title	Design Tool Integration: Model Flexibility for the Building Profession
source	Proceedings of Building Systems Automation - Integration, University of Wisconsin-Madison
summary	The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by simulation tools, can be used to converse with knowledge-based systems. We consider the types of mappings that occur in the often different views of a building held by these two classes of design tools. This leads us to examine the need for multiple views of a common building model. We then extend our analysis from the views required by simulation and knowledge-based systems, to those required by different segments of the building profession (e.g. architects, engineers, developers, etc.) to converse with such an integrated system. This indicates a need to provide a flexible method of accessing data in the common building model to facilitate use by different building professionals with varying specialities and levels of expertise.

title	An integrated system to aid the planning of concrete structures: introducing the system
source	The Int. Journal of Construction IT1(2), pp.1-14
summary	This paper reports on the development at Loughborough University of a CAD-based integrated model to aid the planning of in-situ concrete structures. The system development started after a review of the planning models currently available and after a detailed questionnaire survey undertaken amongst the top UK and US contractors on the current status of planning techniques and information technology. The main aim of this system is to automate the planning process of in-situ concrete structures using data generated by CAD systems. So far, the integration of a CAD system (AutoCAD 10) and a computerized scheduling system (Artemis 2000) has been achieved on a typical IBM-PC. This enables the generation of network plans using AutoCAD which are then automatically transferred to the Artemis system for time and cost analyses.Traditionally, construction planners are faced with many conventional drawings and documents which are used to re-extract information relevant to their planning processes. Such an approach can be very inefficient as it involves data double-handling and is often error prone. In addition, current computerized construction planning applications are little more than the automation of manual formulations of plans. For example, data are fed into the planning system and computations are performed using either CPM (Critical Path Method) or PERT (Programme Evaluation and Review Technique). However, data relating to the planning process such as activity lists, resources requirements and durations are not automatically generated within the system. It would thus seem logical to devise a CAD-based integrated planning model which accepts data in its electronic format and involves some integration of the traditional planning approach. This paper introduces the proposed CAD-based integrated planning model and describes its different components. In addition, it discusses the system functional specifications and summarizes the main benefits and limitations of such a model.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

summary	Beginning in 1993, small groups of students of architectural design at different institutions around the world participated in collaborative design projects using a variety of tools, including CAD, Internet and teleconferencing. This programme, known as the "Virtual Design Studio" (VDS), allows students to work collectively with colleagues from different cultures and climates who are thousands of kilometres and in different time zones. Most recently, in February 1994, four institutions in N. America, one in Europe, and one in S E Asia participated in VDS’94. This paper explains the operation of the VDS and explores the future of the VDS as a potential tool for architectural design education. In particular, we review what we have learned in employing computer tools to extend the teaching in design studios into a "virtual" experience.

title	The Evolution of an Interface for Choreographers Evolving Design
source	Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems 1993 pp. 115-122
summary	This paper describes the evolution of the interface to Life Forms, a compositional tool for the creation of dance choreography, and highlights some of the important lessons we have learned during a six year design and implementation period. The lessons learned can be grouped into two categories: 1) Process, and 2) Architecture of the Interface. Our goal in developing a tool for choreography has been to provide computer-based creative design support for the conception and development of dance. The evolution was driven by feedback from the choreographers and users who were members of the development team, combined with our knowledge of current thinking on design and composition. Although the interface evolved in a relatively unconstrained way, the resulting system has many of the features that theoretical discussion in human interface design has projected as necessary. The Life Forms interface has evolved incrementally with one major discontinuity where adoption of a new compositional primitive required a completely new version. The choreography and composition of a dance is a complex synthesis task which has much in common with design. Thus, the lessons learned here are applicable to the development of interfaces to such applications as computer aided design.

title	SOME EPISTEMOLOGICAL CONCERNS REGARDING ARTIFICIAL INTELLIGENCE AND KNOWLEDGE-BASED APPROACHES TO ARCHITECTURAL DESIGN - A RENEWED AGENDA
doi	https://doi.org/10.52842/conf.acadia.1993.155
source	Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 155-162
summary	It has been noted that designers - when confronted with computers - have, by and large, refused to accept the introduction of apparently new design methodologies, and it has been speculated that this is the result of a failure of those methodologies to address the cognitive processes which take place in the course of designing. This position is somewhat suspect in that such innovations as computer-aided drafting -which also fail to recognize these processes have been widely accepted. It is perhaps more likely that the lack of acceptance results from a perception on the part of designers that the new methodologies either do not reflect some or all of those concerns that designers consider fundamental to design, or that they actively interfere with the designer's ability to accomplish what he/she sees as the goals of design. Given that the application of artificial intelligence and related work to architecture is still in its infancy, all of this suggests the need for a reassessment of the role of computing in design in order to clarify and strengthen those roles deemed appropriate. Two approaches to the integration of artificial intelligence and knowledge-based systems into architectural design practice are currently dominant. One attempts to create systems which can on their own produce designs, the other provides intelligent support for those doing design. It was, in part, the recognition of limitations in the ability of traditional CAD systems and building modelers to reflect what designers actually do that led to explorations into the idea of intelligent assistants. Development of such assistants was aided by research into the act and process of design through protocol and other studies. Although some work is currently being done in the development of artificial intelligence and knowledge based applications in architecture, and work continues to be done on the study of design methodologies, the bulk of available information in each of these areas remains in the realm of design disciplines related to but outside of architecture and do not reflect the explicit role of architectural design in the embodiment and expression of culture. The relationship of intelligence to culture has resulted in some skepticism regarding the ultimate capacity of neural nets and symbolically programmed computers in general. Significant work has been done questioning the rational tradition in computer development for its failure to address phenomena which are not easily subject to scientific analysis. Further skepticism regarding the role of artificial intelligence and knowledge-based or expert systems in architectural design has been emerging recently. Such criticism tends to focus on two issues: the nature of drawing as an activity which involves both the generation and interpretation of graphic artifacts, and the nature of the human designer as an active agent in the design process.

title	Computer aided design: back to the drawing board
source	Proc. of Creativity and Cognition, Loughborough, April
summary	This paper argues that the role of Computer Aided Design (CAD) should be to enhance and extend paper-based working, rather than to replace it. Current CAD tools are little used in the early stages of designing. Paper is heavily used, with its physical properties supporting work practices that are not possible with CAD. This paper presents implications for the design of new computer-based tools drawn from observations of designers' work practices. A new system is described that integrates paper-based and computer-based working in the same physical space and supports the application of computation to images on paper.

title	Hybrid Design Environments - A Research Program on Creative Collaboration and Communication
doi	https://doi.org/10.52842/conf.ecaade.1993.x.a8h
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	This paper gives an overview of a research program initiated in the Architectural Design Department of the Escola Tècnica Superior d'Arquitectura de Barcelona on issues of communication and collaboration in computer aided design. The work is centered around emerging design situations which can be attributed directly to the incorporation of new technologies in education and practice. One of these is the "design triangle" composed of a traditional designer, a CAD workstation and a computer literate collaborator acting as the design medium. Another is the "virtual workshop" consisting of design collaboration involving large-scale distributed communications networks. The research program stresses three common characteristics of these situations which it aims to study in parallel in the setting of an design workshop. The first of these is the characteristic of distance, both physical and conceptual, which separates, on the one hand, the traditional designer from the CAD document and, on the other, the participants of a distributed workshop from each other and each others' thinking. The second, is the typically hybrid nature of such situations where computer technology interacts with more traditional techniques and alternative media are combined both at the level of production and in channels and modes of communication. And finally, the third and most significant for the methodology of the research program, is the fact that both the design triangle and the virtual workshop make explicit aspects of design activity, interaction and intentions which remain hidden or are only implicit in traditional designing.

title	Modelling effects of cad on concrete construction using production graphs
source	The Int. Journal of Construction IT 1(4), pp. 39-50
summary	Quantitative statements on effects of CAD systems are needed to manage their use in concrete construction, but are hard to make. This paper describes an approach to model the effects of CAD systems on concrete construction. The approach is based on the concept of 'the market value of information commodities', and uses graph theory to build a formal model of the construction process. The formal model, so-called production graph, allows for investigation and quantification of the effects of CAD systems, which depend on their so-called value adding dimensions. An example of application of the approach is provided. Experiences with this approach are very good. General patterns between the value adding dimensions of CAD systems and their effects on production graphs must be determined to develop a descriptive and predictive model. Case-studies are being done to identify these general patterns.

title	Exploring Structural Morphology Using CAD
doi	https://doi.org/10.52842/conf.ecaade.1993.x.d1k
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Often in the design process the student's imagination is restricted by their inability to visualise, model or accurately sketch ideas for innovative structural systems. By using CAD as a design tool it is possible to explore the morphology of complex structures and to be able to produce perspective drawings of them with relative ease. Within AutoCAD there is a small library of standard three-dimensional objects and surfaces that can be called upon to generate more complex forms. However, to further facilitate the architectural design process, an extended library of innovative structural forms would allow the professional designer, or student, greater design freedom and any increase in the palette of structural forms available should stimulate creativity. As practical examples, the paper describes how students have been encouraged to experiment with the use of structures which can only be physically modelled with difficulty and which are also difficult to represent on the two- dimensional surface of the drawing board unless the geometry has previously been determined by the methods described. These are (i) Reciprocal Frame three-dimensional beam grillage structures and (ii) plate domes created from lattice structures by point-to- plane duality. The problem, of representation of these structures has been overcome, in the first case, by generating AutoLISP procedures to draw the complex three-dimensional geometrical form automatically in AutoCAD and, in the second case, by the development of the computer program CADual.

summary	This paper demonstrates the approach to Architectural education that has been developed over the last 3 years on the MSc Computing & Design course at the University of East London. Although the course deals exclusively in computer based topics, the main concern is primarily with developing a design methodology and a way of teaching design method, more particularly an algorithmic description of form. Rule based design, emergent form and bottom up approaches to design have become fashionable to the point of ubiquity in the last 5 years, but we like to think that only at UEL have these concerns been linked to a consistent view of design.

title	Understanding the AR-VR Based Architectural Design Workflow among Selected Danish Architecture Practices
doi	https://doi.org/10.52842/conf.ecaade.2022.1.381

summary	Virtual reality (VR) and augmented reality (AR) have been proposed to be additional architectural design mediums for at least 25 years (Dagit, 1993). Despite rapid technical and technological development, it has not been adopted into architectural design practices as compared to academia and research. Surveys from the American Institute of Architects (AIA) and Royal Institutes of British Architects (RIBA) demonstrate the state of architectural practices; 72% of architects and 65% of architects respectively are not using any kind of virtual, augmented, or mixed reality in their practices(RIBA and Microsoft, 2018; Hampson, 2020). In this paper, the authors investigate the state of practices, issues, challenges, and opportunities of the utilization of virtual, augmented, and mixed realities in six architectural practices in the Danish context. Three of the practices are large architectural practices, one medium-sized practice specializing in institutional, healthcare and cultural architecture, and one firm designing private family houses, kindergartens, daycares and places for people with disability and, one experimental design studio. All these practices have used VR/AR in their projects to various degrees. In recent years Danish architectural practices have been involved in various VR/AR-based exhibitions, demonstrations, and tool developments to promote the usage of the same in design practice. Through a set of qualitative interviews with personnel from key architectural practices, the authors would like to demonstrate the present state of practices. The investigation explores the usage of VR and AR in Danish architecture practices by identifying challenges and opportunities regarding skill levels, architectural typology, use cases, toolchains, and workflow and shows similarities and differences between traditional and VR-based design processes. The main findings show how VR/AR-based visualization helps architects to perceive spatiality and also ushers creativity through immersion and overlays.

summary	The boundaries of augmented reality in the academic field are now being explored at an ever increasing level. In this paper we present the initial findings of an educational project focusing on the use of augmented reality in the design process of an architectural student. The study seeks to evaluate the use of AR as a tool in the design stages, allowing effective exploration of spatial qualities of design projects undertaken in the studio. The learning process is guided by the exploration and detection of a design idea in both form and function, with the virtual environment providing a dynamic environment (Mantovani, 2001). This is further reflected in the constructivist theory where the learning processes use conceptual models, which are used to create incremental stages that become the platform to attain the next [Winn, 1993]. The additional benefit of augmented reality within the learning journey is the ability of the students to visually explore the architectural forms they are creating in greater depth.

summary	This paper is part of the research on Generative Design and is inspired by the ideas spread by the following paradigms: the Internet of Things (Auto-ID Center, 1999) and the Pervasive/Ubiquitous Computing (Weiser, 1993). Particularly, the research describes a number of case studies and, in detail, the experimental prototype of an interactive-design object: “Grow-1”. The general assumptions of the study are as follows: a) Developing the experimental prototype of a smart-design object (Figure 1) in terms of interaction with man, with regard to the specific conditions of the indoor environment as well as in relation to the internet/web platforms. b) Setting up a project research based on the principles of Generative Design.c) Formulating and adopting a methodology where computational design techniques and interactive prototyping ones converge, in line with the principles spread by the new paradigms like the Internet of Things.

summary	Abstract as well as functionally dependant design exercises are essential components of an architectural education at nearly every university. Their goal is to provide architect students with a feeling for proportions, colours, materials etc., and to teach and train them in threedimensional thinking. Pictures and concepts, developed by the designer are materialized by various technologies such as with pencil and paper in the traditional two-dimensional techniques or with clay, wood, paper etc. in three-dimensional modeling. Now the computer and the CAD-system join the palette of the designers available resources in presentation as both a two-dimensional and a three-dimensional medium. Although CAD is often considered and taught to be only a better drafting tool, the educational goal of our group at the University of Dortmund is to employ CAD as a design support medium. The prerequisites for work with the computer and the CAD system are provided in a compulsory two semester undergraduate subject. Basic programming, work with spreadsheets etc. are some exemplary themes provided in the form of lectures and practical exercises. A main emphasis of this instruction is the mastery of three-dimensional working technology with a comprehensive CAD-System. In cooperation of our computer science group and architecture chairs, seminars involving the use of CAD as a three-dimensional design tool, are offered as graduate courses. The seminars consist of loops of modeling and evaluating objects in a three-dimensional space. With this, the most possible realistic studies in colour, light and proportion take place exclusively on the computer.

title	Common Illumination between Real and Computer Generated Scenes
source	Proceedings Graphics Interface '93, pp. 254-262, 1993
summary	The ability to merge a real video image (RVI) with a computer- generated image (CGI) enhances the usefulness of both. To go beyond "cut and paste" and chroma-keying, and merge the two images successfully, one must solve the problems of common viewing parameters, common visibility and common illumination. The result can be dubbed Computer Augmented Reality (CAR). We present in this paper techniques for approximating the common global illumination for RVIs and CGIs, assuming some elements of the scene geometry of the real world and common viewing parameters are known. Since the real image is a projection of the exact solution for the global illumination in the real world (done by nature), we approximate the global illumination of the merged image by making the RVI part of the solution to the common global illumination computation. The objects in the real scene are replaced by few boxes covering them; the image intensity of the RVI is used as the initial surface radiosity of the visible part of the boxes; the surface reflectance of the boxes is approximated by subtracting an estimate of the illuminant intensity based on the concept of ambient light; finally global illumination using a classic radiosity computation is used to render the surface of the CGIs with respect to their new environment and for calculating the amount of image intensity correction needed for surfaces of the real image. An example animation testing these techniques has been produced. Most of the geometric problems have been solved in a relatively ad hoc manner. The viewing parameters were extracted by interactive matching of the synthetic scene with the RVIs. The visibility is determined by the relative position of the "blocks" representing the real objects and the computer generated objects, and a moving computer generated light has been inserted. The results of the merging are encouraging, and would be effective for many applications.

summary	The development and implementation of a modular building model appropriate for computer aided design is described. The limitations of a unified building model with regard to concurrence and complexity in design is discussed. Current research suggests that to model real-world complexity, one must trade centralized control for autonomy. In this paper we develop a modular approach to building modelling that is based on object-oriented autonomy and makes it possible to define these models in a distributed concurrent manner. Such a modular and autonomous implementation brings inherent uncertainty and conflict which cannot be determined a priori.
