title	Modelling multiple views of design objects in a collaborative CAD environment
source	Computer-Aided Design, Vol. 28 (3) (1996) pp. 193-205
summary	Collaboration between designers in different disciplines is an increasingly important aspect in complex design situations, as exemplified in the AEC domain. CAD systems are essential for handling this complexitybut current CAD modelling technology is directed towards the production of a single product model. In the AEC environment, many disciplines are involved, each with its own concept of the design object. Eachsuch concept must be accommodated in any representation. This paper presents the ideas behind the representation of multiple concepts from an underlying description of a design such that the inter- andintra-discipline views of that design can be formed dynamically. These ideas are based on different functional contexts. Functional subsystems are introduced as an adjunct to design prototypes. An example showshow these functional subsystems are related to the design elements and how they allow for the formation of the various concepts. Thus the representation of the functional properties of design objects is theunderlying basis for the formation of different concepts.

title	Spatial objects and intelligent agents in a virtual environment
source	Automation in Construction 5 (3) (1996) pp. 141-150
summary	Many CAD software tools are available today for architectural design. They are useful for drafting, but tools that support design development in an early stage are still missing. In a conceptual phase of the design aspects other than precision and measurements become important. With today's knowledge and technological possibilities new ways of interaction, different data structures and intelligent support tools can be implemented. This article describes our research on new ways to support the design development in an early stage. The concept of modelling spaces, the virtual modelling tool and the integration of intelligent agents are described.

title	The Development of a Virtual Studio Environment to Support Collaborative Building Design
source	Design, Synergy, Collaboration - selected papers from DEcon Conference
summary	This paper describes the development of a virtual studio environment to support collaborative working in the domain of building design. By applying and extending the real-world design studio model within the Internet-based distributed computing environments, the virtual studio concept has been refined as computerised settings, which integrate both the dispersed human designers and the distributed CAD applications. The hope is to achieve the similar effect as physical co-presence while providing extra advantages such as the support for automatic communication archiving and being less obtrusive than sharing a physical office. Like its real-world counterpart (which usually consists of the office, desks, file cabinets, instruments etc), such a virtual studio consists of the several major components, including a multi-user graphical user interface displaying the shared virtual workspace on each designer's workstation, distributed multimedia databases and CAD tools for processing the domain tasks, and rich human-human interaction facilities supporting a variety of communication modes. Advance distributed object computing technologies (0MG CORBA in particular) have been adopted for modelling and implementing the distributed systems, W3 (world-wide-web) technologies have also been exploited for constructing the distributed multi-media databases and an image communication kit. In contrast to the traditional CAD integration which is usually focused solely on the well-structured technical part of the product and process, the described research advocates a human-centred systems development strategy in which design is first of all taken as a process of social construction.

title	A conceptual model for design management
source	Computer-Aided Design, Vol. 28 (1) (1996) pp. 33-49
summary	Design management is a very important topic for every state-of-the-art CAD/CAE environment. By definition, the concept of design management addresses a set of functions which build, maintain, display, manageand enforce relationships among the data and among the design tools that are involved in a project. From this definition, straightforward user and functional requirements are derived. Then, a model which fulfilsmany of the requirements, especially in the data management part, is described. Allthe considerations are free from implementation details, so that modelling topics are not confused with programming problems. Ouranalysis is mapped on electronic hardware design; most of the concepts, however, are valid also in many other engineering fields.

title	A Virtual Reality Design Environment with Intelligent Objects and Autonomous Agents
source	H.J.P. Timmermans (ed.), Design and Decision Support Systems in Architecture and Urban Planning Conference, Vol. 1: Architecture Proceedings, pp. 132-142
summary	New technological achievements and research results allow for the creation of innovative design tools for architects, that do not originate from paper-based paradigms but instead make optimised use of the present technology and programming concepts. The core of our system is comprised of an intuitive interactive modelling tool. It runs in a virtual reality set-up, where the user can use 3D glasses to experience rooms and 3D input devices to model in three dimensions. The interface is free from widget-like buttons or menus, so that the user is undisturbed when moving into the virtual world of the design. The system can also run in a distributed fashion, so that a number of users can look at and modify the same design. The 3D model can be generated in a sketch-like fashion using solids and voids, void modelling turns out to be very valuable for architectural design. The objects in this system can contain forms of intelligence to produce such behaviour as: falling because of gravity, collision avoidance, and autonomous motion. Interactive behaviour can also be assigned to the objects. Autonomous Agents are added to the system to enhance the designer support. These are agents that enhance the virtual environment, agents that take over tasks, and agents that help to test the design. The system shows new interface and interaction approaches that support the architectural design process intelligently.

summary	The introduction of the computer into architectural studies has resulted in innovative pedagogical approaches to design education. In recent years we have employed a teaching approach in which the student models the formalization of design knowledge in a computerized environment and experiments with the formal processing of this knowledge in the generation of designs. Interacting with the computer in the generation of designs requires making design knowledge explicit and formalized. Knowledge modeling is an approach to design and education in which the designer models the design thinking involved in the making of the object. In this process appropriate computational technology is essential to support and enhance certain phenomena of reasoning. From the pedagogical point of view such computational design environment appear also to enhance design learning and performance through the capability gained in computer modelling. In this respect, there is an analogous impact on the potential of design knowledge environments which can support design performance in practice. In this paper we consider the Internetas a potential design knowledge environment. The nature of the Net as a medium for the representation, storage and accessing of design knowledge is presented and various research issues are introduced. The potential of this new medium as a resource for design learning, design practice and design collaboration derives from the attributes of the technology. We elaborate on the appropriateness of certain attributes of the medium as a potential design environment. Future possibilities of the Net as a shared design resource are proposed. Considerations of the Net as a collaboratively constructed design resource as well as a medium for collaborative design are introduced.

title	An information management model for concurrent construction engineering
source	Automation in Construction 5 (4) (1996) pp. 343-355
summary	Projects in the construction industry are increasingly characterised by large numbers of actors working concurrently at different locations and using heterogeneous technologies. In order to support this kind of collaborative engineering, project information needs to be conceptually modelled throughout its lifecycle, along with the events that impact upon it by causing state changes. There exists, therefore, an urgent need to provide a flexible framework in which the highly interleaved and interactive events and transactions inherent in complex construction projects can be managed effectively. This paper addresses these issues by proposing such a conceptual framework consisting of four levels of abstraction and functionality governed by the COMMIT (Construction Modelling and Methodologies for Intelligent inTegration of information) Information Management Model (CIMM). A comprehensive presentation of the CIMM (which tackles issues such as versioning, notification, object rights and ownership) is given. The CIMM also facilitates the recording of the intent behind construction project decisions, thereby providing a complete project history. Finally, the model is illustrated through two proposed scenarios dealing with selected objects' lifecycles during design stages and actor transaction management.

summary	Computer Aided Design means not only aiding the preparation of technical documentation for building purposes or for the presentation of architectural design. The application of computer technology has a deeper meaning, when used for the creative modelling of designed objects and spaces. This article will help to define and describe Computer Parametric Modelling as an example of creative computer use. All conclusions presented in this article are based on a four year long working experience using the computer program MODEL; utilising parametric modelling in architectural and town-planning design by the author of this article. This program was created by the author and he is the only user at the present time, but it is hoped that it will be available for general use in the future.

title	Collaborative Design in Virtual Space - GreenSpace II: A Shared Environment for Architectural Design Review
doi	https://doi.org/10.52842/conf.acadia.1996.165
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 165-179
summary	Design reviews and discussions are fundamental to the process of design. The ability to digitally represent three dimensional space in real-time is a new and potentially persuasive method for reviewing and analyzing a design proposal. The development of real-time rendering engines and network protocols supporting distributed interaction makes possible the idea of a shared virtual environment for architectural collaboration. This paper presents a system which facilitates the review of an architectural design between multiple participants who are remotely distributed.

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.

summary	The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

title	Shared understanding in computer-supported collaborative design
source	Computer-Aided Design, Vol. 28 (3) (1996) pp. 183-192
summary	We propose that computer-support for collaborative design requires a shared understanding of the design artifact among a design team. The development and support for this shared understanding builds on currentdevelopments and research in AI, CAD, CSCW and computational models of design. The shared understanding should be an explicit representation in order to be effectively shared. The explicit representation shouldcomprise both a visual representation and a semantic model. In this paper we present an architecture for computer-supported collaborative design that distinguishes between a shared visual representation and a sharedunderlying representation. The development of the underlying representation combines graphical and semantic objects than can be abstracted and aggregated as a tangled hierarchy.

title	Functional Integration in CAD Systems
source	Advances in Engineering Software, 25, 103-109
summary	This paper examines the issue of integration in CAD systems and argues that for integration to be effective, it must address the functional aspects of a CAD system. It discusses the need for integrated systems and, within a structural engineering context, identifies several facets of integration that should be targeted. These include 2-D drafting and 3-D modelling, graphical and non-graphical design information, the CAD data structure and its user interface, as well as integration of the drafting function with other engineering applications. Means of achieving these levels of integration are briefly discussed and a prognosis for the future development of integrated systems explored. Particular attention is paid to the emergence (and potential role) of `product models' which seek to encapsulate the full range of data elements required to define completely an engineering artefact.

summary	The structures for the storage of data in CAD systems influence to a large extent the effectiveness of the system. This paper reviews the wide range of data structures and database management systems (DBMS) available for structuring CAD data. Examples of basic data types are drawn from the MODULA-2 language. The relationship between these basic data types, their composite structures and the classical data models (on which many DBMS are based) is discussed, and the limitations of existing DBMS in modelling CAD data highlighted. A set of requirements for CAD database management systems is drawn up and the emerging role of product models (which seek to encapsulate the totality of data elements required to define fully an engineering artefact) is explored.

source	CAD Creativeness [Conference Proceedings / ISBN 83-905377-0-2] Bialystock (Poland), 25-27 April 1996 pp. 37-39
summary	One of the ways to improve design solutions is to make some variants of the design at the early stage of working on it. Such a process can be even more successful when it is based on computer techniques followed by comprehensive assessments of variants. The assessment of 3-dimensional and spatial solutions of industrial buildings is based on two groups of indices- technical and economical indices and the quality ones (criteria). Most of the indices belong to the first group while the second one is rather small. The list of the indices used in the procedure was worked out mainly for the assessment of finished projects and only a small part was worked out for the assessment of draft solutions.

title	Teaching Architectural Composition Through the Medium of Virtual Reality Modelling
source	Approaches to Computer Aided Architectural Composition [ISBN 83-905377-1-0] 1996, pp. 91-102
summary	This paper describes an experimental teaching programme to enable architectural students in the early years of their undergraduate study to explore their understanding of the principles of architectural composition, by the creation and experience of architectural form and space in simple virtual reality environments. Principles of architectural composition, based upon the ordering and organisation of typological architectural elements according to established rules of composition, are introduced to the students, through the study of recognised works of architectural design theory. Virtual reality modelling is then used as a tool by the students for the testing and exploration of these theoretical concepts. Compositional exercises involving the creation and manipulation of a family of architectural elements to create form and space within a three dimensional virtual reality environment are carried out using Superscape VRT, a PC based virtual reality modelling system. The project seeks to bring intuitive and immersive computer based design techniques directly into the context of design theory teaching and studio practice, at an early stage in the architectural education process.

summary	The course on CAAD at the KU Leuven is part of the course on design methodology and theory from which it is the most recent and natural extension. Attached to this course a series of assignments has been developed which bring the students in 45 hours to a non-trivial level of acquaintance with CAAD. Our assignments are primarily directed towards practice. They are built on top of AutoCAD to which we have added in-house developments in order to focus on specific pedagogical goals within a very limited time. After a general introduction on Windows (file management) and AutoCAD (basics) students make the following assignments (main pedagogical goals in between brackets). colophon (working with blocks), detail (2D-drawing, hatching, editing), facade design using a built-in system of proportion (slides, scriptfile), extraction (linking alphanumerical and graphical entities), container (level of detail, icon menus, viewports), surface modelling (modelling 3D-objects with surfaces), fractal tree (recursion in Autolisp), solid modelling (Leicester engineering building), lighting (integration of drawing and computation of illumination levels), pressure lines in an arc (interactive design of an arc), demos. The paper presents and comments these assignments and shows results from the last 2 years.

title	STEP approach applied to a design support system in construction, within the context of concurrent engineering
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	The purpose of this article is to show that a building project design requires a concurrent engineering approach. Therefore, a concurrent preparation phase which requires the choice of a product approach applied to the building trade will be defined. During the building project design, handled data are multiple; current models, used to define, to represent, and to communicate these data, are insufficient. To solve these problems, the achievement of this approach has to be supported by reliable models and computer systems. These systems have to integrate data set and treatments one. The models and tools used in this concurrent preparation must to take into account the standards set in the domain, in particular the STEP (STandard Exchange for Product model data) project. STEP technology uses a methodology of product data definition which can be applied to a particular domain: the application protocol approach. This methodology will be applied to data and support system modelling, so that a concurrent approach to the building trade can be achieved. Finally the specification and the software architecture of this system will be presented.

title	Conjoint measurement in virtual environment: a framework
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Conjoint analysis (also called stated preference analysis) involves the use of designed hypothetical choice situations to measure individuals' preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives (product profiles) are generated and presented to respondents, who are requested to express their degree of preference for these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of product profiles. This paper describes a framework for a conjoint analysis system in a virtual environment. Product profiles are generated in a virtual environment and respondents are requested to choose in that virtual environment the product profile they prefer. Advantages of a virtual environment in this area of research include 3D presentation, improved experience and the possibility to include measurable attributes such as time and sound.
