title	Generic representations : an approach for modelling procedural and declarative knowledge of building types in architectural design
source	Eindhoven University of Technology
summary	The building type is a knowledge structure that is recognised as an important element in the architectural design process. For an architect, the type provides information about norms, layout, appearance, etc. of the kind of building that is being designed. Questions that seem unresolved about (computational) approaches to building types are the relationship between the many kinds of instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called ‘prototypes’) face problems clarifying these questions. The research work at hand proposes to investigate the role of knowledge associated with building types in the design process.Knowledge of the building type must be represented during the design process. Therefore, it is necessary to find a representation which supports design decisions, supports the changes and transformations of the design during the design process, encompasses knowledge of the design task, and which relates to the way architects design. It is proposed in the research work that graphic representations can be used as a medium to encode knowledge of the building type. This is possible if they consistently encode the things they represent; if their knowledge content can be derived, and if they are versatile enough to support a design process of a building belonging to a type.A graphic representation consists of graphic entities such as vertices, lines, planes, shapes, symbols, etc. Establishing a graphic representation implies making design decisions with respect to these entities. Therefore it is necessary to identify the elements of the graphic representation that play a role in decision making. An approach based on the concept of ‘graphic units’ is developed. A graphic unit is a particular set of graphic entities that has some constant meaning. Examples are: zone, circulation scheme, axial system, and contour. Each graphic unit implies a particular kind of design decision (e.g. functional areas, system of circulation, spatial organisation, and layout of the building). By differentiating between appearance and meaning, it is possible to define the graphic unit relatively shape-independent.If a number of graphic representations have the same graphic units, they deal with the same kind of design decisions. Graphic representations that have such a specifically defined knowledge content are called ‘generic representations.’ An analysis of over 220 graphic representations in the literature on architecture results in 24 graphic units and 50 generic representations. For each generic representation the design decisions are identified. These decisions are informed by the nature of the design task at hand. If the design task is a building belonging to a building type, then knowledge of the building type is required. In a single generic representation knowledge of norms, rules, and principles associated with the building type are used. Therefore, a single generic representation encodes declarative knowledge of the building type. A sequence of generic representations encodes a series of design decisions which are informed by the design task. If the design task is a building type, then procedural knowledge of the building type is used.By means of the graphic unit and generic representation, it is possible to identify a number of relations that determine sequences of generic representations. These relations are: additional graphic units, themes of generic representations, and successive graphic units. Additional graphic units defines subsequent generic representations by adding a new graphic unit. Themes of generic representations defines groups of generic representations that deal with the same kind of design decisions. Successive graphic units defines preconditions for subsequent or previous generic representations. On the basis of themes it is possible to define six general sequences of generic representations. On the basis of additional and successive graphic units it is possible to define sequences of generic representations in themes. On the basis of these sequences, one particular sequence of 23 generic representations is defined.The particular sequence of generic representations structures the decision process of a building type. In order to test this assertion, the particular sequence is applied to the office building type. For each generic representation, it is possible to establish a graphic representation that follows the definition of the graphic units and to apply the required statements from the office building knowledge base. The application results in a sequence of graphic representations that particularises an office building design.Implementation of seven generic representations in a computer aided design system demonstrates the use of generic representations for design support. The set is large enough to provide additional weight to the conclusion that generic representations map declarative and procedural knowledge of the building type.

title	An electronic design assistance tool for case-based representation of designs
source	Automation in Construction 6 (4) (1997) pp. 265-274
summary	In precedent based design, solutions to problems are developed by drawing from an understanding of landmark designs. Many of the key design operations in this mode are similar to the functionalities present in case-based reasoning systems: case matching, case adapting, and case representation. It is clear that a rich case-base, encoding all major product types in a design domain would be the centerpiece of such an approach. EDAT (Electronic Design Assistance Tool) is intended to assist in precedent based design in the studio with the potential of expansion into the office setting. EDAT has been designed using object oriented system development methods. EDAT was used in a design studio at Carnegie Mellon University, during Spring 1996.

doi	https://doi.org/10.52842/conf.acadia.1999
summary	Throughout known architectural history, representation, media and design have been recognized to have a close relationship. This relationship is inseparable; representation being a means for engaging in design thinking and making and this activity requiring media. Interpretations as to what exactly this relationship is or means have been subject to debate, disagreement and change along the ages. Whereas much has been said about the interactions between representation and design, little has been elaborated on the relationship between media and design. Perhaps, it is not until now, surrounded by all kinds of media at the turn of the millennium, as Johnson argues (1997), that we have enough context to be able to see and address the relationship between media and human activities with some degree of perspective.

title	Repairing CAD models
source	Proceedings of IEEE Visualizationí97, pp. 363-370
summary	We describe an algorithm for repairing polyhedral CAD models that have errors in their B-REP. Errors like cracks, degeneracies, duplication, holes and overlaps are usually introduced in solid models due to imprecise arithmetic, model transformations, designer's fault, programming bugs, etc. Such errors often hamper further processing like finite element analysis, radiosity computation and rapid prototyping. Our fault-repair algorithm converts an unordered collection of polygons to a shared-vertex representation to help eliminate errors. This is done by choosing, for each polygon edge, the most appropriate edge to unify it with. The two edges are then geometrically merged into one, by moving vertices. At the end of this process, each polygon edge is either coincident with another or is a boundary edge for a polygonal hole or a dangling wall and may be appropriately repaired. Finally, in order to allow user- inspection of the automatic corrections, we produce a visualization of the repair and let the user mark the corrections that conflict with the original design intent. A second iteration of the correction algorithm then produces a repair that is commensurate with the intent. Thus, by involving the users in a feedback loop, we are able to refine the correction to their satisfaction.

title	Hierarchical Decomposition of Architectural Computer Models
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 197-203

summary	Architectural models can be represented in a hierarchy of complexity. Higher level or more complex architecture structures are then designed by repetitively instantiating libraries of building blocks. The advantages are that the object can be achieved in modular fashion and any modification to the definition of a building block can be easily propagated to all higher level objects using the block. Unfortunately, many existing representations of architectural models are monolithic instead of hierarchical and modular, thus, making the reuse of models very difficult and inefficient. This paper describes a research project on developing a tool to decompose a monolithic architectural model into elementary building blocks and then create a hierarchy in the model representation. The tool provides a graphical interface for the visualization of a model and a cutting plane. An associated algorithm will then automatically detach parts of the model into building blocks depending on where the user is applying the cutting plane. Studies will also be made on dividing more complex models employing spherical and NURBS surfaces.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 885-915
summary	Genetic algorithms are used to evolve rule systems for a generative process, in one case a shape grammar,which uses the "Dawkins Biomorph" paradigm of user driven choices to perform artificial selection, in the other a CA/Lindenmeyer system using the Hausdorff dimension of the resultant configuration to drive natural selection. (1) Using Genetic Programming in an interactive 3D shape grammar. A report of a generative system combining genetic programming (GP) and 3D shape grammars. The reasoning that backs up the basis for this work depends on the interpretation of design as search In this system, a 3D form is a computer program made up of functions (transformations) & terminals (building blocks). Each program evaluates into a structure. Hence, in this instance a program is synonymous with form. Building blocks of form are platonic solids (box, cylinder, etc.). A Variety of combinations of the simple affine transformations of translation, scaling, rotation together with Boolean operations of union, subtraction and intersection performed on the building blocks generate different configurations of 3D forms. Using to the methodology of genetic programming, an initial population of such programs are randomly generated,subjected to a test for fitness (the eyeball test). Individual programs that have passed the test are selected to be parents for reproducing the next generation of programs via the process of recombination. (2) Using a GA to evolve rule sets to achieve a goal configuration. The aim of these experiments was to build a framework in which a structure's form could be defined by a set of instructions encoded into its genetic make-up. This was achieved by combining a generative rule system commonly used to model biological growth with a genetic algorithm simulating the evolutionary process of selection to evolve an adaptive rule system capable of replicating any preselected 3D shape. The generative modelling technique used is a string rewriting Lindenmayer system the genes of the emergent structures are the production rules of the L-system, and the spatial representation of the structures uses the geometry of iso-spatial dense-packed spheres

title	Narrowing the Gap Between CAAD and Computer Programming: A Re-Examination of the Relationship Between Architects as Computer-Based Designers and Software Engineers, Authors of the CAAD Environment
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 491-498
doi	https://doi.org/10.52842/conf.caadria.1997.491
summary	As the interfaces between computer users and computer programs become more friendly, the gap between the architect as designer and the software engineer as strategist increases: the designer is even less inclined to relate to the internal workings of the computer program. One intention of the friendly interface is to allow greater access to relatively sophisticated programs for people to whom the computer is not a natural ally. But with tailor-made software comes the paradox of unintended perspective use. This paper discusses the need for design architects to learn basic programming skills in a contemporary context in order to avoid being inadvertently restricted by a software apparent flexibility. An undergraduate course that sets out to familiarise students with the new possibilities is presented here in detail.

title	Managing Information with Fuzzy Reasoning System in Design Reasoning and Issue-Based Argumentation
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 771-786
summary	Design by argumentation is a natural character of design process with social participation. Issue-Based Information System (IBIS) is an information representation system based on a structured database. It provides a hierarchically linked database structure to manage design information and facilitate design by argumentation. In this paper, we explore the enhancement of IBIS with FRS (Fuzzy Reasoning System) technology. The FRS adds computationally implemented dynamic links to the database of IBIS. Such dynamic links can represent logic relations and reasoning operations among related issues which allows further clarification of relations among issues in IBS. The enhanced system provides a general framework to manage design information and to assist design reasoning, which in turn will contribute to machine assisted design. The final goal is to formulate a system that can represent design knowledge and assist reasoning in design analysis. The system can help designers in clarifying and understanding design related issues, requirements and evaluating potential design alternatives. To demonstrate the system and its potential use, we reexamine a design experiment presented by Schon and represent the design knowledge and reasoning rules of the architects with our system, FRS-IBIS.

summary	The architectural design business is marked by a progressive increase in operators all cooperating towards the realization of building structures and complex infrastructures (Jenckes, 1997). This type of design implies the simultaneous activity of specialists in different fields, often working a considerable distance apart, on increasingly distributed design studies. Collaborative Architectural Design comprises a vast field of studies that embraces also these sectors and problems. To mention but a few: communication among operators in the building and design sector; design process system logic architecture; conceptual structure of the building organism; building component representation; conflict identification and management; sharing of knowledge; and also, user interface; global evaluation of solutions adopted; IT definition of objects; inter-object communication (in the IT sense). The point of view of the research is that of the designers of the architectural artefact (Simon, 1996); its focus consists of the relations among the various design operators and among the latter and the information exchanged: the Building Objects. Its primary research goal is thus the conceptual structure of the building organism for the purpose of managing conflicts and developing possible methods of resolving them.

title	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title	Teaching CAD with Language Learning Methods

doi	https://doi.org/10.52842/conf.acadia.1997.173
summary	By looking at computer aided design as design communication we can use pedagogical methods from the well-developed discipline of language learning. Language learning breaks down a complex field into attainable steps, showing how learning strategies and attitudes can enhance mastery. Balancing the linguistic emphases of organizational analysis, communicative intent and contextual application can address different learning styles. Guiding students in learning approaches from language study will equip them to deal with constantly changing technology. From overall curriculum planning to specific exercises, language study provides a model for building a learner-centered education. Educating students about the learning process, such as the variety of metacognitive, cognitive and social/affective strategies can improve learning. At an introductory level, providing a conceptual framework and enhancing resource-finding, brainstorming and coping abilities can lead to threshold competence. Using kit-of-parts problems helps students to focus on technique and content in successive steps, with mimetic and generative work appealing to different learning styles. Practicing learning strategies on realistic projects hones the ability to connect concepts to actual situations, drawing on resource-usage, task management, and problem management skills. Including collaborative aspects in these projects provides the motivation of a real audience and while linking academic study to practical concerns. Examples from architectural education illustrate how the approach can be implemented.

title	A digital Procedure of Building Construction: A practical project

summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	Visualizing Information: Internet Guidelines for Distributing Architectural Research
source	Virginia Polytechnic Institute and State University
summary	A web site was designed and constructed for the Research + Demonstration Facility (RDF) as a masters thesis project to help educators teach future architects more interactively by using the dynamic medium of the Internet. Students and faculty will learn about evolving architectural research and technology as well as potential consequences of design decisions. Educators will be able to conduct online research, or tele-experiments, in the classroom thus allowing students to learn, in near real-time, the outcome or progress of research on and off campus. This project presents some of the possibilities of how the Internet can enhance re-search information delivery to students and faculty of architecture.

title	A Software for Automatically Verifying Compatibility in Complicated Building Assemblies

summary	The research we are carrying on is intended to develop a tool aiding to design building mechanical assembly systems, which are often characterised by high complexity levels. In fact, when designing complicated building assemblies by making use of common graphical representations, it might be impossible for the operator to choose the proper shape and installation sequence of components so that they do not interfere during the assembly, and to check, in the meantime, the most favorable setting up modalities according to execution problems. Our software, running within CAD, by starting from the definition of the node features, will allow the operator to automatically get three types of representation that can simulate the assembly according to the assigned installation sequence: - instant images of the phases for setting up each component into the node; - 3D views showing the position of each component disassembled from the node and indicating the movements required for connection; - the components moving while the node is being constructed. All the representations can be updated step by step each time modifications to the node are made. Through this digital iterative design process - that takes advantage of various simultaneous and realistic prefigurations - the shape and function compatibility between the elements during the assembling can be verified. Furthermore, the software can quickly check whether any change and integration to the node is efficacious, rising the approximation levels in the design phase. At the moment we have developed the part of the tool that simulates the assembly by moving the components into the nodes according to the installation sequence.

title	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title	Building a Synthetic Cognizer
source	Design Computation Cognition conference 2004, MIT
summary	Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title	Sketch that Scene for Me: Creating Virtual Worlds by Freehand Drawing
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 265-268

summary	With the Web people can now view virtual threedimensional worlds and explore virtual space. Increasingly, novice users are interested in creating 3D Web sites. Virtual Reality Modeling Language gained ISO status in 1997, although it is being supplanted by the compatible Java3D API and alternative 3D Web technologies compete. Viewing VRML scenes is relatively straightforward on most hardware platforms and browsers, but currently there are only two ways to create 3D virtual scenes: One is to code the scene directly using VRML. The other is to use existing CAD and modeling software, and save the world in VRML format or convert to VRML from some other format. Both methods are time consuming, cumbersome, and have steep learning curves. Pen-based user interfaces, on the other hand, are for many an easy and intuitive method for graphics input. Not only are people familiar with the look and feel of paper and pencil, novice users also find it less intimidating to draw what they want, where they want it instead of using a complicated tool palette and pull-down menus. Architects and designers use sketches as a primary tool to generate design ideas and to explore alternatives, and numerous computer-based interfaces have played on the concept of "sketch". However, we restrict the notion of sketch to freehand drawing, which we believe helps people to think, to envision, and to recognize properties of the objects with which they are working. SKETCH employs a pen interface to create three-dimensional models, but it uses a simple language of gestures to control a three-dimensional modeler; it does not attempt to interpret freehand drawings. In contrast, our support of 3D world creation using freehand drawing depend on users’ traditional understanding of a floor plan representation. Igarashi et al. used a pen interface to drive browsing in a 3D world, by projecting the user’s marks on the ground plane in the virtual world. Our Sketch-3D project extends this approach, investigating an interface that allows direct interpretation of the drawing marks (what you draw is what you get) and serves as a rapid prototyping tool for creating 3D virtual scenes.

summary	Since 1997, the Institute for Industrial Building Production (ifib) has been carrying out upper level design studios under the framework of the Netzentwurf or Net-Studio. The Netzentwurf is categorized as a virtual design studio in that the environment for presentation, criticism and communication is web based. This allows lessons learned from research into Computer Supported Cooperative Work (CSCW) to be adapted to the special conditions indigenous to the architectural design studio. Indeed, an aim of the Netzentwurf is the creation and evolution of a design studio planing platform. In the Winter semester 1999-2000, ifib again carried out two Netzentwurf studios. involving approximately 30 students from the Faculty of Architecture, University of Karlsruhe. The projects differed from previous net studios in that both studios encompassed an inter-university character in addition to the established framework of the Netzentwurf. The first project, the re-use of Fort Kleber in Wolfisheim by Strasbourg, was carried out as part of the Virtual Upperrhine University of Architecture (VuuA) involving over 140 students from various disciplines in six institutions from five universities in France, Switzerland and Germany. The second project, entitled "Future, Inc.", involved the design of an office building for a scenario 20 years hence. This project was carried out in parallel with the Technical University Cottbus using the same methodology and program for two separate building sites.
