play in both the creation and utilization of urban models. The study offers a new approach for the creation, management and update of urban models and reflects on issues which are emerging. Areas for future research are discussed.

title	Parametric Form Finding in Contemporary Architecture
source	Vienna University of Technology; Building Science & Technology
summary	The search of new geometry has been during the last years an interesting subject for Contemporary Architecture. As the 21st century brought a new era for architectural design, CAD programs have evolved together with the idea of Form Finding. The possibilities offered make the collaboration of the architect with the computer now possible in terms of searching the appropriate form for given cases. As the analysis of contemporary architectural pieces has indicated, the procedure of architectural design can be semi-automated. Parametric Form Finding is transferring generative approaches into the architectural design workflow by introducing a set of rules to describe the constrains of the form. Given this context, two methods have been realized, which are guided by the user by providing basic two dimensional shapes, restrictions and form characteristics. The approach is fitted in a plug-in for the modeling environment of Rhinoceros that generates three dimensional form based on the user?s input. The methods followed are being evaluated.

title	Heuristic Methods in Architectural Design Optimization
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 507-514

summary	This paper focuses on optimization methods and their role in the “digital chain” in architectural design and production. These methods were developed in the research phase of the project ‘New Monte Rosa Shelter’ to improve cost efficiency and to adapt the design for the specific environmental and constructive constraints of the site. The New Monte Rosa Shelter is a project designed by students for a mountain shelter at high altitude. For transportation and construction reasons, optimization was required to minimize costs, material, and weight of the structure. For this project a series of programs using genetic algorithms were written to optimize the geometry of the wooden framework. These programs were combined to create a digital toolset, giving the architects direct output of surface information from the framing data, and allowing for output as a three-dimensional model. This optimization toolset gives creative control back to the architects themselves, who can now transform and manipulate the architecture. This paper describes the overall process, and outlines one specific optimization tool, a program that enables architects to “fill” the wooden framework automatically with different material and construction systems and understand the cost and efficiency implications based upon the structural analysis software and the programmed heuristic methods.

title	Foam Structures: A Comparative Structural Efficiency Analysis Based on the Building Case "Watercube"
source	Vienna University of Technology; Building Science & Technology
summary	Foam structure in macro-scale has arisen as a new type of large span building structure recently which is a product of cooperation of advanced structural design, radical architectural design approach, and computer and software technology, and efficiency of foam structure became an important question to answer which could help further structural improvements. This study analyses efficiency of large span foam structure relative to conventional large span building structures with a parametric simulation method. Space frames are a special case of conventional large span structures one compared with foam structures, because it satisfies criteria such as being lightweight and three-dimensional as foam structure. Analysis is based on the comparison of base cases of foam model and space frame model, which are developed on light of real projects the Water Cube and the Symbol Zone of Expo’70, based on the parameters structural depth, weight and displacement, and vertical and horizontal load cases. During the analysis structural behavior of base cases were simulated by using a special structural behavior simulation program. It was found that foam model is more efficient than space frame model in terms of structural depth which is an important issue for large span building structures from both architectural and engineering point of view. Capability of spanning large distance with significantly less structural depth makes foam structure a preferable, new generation, steel structure for large spans. Moreover, the development process of base case foam model demonstrated the critical importance of geometrical design concerns of foam structure. Structural behavior simulations were exposed that structural optimization is one of the vitally important process of structural design of the foam structure.

title	Digital Design Pedagogy: Strategies and Results of Some Successful Experiments
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 192-203

summary	Are there design techniques unique to digital design software that should be explicitly taught or should one leave it to serendipity for students to discover these techniques? A review is provided of the experience of different teaching strategies for digital design pedagogy over a four-year period and, on the basis of this experience, recommendations for successful strategies are given. The teaching strategies presented assume prior training in basic three-dimensional digital modeling and hence represent a first exposure to digital design methodology. The three areas in which digital design provides unique strengths are: a) a three-dimensional design process; b) curvilinear and geometric design; and c) simulation to test the effectiveness of a design from various points of view, with particular emphasis on natural lighting. A brief overview is provided of the theoretical content of the course, the nature of the in-class design exercises, and the term project; all are visually illustrated with examples. The endeavour to reach an optimal pedagogical strategy was both enriched and complicated by the constant change in functional ability of digital design and simulation software and the availability of new software. Nevertheless, it was possible to draw some useful conclusions.

title	Re-Placing Embodied Interaction: Palestinian Architects Virtual Community
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 381-398
summary	Our ongoing project Palestine Architects Platform (PAP) –and PAP VE is a project intended to re-bond Palestinian architects and facilitate communication between them in Virtual Environments “virtual land” using virtual means. We used it as an example to argue that its inherently embedded spatial metaphor could compensate for the physical disconnectedness, and allow interaction on many different levels. Our paper proposes an interactive archiving and networking location where discourse is not only stored but categorised, analysed, retrieved and used to start new topics, or can be used to improve new debates. The focus is on the social values of PAP network and its empowering nature. The design and the structure is not simply a system for online socialisation rather it is a result of thoroughly studying available networks and their principles. It is a result of deep analysis of reality behind this community. We finally propose a set of principles that can secure a real innovative and creative knowledge exchange.

summary	In the era of communication, the participation in internet-communities has grown to become a motor for innovation in software and community platforms. The paper describes the hypothesis that, by creating a virtual city (or a second city) a new type of social, economic and scientific network is established, which is supported through visual communication technologies. The various users bring, per se, their own intrinsic motivation and requirements to the system. Nonetheless, a personal identification with a city/neighbourhood/house/apartment can be used to awake awareness and to foster participation. This is especially important when dealing with the city inhabitants. City modelling itself has been carried out for over a decade. Projects such as the city model of Graz have shown how city models can be established so as to be scalable for new information (Dokonal et al 2000). Furthermore, these city models have been used in the education of future architects and urban planners. The project described here moves in the opposite direction: the model moves out of the classroom to an interdisciplinary city-model-platform. The work described here is the conceptual model for a multi-dimensional data set that models the city. This has spawned a host of other projects using the model as a foundation for further interactivity development and the extension of the model itself. The paper describes the structure of the conceptual model and the first experience of incorporating diverse projects such those mentioned above. The model also is structured so as to be compatible with the XML standards being developed for city information (CityGML). The goal of the project is to create a data set describing the city that not only describes the geometry, but also the history (including planned histories) and nature of the city. In contrast to virtual realities, which attempt to create a separate world (e.g. Second Life), the Second City is intended as an interdisciplinary repository for the geometrical, historical and cultural information of the city.

title	Collaborative Cooling Load Analysis Software for Public Participation on Energy Conservation
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.o0s
summary	This article is part of a research on developing cooling load analysis software for energy conservation. This research focuses on developing the system of Collaborative Design and Public Participation System which allows property owners, architects, engineers as well as others outside the field, to contribute to design process based on the concept of energy conservation within the collaborative virtual environment. The combination of the two ideas between collaborative virtual environment and Analysis Engine of cooling load calculation changes the traditional working processes in which architects and engineers work separately. From the traditional process where both architects and engineer redevelop the whole project from the beginning when redesigning is in need, this new collaborative process requires less time and energy from both parties due to the simultaneous participation of architects, engineers as well as other contributors. In this research, Microsoft© Direct3D® - API based Virtools® is used to develop Real-Time Simulation and its internal script in the calculation process. Through the implementation process, the study aims to develop the 3 components of 1) urban area database illustrating simulating maps for users 2) Graphic User Interface (GUI) connected to other software modules for further expansion and 3) Virtual Network Environment allowing multiple users to log in and use the programme at the same period of time.

title	Digital Fabric: Generating Ceramic Catenary Networks
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 48-55
doi	https://doi.org/10.52842/conf.acadia.2007.048
summary	Digital modeling in the design environment has prompted intuitive shaping of architectural form. The pliability of the imagination allows limitless possibilities of shape without a constrained methodology. This paper chronicles a design exploring catenary form-finding using parametric constraints in a dynamic modeling environment. Catenary structural networks are treated as digital cloth objects. Applying parametric edge and point constraints simulates various behavior patterns under gravity load. The integration of real-time Finite Element Method [FEM] and dynamic cloth simulation presents an intuitive method for the design and analysis of catenary structures. Constraints resist the limitless pliability of shape and hone the intuition using force to find form realized as a ceramic catenary network.

title	SecondLife: A Computer-Mediated Tool for Distance-Learning in Architecture Education?
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 17-34
summary	Despite the importance of distance learning for its ability to reach a wide audience, easiness to access materials, and its lower cost compared to traditional learning, architecture education has not been well served by distance education. This is because it has a higher level of learning objectives, it is taught by coaching methodologies, and involves nonverbal forms of communication. One of the most common learning methods used in the design studio is the Criticism/Critique, which is a graphic and oral type of communication between the tutor and the students. In this investigation, Second Life, a massive multi-user online virtual environment that offers three-dimensional spatial capabilities via Avatars impersonation, is used as a computer-mediated tool for text and graphic-based communication in a distance learning situation. The study describes a demonstration experiment where students had to communicate with their tutor, display and describe their projects at a distance, in a purposely designed criticism space in SecondLife. The main objective of this paper is to observe and document the effects and the use of SecondLife virtual environment as an online 3D graphical-based tool of computer-mediated communication in distance learning in architecture education. The study also answers some questions: How well did the students use the tools of the medium provide? Was there a sense of personal communication and realism gained through using Avatars in the virtual environment? Did SecondLife provide a successful means of communication for a graphic-based context? And what are the students’ opinions about the learning environment? Using multiple methods of data collection, mainly based on an electronic observation of the experiment, questioning the participants before and after the experiment, and the analysis of the chat transcripts, the study presents descriptive results of the experiment, and discusses its main features. Proposals for modifications are made for future replications.

title	Three dimensional isovist analysis method [Método de Análisis Tridimensional con isovistas]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 174-176
summary	This paper presents a three dimensional method of isovist analysis implemented in the MaxScript programming language. The script accepts as its input a standard three dimensional model of the buildings and terrain being analyzed, upon which a N×N grid is projected. Each square of this grid is assigned a height value, thereby producing a simplified surface description which is amenable to mathematical analysis. A three dimensional isovist is then generated for each grid square, by placing an observation point 1.5 meters above its center and finding the intersection of a series of rays from this point to the input model. The distance from the observation point to the intersection is summed over for all the angles studied giving a compound isovist measurement for the grid square under consideration.

title	Emergent Form from Structural Optimisation of the Voronoi Polyhedra Structure
source	Proceedings of the Generative Arts conference, Milan, 2007
summary	In the course of the exploration of computational means in the architectural design process, in order to investigate more complex, adaptive geometries, the Voronoi diagram has recently gained some attention, being a three-dimensional space-filling structure which is modular but not repetitive. The project looks at the Voronoi diagram as a load-bearing structure, and whether it can be useful for structural optimisation. Hereby the edges of the Voronoi polyhedra are regarded as structural members of a statical system, which then is assessed by structural analysis software. Results seem to indicate that the Voronoi approach produces a very specific structural as well as spatial type of order. Through the dislocation of the Voronoi cells, the statical structure becomes more complex through emergent topology changes, and the initially simple spatial system becomes much more complex thorough emerging adjacencies and interconnections between spaces. The characteristics of the emerging form, however, lie rather in the complexity how shifted spaces and parts are fitted together, than in a radical overall emergent geometry. Spatially as well as a structurally, the form moves from a simple modular repetitive system towards a more complex adaptive one, with interconnected parts which cannot stand alone but rather form an organic whole.

title	The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary	At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

title	An Empirical Investigation into the Influence of Media Types on Design Cognition and Methodologies
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.x4b
summary	This paper reports on the findings of an empirical investigation into the impact of different media on design methodology. The statistical sample included 49 fourth year architecture students, divided into three groups: the drawing group, the physical model group and the computer group. They were given a problem of designing a façade in an urban context in Glasgow over a two week period. The design process of each group was monitored over that period through observations, recordings and attitude measurement via a questionnaire survey. The results were analysed using the Statistical Programme for Social Sciences (SPSS). The dendrograms from cluster analysis revealed that there were well established perceptual dimensions, or clusters, for the façade’s design variables within the three groups because of using different media. The impact of media on design creativity, both as a process and a product, was investigated. All three media types yielded a positive correlation between ‘media made design decisions more creative’ and ‘media made design scheme more creative’- with a correlation coefficient of 0.708 which was significant at the 0.01 level, p<0.05.

title	Modeling and Simulating the City: Deciphering the Code of a Game of Strategy
source	International Journal of Architectural Computing vol. 5 - no. 3, pp. 571-586
summary	This research includes a new teaching proposal for architecture and geography, based on Systems Theory and Dynamics Systems, aimed at improving the understanding of the complex structure and dynamics of the city. SimCity, a game of strategy that allows us to design and to plan the city, is used as the software, with the aim of conducting didactic experiments, and integrating the complex relations that configure the city. The methodology incorporated theoretical and experimental stages, and concluded with a simulation exercise. The exercise had a very good reception, as a method for learning and research, creating a great aptitude for generating good research questions, by making many variables visible simultaneously. The research has developed, and participants have, subsequently, been exposed to the second version of the course, where new concepts are being integrated (emergence and cellular automata) to deepen the theoretical base, and to allow further analysis and experimentation with the game.

title	Crossing the Cultural Divide: A Contemporary Holistic Framework for Conceptualising Design Studio Education
source	CONNECTED 2010 – 2ND INTERNATIONAL CONFERENCE ON DESIGN EDUCATION 28 JUNE - 1 JULY 2010, UNIVERSITY OF NEW SOUTH WALES, SYDNEY, AUSTRALIA
summary	While the studio is widely accepted as the learning environment where architecture students most effectively learn how to design (Mahgoub, 2007:195), there are surprisingly few studies that attempt to identify in a qualitative way the interrelated factors that contribute to and support design studio learning (Bose, 2007:131). Such a situation seems problematic given the changes and challenges facing education including design education. Overall, there is growing support for re-examining (perhaps redefining) the design studio particularly in response to the impact of new technologies but as this paper argues this should not occur independently of the other elements and qualities comprising the design studio. In this respect, this paper describes a framework developed for a doctoral project concerned with capturing and more holistically understanding the complexity and potential of the design studio to operate within an increasingly and largely unpredictable global context. Integral to this is a comparative analysis of selected cases underpinned by grounded theory methodology of the traditional design studio and the virtual design studio informed by emerging pedagogical theory and the experiences of those most intimately involved – students and lecturers. In addition to providing a conceptual model for future research, the framework is of value to educators currently interested in developing as well as evaluating learning environments for design.

title	Developing a New Approach of Computer Use ‘KISS Modeling’ for Design-Ideas Alternatives of Form Massing: A framework for three-Dimensional Shape Recognition in Initial Design Phases
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 745-756
summary	This research aims at developing a new approach called ‘KISS Modeling’. KISS is generally a rule of ‘Keep It Simple, Stupid’ that will be applied in modeling process investigated and presented by the research. The new approach is implemented in a computer program ‘KISS Modeling’ that generates three dimensional forms based on simplifying the concept of shape recognition in design. The research, however, does not employ totally concepts of shape recognition or shape understanding in Artificial Intelligence and psychology. The research, in summary, investigates and describes: 1) a new approach of computer use contributing to generating design-ideas alternatives of form massing in initial design phases, within a simple way that any designer can understand at single glance, 2) implementation of shape recognition for generative three dimensional forms, 3) function to generate different outputs from different recognition, and 4) case studies introduced through applications and functions of the three dimensional modeling system presented by the research. The research concluded that the introduced processes help the user improve the management of conceptual designing through facilitating a discourse of his/her modeling of design-ideas massing.

title	Visual-Physical Grammars
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

summary	The aim of this research project is to develop a methodological process that allows the designer to assemble and create various scenarios representing an urban environment through the utilization of economical computer based methods. During the last decade different techniques have been developed to address the needs of visualisation of urban areas many being based on photographic and photogrammetric systems. The demand for 3-D urban models continues to grow and although new technologies have undoubtedly reduced the time needed for the construction of a 3D model, there are still some remaining problems related to data quality and the level of the dimensional accuracy. On the basis that these problems are primarily related to software and hardware constraints and in conjunction with the fact that the richness and complexity of an urban space is difficult to represent in a 3D context, there is a growing interest in the modelling of the urban fabric which is not dependant on heavily capitalised technology for its data. The core principle of the current research project is summarised in the process of deploying a mechanism, which will allow the visualisation of urban form without loosing its quality and architectural characterisation. This technique suggests that a selection of various building types can be collected and described by their architectural elements, textures, scale and dimensions. From each group of buildings a library of fragmented architectural components can be then derived. The accomplishment of this methodology is the formulation of a 'grammar' comprised of a characteristic ‘syntax’ and its associated ‘vocabulary’. Therefore the expected outcome of this research is an approach that would allow the designer to create easily and quickly not only any desired building but additionally any imaginary cityscape.

summary	This communication is based on the development of a new subject to be imparted in collaboration with three Departments (Visual Communication, Projects and Construction) at the School of Architecture of Barcelona. It is a work that has been financed with a special grant from our university, aimed at the development of new teaching modalities and, in particular, of those that would develop the use of new technologies, collaboration among university departments and eLearning. The aim of the communication is twofold. First, to present some results that we consider valuable in themselves, as much for the techniques as for the methodology that we have used. Second, to propitiate a debate on the new situation that the teaching of architecture is moving to, due to the advance of a series of instruction methods where the methodological organization, the storing of informative material and the preparation of autonomous interactive systems, open more and more effective roads of learning but that, at the same time, point towards a new educational structure that fits badly within the traditional structures in which we have still to work daily. Regarding the first point, the main aspects to highlight are: a) the development of a selflearning system by means of a very complete series of tutorials that allow a gradual acquisition, depending on the necessities or interests of each student, of geometric modeling, parametric design, visual simulation and interactive animation techniques, b) the development of a system of general information supply and on line comments and corrections. Regarding the second point, a provisional theoretical framework has been elaborated based on the consideration of the ubiquitous visual communication media as misleading mediators of a personal relationship. This theoretical frame has been tested by a few experiences carried out with the collaboration of students implied in the project. The general conclusion is that both challenges must be faced at the same time: new educational technologies must be analysed and integrated in our curricula and a new theoretical framework, able to clarify the difference between instruction and education, must be developed in parallel with those technologies.
