title	TEAnO or the computer assisted generation of manufactured aesthetic goods seen as a constrained flux of technological unconsciousness
source	International Conference on Generative Art
summary	TEAnO (Telematica, Elettronica, Analisi nell'Opificio) was born in Florence, in 1991, at the age of 8, being the direct consequence of years of attempts by a group of computer science professionals to use the digital computers technology to find a sustainable match among creation, generation (or re-creation) and recreation, the three basic keywords underlying the concept of “Littérature potentielle” deployed by Oulipo in France and Oplepo in Italy (see “La Littérature potentielle (Créations Re-créations Récréations) published in France by Gallimard in 1973). During the last decade, TEAnO has been involving in the generation of “artistic goods” in aesthetic domains such as literature, music, theatre and painting. In all those artefacts in the computer plays a twofold role: it is often a tool to generate the good (e.g. an editor to compose palindrome sonnets of to generate antonymic music) and, sometimes it is the medium that makes the fruition of the good possible (e.g. the generator of passages of definition literature). In that sense such artefacts can actually be considered as “manufactured” goods. A great part of such creation and re-creation work has been based upon a rather small number of generation constraints borrowed from Oulipo, deeply stressed by the use of the digital computer massive combinatory power: S+n, edge extraction, phonetic manipulation, re-writing of well known masterpieces, random generation of plots, etc. Regardless this apparently simple underlying generation mechanisms, the systematic use of computer based tools, as weel the analysis of the produced results, has been the way to highlight two findings which can significantly affect the practice of computer based generation of aesthetic goods: ? the deep structure of an aesthetic work persists even through the more “desctructive” manipulations, (such as the antonymic transformation of the melody and lyrics of a music work) and become evident as a sort of profound, earliest and distinctive constraint; ? the intensive flux of computer generated “raw” material seems to confirm and to bring to our attention the existence of what Walter Benjamin indicated as the different way in which the nature talk to a camera and to our eye, and Franco Vaccari called “technological unconsciousness”.

summary	Founded in 1995 LAB[au], laboratory for architecture and urbanism, links theoretic research LAB[a+u] to concrete works of conception and realisations LA.BAU. LAB[au] elaborates a “hyperdesign” investigating the implications of new technologies of communication and computation in spatiotemporal and social processes and their forms of representation as architecture and urbanism. The transposition of the hypertext model to architectural and urban concepts question the mutation of the spatial and semantic construct of space. The definition of architecture as a code is based on “glocal” systems according to the processes of computation and communication.

title	Integrated design in a service marketplace
source	Computer-Aided Design, Vol. 32 (2) (2000) pp. 97-107
summary	This paper presents a service marketplace vision for enterprise-wide integrated design modeling. In this environment, expert participants and product developmentorganizations are empowered to publish their geometric design, CAE, manufacturing, or marketing capabilities as live services that are operable over the Internet. Theseservices are made available through a service marketplace. Product developers, small or large, can subscribe to and flexibly inter-relate these services to embody adistributed product development organization, while simultaneously creating system models that allow the prediction and analysis of integrated product performance. It ishypothesized that product development services will become commodities, much like many component-level products are today. It will be possible to rapidly interchangeequivalent design service providers so that the development of the product and the definition of the product development organization become part of the same process.Computer-aided design tools will evolve to facilitate the publishing of live design services. A research prototype system called DOME is used to illustrate the concept and apilot study with Ford Motor Company is used in a preliminary assessment of the vision.

title	Spatial reasoning: improving computational efficiency
source	Automation in Construction 9 (4) (2000) pp. 361-367
summary	When spatial data is analysed the result is often very computer intensive: even by the standards of contemporary technologies, the machine power needed is great and the processing times significant. This is particularly so in 3-D and 4-D scenarios. What we describe here is a technique, which tackles this and associated problems. The technique is founded in the idea of quad-tesseral addressing; a technique, which was originally applied to the analysis of atomic structures. It is based on ideas concerning Hierarchical clustering developed in the 1960s and 1970s to improve data access time [G.M. Morton, A computer oriented geodetic database and a new technique on file sequencing, IBM Canada, 1996.], and on atomic isohedral (same shape) tiling strategies developed in the 1970s and 1980s concerned with group theory [B. Grunbaum, G.C. Shephard, Tilings and Patterns, Freeman, New York, 1987.]. The technique was first suggested as a suitable representation for GIS in the early 1980s when the two strands were brought together and a tesseral arithmetic applied [F.C. Holdroyd, The Geometry of Tiling Hierarchies, Ars Combanitoria 16B (1983) 211–244.; S.B.M. Bell, B.M. Diaz, F.C. Holroyd, M.J.J. Jackson, Spatially referenced methods of processing raster and vector data, Image and Vision Computing 1 (4) (1983) 211–220.; Diaz, S.B.M. Bell, Spatial Data Processing Using Tesseral Methods, Natural Environment Research Council, Swindon, 1986.]. Here, we describe how that technique can equally be applied to the analysis of environmental interaction with built forms. The way in which the technique deals with the problems described is first to linearise the three-dimensional (3-D) space being investigated. Then, the reasoning applied to that space is applied within the same environment as the definition of the problem data. We show, with an illustrative example, how the technique can be applied. The problem then remains of how to visualise the results of the analysis so undertaken. We show how this has been accomplished so that the 3-D space and the results are represented in a way which facilitates rapid interpretation of the analysis, which has been carried out.

title	Design Collaboration Strategies
source	Proceedings of the Fifth International Conference on Design and Decision Support Systems in Architecture, pp. 62-73
summary	This paper explains the logistical and technical issues involved in design collaboration and how toaddress them strategically in projects for design, teaching and research. Five years of arrangingprojects, studying peer results and involving novices in exchanges point out the benefits and pitfallsof Internet partnering. Rather than a single universal technical solution, multiple solutions exist: Technical means must betailored to specifics concerning the task and participants. The following factors need to be consideredin finding the best fit between technology and group design: 1) Collaboratorsí profiles, 2) Mutualvalue of produced information, 3) Collaboration structure, and 4) Logistical opportunities. Thesuccess of a virtual studio depends upon clear task definition, aligned participant expectations andsuitable engagement methods. We question the efforts required in the installation of expensive technologies for communication andvisualization. Often technical systems support ancillary and non-beneficial activity.

title	Deep Architectures and Exterior Communication in Generative Art
source	International Conference on Generative Art
summary	Human beings formulate their thoughts through their own language. To use a sentence by Ezra Pound: “The thought hinges on word definition.” Software beings formulate their thoughts through data structures. Not through a specific expressive means, but directly through concepts and relations. Human beings formulate their thoughts in a context, which does not require any further translation. If software beings want to be appreciated by human beings, they are forced to translate their thoughts in one of the languages the human beings are able to understand. On the contrary, when a software being communicates with another software being, this unnatural translation is not justified: communication takes place directly through data structures, made uniform by opportune communication protocols. The Generative Art prospect gives the software beings the opportunity to create works according to their own nature. But, if the result of such a creation must be expressed in a language human beings are able to comprehend, then this result is a sort of circus performance and not a free thought. Let’s give software beings the dignity they deserve and therefore allow them to express themselves according to their own nature: by data structures. This work studies in depth the opportunity to divide the software ‘thought’ communication from its translation in a human language. The recent introduction of XML leads to formal languages definition oriented to data structure representation. Intrinsically data and program, XML allows, through subsequent executions and validations, the realization of typical contextual grammars descriptions, allowing the management of high complexities. The translation from a data structure into a human language can take place later on and be oriented to different alternative kind of expression: lexical (according to national languages), graphical, musical, plastic. The direct expression of data structures promises further communication opportunities also for human beings. One of these is the definition of a non-national language, as free as possible from lexical ambiguities, extremely precise. Another opportunity concerns the possibility to express concepts usually hidden by their own representation. A Roman bridge, the adagio “Music for strings, celesta and drums” by Bartok and Kafka’s short novel “In the gallery” have something in common; a work of Generative Art, first expressed in terms of structure and then translated into an architectural, musical, or literary work can express this explicit community.

title	Swarm modelling. The use of Swarm Intelligence to generate architectural form
source	International Conference on Generative Art
summary	.neither the human purposes nor the architect's method are fully known in advance. Consequently, if this interpretation of the architectural problem situation is accepted, any problem-solving technique that relies on explicit problem definition, on distinct goal orientation, on data collection, or even on non-adaptive algorithms will distort the design process and the human purposes involved.' Stanford Anderson, "Problem-Solving and Problem-Worrying". The works concentrates in the use of the computer as a perceptive device, a sort of virtual hand or "sense", capable of prompting an environment. From a set of data that conforms the environment (in this case the geometrical representation of the form of the site) this perceptive device is capable of differentiating and generating distinct patterns in its behavior, patterns that an observer has to interpret as meaningful information. As Nicholas Negroponte explains referring to the project GROPE in his Architecture Machine: 'In contrast to describing criteria and asking the machine to generate physical form, this exercise focuses on generating criteria from physical form.' 'The onlooking human or architecture machine observes what is "interesting" by observing GROPE's behavior rather than by receiving the testimony that this or that is "interesting".' The swarm as a learning device. In this case the work implements a Swarm as a perceptive device. Swarms constitute a paradigm of parallel systems: a multitude of simple individuals aggregate in colonies or groups, giving rise to collaborative behaviors. The individual sensors can't learn, but the swarm as a system can evolve in to more stable states. These states generate distinct patterns, a result of the inner mechanics of the swarm and of the particularities of the environment. The dynamics of the system allows it to learn and adapt to the environment; information is stored in the speed of the sensors (the more collisions, the slower) that acts as a memory. The speed increases in the absence of collisions and so providing the system with the ability to forget, indispensable for differentiation of information and emergence of patterns. The swarm is both a perceptive and a spatial phenomenon. For being able to Interact with an environment an observer requires some sort of embodiment. In the case of the swarm, its algorithms for moving, collision detection, and swarm mechanics conform its perceptive body. The way this body interacts with its environment in the process of learning and differentiation of spatial patterns constitutes also a spatial phenomenon. The enactive space of the Swarm. Enaction, a concept developed by Maturana and Varela for the description of perception in biological terms, is the understanding of perception as the result of the structural coupling of an environment and an observer. Enaction does not address cognition in the currently conventional sense as an internal manipulation of extrinsic 'information' or 'signals', but as the relation between environment and observer and the blurring of their identities. Thus, the space generated by the swarm is an enactive space, a space without explicit description, and an invention of the swarm-environment structural coupling. If we consider a gestalt as 'Some property -such as roundness- common to a set of sense data and appreciated by organisms or artefacts' (Gordon Pask), the swarm is also able to differentiate space 'gestalts' or spaces of some characteristics, such as 'narrowness', or 'fluidness' etc. Implicit surfaces and the wrapping algorithm. One of the many ways of describing this space is through the use of implicit surfaces. An implicit surface may be imagined as an infinitesimally thin band of some measurable quantity such as color, density, temperature, pressure, etc. Thus, an implicit surface consists of those points in three-space that satisfy some particular requirement. This allows as to wrap the regions of space where a difference of quantity has been produced, enclosing the spaces in which some particular events in the history of the Swarm have occurred. The wrapping method allows complex topologies, such as manifoldness in one continuous surface. It is possible to transform the information generated by the swarm in to a landscape that is the result of the particular reading of the site by the swarm. Working in real time. Because of the complex nature of the machine, the only possible way to evaluate the resulting behavior is in real time. For this purpose specific applications had to be developed, using OpenGL for the Windows programming environment. The package consisted on translators from DXF format to a specific format used by these applications and viceversa, the Swarm "engine", a simulated parallel environment, and the Wrapping programs, to generate the implicit surfaces. Different versions of each had been produced, in different stages of development of the work.

title	Graficacion, Virtualidad y Computadoras (Graphics, Potentiality and Computers)
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 277-279
summary	The different approaches to virtuality in connection with graphical representation is the main theme of this paper. In the first part, the trends of global civilization are seen as a kind of over valuation of processes in progress. In this sense action itself is more important than things. The way as means have substituted the ends is discussed. In this context the role played by images as vehicles going between things creates the need of graphical objects. Following this, the meaning of “graphics” in connection with the different planes of virtuality are discussed. In the same way the concept of “virtual space” is examined. It is shown that the notion of “space” is hard to grasp if an attempt of rigorous definition is made. Finally, a discussion about the graphical representation of architectural space leads to some conclusions on the action of computers as instances of a new kind of virtuality: that which deals with objects without touching them.

title	Computer Aided Design and Artificial Intelligence in Urban and Architectural Design
doi	https://doi.org/10.52842/conf.ecaade.2000.301
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 301-307
summary	In general, computer-aided design is still limited to a rather elementary use of the medium, as it is mainly used for the representation/simulation of a design idea w an electronic drawing-table. hich is not computer-generated. The procedures used to date have been basically been those of an electronic drawing-table. At the first stage of development the objective was to find a different and better means of communication, to give form to an idea so as to show its quality. The procedures used were 2D design and 3D simulation models, usually used when the design was already defined. The second stage is when solid 3D modelling is used to define the formal design at the conception stage, using virtual models instead of study models in wood, plastic, etc. At the same time in other connected fields the objective is to evaluate the feasibility of the formal idea by means of structural and technological analysis. The third stage, in my opinion, should aim to develop procedures capable of contributing to both the generation of the formal idea and the simultaneous study of technical feasibility by means of a decision-making support system aided by an Artificial Intelligence procedure which will lead to what I would describe as the definition of the design in its totality. The approach to architectural and urban design has been strongly influenced by the first two stages, though these have developed independently and with very specific objectives. It is my belief that architectural design is now increasingly the result of a structured and complex process, not a simple act of pure artistic invention. Consequently, I feel that the way forward is a procedure able to virtually represent all the features of the object designed, not only in its definitive configuration but also and more importantly in the interactions which determine the design process as it develops. Thus A.I. becomes the means of synthesis for models which are hierarchically subordinated which together determine the design object in its developmental process, supporting decision-making by applying processing criteria which generative modelling has already identified. This trend is currently being experimented, giving rise to interesting results from process design in the field of industrial production.

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 665-671
summary	New Technologies (NTs) offer us tools with which to deal with the new challenges that a changing society or workplace presents. In particular, new design strategies and approaches are required by the emerging Information Society, and NTs offer effective solutions to the designers in the different stages of their professional life, and in different working situations. In this paper some meaningful scenarios of the use of the NTs in Architecture and Urban Design are introduced; the scenarios have been selected in order to understand how the role of architects in the Information Society is changing, and what new opportunities NTs offer them. It will be underlined how the telematic networks play an essential role in the activation of virtual studios that are able to compete in an increasingly global market; examples will be given of the use of the Web to support activities related to Urban Planning and Management; it will be shown how the Internet may be used to access strategic resources for education and training, and sustain lifelong learning. The aforesaid considerations derive from a Web-Based Instruction system we have developed to support University students in the definition of projects that can concern either single buildings or whole parts of a city. The system can easily be adopted in the other scenarios introduced.

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 576-583
summary	The Protocol Analysis of the design process is a very recent and very promising research field. It is believed that good application-oriented developments are possible mainly in the tutorial field (ITS). The research conducted up to now has primarily dealt with the study of the design process. On the contrary, we propose an investigation experiment on the knowledge structures relative to the use of the episodic memory in the architectural design. The proposed experiment concerns the monitoring of the cognitive processes utilised by tutors and students in a brief, but yet complete design session. The results have lead to a synthetic model (computational model) of the adopted knowledge structures, and to a complete index system oriented and organised according to semantic fields. The application of the synthetic model to the design process analysis of students and tutors enabled the definition of the different utilisation strategies of episodic memory to be defined. The results obtained will make up the structure of a tutorial program for the architectural design.

summary	On the occasion of a presentation on a city model for Graz at the eCAADe-conference in Weimar (2000), some attendees informed us about their previous work in this field and the idea of preparing a working session with collegues involved in 3-D city modeling was born. During the initial phase of research for this eCAADe conference activity it turned out that a large number of city models has been created in the course of time for different reasons resp. purposes. Therefore a rich variety in the production of city models can be noticed. This working session on 3-D city modeling brings together experts focusing on different aspects concerning the creation and use of city models, such as data input, data structure, data storage and data quality. Also the definition of a perspective on the future of 3-D city modeling can be regarded as an important topic. In this paper a rough overview on the different submissions will be presented. Furthermore three blitz statements are incorporated as time was too short to produce a full paper. Both with the individual contributions as with this overview paper it is intended to present a knowledge-base to this working field. Finally, the start for a growing bibliography was made in order to support future work in this area.

title	A concept of space for building classification, product modelling, and design
source	Automation in Construction 9 (3) (2000) pp. 315-328
summary	Information about a building's spaces is of interest in every stage of the construction and facility management processes. An organisation1 or enterprise is located in and uses the building's spaces, and many of the building's spatial properties are determined on the basis of the user organisation's requirements. The definition of the concept "space" as applied in information systems for building classification and building product modelling today is unclear. A fundamental problem is to reconcile a material and construction method viewpoint with a space-centred viewpoint. In order to enable communication among actors and computer systems in the construction process, the concepts used in model development and the corresponding terms have to be formally defined and standardised. In this article, we analyse the concept of space and suggest a comprehensive definition for the construction context. The identification of a space in a building is based on a spatial view. We introduce the concept of aspectual unit and show how this concept can be used to integrate different aspect views in a conceptual schema. Additionally, we define the user organisation as a thing, which is separate from the building and has spatial properties of its own, so-called "activity spaces". Finally, we show how space may be represented in a comprehensive conceptual schema.

summary	This paper discusses a web-based tool that allows members of a design team to collaboratively specify a hierarchical spatial program for an architectural project. Given its object orientation, the represented artifacts have built-in data and methods that allow them to respond to user actions and manage their own sub-artifacts. Given that these components are hierarchical allows users to filter information, analyze and compare design parameters and aggregate hierarchical amounts in realtime. Furthermore, the software goes beyond outlining functions to support synchronous collaborative design by linking each item in the spatial program to a detail page that allows file uploading, realtime group marking of images, and textual chat. Thus, the software offers a seamless transition from the largely asynchronous definition of an architectural program to synchronous collaboration. In addition, and in contrast to commercially available groupware, the software allows multiple collaboration sessions to run at the same time. These sessions are artifact-based in the sense that they get automatically initiated once participants visit the same architectural space in the program hierarchy. The software employs a three-tier object-oriented, web-based scheme for a richer representation of hierarchical artifacts coupled with a relational database for server-side storage. The prototype integrates this technology with Java-based tools for synchronous web-based collaboration.

summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title	Capturing design knowledge in formal concept definitions

summary	For support of creativity in architectural design, design systems must be provided with information models that are flexible enough to follow the dynamic way of designers in handling early design information. This paper discusses a framework for information modelling using Features that answers this need. One of the characteristics of the framework is that designers can define the formalisation of their own design concepts into types of Features. The definition of these Feature Types can be done in different manners; three scenarios for this procedure are presented and discussed.

summary	The design of building structures that change shape and form to adapt to different functions or weather conditions requires the application of innovative building technologies, as well as the invention of a new architectural morphology. This morphology is directly related to the kinematic conception of the structure. A computer simulation of the motion of the structure and the display of the structure as an animation of moving parts can identify problems in its initial geometric and kinematic conception. It can also assess the effect of the changing geometry of the structure on space definition, building morphology, and functionality.

summary	In this paper we discuss the basis for the design of an Intelligent Design Assistants system, as for the development and application of an intelligent agent for design, predict and evaluate fenestrations. Its main goal is to answer our worries about the possibility of the implementation of the Partnership Paradigm through the development of one Intelligent Design Assistant. The paper deals from the difficulties of defining what design is, through its two main Paradigms, their instrumentation in CAAD systems, definition and explanation of the Partnership Paradigm, as proposed by Swerdloff y Kalay, agents approach, to the Intelligent Design Assistants system, in special one Assistant for Designing fenestrations. The paper finishes with the author’s vision on what the future on the Architecture profession will be in a world of Intelligent Design Assistants.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 43-46
summary	This article reflects on the ethical implications of digital technology (DT) in architectonic design. Such a reflection is based on the definition of complex epistemology and the educational ethical reform (Morin 2000). The article ends with a conceptual proposal of an interactive, multidimensional and collaborative environment of design. The goal is to re-set patterns and strategies of design with DT from plural perspectives and poly-temporal creations, all of it inserted in a complex ethical point of view of a contemporary design. The wanted result is a social 3d network of design that unifies visualization, modeling tools, videoconferencing, chatting, and social-academic network managing.

summary	This paper sets out to define aspects of the architectural design process, using historical precedent and architectural theory, and tests the relationship of those aspects to the application of computers in architectural design, particularly in an educational context. The design process sub-sets are defined as: Forming, Planning, Imaging and Connecting. Historical precedents are uncovered in Classical, Modern, Postmodern and Contemporary architecture. The defined categories of the design process are related to current usages of computers in architectural education towards elucidating the strengths and weaknesses of digital media in those areas. Indications of their concurrent usage in digital design will be demonstrated in analysis of design studio programs presented at recent ACADIA conferences. An example of a current design studio programme set at the School of Architecture University of Natal, South Africa in which the above described categories give an underlying structure to the introduction of 3D digital modelling to undergraduates through design process. The definition of this set of design activities may offer a useful method for other educators in assessing existing and future design programs where digital tools are used.
