title Sketches of thought
source MA: MIT Press, Cambridge
summary Much of the cognitive lies beyond articulate, discursive thought, beyond the reach of current computational notions. In Sketches of Thought, Vinod Goel argues that the cognitive computational conception of the world requires our thought processes to be precise, rigid, discrete, and unambiguous; yet there are dense, ambiguous, and amorphous symbol systems, like sketching, painting, and poetry, found in the arts and much of everyday discourse that have an important, nontrivial place in cognition. Goel maintains that while on occasion our thoughts do conform to the current computational theory of mind, they often are -- indeed must be - vague, fluid, ambiguous, and amorphous. He argues that if cognitive science takes the classical computational story seriously, it must deny or ignore these processes, or at least relegate them to the realm of the nonmental. As a cognitive scientist with a design background, Goel is in a unique position to challenge cognitive science on its own territory. He introduces design problem solving as a domain of cognition that illustrates these inarticulate, nondiscursive thought processes at work through the symbol system of sketching. He argues not that such thoughts must remain noncomputational but that our current notions of computation and representation are not rich enough to capture them. Along the way, Goel makes a number of significant and controversial interim points. He shows that there is a principled distinction between design and nondesign problems, that there are standard stages in the solution of design problems, that these stages correlate with the use of different types of external symbol systems; that these symbol systems are usefully individuated in Nelson Goodman's syntactic and semantic terms, and that different cognitive processes are facilitated by different types of symbol systems.

title Dynamic Generation of Design Plans at the Brief Stage
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 219-228
summary The traditional approach to design and construction suffers from many limitations. As the technology becomes more available to the average users, the need for an effective and efficient solution has never been greater. This paper introduces an alternative approach to the life cycle of construction projects "application controlled process". Based on this approach, a framework for an Integrated Construction Environment (ICE) has been developed and implemented in a prototype demonstrator "SPACE" (Simultaneous Prototyping for An integrated Construction Environment). This paper is only concerns with those parts of the ICE which are relevant to the dynamic generation of design drawings. The NIRMANI system aims at generating a schematic design by retrieving previous design solutions that match the problem specification from a multimedia case library. While the Bay Design Systems aims at re-adjusting the produced design solution to minimise construction problems.

title Hypertext Between Research and Teaching: An Experience in a Didactic Building Technology Laboratory
doi https://doi.org/10.52842/conf.ecaade.1995.003
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. 3-12
summary IPER (hypertext for the knowledge of building patrimony) is the result of a research developed with C.N.R. (National Research Institute). The aim of IPER is to provide the knowledge, the description and the management of one or more historical buildings for public or private institutions. IPER allowed us to improve our methodology of building analysis, covering various disciplinary fields, in two different systems. (1.) the first one, synthetic and suitable for a group of historical buildings, (2.) the second one, complex and particularly made for monumental buildings. // This experience is related to the new regulation of teaching architecture in Italy made in 1993. The main novelty is the introduction of the laboratories with the contemporary presence of two or three teachers of different disciplines, working together with the students on the same project with different approaches. This opportunity allowed us to introduce the "knowledge engineer" as a teacher in the laboratory of building technology. IPER is given to the students with the aim of experimenting and solving the theoretical and practical difficulties that students of different years may encounter in the knowledge and representation of buildings and in the organisation of all the data from the case study.

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. 187-198
summary This paper reports on current research in the field of architectural design and knowledge- based systems, through the conception and implementation of two software tools operating as a part of an integrated hypermedia environment denominated PatriArch. Main concern of this set of tools operating in PatriArch is the support of design since the very beginning, in that phase of not yet correctly explored or interpretated constraints and of scarcely specified goals, in which an initial solution model - provisionally composed of fragments of supposed fitting ideas - for the design theme has to take place. The creative activity of the designer is assumed as an 'intentional planning activity' that represents the acquired level of knowledge of the network of connections defining the nature, function, shape in the space etc. of the increasingly integrated solution-model: the final design will be an evolution of this - and other competitive and concurrent - models. PatriArch is meant to be the environment containing and allowing the representation of this evolution through its ability of linking the fragments of designers' knowledge, supported by an integrated relational data base: Sysinfo. These works were conceived inside an educational software development program for architecture students.

title What can real-time positioning do for construction?
source Automation in Construction 5 (2) (1996) pp. 79-89
summary New technologies are now available that can rapidly measure three-dimensional coordinates of objects. The integration of these fast 3-D Real-time Position Measurement (D-RtPM) devices and CAD (3D-RtPM/CAD) technologies can be viewed as a better tool for surveyors or as a means to change the most fundamental concepts of the construction industry. 3D-RtPM/CAD is a better surveying tool; however, 3D-RtPM/CAD as the basis for fundamental change within the construction industry is the issue. There are several potential technologies that can provide real-time position measurement. This paper will limit presentation to two of these. The first is based on recent developments in Global Positioning Systems. The second is a new laser-based product, OdysseyTM (Odyssey is a trademark of Spatial Positioning Systems, Inc.). Odyssey received the NOVA award in March, 1995 because of its recognized performance enhancement to the construction industry. These positioning systems provide the capability for equipment and crafts people to view the project from a graphical representation in which they see their position interactively updated. Potential benefits to the construction industry are presented. The research needed achieving maximum benefits of these systems is also presented.

title A Brief Note on Virtual Space

summary In its efforts to represent space, and then create architecture on the basis of this representation, humanity has taken three major steps. STEP 1. Representation of space in the form of a drawing or model; representations compared to the mental vision and then redrawn or remodelled, until the vision takes the shape of a finished building. This technology of design" followed different conventions, depending on the epoch. In the Middle Ages the method of approximation by triangles was introduced. The Renaissance used Projection, Elevation and Cross-Section. In order to construct a building, a flat, abstract representation is used, supplemented by a model showing spatial relations and a verbal description, impossible to convey graphically. STEP 2. Methods as in Step 1, but, beginning in the 1970s, with the use of computers, which allows also for the gradual integration of these methods in one program. Theoretically speaking, all necessary data can be now recorded, visualized, animated, etc., on a PC class computer. The design-aid software is based on the method of creating a 3D model of the whole building, and then generating the rest (projections, cross-sections) from it. STEP 3. The above step have - brought us to near- perfection in photorealistic representation of space, which remains, however only a 2D abstraction from 3D space. The next step, which is now taking place before (and in?) our very eyes, is to use systems which bring us directly into 3D space.

summary The rapid development of the potentialities of multimedia imposes a reflection about its use in teaching architecture. Multimedia is multifaceted and each facet deserves a particular attention inasmuch as it can change the traditional approach to learning. A direct experience of an architectural work can be simulated with a impact far stronger than an experience trough photographs, drawings and books can do. But, as every positive fact can have in certain cases also some negative consequences. the intensity of the participation to an experience structured by someone else can leave less space to a personal approach to the object of the presentation. The same problem is posed if we consider the structure of an hypertext. The essence of the hypertext lies in the net of relationships between very different kinds of documents that it is able to manage in order to express the complexity of its theme. But who has to create the net, the teacher choosing the relationship that he thinks important or the learner to build a personal image of the hypertext matter. It is an old question about the two faces of teaching: transmitting knowledge or giving the learner the instruments to build by oneself his store of knowledge. Easy and trivial answer that both approaches can be useful. The accomplishment of a multimedial sequence of average complexity requires at present a lot of time. Hence, to be convenient, it is to be used many times, then by many students. The effectiveness of the tool partly depends on the rapidity with which it can be constructed. Speeding it up would allow to use this kind of tools with the same easiness than mare traditional means of representation. Besides those general considerations a check is to do on the peculiarities, if any, of the use of multimedia in the different disciplines of the formative curriculum of an architect. This is theme of our thirteenth conference. The programme has been articulated into sessions, dealing separately with history teaching, design teaching and research. Of course the sessions dealing with design are more numerous than the other, since design is the axis of teaching architecture. The presented paper cover a large arc of arguments, dealing with many facets of the proposed themes with plenty of examples and documentation on practical experiences. constituting a corpus of great usefulness for any operator in the field of architectural teaching.

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 Multidimensional curve fitting to unorganized data points by nonlinear minimization
source Computer-Aided Design, Vol. 27 (1) (1995) pp. 48-58
summary Many papers have addressed the problem of fitting curves to data points. However, most of the approaches are subject to a restriction that the data points must be ordered.The paper presents a method for generating a piecewise continuous parametric curve from a set of unordered and error-filled data points. The resulting curve not only providesa good fit to the original data but also possesses good fairness. Excluding the endpoints of the curve, none of the connectivity information needs to be specified, thuseliminating the necessity of an initial parameterization. The standard regularization method for univariate functions is modified for multidimensional parametric functions andresults in a nonlinear minimization problem. Successive quadratic programming is applied to find the optimal solution. A physical model is also supplied to facilitate anintuitive understanding of the mathematical background.

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.

summary This paper is a survey of current research into computer modeling of buildings. Just as much, however, it is a contribution to a debate on the future of this field of research (and as such expresses the author's opinions, rather than mere facts). It is suggested that more research should be conducted in a top-down "'problem-driven" (rather than in a bottom-up. "technology-driven") manner. As the goal of future research, ten desirable system properties are proposed and grouped together under three headings: integration. intelligence", and compliance. A critical survey of the current state-of-the-art of computer modeling of buildings is given, to assess how far we are from systems with such properties. On that background problems are discussed which are major obstacles to the proposed kind of systems (hence good starting points lot problem-driven research and some ways of approaching these problems are briefly evaluated.

summary Emergence is the process of making properties which were not explicitly represented in a computational system explicit. This paper presents two approaches to graphical emergence suitable or implementation in a CAAD system. It presents processes for shape emergence - the interpretation of shapes which were not intentionally placed there by the designer - and shape semantics emergence - the interpretation of patterns of shape into structures which were not intentionally there by the designer. Examples of both processes and their use are given.

title The Role of Computers in Synchronous Collaborative Design
source Proceedings of the 14th International Congress on Cybernetics. Namur, Belgium: International Association for Cybernetics, 1995, pp. 71-76
summary In this paper we discuss the role of computers in supporting real-time synchronous design among geographically dispersed team members using the global network of computers known as the Internet. To enable efficient and functional synchronous design activity, we advocate a new generation of design-oriented software that combines collaboration technologies with a meaningful and parsimonious representation scheme. We are particularly interested in supporting the early design phases, wherein many of the most important decisions are made and collaboration is most important. These activities are crucial to the evolution and quality of the final design, and they are receptive to and can benefit from computer support. Furthermore, these are precisely the areas where current CAD systems are weakest. As a general theoretical direction, our emphasis is not on integrated databases, but rather on shared protocols of interaction that are independent of implementation and storage schemes. Our first experimental phase involved the simultaneous development and testing of prototypes for a Synchronous Collaborative Design Environment (SYCODE) on heterogeneous computer systems at two geographically dispersed sites. The applications were developed independently, based on a verbal description of protocols, with minimal sharing of actual source code. Though their user interfaces and implementation details are different, these prototypes allow multiple users to share a virtual design space - both within and between the remote sites - in which to create and manipulate architectural elements.

summary The design problem has a multi-disciplinary nature and the design itself evolves as solutions are attempted by the designer. To support inter-disciplinary communication of design concepts and decisions, the integration of relevant CAAD tools is essential. Based upon a large set of design criteria and all corresponding knowledge, with the help of computer aided design tools, the result could be highly effective and novel. The integration of CAAD tools should be performed on the basis of generating better solutions by enabling designers to manipulate and appraise various solutions quickly and with a minimum of effort. The proposed system provides the foundations for a seamless and continuous working environment for architects and building engineers through a data modelling module, an integrated data management framework and various design tools. In the environment, stand-alone design tools can be plugged-in in order to access information stored in central databases. The suggested data modelling module helps integrated CAAD systems represent and exchange domain dependent design information at a semantic level, such as exchanging components and features of a building rather than graphical primitives. The suggested data management framework supports the straight-forward mechanisms for controlling the data representation through the inter-connected modules and design tools.

title CAD Users Integration – A Current Problem
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 93-103
summary In just about every field of human activities, actions which cover the design processes and the development of "a product", demand the participation of people presenting different professions and specialization. Designers using CAD techniques, usually apply different programs and even computer systems. This means that quite a large number of different applications, realising various elementary tasks, may be used during architectural design process. Very seldom data generated by a single designer, may be used by another one presenting a different specialization and using a different program. As each one of them makes a lot of changes during the design process, the need for a free exchange of the computer generated data may be seen easily. Hitherto proposed solutions of the integration of CAD systems users may be qualified in two following groups: 1.) Those based on a single integrated CAD system; 2.) Those based on a neutral data transfer format.

summary This paper presents an approach to developing the computer aided architectural design systems investigating architectural semantics paradigm and void modeling representation as a method. A prototypical system called FRED(Facile Roof Editor & Designer) was developed incorporating structural logic and characteristics of roof in its basic representation and its operational behavior constrained by distinct attributes of a roof. Design of Hip, Pitch, Multi-level, and Flat roofs in Solid and Shell forms was made possible by extracting from an existing building or creating them as independent entities. The implementation successfully demonstrates that incorporating architectural semantics in the basic representation of a CAD system allows architects to create and test roof morphology fairly quickly, accurately, and fluidity for ideation.

summary Extremes converge. Life blossoms on the boundary. All creative thinking, architectural or mathematical, is essentially the some. Today legions of dull computers take over the role of renaissance giants in integrating all ways of thinking. On the sensual level, computer art is often indistinguishable from computer simulations of physical processes, such as fractals representing chaos. On the logical level, all information boils down to the language of bits, sequences of O's and I's or X's and Y's if you like- there just has to be two of them, like Adam and Eve at the beginning of mankind. Creating means synthesizing, composing, constructing a whole from elements. But often the starting point, the finish, the middle stages and methods are fuzzy, vague, ill- defined-ore all yet to be discovered or conceived. It is like groping in a dark labyrinth, searched and created at the same time. There are many branches to discover and explore, many dead ends forcing retreat, no guarantee of a solution, and even no clear idea of what a solution might be. It is a trial- and-error, generate-and-test, back-and-forth, top-down and bottom-up, global and local, inductive and deductive, rigorous at times and fuzzy most of the time, ameba-like process or bunch of processes. In this, creative, perspective both architecture and mathematics become experimental sciences: as such they require laboratories. Computer systems (hardware plus software) supply today the necessary environment, ways and means. To the happy user of a general-purpose platform, straddling the architecture-mathematics boundary-with one leg on a general-purpose computer-aided design system, like AutoCAD, and the other leg on a general-purpose mathematical system, like Mathematica, the essential unity of creatively doing both architecture and mathematics is hard to overlook.

title Retrieval of Similar Layouts in FABEL using AspecT
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 617-626
summary In the FABEL project several approaches have been developed and published for retrieving similar cases in the domain of architectural design. In this paper we want to focus on a short description and foremost on integration of these approaches. We will introduce the most important approaches. As a first step towards integration, we suggest decomposing them into their main parts: representation of cases, similarity function and retrieval component. Using the first two parts each approach in a new search algorithm operating on a generic data structure, we built a shell called AspecT for an easy integration. We are positive that one can never have fully considered all aspects of a design. Therefore, we describe an open framework to define new aspects and to apply them depending on the context. Unfortunately, openness brings some difficulties along with it. One can not predict the importance of an aspect, until the situation assessment of the query is completed. In other words, it is impossible to define a static distribution of aspect weights that fits for all purposes. As a consequence, one can not predefine a static structure on the case base to speed tip retrieval processes. Dealing with this problem, we developed and published a special search algorithm that passes through a multidimensional case base, finding the best fitting cases within a short amount of time. This algorithm does not need any predefined structure on the case base except aspect specific relations between cases. Creativity of inventing new aspects of cases should not be hindered but one can ask whether or not a certain aspect are worth being regarded in searching for useful cases. The shell AspecT offers a tool to evaluate aspects. At first, formal criteria influence the initial weights of aspects but later on, the contribution of an aspect to find user accepted cases, determines the survival fitness of an aspect. The rule for living or dying is simple. Seldom used aspects disappear, whereas others become stronger. A short description regarding this work is given in last part.

summary This research work is being financed by the "Instituto de Ciencias de la Educacion, I. CE., Universidad Politécnica de Valencia, U.P.V. and currently taking place at the "Taller2 de Proyectos Arquitectdnicos." We have placed CAD systems on drafting tables, so students can learn to apply different media and tools, both digital and traditional, in their design processes. To integrate CAD systems into the design studio we have developed a methodology upon which to relate the "Mechanics of the digital tool," with the often elusive and seldom explicit, "Mechanics of designing". We see architectural design as a process that can benefit from the use of computer systems through modelling (representation), and rendering (static or dynamic visualization). Digital modelling tools are powerful instruments to simulate and visualize (perceive) formal and spatial arrangements, under certain conditions of superficial appearance and light. Geometry composition, texture, light projection, rendering and animation, are the keys to understanding a digital modelling system as an extension of our design process. We introduce and explain each one of these categories, as it applies to architectural design and to three dimensional CAD systems. We present samples of student work following this method.

title Backtracking Decisions within a Design Process: a Way of Enhancing the Designer's Thought Process and Creativity
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 573-587.
summary This paper proposes a way computer sciences could contribute to stimulate the designer’s reflexive thought. We explore the possibility of making use of backtracking devices in order to formalize the designer’s thought process. Design, as a process of creating an object, cannot be represented by means of a linear timeline. Accordingly, the backtracking processes we are discussing here are not based on a linear model but rather on a non-linear structure. Beyond the notion of undoing and redoing commands within CAD packages, the backtracking process is seen as a way to explore and record several alternate options. The branches of the non-linear model can be seen as pathways made of sequential decisions. The designer creates and explores these pathways while making tentative moves towards an architectural solution. Within the design process, backtracking enables the designer to establish and act on a network of interrelated decisions. This notion is fundamental. It is quite obvious that information, in order to be meaningful, must occupy a specific place within an informational network. A data, separated from its context, is devoid of interest. By the same token, a decision takes on significance solely in combination with other decisions. In this paper, we examine what kinds of decisions are involved within a design process, how they are connected, and what could be the best ways to formalize the relationships. Our goal is to experiment ways that could enable the designer and his/her collaborators to get a clearer mental picture of the network of decisions aforementioned. The non-linear model can be seen as a graph structure. The user moves wherever he/she wants through the branches of the structure to establish the network of decisions or to get reacquainted with a previous design process. As a matter of fact, it can act in both ways: to reassess or to confirm a decision. On the one hand, the designer can go back to previous states, reconsider past choices, and eventually modify them. On the other hand, he/she can move forward and revisit a given sequence of decisions, so as to recapture the essence of a previous design process. It goes without saying that knowledge regarding the design process is constructed by the designer from his/her own experiences. Since the designer’s perception evolves as time goes by, the network of decisions constitutes a model that is continuously questioned and restructured. The designer does not elaborate solely an architectural object, but also an evolving model formalizing the way he/she achieved his/her aim. As Le Moigne (1995) pointed out, the model itself produces knowledge; afterwards, the designer can examine it so as to get a clearer mental picture of his/her own cognitive processes. Furthermore, it can be used by his/her collaborators in order to understand which thread of ideas led the designer to a given visual result, and eventually resume or reorient the design process. In addition to reflecting on the ideological implications inherent to this questioning, we take into account the feasibility of such a research project. From a more technical point of view, in this paper we will describe how we plane to take up the challenge of elaborating a digital environment enabling backtracking processes within graph structures. Furthermore, we will explain how we plane to test the first trial version of the new environment with potential users so as to observe how they respond to it. These experiments will be conducted in order to verify to what extend the methods we are proposing are able to i) enhance the designer’s creativity and ii) increase our understanding of designer’s thought process.
