title	Designing with Words and Pictures in a Logic Modelling Environment

summary	At EdCAAD we are interested in design as something people do. Designed artefacts, the products of designing, are interesting only in so far as they tell us something about design. An extreme expression of this position is to say that the world of design is the thoughts in the heads of designers, plus the skills of designers in externalizing their thoughts; design artifacts, once perceived and accepted in the worlds of other people, are no longer part of the world of design. We can describe design, briefly, as a process of synthesis. Design has to achieve a fusion between parts to create new parts, so that the products are recognized, as having a right and proper place in the world of people. Parts should be understood as referring to anything - physical objects, abstract ideas, aspirations. These parts occur in some design environment from which parts are extracted, designed upon and results replaced; in the example of buildings, the environment is people and results have to be judged by reference to that environment. It is characteristic of design that both the process and the product are not subject to explicit and complete criteria. This view of design differs sharply from the more orthodox understanding of scientific and technological endeavours which rely predominantly on a process of analysis. In the latter case, the approach is to decompose a problem into parts until individual parts are recognized as being amenable to known operations and results are reassembled into a solution. This process has a peripheral role in design when evaluating selected aspects of tentative design proposals, but the absence of well-defined and widely recognized criteria for design excludes it from the main stream of analytical developments.

title	Representing the Structure of Design Problems
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 158-170
summary	In recent years several experimental CAD systems have emerged which, focus specifically on the structure of design problems rather than on solution generation or appraisal (Sussman and Steele, 1980; McCallum, 1982). However, the development of these systems has been hampered by the lack of an adequate theoretical basis. There is little or no argument as to what the statements comprising these models actually mean, or on the types of operations that should be provided. This chapter describes an attempt to develop a semantically adequate basis for a model of the structure of design problems and presents a representation of this model in formal logic.

title	Three-dimensional Input and Visualization
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 68-84
summary	The aim of this chapter is to investigate techniques by which man-computer interaction could be improved, specifically in the context of architectural applications of CAD. In this application the object being designed is often an assembly of defined components. Even if the building is not actually fabricated from such components, it is usually conceptualized in these terms. In a conventional graphics- based CAD system these components are usually represented by graphical icons which are displayed on the graphics screen and arranged by the user. The system described here consists of three- dimensional modelling elements which the user physically assembles to form his design. Unlike conventional architectural models which are static (i.e. cannot be changed by the users) and passive (i.e. cannot be read by a CAD system), this model is both 'user generated' and 'machine readable'. The user can create, edit and view the model by simple, natural modelling activities and without the need to learn complex operating commands often associated with CAD systems. In particular, the user can view the model, altering his viewpoint and focus of attention in a completely natural way. Conventional computer graphics within an associated CAD system are used to represent the detailed geometry which the different three-dimensional icons may represent. In addition, computer graphics are also used to present the output of the performance attributes of the objects being modelled. In the architectural application described in this chapter an energy- balance evaluation is displayed for a building designed using the modelling device. While this system is not intended to offer a completely free-form input facility it can be considered to be a specialist man-machine interface of particular relevance to architects or engineers.

summary	In order to discuss this question it is necessary to reflect awhile on design methods in general. The usual categorization discusses 'generations' of design methods, but Levy (1981) proposes an alternative approach. He identifies five paradigm shifts during the course of the twentieth century which have influenced design methods debate. The first paradigm shift was achieved by 1920, when concern with industrial arts could be seen to have replaced concern with craftsmanship. The second shift, occurring in the early 1930s, resulted in the conception of a design profession. The third happened in the 1950s, when the design methods debate emerged; the fourth took place around 1970 and saw the establishment of 'design research'. Now, in the 1980s, we are going through the fifth paradigm shift, associated with the adoption of a holistic approach to design theory and with the emergence of the concept of design ideology. A major point in Levy's paper was the observation that most of these paradigm shifts were associated with radical social reforms or political upheavals. For instance, we may associate concern about public participation with the 1970s shift and the possible use (or misuse) of knowledge, information and power with the 1980s shift. What has emerged, however, from the work of colleagues engaged since the 1970s in attempting to underpin the practice of design with a coherent body of design theory is increasing evidence of the fundamental nature of a person's engagement with the design activity. This includes evidence of the existence of two distinctive modes of thought, one of which can be described as cognitive modelling and the other which can be described as rational thinking. Cognitive modelling is imagining, seeing in the mind's eye. Rational thinking is linguistic thinking, engaging in a form of internal debate. Cognitive modelling is externalized through action, and through the construction of external representations, especially drawings. Rational thinking is externalized through verbal language and, more formally, through mathematical and scientific notations. Cognitive modelling is analogic, presentational, holistic, integrative and based upon pattern recognition and pattern manipulation. Rational thinking is digital, sequential, analytical, explicatory and based upon categorization and logical inference. There is some relationship between the evidence for two distinctive modes of thought and the evidence of specialization in cerebral hemispheres (Cross, 1984). Design methods have tended to focus upon the rational aspects of design and have, therefore, neglected the cognitive aspects. By recognizing that there are peculiar 'designerly' ways of thinking combining both types of thought process used to perceive, construct and comprehend design representations mentally and then transform them into an external manifestation current work in design theory is promising at last to have some relevance to design practice.

title	An Overview of Knowledge Engineering and its Relevance to CAAD
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 107-119
summary	Computer-aided architectural design (CAAD) has come to mean a number of often disparate activities. These can be placed into one of two categories: using the computer as a drafting and, to a lesser extent, modelling system; and using it as a design medium. The distinction between the two categories is often blurred. Using the computer as a drafting and modelling tool relies on computing notions concerned with representing objects and structures numerically and with ideas of computer programs as procedural algorithms. Similar notions underly the use of computers as a design medium. We shall return to these later. Clearly, all computer programs contain knowledge, whether methodological knowledge about processes or knowledge about structural relationships in models or databases. However, this knowledge is so intertwined with the procedural representation within the program that it can no longer be seen or found. Architecture is concerned with much more than numerical descriptions of buildings. It is concerned with concepts, ideas, judgement and experience. All these appear to be outside the realm of traditional computing. Yet architects discoursing use models of buildings largely unrelated to either numerical descriptions or procedural representations. They make use of knowledge - about objects, events and processes - and make nonprocedural (declarative) statements that can only be described symbolically. The limits of traditional computing are the limits of traditional computer-aided design systems, namely, that it is unable directly to represent and manipulate declarative, nonalgorithmic, knowledge or to perform symbolic reasoning. Developments in artificial intelligence have opened up ways of increasing the applicability of computers by acquiring and representing knowledge in computable forms. These approaches supplement rather than supplant existing uses of computers. They begin to allow the explicit representations of human knowledge. The remainder of this chapter provides a brief introduction to this field and describes, through applications, its relevance to computer- aided architectural design.

title	Modelling Design Descriptions
source	January, 1986. [5] p. : ill
summary	This paper reports some of the principles that underlie a modelling environment being developed at EdCAAD. It describes research that is part of a larger programme directed at computer-based systems that can accommodate the idiosyncratic nature of design practice, without prescriptions to the form or content of designs. That is, towards developing systems to assist in the design process by enabling designers -via conversations with the machine - to make 'reasonable' statements about design objects; to ask 'reasonable' questions about these objects; and to perform 'reasonable' tasks on these objects. Implicit in the authors' approach is the view that designing is an activity dependent on designers' perceptions of design tasks and their resolution. In the context of computer-aided design, this view of design demands that the crucial element in any machine environment lies in the ability of the machine to accept (partial) descriptions of design objects. Moreover, these descriptions can be manipulated according to some (perhaps unanticipated) criteria that the designer may wish to apply. The authors present a model for intentional descriptions of objects. That is, a description that can be structures so that it can be used to recognize objects and can be compared with other descriptions. Such a description of an object should be organized around entities with associated descriptions, it must be able to represent partial knowledge about an object, and it must accommodate multiple descriptors which can describe the object from different viewpoints. Last, but not least, these descriptions should possess a quality of 'truth' in that they reflect the (factual or otherwise) beliefs held by the designer. One way to treat these descriptions is to regard them as statements that belong to some logical framework

title	Teaching CAAD at Sheffield University
source	Teaching and Research Experience with CAAD [4th eCAADe Conference Proceedings] Rome (Italy) 11-13 September 1986, pp. 78-87
doi	https://doi.org/10.52842/conf.ecaade.1986.078
summary	The University of Sheffield Department of Architecture has been using Computer Aided Architectural Design in its teaching now for over ten years. During that time there has also been a major research unit in CAAD working in the department and most of the software used in our teaching programme has originated in our own research unit. Our students have now got access to a wide range of CAAD programs including 2D draughting, 3D colour visualisation, environmental analysis, structural design and cost estimating. We have generated our own specialised systems of terrain modelling and intelligent building modelling which link to both the visualisation and environmental appraisal software. Students also have access to data base and word processing software. CAAD has been used in all five years of our course and we also have students working .with CAAD during their professional experience years. Over this ten year period we have gradually altered and refined our approach to the educational use of CAAD and this paper will describe this approach and present some of the lessons we have learnt. I want to organise the paper into two main sections; firstly what are we trying to achieve by teaching CAAD on our course, and secondly, how do we fit this into the curriculum and what effect does it have.

title	Three-dimensional Visualization: A Case Study
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 92-102
summary	Three-dimensional computer visualization has intrigued both building designers and computer scientists for decades. Research and conference papers present an extensive list of existing and potential uses for threedimensional geometric data for the building industry (Baer et al., 1979). Early studies on visualization include urban planning (Rogers, 1980), treeshading simulation (Schiler and Greenberg, 1980), sun studies (Anon, 1984), finite element analysis (Proulx, 1983), and facade texture rendering (Nizzolese, 1980). With the advent of better interfaces, faster computer processing speeds and better application packages, there had been interest on the part of both researchers and practitioners in three-dimensional -models for energy analysis (Pittman and Greenberg, 1980), modelling with transparencies (Hebert, 1982), super-realistic rendering (Greenberg, 1984), visual impact (Bridges, 1983), interference clash checking (Trickett, 1980), and complex object visualization (Haward, 1984). The Division of Building Research is currently investigating the application of geometric modelling in the building delivery process using sophisticated software (Evans, 1985). The first stage of the project (Vanier, 1985), a feasibility study, deals with the aesthetics of the mode. It identifies two significant requirements for geometric modelling systems: the need for a comprehensive data structure and the requirement for realistic accuracies and tolerances. This chapter presents the results of the second phase of this geometric modelling project, which is the construction of 'working' and 'presentation' models for a building.

title	Computer Aided Dimensional Control in Building Construction
source	Eindhoven University of Technology
summary	Dimensional control in the building industry can be defined as the operational techniques and activities that are necessary, during the construction process of a building, for the assurance of the defined dimension quality of a building (Hoof, 1986). Efficient and precise dimensional control of buildings under construction is becoming ever more important because of changes in the construction industry. More prefabricated components are used; more regulations appear; newly designed buildings have more complex shapes, and building construction is speeding up. To ensure the predefined dimensional quality, a plan of dimensional control must be designed, on the basis of building drawings and specifications delivered by architects, before the building is constructed. The dimensional control plan must provide site personnel with adequate information on, among others, setting out and assembling building components, which can often be done by means of Total Stations. The essence of designing a dimensional control plan is to find out which points should be used as positioning points, which points should be set out in advance or controlled afterwards, and not to forget why. In an effort to contribute to the improvement of the dimensional control of on-site construction projects, this research tries to capture the knowledge required to design an adequate dimensional control plan and make that knowledge more generally available, and build a digital connection between CAD systems and Total Stations, focusing on prefabricated concrete building structural elements. The instrument developed in this research for capturing of essential dimensional control information and knowledge makes use of Product Data Technology (PDT) and Knowledge Technology (KT). The chosen solution supports the stochastic analysis of optimal positioning points taking account of various sorts of deviations and their mutual relationships. The resulting information model has been written in a standardized information modelling language called UML (Unified Modelling Language). The model has been implemented in a Dimensional Control System (DCS) and applied in the “La Tour” construction project in Apeldoorn, the Netherlands. The DCS provides a digital way to bridge the floor plan design with dimensional control, predict dimensional deviation limits and output the data needed for a Total Station. The case study of “La Tour” tests the UML model and prototype of the DCS. The results prove that direct positioning of objects (by putting reflectors on the objects and using a Total Station and by inputting coordinates extracted and calculated from the AutoCAD drawings) provides higher speed, accuracy and reliability. It also shows a way to (pre)position free form objects in 3D where traditional methods cannot. In conclusion: (1) it seems to be justified to expect that the application of the DCS will contribute to increased confidence in dimensional control and the reduction of costs of failure, which potentially could support the increased use of cheaper construction methods, and will also contribute to the improvement of building design and construction process. (2) the scientific contribution of this research is a first step towards providing dimensional quality in a construction process covered by stochastic dimensional uncertainty, even for positioning of free form objects.

title	The Role of Expert Systems Technology In Design
source	[2] 49 p. : diagrams Engineering Design Research Center, CMU, September, 1986 EDRC-06-13-86. includes bibliography.
summary	Using a scenario format, this paper first reviews the nature of chemical process design, showing that designers quickly make major decisions with minimal information and constantly revise their strategy to solve a problem. To automate this activity on a computer will require models of the process being created at several levels of abstraction as well as models that capture the beliefs of the modeler about the abilities of himself, others and the aids available and models of strategies for complex problem solving. The second section of the paper extensively reviews current expert system concepts, illustrating each of them with design examples. It is argued that expert systems are knowledge based. The authors describe many of the control strategies used in today's systems, and also consider different problem representations - rules, logic and frames - and indicate when each might be preferred. The last section presents the authors views on what will be involved in creating a future expert system for design

doi	https://doi.org/10.52842/conf.ecaade.1986.136
summary	This paper describes a modelling system, MOLE (Modelling Objects with Logic Expressions), and its use as a computing environment for teaching architectural undergraduates. The paper also sketches the background to MOLE's development as a medium for research, and identifies benefits conferred on research and teaching through their common interest in MOLE. Teaching at EdCAAD is conducted in what is chiefly a research milieu. Hence our teaching methods exploit the products and experience of research. But the partnership is mutually rewarding, because teaching informs future research efforts through the experience gained from using MOLE. At present, our teaching concentrates on a ten-week elective course for fourth year architectural undergraduates. The main component of the course requires each student to program a simple application related to architectural design. Applications normally require a programming language with access to graphics routines, and in previous years we have used C or, more recently, Prolog with their graphics extensions. For the past two years MOLE has fulfilled this need. The paper begins by explaining the evolution of our approach to CAAD, leading to the development of the description system, MOLE. Section two outlines the main features of the version of MOLE which has been extended to provide a comprehensive computing environment for programming simple architectural applications. MOLE in use is the subject of section three which is illustrated with examples drawn from students' coursework projects and exercises. This is followed by a discussion of the lessons learned from teaching which highlight areas of MOLE's development that need more study. A concluding section summarises what has been learned, and poses vital questions that require answers before we can expect widespread acceptance of CAAD in practice.

summary	It is now vital to aim at formulating computer system modules that possess a high ability to adapt their behavior to fundamental human values and a complex and unstandardized (not uniform) building process but at the same time put constraints on them so that we don't end up with a confusion of computerized routines hard to access, control and understand. In the paper formulations are made of basic artifact skeletons outgoing from the properties to give integrated CAD systems and to those rules by which the growth of the systems are governed. System learning domains including conceptual modelling tools are presented aiming at supporting professional skill, creativity and integration between process actors. The basis for system implementation is frames, descriptive language (PROLOG) and relational databases with regard taken to future possibilities to parallel processing

title	VEGA : A Geometric Modelling System
source	11 p. : ill. Engineering Design Research Center, CMU, April 1986. DRC-48-03-87. includes bibliography
summary	VEGA is a program which models rigid solid objects in three dimensions. Specifically, its domain is assemblies of planar faced polyhedra. VEGA supports a variety of operations to create, modify, query and delete these assemblies. VEGA is intended to serve two purposes: that of a new medium of representation for the design process; and of a programming package to support geometric applications in a wide variety of domains. Here the author addresses primarily the first of these purposes, that of a new medium for design. Designers of physical objects use an external medium, traditionally paper or physical models, not only to record their work, but to provide information which assists in the understanding of implications of design decisions. Designers proceed by performing operations, which reflect internal design decisions, on this external medium. The operations used in design are generally reflective of these physical media. For example, models built of clay tend to be formed by a subtractive processes, whereas models built of wood tend to be additive in nature. Designers who use drawings as their medium still tend to use operations which reflect operations on physical models. Computers provide the fascinating potential to provide a much wider variety of operations at a much greater speed than is available with the traditional means of representation. In addition, a computer based representation can provide quantitative information not easily accessible from traditional forms. This opens the potential for the inclusion of formal means of evaluation in the design process; something which is generally almost absent in traditional design teaching. A computer program which effectively and 'naturally' models physical objects and operations on them would be a valuable assistance to both the teaching and practice design. VEGA has been designed with these objectives in mind. VEGA represents physical objects with a scheme known as boundary representation and provides a wide variety of operations on these objects. VEGA also provides means to associate other, non-geometric, information with the objects it represents. VEGA is implemented under the ANDREW system. It communicates to ANDREW through a graphics package, also developed by the author's group. VEGA is intended to serve as a medium for future studio courses in the Architecture, Industrial Design and Arts education

title	CAD and Management of Construction Projects
source	Journal of Construction Engineering and Management, Vol. 112, December, pp. 557-565
summary	The increasing interest in computer-aided design (CAD) has prompted research that is aimed at identifying the opportunities for construction managers and building contractors. It has been found that the use of CAD systems in the U.K. is mainly confined to the production of detailed drawings. Indeed, most of the systems used are 2-D drafting tools and incapable of supporting the integration of even modest amounts of nongraphical (construction) data. On the other hand, many 3-D modeling systems have the potential to integrate construction data, although they appear to be almostignored. The use of 3-D modeling systems is considered to be the most suitable vehicle for successfully integrating these data. However, this is likely to necessitate the introduction of separate databases, preferably of the relational type. The use of 3-D modeling systems in assessing the construction implications of outline designs also presents interesting possibilities and is discussed.

doi	https://doi.org/10.52842/conf.ecaade.1986.167
summary	Any applied research, no matter what discipline is concerned, needs affined and suitable tools; as regards the studies in the field of architecture and planning, the use of automatic systems of analysis, data ordering and comparison is of particular interest. The quickness of operations by means of computers and the corresponding graphical representation gives new possibilities for scientific work, once impossible, not certainly because of conceptual limits, but practically, for the limits of available tools. It is the wideness of applications of computers to be pointed out, for although studied for scientific reasons, their practical usefulness is often enormous. This has been generally verified. It guilts in particular for the CAD System, proposed and explained in this paper. The practical utility this and other systems from the same field have for the public administration, contractors and consultants is well known and therefore not necessary to be described further. The use of such systems is particularly convenient in those sectors where the graphical representation is the basic part of the production process.

summary	Context awareness is important for human senses of places as well as human computer interaction. The aim of this research paper is focusing on controlling the user's privacy in a smart space which is adaptive to different users for enhancing the user's awareness in his diary life. In Environmental Psychology, the definition of privacy is that an individual has the control of deciding what information of himself is released to others, and under how he interact with others. (Westin 1970) And privacy is categorized as the linguistic privacy and visual privacy. (Sundstorm 1986). Solutions for privacy control: Plan Layout, Vision Boundary, Access Control and Architecture Metaphor - the transmission of information is not ascertainable for every single user. Although information are shown in public, but information is implied by cues and symbols. Only a certain user or a group of users have access to the full context of information. The methodology is to form an analytic framework to study the relationship between information, user and activities by using the computational supports derived from KitchenSense, ConceptNet, Python, 3d Studio Max and Flash; and to record patterns built up by users' behaviour and actions. Furthermore, the scenario-based simulation can envision the real world conditions by adding interfaces for enhancing user awareness.

summary	The problems of architectural education in general and CAD education in particular are discussed. The paper suggests that the computing requirements of architectural practice are different to those of architectural education and that much of the software used in schools of architecture is not used in an educationally structured way. A number of proposals for the educational use of computers are made, together with recommendations for a common computing environment.

summary	The paper describes a new procedure of design management and the results of its application to architectural design in an exercise developed in a didactic context. The procedure requires the participation of all “actors” (i.e. designers, experts, clients, users, etc.) involved in the design process and which contribute, directly or indirectly, to obtain the result. By generating and developing alternative design solutions, this procedure allows the exploration of a region of the performances space which is generally more vast than that explored by the traditional designer.

summary	The design process requires continual checking of the consistency of design choices against given sets of goals that have been fulfilled. Such a check is generally performed by comparing abstract representations of design goals with these of the sought real building objects (RBO) resulting from complex intellectual activities closely related to the designer's culture and to the environment in which he operates. In this chapter we define a possible formalization of such representations concerning the goals and the RBO that are usually considered in the architectural design process by our culture in our environment. The representation of design goals is performed by expressing their objective aspects (requirements) and by defining their allowable values (performance specifications). The resulting system of requirements defines the set of allowable solutions and infers an abstract representation of the sought building objects (BO) that consists of the set of characteristics (attributes and relations) which are considered relevant to represent the particular kind of RBO with respect to the consistency check with design goals. The values related to such characteristics define the performances of the RBO while their set establishes its behaviour. Generally speaking, there is no single real object corresponding to an abstract representation but the whole class of the RBO that are equivalent with respect to the values assumed by the considered characteristics. The more we increase the number of these, as well as their specifications, the smaller the class becomes until it coincides with a single real object - given that the assessed specifications be fully consistent. On the other hand, the corresponding representation evolves to the total prefiguration of the RBO. It is not therefore possible to completely define a BO representation in advance since this is inferred by the considered goals and is itself a result of the design process. What can only be established in advance is that any set of characteristics assumed to represent any RBO consists of hierarchic, topological, geometrical and functional relations among the parts of the object at any level of aggregation (from components to space units, to building units, to the whole building) that we define representation structure (RS). Consequently the RS may be thought as the elementary structures that, by superposition and interaction, set up the abstract representation that best fit with design goals.

summary	Creativity is always interested in many fields, in particular, creativity and design creativity have many interpretations (Boden, 1991; Gero and Maher, 1992, 1993; Kim, 1990; Sternberg, 1988; Weisberg, 1986). In early conceptual design process, designers used large number of sketches and drawings (Purcell and Gero, 1998). The sketch can inspire the designer to increase the creativity of the designer’s creations(Schenk, 1991; Goldschmidt, 1994; Suwa and Tversky, 1997). The freehand sketches by conventional media have been believed to play important roles in processes of the creative design thinking(Goldschmidt, 1991; Schon and Wiggins, 1992; Goel, 1995; Suwa et al., 2000; Verstijnen et al., 1998; Elsas van and Vergeest, 1998). Recently, there are many researches on inspiration of the design creativity by digital media(Liu, 2001; Sasada, 1999). The digital media have been used to apply the creative activities and that caused the occurrenssce of unexpected discovery in early design processes(Gero and Maher, 1993; Mitchell, 1993; Schmitt, 1994; Gero, 1996, 2000; Coyne and Subrahmanian, 1993; Boden, 1998; Huang, 2001; Chen, 2001; Manolya et al. 1998; Verstijinen et al., 1998; Lynn, 2001). In addition, there are many applications by combination of conventional and digital media in the sketches conceptual process. However, previous works only discussed that the individual media were related to the design creativity. The cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent.
