title	Models, Scanners, Pencils, and CAD: Interactions Between Manual and Digital Media
source	Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 21-34

summary	This paper discusses new approaches to the relation between handmade and computer aided media in design. The discussion focuses on two advanced studio projects in which graduate student designers incorporated interactions between physical models, a digital scanner, handmade drawings, and the manipulation of images in the computer. These interactions provide a valuable supplement to traditional means -- both manual and digital -- for generating, developing, and representing architectural form. Features of the student’s work that other designers will find significant are its focus on multiple interactions, its setting within a realistic design process, and its use of low levels of computer technology. After describing details of the designer’s media techniques, the paper discusses the practical and theoretical implications of the work.

title	Designing, CAD and CAD

summary	The general aim of our discussion is to analyze what has been changed in design process according to introducing the computers technology. For the better understanding of the design process evolution, we should precisely define start point - the traditional design process.Let's treat it as an iteration game between a designer and user. If we assume that the designing base is a reductive strategy, we can define six stages of it: 1.) To define a need; 2.) To formulate a task; 3.) To synthesize a design proposals; 4.) To analyze and optimize; 5.) To make a presentation. // The last stage - the presentation of designing proposals is the main factor of using computers in design process and creating definition of CAD as Computer Aided Drafting. According to this interpretation CAD has included four groups of activities: A.) Geometrical modelling; B.) Analysis; C.) Revision and estimation of design proposals; D.) Technical drawing preparing. // Unfortunately it has no connections with another meaning of CAD - Computer Aided Design because concerns every stage of design process except of creation of architectural form. On the other hand, computer enables us to improve the design process by permanent perception of designing forms and dynamic control over the transforming structure. Nowadays thanks to full-function sketching workstation and software like Fractal Design Painter a computer can be useful from the moment when the first line is drawing. It is possible, that the new generation of CAD software - CAD with Personality which connects computer models with picture transformation will enable CAD to be Computer Aided Design.

title	An integrated approach to CAD: modelling concepts in building design and construction
source	Design Studies 16 (3) (1995) pp. 327-347
summary	The ICON project is concerned with the creation of a generic information structure for the construction industry. A central feature of the information model is the use of object-oriented modelling techniques to allow information to be viewed from different 'perspectives' and at different levels of abstraction, according to the requirements of the user. This paper discusses the object modelling of concepts and information in the design area. Drawing on knowledge elicited from protocol analysis of the design activity, a series of interrelated object models has been developed, reflecting different perspectives and abstraction levels within the design domain. Three of these models (spatial design, physical design and structural design) are presented and their implications for the communication and sharing of information discussed.

title	Simulation of Shape, Light, Color and Material in Design
source	Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 417-426
doi	https://doi.org/10.52842/conf.ecaade.1995.417
summary	The purpose of this paper is to analyze the role of simulation in architectural design. The concept of simulation is taken over from physics, where analytical relationships are set up between measured phenomena and mathematical models. Computer visualization applies quantitative models to physical phenomena to simulate analytical aspects, and offers to the designer programs to evaluate, in CAD models, the visual qualities and the numerical quantities of the interactions between shape, light, color and material. Regarding the light-matter simulation, the paper presents recent developments in geometry which make it possible to visualize not only the surface appearance but also the in depth structure of building materials.

title	Linking the Virtual to Reality: CAD & Physical Modeling
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 303-311
summary	Using both study models and digital models for schematic design allows us to take advantage of the strengths of each. Models constructed manually benefit from spontaneous juxtapositions and serendipitous interactions with light and gravity. Converting these models into the digital realm allows the computer to take over in areas that it does best: geometric transformation, rigorous analysis, elaboration and co-ordination of details and complexity. As a project develops, CAD/CAM methods can generate forms or components for verifying the virtual representation. The paradigm of porting data to appropriate software tools needs to be extended to exporting out of and into the physical realm. Connecting to models in real space allows us to use senses that are not yet completely addressed by digital models.

title	GIS Software and Coordinated Project Information Systems - A Mechanism for Increasing the Effectiveness of 3D CAAD Models
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 389-397
summary	This paper reviews current 3D CAD building modelling by reference to a large ongoing case study, in which 3D building models and sites are used to generate coordinated drawing, schedule, and visualisation output. It focuses on barriers which current software interpose, preventing more complete use of 3D CAD to integrate building project information systems. Comparisons are made with tools and methodology developed in GIS, in which users make different selections as required from common databases, and it is argued that used in conjunction with 3D CAD building models, they could improve functionality and reduce barriers to effective deployment.

summary	In the early stages of the building design process not only building and site but also user activities and experiences are formed. This paper presents a development programme for CAAD where conceptual models of some fundamental characteristics of building, site and user organisation will be developed and implemented in a prototype CAAD-programme. The models are based both on empirical studies and an ontological Framework which is also used for organising the basic object structure of the prototype CAD program. The architectural design process has several characteristics which a CAAD-programme must support, e.g incremental determination of properties, change of scale and shift of focus. The research investigates how the design object and the user interface can be formed to serve this working method. One important field is to study the usefulness of the user organisation model for the brief and building management stages. The programming work for the prototypes is done with Smalltalk on Macintosh computers. The tests of the prototype includes spatial co-ordination of the three systems.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	AN EVOLUTIONARY ARCHITECTURE
source	London: Architectural Association
summary	In "An Evolutionary Architecture", John Frazer presents an overview of his work for the past 30 years. Attempting to develop a theoretical basis for architecture using analogies with nature's processes of evolution and morphogenesis. Frazer's vision of the future of architecture is to construct organic buildings. Thermodynamically open systems which are more environmentally aware and sustainable physically, sociologically and economically. The range of topics which Frazer discusses is a good illustration of the breadth and depth of the evolutionary design problem. Environmental Modelling One of the first topics dealt with is the importance of environmental modelling within the design process. Frazer shows how environmental modelling is often misused or misinterpreted by architects with particular reference to solar modelling. From the discussion given it would seem that simplifications of the environmental models is the prime culprit resulting in misinterpretation and misuse. The simplifications are understandable given the amount of information needed for accurate modelling. By simplifying the model of the environmental conditions the architect is able to make informed judgments within reasonable amounts of time and effort. Unfortunately the simplications result in errors which compound and cause the resulting structures to fall short of their anticipated performance. Frazer obviously believes that the computer can be a great aid in the harnessing of environmental modelling data, providing that the same simplifying assumptions are not made and that better models and interfaces are possible. Physical Modelling Physical modelling has played an important role in Frazer's research. Leading to the construction of several novel machine readable interactive models, ranging from lego-like building blocks to beermat cellular automata and wall partitioning systems. Ultimately this line of research has led to the Universal Constructor and the Universal Interactor. The Universal Constructor The Universal Constructor features on the cover of the book. It consists of a base plug-board, called the "landscape", on top of which "smart" blocks, or cells, can be stacked vertically. The cells are individually identified and can communicate with neighbours above and below. Cells communicate with users through a bank of LEDs displaying the current state of the cell. The whole structure is machine readable and so can be interpreted by a computer. The computer can interpret the states of the cells as either colour or geometrical transformations allowing a wide range of possible interpretations. The user interacts with the computer display through direct manipulation of the cells. The computer can communicate and even direct the actions of the user through feedback with the cells to display various states. The direct manipulation of the cells encourages experimentation by the user and demonstrates basic concepts of the system. The Universal Interactor The Universal Interactor is a whole series of experimental projects investigating novel input and output devices. All of the devices speak a common binary language and so can communicate through a mediating central hub. The result is that input, from say a body-suit, can be used to drive the out of a sound system or vice versa. The Universal Interactor opens up many possibilities for expression when using a CAD system that may at first seem very strange.However, some of these feedback systems may prove superior in the hands of skilled technicians than more standard devices. Imagine how a musician might be able to devise structures by playing melodies which express the character. Of course the interpretation of input in this form poses a difficult problem which will take a great deal of research to achieve. The Universal Interactor has been used to provide environmental feedback to affect the development of evolving genetic codes. The feedback given by the Universal Interactor has been used to guide selection of individuals from a population. Adaptive Computing Frazer completes his introduction to the range of tools used in his research by giving a brief tour of adaptive computing techniques. Covering topics including cellular automata, genetic algorithms, classifier systems and artificial evolution. Cellular Automata As previously mentioned Frazer has done some work using cellular automata in both physical and simulated environments. Frazer discusses how surprisingly complex behaviour can result from the simple local rules executed by cellular automata. Cellular automata are also capable of computation, in fact able to perform any computation possible by a finite state machine. Note that this does not mean that cellular automata are capable of any general computation as this would require the construction of a Turing machine which is beyond the capabilities of a finite state machine. Genetic Algorithms Genetic algorithms were first presented by Holland and since have become a important tool for many researchers in various areas.Originally developed for problem-solving and optimization problems with clearly stated criteria and goals. Frazer fails to mention one of the most important differences between genetic algorithms and other adaptive problem-solving techniques, ie. neural networks. Genetic algorithms have the advantage that criteria can be clearly stated and controlled within the fitness function. The learning by example which neural networks rely upon does not afford this level of control over what is to be learned. Classifier Systems Holland went on to develop genetic algorithms into classifier systems. Classifier systems are more focussed upon the problem of learning appropriate responses to stimuli, than searching for solutions to problems. Classifier systems receive information from the environment and respond according to rules, or classifiers. Successful classifiers are rewarded, creating a reinforcement learning environment. Obviously, the mapping between classifier systems and the cybernetic view of organisms sensing, processing and responding to environmental stimuli is strong. It would seem that a central process similar to a classifier system would be appropriate at the core of an organic building. Learning appropriate responses to environmental conditions over time. Artificial Evolution Artificial evolution traces it's roots back to the Biomorph program which was described by Dawkins in his book "The Blind Watchmaker". Essentially, artificial evolution requires that a user supplements the standard fitness function in genetic algorithms to guide evolution. The user may provide selection pressures which are unquantifiable in a stated problem and thus provide a means for dealing ill-defined criteria. Frazer notes that solving problems with ill-defined criteria using artificial evolution seriously limits the scope of problems that can be tackled. The reliance upon user interaction in artificial evolution reduces the practical size of populations and the duration of evolutionary runs. Coding Schemes Frazer goes on to discuss the encoding of architectural designs and their subsequent evolution. Introducing two major systems, the Reptile system and the Universal State Space Modeller. Blueprint vs. Recipe Frazer points out the inadequacies of using standard "blueprint" design techniques in developing organic structures. Using a "recipe" to describe the process of constructing a building is presented as an alternative. Recipes for construction are discussed with reference to the analogous process description given by DNA to construct an organism. The Reptile System The Reptile System is an ingenious construction set capable of producing a wide range of structures using just two simple components. Frazer saw the advantages of this system for rule-based and evolutionary systems in the compactness of structure descriptions. Compactness was essential for the early computational work when computer memory and storage space was scarce. However, compact representations such as those described form very rugged fitness landscapes which are not well suited to evolutionary search techniques. Structures are created from an initial "seed" or minimal construction, for example a compact spherical structure. The seed is then manipulated using a series of processes or transformations, for example stretching, shearing or bending. The structure would grow according to the transformations applied to it. Obviously, the transformations could be a predetermined sequence of actions which would always yield the same final structure given the same initial seed. Alternatively, the series of transformations applied could be environmentally sensitive resulting in forms which were also sensitive to their location. The idea of taking a geometrical form as a seed and transforming it using a series of processes to create complex structures is similar in many ways to the early work of Latham creating large morphological charts. Latham went on to develop his ideas into the "Mutator" system which he used to create organic artworks. Generalising the Reptile System Frazer has proposed a generalised version of the Reptile System to tackle more realistic building problems. Generating the seed or minimal configuration from design requirements automatically. From this starting point (or set of starting points) solutions could be evolved using artificial evolution. Quantifiable and specific aspects of the design brief define the formal criteria which are used as a standard fitness function. Non-quantifiable criteria, including aesthetic judgments, are evaluated by the user. The proposed system would be able to learn successful strategies for satisfying both formal and user criteria. In doing so the system would become a personalised tool of the designer. A personal assistant which would be able to anticipate aesthetic judgements and other criteria by employing previously successful strategies. Ultimately, this is a similar concept to Negroponte's "Architecture Machine" which he proposed would be computer system so personalised so as to be almost unusable by other people. The Universal State Space Modeller The Universal State Space Modeller is the basis of Frazer's current work. It is a system which can be used to model any structure, hence the universal claim in it's title. The datastructure underlying the modeller is a state space of scaleless logical points, called motes. Motes are arranged in a close-packing sphere arrangement, which makes each one equidistant from it's twelve neighbours. Any point can be broken down into a self-similar tetrahedral structure of logical points. Giving the state space a fractal nature which allows modelling at many different levels at once. Each mote can be thought of as analogous to a cell in a biological organism. Every mote carries a copy of the architectural genetic code in the same way that each cell within a organism carries a copy of it's DNA. The genetic code of a mote is stored as a sequence of binary "morons" which are grouped together into spatial configurations which are interpreted as the state of the mote. The developmental process begins with a seed. The seed develops through cellular duplication according to the rules of the genetic code. In the beginning the seed develops mainly in response to the internal genetic code, but as the development progresses the environment plays a greater role. Cells communicate by passing messages to their immediate twelve neighbours. However, it can send messages directed at remote cells, without knowledge of it's spatial relationship. During the development cells take on specialised functions, including environmental sensors or producers of raw materials. The resulting system is process driven, without presupposing the existence of a construction set to use. The datastructure can be interpreted in many ways to derive various phenotypes. The resulting structure is a by-product of the cellular activity during development and in response to the environment. As such the resulting structures have much in common with living organisms which are also the emergent result or by-product of local cellular activity. Primordial Architectural Soups To conclude, Frazer presents some of the most recent work done, evolving fundamental structures using limited raw materials, an initial seed and massive feedback. Frazer proposes to go further and do away with the need for initial seed and start with a primordial soup of basic architectural concepts. The research is attempting to evolve the starting conditions and evolutionary processes without any preconditions. Is there enough time to evolve a complex system from the basic building blocks which Frazer proposes? The computational complexity of the task being embarked upon is not discussed. There is an implicit assumption that the "superb tactics" of natural selection are enough to cut through the complexity of the task. However, Kauffman has shown how self-organisation plays a major role in the early development of replicating systems which we may call alive. Natural selection requires a solid basis upon which it can act. Is the primordial soup which Frazer proposes of the correct constitution to support self-organisation? Kauffman suggests that one of the most important attributes of a primordial soup to be capable of self-organisation is the need for a complex network of catalysts and the controlling mechanisms to stop the reactions from going supracritical. Can such a network be provided of primitive architectural concepts? What does it mean to have a catalyst in this domain? Conclusion Frazer shows some interesting work both in the areas of evolutionary design and self-organising systems. It is obvious from his work that he sympathizes with the opinions put forward by Kauffman that the order found in living organisms comes from both external evolutionary pressure and internal self-organisation. His final remarks underly this by paraphrasing the words of Kauffman, that life is always to found on the edge of chaos. By the "edge of chaos" Kauffman is referring to the area within the ordered regime of a system close to the "phase transition" to chaotic behaviour. Unfortunately, Frazer does not demonstrate that the systems he has presented have the necessary qualities to derive useful order at the edge of chaos. He does not demonstrate, as Kauffman does repeatedly, that there exists a "phase transition" between ordered and chaotic regimes of his systems. He also does not make any studies of the relationship of useful forms generated by his work to phase transition regions of his systems should they exist. If we are to find an organic architecture, in more than name alone, it is surely to reside close to the phase transition of the construction system of which is it built. Only there, if we are to believe Kauffman, are we to find useful order together with environmentally sensitive and thermodynamically open systems which can approach the utility of living organisms.

title	Incorporation of Natural Language Processing and a Generative System - An Interactive System that Constructs Topological Models from Spatial Descriptions in Natural Language
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 205-218
summary	The natural language processing technique and the spatial reasoning technique are incorporated to create a computational model representing the process of updating and maintaining the knowledge about spatial relations. An algorithm for the spatial reasoning is proposed. An interactive system that understands sentences describing spatial relations is implemented. The system determines the reference of an anaphoric or deictic expression from the literal meaning of the input and the implicit meaning derived from the literal meaning. The consistency of the spatial relations is maintained. The correct topological representations of the spatial relations are generated from well-formed descriptions.

title	The Search for the Logical Algorithm of the Town-planning Process
source	CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 275-282
summary	The creation of such models of material and spatial environment that can guarantee the most efficient passing of the virtual processes is considered to be one of the main goals for the town planning. But sometimes this goal is not achieved because of the far-fetched space organization accepted in the model, that does not always coincide with the real processes of vital activity. This report does not focus particularly on the damage which is caused by the realization of such defective models. But it is very important to find out the way for complete elimination of the reasons mentioned above. We should also take into account that means of cognition available at the moment are among the basic determiners, which define that "shear" of reality and also that comprehension level of objective laws governing this stage of social development. That is why our conception of the town-planning processes is in constant development and improvement: it gradually approximates to the truth, but, certainly, does not entirely perceive it.

doi	https://doi.org/10.52842/conf.ecaade.1995.331
summary	Contemporary multimedia research address the possibilities and consequences of integrating various techniques to produce single user based applications (singularity). There is a need for utilising current multimedia techniques; to explore the potential of multi-models (theoretically) to generate modelling information that could be shared simultaneously. The problems are confined to understanding and managing the issues that influence the so-called ´target and product models´. This paper introduces and elaborates on such problems. It provides a theoretical and another practical framework, the 3D-CAD Modelling Paradigm, based upon completed results of modelling. There is a suggested evidence that there might be advantages in standardising the process of modelling and knowledge representation. The paper stresses that the composition of a model should differ from another to reflect its unique characteristics (singularity). Though, it is essential that such models should conform and respond to the well defined and shared criteria (pluralism).

This system combines relatively simple 3-dimensional models (from a traditional CAD standpoint) with aerial photographs and street level video to create a realistic (down to plants, street signs and the graffiti on the walls) model of an urban neighborhood which can then be used for interactive fly and walk-through demonstrations.The Urban Simulator project is more than just the simulation software. It is a methodology which integrates existing systems such as CAD and GIS with visual simulation to facilitate the modeling, display, and evaluation of alternative proposed environments. It can be used to visualize neighborhoods as they currently exist and how they might appear after built intervention occurs. Or, the system can be used to simulate entirely new development.

summary	Product Modeling is considered to be an established concept not only for semantically based data exchange, but also for the specification of models, dealing with specific application requirements. The product model approach is regarded to be one step towards a new generation of Computer Aided Architectural Design, and to provide underlying means for enabling communication between different applications on a semantic level. After on overview about the background and the basis principles of product modeling, the authors discuss how product models can be used in commercial developments and in applied research projects.

title	SIMULATION - HOW DOES IT SHAPE THE MESSAGE?
source	The Future of Endoscopy [Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4], pp. 47-54
summary	Architectural simulation techniques - CAD, video montage, endoscopy, full-scale or smaller models, stereoscopy, holography etc. - are common visualizations in planning. A subjective theory of planners says "experts are able to distinguish between 'pure design' in their heads and visualized design details and contexts like color, texture, material, brightness, eye level or perspective." If this is right, simulation details should be compensated mentally by trained people, but act as distractors to the lay mind. Environmental psychologists specializing in architectural psychology offer "user needs' assessments" and "post occupancy evaluations" to facilitate communication between users and experts. To compare the efficiency of building descriptions, building walkthroughs, regular plans, simulation, and direct, long-time exposition, evaluation has to be evaluated. Computer visualizations and virtual realities grow more important, but studies on the effects of simulation techniques upon experts and users are rare. As a contribution to the field of architectural simulation, an expert - user comparison of CAD versus endoscopy/model simulations of a Vienna city project was realized in 1995. The Department for Spatial Simulation at the Vienna University of Technology provided diaslides of the planned city development at Aspern showing a) CAD and b) endoscopy photos of small-scale polystyrol models. In an experimental design, they were presented uncommented as images of "PROJECT A" versus "PROJECT B" to student groups of architects and non-architects at Vienna and Salzburg (n= 95) and assessed by semantic differentials. Two contradictory hypotheses were tested: 1. The "selective framing hypothesis" (SFH) as the subjective theory of planners, postulating different judgement effects (measured by item means of the semantic differential) through selective attention of the planners versus material- and context-bound perception of the untrained users. 2. The "general framing hypothesis" (GFH) postulates typical framing and distraction effects of all simulation techniques affecting experts as well as non-experts. The experiment showed that -counter-intuitive to expert opinions- framing and distraction were prominent both for experts and lay people (= GFH). A position effect (assessment interaction of CAD and endoscopy) was present with experts and non-experts, too. With empirical evidence for "the medium is the message", a more cautious attitude has to be adopted towards simulation products as powerful framing (i.e. perception- and opinion-shaping) devices.

title	AgentCAD for Cooperative Design
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 667-672
summary	AgentCAD is a network infrastructure of distributed CAD applications that facilitates the concurrent an cooperative interaction of several designers working together, possibly over several physical locations, on a design project. It provides a set of services and protocols that support the communications of distributed design information captured by CAD drawings, multiple design views, and design changes. It coordinates access to a common and multiple design models as well as the activities of designers based on captured knowledge of designers' tasks, capabilities, and interests, which characterize their behaviors. The idea of AgentCAD represents a departure from the usual way in which CAD applications are used as single-user tools, applied to one view of specific design problems. In describing the AgentCAD environment, we discuss the organization of AgentCAD, its communication model, and the cooperative interaction protocols for designers in the context of a design scenario.

title	ID'EST: An Integrated Modelling Framework for Management of Architectural Data
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 377-387
summary	An Integrated Design Environment, IDE, facilitates cooperation between different disciplines. The paper investigates the data modelling framework, distinguishes between homogeneous and heterogeneous model worlds, discusses the formal mapping mechanisms available to establish a heterogeneous model world, and introduces a way to incorporate CAD systems into IDE A prototype IDE has been developed to prove these methods. The ID'EST prototype comprises its own core data model, different schemas to cope with several design views, and interfaces to incorporate external CAD systems. A prototype architectural data model has been defined, that includes core data models and aspect models for enclosure system and spatial system. Conventional CAD systems can be integrated into ID'EST, if they are able to map data from the aspect models into their own data structure, and vice versa, on a high semantic level. The inherent methods of classifying data in CAD, layers, macros and attached attributes, have been used to retrieve product data from CAD data files. The usability of conventional CAD systems as data instantiation tools for IDE has been proved and a path has been shown, by which existing tools can be integrated into new technology solutions.

summary	Historically mock-up projecting turned out to be one of the bases of architectural education in the Moscow Architectural Institute. In spite of the fact, that technical progress did not pass over this Institute, introducing elements of computer techniques into the process of education, traditional methods do still prevail. In some sense it is a positive phenomenon, which does not allow this Institute to become ,one of the many typical ones", though in the epoch of global scientific and technical progress here this situation is forced. Under the economic conditions, established in this country, it is impossible to ensure such computer equipment, which would make the process of teaching students up-to-date methods of computer-aided design possible and really general, and make frontal employment of computers for solving complex design problems quite real. Now we can speak only about selective - optional teaching students mastering computer methods on the modern level. At the same time it was noted repeatedly, that essential defects are common to the traditional designing, especially when it concerns education; these defects are connected with a great degree of abstracting the model of the projected object (by the way this concerns also computer models), realized in the form of a small-scale mock-up. This is due to the representation of the projected object separated from the real environment as well as difference in the scales of the observer and the observed object. Mistakes in perception and appreciation caused in this way affect the efficiency of training disastrously. Luckily the available variety of sufficiently simple and cheap technical devices allows to overcome the mentioned defects to a considerable degree and combining these devices with personal computers makes it possible to enlarge their possibilities considerably. And at the same time due to the specific character of the employment it becomes unnecessary to have a lot of computers and the employed technologies turn out to be more "friendly" to the architect practically not demanding him to have complicated special knowledge. We mean special videocomputer technologies ("multimedia"), including the employment of periscope devices (environmental simulator or "telemaketoscope").

summary	Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.
