title Generic Representations - Typical Design without the Use of Types
source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 117-133
summary The building type is a (knowledge) structure that is both recognised as a constitutive cognitive element of human thought and as a constitutive computational element in CAAD systems. Questions that seem unresolved up to now about computational approaches to building types are the relationship between the various instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed functional use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called 'prototypes') face problems clarifying these questions. It is proposed in this research not to focus on a definition of 'type,' but rather to investigate the role of knowledge connected to building types in the design process. The basic proposition is that the graphic representations used to represent the state of the design object throughout the design process can be used as a medium to encode knowledge of the building type. This proposition claims that graphic representations consistently encode the things they represent, that it is possible to derive the knowledge content of graphic representations, and that there is enough diversity within graphic representations to support a design process of a building belonging to a type. In order to substantiate these claims, it is necessary to analyse graphic representations. In the research work, an approach based on the notion of 'graphic units' is developed. The graphic unit is defined and the analysis of graphic representations on the basis of the graphic unit is demonstrated. This analysis brings forward the knowledge content of single graphic representations. Such knowledge content is declarative knowledge. The graphic unit also provides the means to articulate the transition from one graphic representation to another graphic representation. Such transitions encode procedural knowledge. The principles of a sequence of generic representations are discussed and it is demonstrated how a particular type - the office building type - is implemented in the theoretical work. Computational work on implementation part of a sequence of generic representations of the office building type is discussed. The paper ends with a summary and future work.

summary The existing Caad systems limit designers creativity by constraining them to work with prototypes provided by the system's knowledge base. Most think of computers as drafting machines and consider CAAD models as merely proposals for future buildings. But this kind of thinking (computers as simple drafting machines) seems to be a way without future. New media demands new process and new process demands new media. We have to give some thougt to impact of CAAD on the design process and in which part of it CAAD can add new value. In this paper there will be considered two ways of using of computers. First - creation of architectural form in an architect's mind and projects visualisation with using renderings, animation and virtual reality. In the second part - computer techniques are investigated as a medium of creation. Unlike a conventional drawing the design object within computer has a life of its own. In computer space design and the final product are one. Computer creates environments for new kind of design activities. In fact, many dimensions of meaning in cyberspace have led to a cyberreal architecture that is sure to have dramatic consequences for the profession.

title PCIS: a piece-based construction information system on the world wide web
source Automation in Construction 6 (4) (1997) pp. 287-298
summary This paper describes a piece-based construction information system organized as a hypergraphic virtual environment on the World Wide Web. An array of cubes on the site's animated splash-page acts as a directory to a collection of data-theaters that give this information its virtual form. A mouse click on one of these cubes leads to an orthographic model of the object to be constructed. This model is an index to a database of scaled drawings, animations, and specifications. The index is hypergraphic because a click on the image of one of the pieces of the model leads to a data page that provides information about that piece in the context of its assembly. Panels surround the index to act as an interface to projections of the pieces of the object. These projections include elevations, plans, slices, and dimensioned details. A click on the elevation-panel leads to information on finishes, framing, and construction of each face of the object. From above, the plan-panel shows roofing, framing, floor plan, foundation layout, excavation, and utilities as an animation of the construction process. There are also animated slice-panels that cut through the object to give heights and materials. A click on one of these panels leads to two-dimensional drawings and details of the actual construction. The orthographic index morphs to a framed VR environment where the model can be turned and viewed in perspective. A click on one of the pieces of the model in this information the VR environment leads to specifications and manufacturing information about the materials of its construction. The user accesses this information through a tool-palette to communicate with design team members. In this way, the team can coordinate the document's development, review progress, and make changes to the information system. This breaks the notion of a construction document as an object-of-exchange and suggests the use of the computer as a medium of communication that facilitates the design and construction process.

summary The concept of ODE (Open Design Environment) and corresponding system were presented in 1991. Then the new concept of NODE. which is networked version of ODE. was generated to make wide area collaboration in 1994. The aim of our research is to facilitate the collaboration among the various people involved in the design process of an urban or architectural project. This includes various designers and engineers, the client and the citizens who may be affected by such a project. With the new technologies of hyper medium, network, and component architecture, we have developed NODE system and applied in practical use of the collaboration among the various people. This study emphasizes the interactive 3-D design tool of NODE which is able to make realistic and realtime presentation with interactive interface. In recent years, ProjectFolder of NODE system, which is a case including documents, plans, and tools to proceed project., is created in the World Wide Web (WWW) and makes hyper links between a 3-D object and a text, an image. and other digital data.

title AIA CAD layer guidelines
source Washington, DC: The American Institute of Architects Press
summary The power and potential of computer-aided design (CAD) is based on the ability to reuse and share information. This is particularly true in building design and construction, a field that involves extensive information and teamwork between a variety of consultants. CAD provides both a common medium of exchange and a tool for producing the documentation required for construction and management. The key to realizing the potential of CAD is using common organizing principles. In particular, standard organization of files and layers is essential for efficient work and communication. Virtually all CAD systems support the concept of layers. This function allows graphic information to be grouped for display or plotting purposes. Intelligent use of layers can reduce drawing time and improve drawing coordination. By turning selected layers on or off, a variety of different plotted sheets can be produced. The layer is the basic CAD tool for managing visual information. By making it possible to reuse information, layers reduce drawing time and improve coordination. Layers and the new class libraries and object data complement, rather than compete with each other. Using layers to manage the visual aspects of graphic entities, with class libraries and object data to store the non-graphic data, gives architects an efficient way to work in CAD.

source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 3-13
summary The impact of computing on architecture receives little reflective judgment, its role either being negated or over-emphasized. To one group of architects, it is not desirable that the machine should influence the object. Another, mostly younger group, takes the impact for granted, without much reflection on its underlying reasons. The smallest group - mostly in academia - is interested in actively defining the impact of computing on design and in defining a new kind of architecture. The paper will explore the relation between computer and architecture on three levels, in which the machine has the role of an instrument, a medium, and a partner. It will demonstrate a serious deficit in education regarding the new roles of computing in design.

summary A model of human-machine design interaction is presented. The model is based on synchrony of actions as it relates to designing, presenting, and discussing a design object over an electronic medium. The model descriptively accommodates existing technologies and areas of CAD research. The model prescriptively illuminates future CAD vis. the Web. The model is based on 3 factors : synchrony, presence, activity; and 2 players : human and machine. Future technologies are considered in terms of the a shifting role of the machine (the computer and the net) from server to agent to actor.

title Generic representations : an approach for modelling procedural and declarative knowledge of building types in architectural design
source Eindhoven University of Technology
summary The building type is a knowledge structure that is recognised as an important element in the architectural design process. For an architect, the type provides information about norms, layout, appearance, etc. of the kind of building that is being designed. Questions that seem unresolved about (computational) approaches to building types are the relationship between the many kinds of instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called ‘prototypes’) face problems clarifying these questions. The research work at hand proposes to investigate the role of knowledge associated with building types in the design process. Knowledge of the building type must be represented during the design process. Therefore, it is necessary to find a representation which supports design decisions, supports the changes and transformations of the design during the design process, encompasses knowledge of the design task, and which relates to the way architects design. It is proposed in the research work that graphic representations can be used as a medium to encode knowledge of the building type. This is possible if they consistently encode the things they represent; if their knowledge content can be derived, and if they are versatile enough to support a design process of a building belonging to a type. A graphic representation consists of graphic entities such as vertices, lines, planes, shapes, symbols, etc. Establishing a graphic representation implies making design decisions with respect to these entities. Therefore it is necessary to identify the elements of the graphic representation that play a role in decision making. An approach based on the concept of ‘graphic units’ is developed. A graphic unit is a particular set of graphic entities that has some constant meaning. Examples are: zone, circulation scheme, axial system, and contour. Each graphic unit implies a particular kind of design decision (e.g. functional areas, system of circulation, spatial organisation, and layout of the building). By differentiating between appearance and meaning, it is possible to define the graphic unit relatively shape-independent. If a number of graphic representations have the same graphic units, they deal with the same kind of design decisions. Graphic representations that have such a specifically defined knowledge content are called ‘generic representations.’ An analysis of over 220 graphic representations in the literature on architecture results in 24 graphic units and 50 generic representations. For each generic representation the design decisions are identified. These decisions are informed by the nature of the design task at hand. If the design task is a building belonging to a building type, then knowledge of the building type is required. In a single generic representation knowledge of norms, rules, and principles associated with the building type are used. Therefore, a single generic representation encodes declarative knowledge of the building type. A sequence of generic representations encodes a series of design decisions which are informed by the design task. If the design task is a building type, then procedural knowledge of the building type is used. By means of the graphic unit and generic representation, it is possible to identify a number of relations that determine sequences of generic representations. These relations are: additional graphic units, themes of generic representations, and successive graphic units. Additional graphic units defines subsequent generic representations by adding a new graphic unit. Themes of generic representations defines groups of generic representations that deal with the same kind of design decisions. Successive graphic units defines preconditions for subsequent or previous generic representations. On the basis of themes it is possible to define six general sequences of generic representations. On the basis of additional and successive graphic units it is possible to define sequences of generic representations in themes. On the basis of these sequences, one particular sequence of 23 generic representations is defined. The particular sequence of generic representations structures the decision process of a building type. In order to test this assertion, the particular sequence is applied to the office building type. For each generic representation, it is possible to establish a graphic representation that follows the definition of the graphic units and to apply the required statements from the office building knowledge base. The application results in a sequence of graphic representations that particularises an office building design. Implementation of seven generic representations in a computer aided design system demonstrates the use of generic representations for design support. The set is large enough to provide additional weight to the conclusion that generic representations map declarative and procedural knowledge of the building type.

title An electronic design assistance tool for case-based representation of designs
source Automation in Construction 6 (4) (1997) pp. 265-274
summary In precedent based design, solutions to problems are developed by drawing from an understanding of landmark designs. Many of the key design operations in this mode are similar to the functionalities present in case-based reasoning systems: case matching, case adapting, and case representation. It is clear that a rich case-base, encoding all major product types in a design domain would be the centerpiece of such an approach. EDAT (Electronic Design Assistance Tool) is intended to assist in precedent based design in the studio with the potential of expansion into the office setting. EDAT has been designed using object oriented system development methods. EDAT was used in a design studio at Carnegie Mellon University, during Spring 1996.

summary We have arrived an important juncture in the history of computing in our profession: This history is long enough to reveal clear trends in the use of computing, but not long to institutionalize them. As computers peremate every area of architecture - from design and construction documents to project administration and site supervision - can “virtual practice” be far behind? In the old days, there were basically two ways of architects working. Under stress. Or under lots more stress. Over time, someone forwarded the radical motion that the job could be easier, you could actually get more work done. Architects still have been looking for ways to produce more work in less time. They need a more productive work environment. The ideal environment would integrate man and machine (computer) in total harmony. As more and more architects and firms invest more and more time, money, and effort into particular ways of using computers, these practices will become resistant to change. Now is the time to decide if computing is developing the way we think it should. Enabled and vastly accelerated by technology, and driven by imperatives for cost efficiency, flexibility, and responsiveness, work in the design sector is changing in every respect. It is stands to reason that architects must change too - on every level - not only by expanding the scope of their design concerns, but by altering design process. Very often we can read, that the recent new technologies, the availability of computers and software, imply that use of CAAD software in design office is growing enormously and computers really have changed the production of contract documents in architectural offices.

title The incorporation of construction history in architectural history: the HISTCON interactive computer program
source Automation in Construction 6 (4) (1997) pp. 275-285
summary Current teaching methods for architectural history seldom embrace building technology as an essential component of study. Accepting the premise that architectural history is a fundamental component to the overall architectural learning environment, it is argued that the study of construction history will further enhance student knowledge. This hypothesis created an opportunity to investigate how the study of construction history could be incorporated to strengthen present teaching methods. Strategies for teaching architectural history were analyzed with the determination that an incorporation of educational instructional design applications using object-oriented programming and hypermedia provided the optimal solution. This evaluation led to the development of the HISTCON interactive, multimedia educational computer program. Used initially to teach 19th Century iron and steel construction history, the composition of the program provides the mechanism to test the significance of construction history in the study of architectural history. Future development of the program will provide a method to illustrate construction history throughout the history of architecture. The study of architectural history, using a construction oriented methodology, is shown to be positively correlated to increased understanding of architectural components relevant to architectural history and building construction.

title Hierarchical Decomposition of Architectural Computer Models
doi https://doi.org/10.52842/conf.caadria.1997.197

summary Architectural models can be represented in a hierarchy of complexity. Higher level or more complex architecture structures are then designed by repetitively instantiating libraries of building blocks. The advantages are that the object can be achieved in modular fashion and any modification to the definition of a building block can be easily propagated to all higher level objects using the block. Unfortunately, many existing representations of architectural models are monolithic instead of hierarchical and modular, thus, making the reuse of models very difficult and inefficient. This paper describes a research project on developing a tool to decompose a monolithic architectural model into elementary building blocks and then create a hierarchy in the model representation. The tool provides a graphical interface for the visualization of a model and a cutting plane. An associated algorithm will then automatically detach parts of the model into building blocks depending on where the user is applying the cutting plane. Studies will also be made on dividing more complex models employing spherical and NURBS surfaces.

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.).

summary The architectural design business is marked by a progressive increase in operators all cooperating towards the realization of building structures and complex infrastructures (Jenckes, 1997). This type of design implies the simultaneous activity of specialists in different fields, often working a considerable distance apart, on increasingly distributed design studies. Collaborative Architectural Design comprises a vast field of studies that embraces also these sectors and problems. To mention but a few: communication among operators in the building and design sector; design process system logic architecture; conceptual structure of the building organism; building component representation; conflict identification and management; sharing of knowledge; and also, user interface; global evaluation of solutions adopted; IT definition of objects; inter-object communication (in the IT sense). The point of view of the research is that of the designers of the architectural artefact (Simon, 1996); its focus consists of the relations among the various design operators and among the latter and the information exchanged: the Building Objects. Its primary research goal is thus the conceptual structure of the building organism for the purpose of managing conflicts and developing possible methods of resolving them.

title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.

summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title Integrating Design Tools within a Human Collaborative Working Context
source International Journal of Construction IT, Vol5, No 2, pp 35-53
summary Integrating design tools has been an important research subject. The work to be reported in this paper differs from many previous efforts in that it not only tackles tool-tool interoperation, but also does so within a human collaborative working context We suggest that design integration support should include not only tool interoperability, but also mechanisms for co-ordinate and control the tool use. We also argue that the higher-level management support should include not only formalised and automated mechanisms, but also semi-automated and even informal mechanisms for human designers to directly interact with each other. Within a collaborative working framework, we'll present a hybrid architecture for tool integration, in which the human designers and the design tools are assumed to be distributed while the management is centralised. In this approach, each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A meta-data augmented product model, which populates a central meta-data repository serving as a "map" for locating the distributed design objects, is devised to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. A design object broker is used to mediate among the distributed tools, and the central meta-data repository. The reported work has been part of a collaborative design system called virtual studio environment We'll illustrate how the integrated design tools might be used in human design work within the virtual studio environment.

title Architecture in Landscape: Integrated CAD Environments for Contextually Situated Design
doi https://doi.org/10.52842/conf.ecaade.1997.x.q6p
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary This paper explores the future role of a more holistic and integrated approach to the design of architecture in landscape. Many of the design exploration and presentation techniques presently used by particular design professions do not lend themselves to an inherently collaborative design strategy.

Within contemporary digital environments, there are increasing opportunities to explore and evaluate design proposals which integrate both architectural and landscape aspects. The production of integrated design solutions exploring buildings and their surrounding context is now possible through the design development of shared 3-D and 4-D virtual environments, in which buildings no longer float in space.

The scope of landscape design has expanded through the application of techniques such as GIS allowing interpretations that include social, economic and environmental dimensions. In architecture, for example, object-oriented CAD environments now make it feasible to integrate conventional modelling techniques with analytical evaluations such as energy calculations and lighting simulations. These were all ambitions of architects and landscape designers in the 70s when computer power restricted the successful implementation of these ideas. Instead, the commercial trend at that time moved towards isolated specialist design tools in particular areas. Prior to recent innovations in computing, the closely related disciplines of architecture and landscape have been separated through the unnecessary development, in our view, of their own symbolic representations, and the subsequent computer applications. This has led to an unnatural separation between what were once closely related disciplines.

Significant increases in the performance of computers are now making it possible to move on from symbolic representations towards more contextual and meaningful representations. For example, the application of realistic materials textures to CAD-generated building models can then be linked to energy calculations using the chosen materials. It is now possible for a tree to look like a tree, to have leaves and even to be botanicaly identifiable. The building and landscape can be rendered from a common database of digital samples taken from the real world. The complete model may be viewed in a more meaningful way either through stills or animation, or better still, through a total simulation of the lifecycle of the design proposal. The model may also be used to explore environmental/energy considerations and changes in the balance between the building and its context most immediately through the growth simulation of vegetation but also as part of a larger planning model.

The Internet has a key role to play in facilitating this emerging collaborative design process. Design professionals are now able via the net to work on a shared model and to explore and test designs through the development of VRML, JAVA, whiteboarding and video conferencing. The end product may potentially be something that can be more easily viewed by the client/user. The ideas presented in this paper form the basis for the development of a dual course in landscape and architecture. This will create new teaching opportunities for exploring the design of buildings and sites through the shared development of a common computer model.

title Visualizing Information: Internet Guidelines for Distributing Architectural Research
source Virginia Polytechnic Institute and State University
summary A web site was designed and constructed for the Research + Demonstration Facility (RDF) as a masters thesis project to help educators teach future architects more interactively by using the dynamic medium of the Internet. Students and faculty will learn about evolving architectural research and technology as well as potential consequences of design decisions. Educators will be able to conduct online research, or tele-experiments, in the classroom thus allowing students to learn, in near real-time, the outcome or progress of research on and off campus. This project presents some of the possibilities of how the Internet can enhance re-search information delivery to students and faculty of architecture.

title Executable Drawings: The Computation of Digital Architecture
doi https://doi.org/10.52842/conf.acadia.1998.172

summary Architectural designs are principally represented by drawings. Usually, each drawing corresponds to one design or aspects of one design. On the other hand, one executable drawing corresponds to a set of designs. These drawings are the same as conventional drawings except that they have computer code or programs embedded in them. A specific design is the result of the computer executing the code in a drawing for a particular set of parameter values. If the parameters are changed, a new design or design variation is produced. With executable drawings, a CAD system is also a program editor. A designer not only designs by drawing but also programming. It fuses two activities: the first, drawing, is basic in architectural practice; and the second, progamming, or specifying the relation of outputs from inputs, is basic in computer system development. A consequence of executable drawings is that architectural form is represented by graphical entities (lines or shapes) as well as computer code or programs. This type of architecture we call digital architecture. Two simple examples are presented: first, the design of a building in terms of an executable drawing of the architects, Sangallo the Younger and Michelangelo, and second, a description of an object oriented implementation of a preliminary prototype of an executable drawing system written in 1997 which computes a simple office layout.
