title	Is it Possible to Design in Full Scale? A CAD Tool in a Synthetic Environment

summary	This project developed a Virtual Architectural Design Tool (VADeT) executed in the C2 Virtual Reality (VR) space. C2 is a synthetic CAVE environment providing a full-scale setting for image projection and perception. Applying this tool for design offers four advantages over other CAD systems. First, it enables navigation performing in full scale to create the sense of immersion and reflection of the seeing-as. Second, it allows the creation, modification, and editing of three-dimensional objects in a virtual space. Third, designs can be modified and viewed simultaneously inside or outside of the generated model to obtain the best design products. Fourth, the entire design process can be recorded and played back. Collectively, this tool serves the purposes of: (1) a three-dimensional sketching tool for manipulating 3-D objects, (2) a design study tool for transparently displaying the design processes, and (3) a design teaching tool to demonstrate the processes by which designers do design. Thus, design in a full-scale representation not only is possible but also is a new and unconventional mode that will heavily influence design thinking.

title	Design coordination modeling: A distributed computer environment for managing design activities
source	College of Architecture, Georgia Institute of Technology
summary	The objective of this thesis is to develop an effective multi-user computer environment supporting design collaboration. This research takes a knowledge-based approach to capture meaningful process semantics specified by designers to effectively realize work. It concentrates on establishing a process infrastructure and tools for managing activities for a building design team, with emphasis on remote collaboration and distributed coordination. The results of this research include a design coordination model (DCM) and the prototype of a future generation of distributed coordination environments. DCM provides a digital representation of design processes and support visibility of coordination logic within a CAD environment. Some extended features of distributed coordination are explored in DCM, equipped with a model server that is developed using a web-based three-tier computing system architecture approach.

title	Networking: media, representation and architecture
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	In this paper we present a pedagogic work, carried out in a third year architecture course, focused on the relationship between teaching content and media. The subject-matter of the course is the concept of representation; an eminently philosophical issue which transcends the limits of a particular discipline. The media that have been used are mostly the web, along with other standard programs to process text and images, create models and animations. The core of this research work is the course ‘Sistemas de Representación’, which has taken place for the first time in the academic year 1999/00. The course is structured in six themes, each one standing for a system of representation: TEXT, FIGURE, OBJECT, IMAGE, SPACE and LIGHT. Within every system, a variety of topics dealing with the concept of representation are addressed in an interdisciplinary manner. A web based learning environment named NETWORKING has been created especially for the course. This environment allows students to perform a variety of collaborative works: drawing visual and linguistic relationships, developing further the works of other students, and participating in collective processes of form generation and space perception.

title	STEP and SGML/XML: what it means, how it works
source	XML Europe ‘99 Conference Proceedings, Graphic Communication Association, 1999, pp. 267-70
summary	The STEP standard, ISO 10303, is the primary standard for data representation and interchange in the product design and manufacturing world. Originally designed to enable the interchange of 3-D CAD models between different systems, like SGML, it has defined and uses a general mechanism for representing and managing complex data of any type. Increasingly products are defined as solid models that are stored in product databases. These databases are not limited to shape but contain a considerable wealth of other information, such as materials, failure modes, task descriptions, product related meta-data such as approvals and much more. The product world is of course also replete with documents, from requirements through specifications to user manuals. These documents both act as input to the product development processes and are output as well. Indeed in some cases documents form part of the product and are given part numbers. It is therefore not surprising to find that there are many companies where there are very real requirements to interact and interoperate between the product data and documents, specifically in the form of SGML-based data. This paper reports on work in progress to bring the two worlds together. This is primarily being done through the SGML and Industrial Data Preliminary Work Item under ISO TC184/SC4. The need for common capabilities for using STEP and SGML together has been obvious for a long time as can be seen from the inclusion of product data and SGML-based data within initiatives such as CALS. However, until recently, this requirement was never satisfied, for various reasons. For the last year or more, a small group has been actively pursuing this area and gaining the necessary understandings across the different standards. It is this work that is reported here. The basic thrust of the work is to answer the questions: Can STEP and SGML be used together and, if so, how?

title	How an Architect Created Design Requirements
source	G. Goldschmidt and W. Porter (eds), Design Thinking Research Symposium: Design Representation, MIT, Cambridge, pp. II.101-124
summary	There is an anecdotal view that designers, during a conceptual design process, not just synthesise solutions that satisfy initially given requirements, but also create by themselves novel design requirements that capture important aspects of the given problem. Further, it is believed that design sketches serve as a thinking tool for designers to do this. Then, what kinds of cognitive interaction with their own sketches enable designers to create novel requirements? The purpose of this paper is to answer this question. We examined the cognitive processes of a practising architect, using a protocol analysis technique. Our examinations focused on whether particular types of cognitive actions account for the creation of novel design requirements. We found that intensive occurrences of a certain type of perceptual actions, acts of establishing new relations or visual features on the sketches, are likely to co-occur with the creation of requirements. This suggests that this type of perceptual actions are the key constituent of acts of creating novel requirements, and therefore one of the important actions in sketching activities. This presents evidence of the view that designing is a situated act, as well as has an implication for design education.

title	Visualisation of Design Using Animation for Virtual Prototyping
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 519-525
doi	https://doi.org/10.52842/conf.ecaade.1999.519
summary	Although recent technology in time-based representation has vastly improved, animation in virtual prototype design field remains the same. Some designers invest a huge amount of money in the latest visualisation and multimedia technology and yet may create even worse animation. They often cramp sequences resulting in many viewers failing to interpret the design positively as they miss a lot of vital information that explains the design. This paper basically reports the importance of film-making understanding for producing good virtual prototype animation. It will be based on a part of a research project on the use of time-based media in architectural practices. It also includes an empirical analysis of several architectural-based documentary films (including an interview with the film director) and past and present computer animation. This paper then concludes with recommendations of good techniques for making animated visualisation relative to the stage at which the animation is produced for better design decision.

title	Virtual Reality in Architectural Education: Defining Possibilities
source	ACADIA Quarterly, vol. 18, no. 4, pp. 7-9
doi	https://doi.org/10.52842/conf.acadia.1999.007
summary	Introduction: virtual reality in architecture Virtual Reality (VR) is an emergent computer technology for full 3D-simulations, which has a natural application in the architectural work, due that activity involves the complete definition of buildings prior to its construction. Although the profession has a long tradition and expertise in the use of 2D-plans for the design of buildings, the increasing complexity of projects and social participation requires better media of representation. However, the technological promise of Virtual Reality involves many sophisticated software and hardware developments. It is based on techniques of 3D-modelling currently incorporated in the majority of drawing software used in architecture, and also there are several tools for rendering, animation and panoramic views, which provide visual realism. But other capabilities like interactivity and sense of immersion are still complex, expensive and under research. These require stereoscopic helmets, 3D pointers and trackers with complicated configurations and uncomfortable use. Most advanced installations of Virtual-Reality like CAVEs involve much hardware, building space and restrictions for users. Nevertheless, diverse developers are working in Virtual-Reality user-friendly techniques and there are many initial experiences of architectural walk-throughs showing advantages in the communication and development of designs. Then we may expect an increasing use of Virtual Reality in architecture.

title	The Architect's Use of the Internet - Study of the Architectural Presentation Possibilities
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 363-368
summary	The Internet media is opening new horizons in communication and representation in architecture. However, its use today is superficial, limited, and without creativity. This study will explore theories, methods and examples of how the virtual space of the Internet can be used in its full potential. That means to present ways of observing, understanding, interacting, and communicating the space without precedents in architecture. The existent presentations made by architects in the Internet are in general poor and static. Through the comparative analysis of two presentations of the same architectural space in the Internet and the use of state of the art technology in the Internet, this study will show innovations that will make the exploration of the architectural space more attractive, dynamic and interactive. The main issues will be on one hand, the improvement in the communication of the design through the use of the Internet, and on the other hand, the rise of the standards in the quality of the architectural presentations. This work will project possible implications of the Internet in architecture.

title	Infographic: Its Incorporation and Relativity in Architectural Design Process
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 313-318
summary	This paper is about an architectural design workshop regularly held at a public university in Santa Fe, Argentina. The class is about 150 students large, with different informatic capabilities and hardware facilities. The design problem of the workshop, which is one year long, is the relationship between architectural project and the construction of the urbanity. This implies both a physical intervention and a cultural expression. Pedagogy seeks students to overcome individualism, characteristic that is hardly induced by PCs, making a socialized design experience. A complementary and simultaneous use of graphic and infographic data is one of the main criteria of the workshop. The idea is to look for students to reach a wide vision by means of the use of different representation systems and means of information. Digital graphic is introduced early in the design process as an electronic model of urban context. It is considered as a one among many other graphic resources and is used together with ordinary models, geometric drawings, aerial and regular photography and hand made sketches. This paper relates the results that have been obtained when students were asked to make an analytic and sensitive approach to the relationship site - urban situation. This relationship has a great importance for the workshop since its goal is to make students to understand the the value of designing in and for the city.

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.

source	Liverpool University
summary	The broad aim of the research is to examine the role of computer generated architectural images on the way different people perceive architecture, and within this field of interest I have established a list of specific tasks to define the specific points of interest to examine. The following list of the main research objectives served as a guide in designing the experimental tests undertaken as part of this research: () Study the effect of both representation techniques and the used media on perceiving architecture. () Establish the differences (if there are any) of perception between different groups of people; principally architects and non-architects, but also subsets of each of these two groups. () To suggest the appropriate technique for presenting architecture for a particular group in a particular stage in the design process. () To investigate the influence of CAAD in architectural education on the students’ perception for architectural images.

title	New Trends In Graphic Representation
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 501-506
summary	In terms of graphic representation, architectural & urban study drawings present some fuzziness related to the multiplicity of scales, to the representation of the urban dynamic and to the means of communicating the contents of these studies for different publics, clearly divided among lay and specialists. Since the 16th century there have been certain stimulating propositions to this theme that have had an enormous, often unacknowleged, impact on the perception and construction of the built environment. Recent experiences in Rio, due to the series of urban projects that are being accomplished, is showing that some architecture offices are adopting new graphic trends in drawings conceived for preliminary studies, diagnoses and inventories. Due to the new possibilities offered by graphic computing they are developing, with diferent softwares, a sort of "patchwork” or "collage” and "sampling” technique for morphological analysis and representantion of places and buildings. This use of graphic computing, as an alternative to the usual realistic depictions that attempts to deal with prosaic simulations of an everyday experience, results in a different type of graphic expression that transcend literalism and appealls to the imagination of the general viewer. It is important to highlight that the analysis of these graphic solutions that attempts to turn visible design problems, could result in the development of new graphic tools that will help the creative design process.

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	Virtual components consisting of form, function and behavior
source	Automation in Construction 8 (3) (1999) pp. 351-367
summary	Software can produce a product model of a building as a consequence of the designers' actions in drawing and evaluating the design. The actions of the designer include interpreting, predicting and assessing the emerging design and describe the building in terms of forms, functions and behaviors. A software prototype has been implemented that incorporates this understanding of the design process in the field of building design. It employs object-oriented classes to represent forms, functions and behaviors. As a software user draws and interprets the design for multiple evaluation issues, the software creates a unique `virtual component' for each entity. During automated reasoning to evaluate the emerging design, virtual components collect and organize form, function and behavior instances to describe the parts of the building. In comparison to other product models, our approach, which we refer to as a `Virtual Product Model', better accommodates change, provides increased support for the design process and enriches the product representation by including function and behavior.

summary	Collaborative Design is a topic of particular current interest. Existing software allows a multiplicity of designers to work on the same project. What the software really allows is accessing to a part of the information of the project and changing it. Sometimes there is a hierarchical distribution of the power of change: some participants can be permitted to operate only on some limited layers of the object representation. In this case the changes they propose are to be accepted by a general manager of the design process. What is lacking in this kind of software is the explicit management on the reciprocal constraints posed by different participants. In this paper, an elementary Collaborative Design System is presented whose main concern is just the management of constraints. Each participant designs the part of the project of his/her concern instantiating objects comprised of geometric description, alphanumeric variables and constraints on both. Constraints can be of two types: absolute or defined by a range of allowed values of the constrained variable. A participant intervening later can accept the constraint, choosing a value in the permitted range, or decide to violate it. In this case the proposed violation is signalled to whom posed it.

summary	It is undeniable that infotechnology has brought significant changes into architectural representation. Whether these changes has altered design conception proccess or are only media matters, is a discussion concerned with the role of graphic expression in architects designs. Is it just a language, or a design thinking tool, fully engaged with the formal solution? Thus, the investigation of the role of represententional systems in the design thinking proccess and the analysis of their intrinsic relationship will approach traditional methods facing the widespread use of Computer Aided Design. There are polemics about the issue: on the one hand, seductive simulations and a plethora of rendering choices available, on the other hand, impersonal expression, to name a few arguments for and against CAD use. Computers have not replaced the straight reciprocity between the acts of conceiving and drawing, between mind and image, which results in manual sketches, quite effective in embodying a design idea. Yet, we have to admit that manipulating complex forms such as Gehry's Guggenheim Museum quickly would not be feasible before CAD advent. We have been faced with new paradigms challenging the graphic expression of architects and urban designers. Besides the consequences of this new reality to design thinking, a crucial point to be stressed at this discussion is the possibility of achieving a balance between the cherished mind-hand intimacy and the available technological resources.

title	The Front of the Stage of Vitruvius' Roman Theatre - A new Approach of Computer Aided Design that Transforms Geometric Operators to Semantic Operators
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 321-333
summary	The driving force of all researches where the systems of computation are used, is the utilization of an intelligent method for the representation of building. The use of computer, in design process, is often limited to technical functions (tekhne), and what one usually calls computer-aided design is often no more than computer-aided drawing. In this research paper we continue a reflection on the architect's work methods, and suggest an approach to design based on the semantic properties of the object (i.e. semantic operators), rather than by geometric operators. We propose a method of computer aid design using procedural models where the initial state of design is vague and undefined. We operate from a paradigm that leads to represent a building by means of parametric functions that, expressed algorithmically, give a procedural model to facilitate the design process. This approach opens new avenues that would permit to add the logos (semantic properties) and lead to a metaphorical representation. By means of procedural models, we show that, from a generic model we can produce a four dimensional model that encapsulate a volumetric model with semantic characteristics. We use a meta-functional language that allows us to model the actions and encapsulate detailed information about various building elements. This descriptive mechanism is extremely powerful. It helps to establish relations between the functions, contributes to a better understanding of the project's aim, and encapsulates the building properties by recalling characteristics of common classes which give rise to a new configuration and a completely original design. The scientific result of this experiment is the understanding and confirmation of the hypothesis that it is possible to encapsulate, by means of computing process, the links between design moves during conceptual and figural decisions and transform the geometric operators in semantic operators.
