title A Data Model Analysis of Modularity and Extensibility in Building Databases
source Building and Environment, Vol 27, No: 2, pp. 135-148
summary This paper uses data modeling techniques to define how database schemas for an intelligent integrated architectural CAD system can be made extensible. It reviews the product data modeling language EDM, then applies it to define a part of an architectural data model. Extensions are then investigated, regarding how users could integrate various design-specific packages into a uniquely configured system. Both, extension by substituting one technology for another and by adding a new evaluation application, are considered. Data modeling allows specification of a CAD database and identification of the kind of modularization that will work and what problems may arise.''

title On the Limitations of Shape Grammars: Comments on Aaron Fleisher’s Article “Grammatical Architecture?”
doi https://doi.org/10.52842/conf.acadia.2003.279
source Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 279-287
summary Shape grammars were introduced by Gips and Stiny in 1972. Since then, there have been many articles and books written by them and their associates. In 1992, Aaron Fleisher, a professor at the School of Planning, MIT, wrote a critique of their work in an article titled “Grammatical Architecture?” published in the journal Environment and Planning B. According to him, Gips, Stiny and later Mitchell, propose a hypothesis that states that shape grammars are presumed to represent knowledge of architectural form, that grammars are “formable,” and that there is a visual correspondence to verbal grammar. The strong version of “the hypothesis requires that an architectural form be equivalent to a grammar.” Fleisher considers these hypotheses unsustainable, and argues his case by analyzing the differences between language, and architecture, and by dealing with the concepts of lexicons, syntax and semantics. He concludes by stating that architectural design is negotiated in two modalities: the verbal and the visual, and that equivalences are not at issue; they do not exist. If there is such thing as a language for design, it would provide the means to maintain a discussion of the consequences in one mode, of the state and conditions of the other. Fleisher’s observations serve as the basis of this paper, a tribute to him, and also an opportunity to present an outline to an alternate approach or hypothesis to shape grammars, which is “nonlinguistic” but “generative,” in the sense that it uses production rules. A basic aspect of this hypothesis is that the only similarity between syntactic rules in language and some rules in architecture is that they are recursive.

title Spatial Perception in Virtual Environments : Evaluating an Architectural Application
source University of Washington
summary Over the last several years, professionals from many different fields have come to the Human Interface Technology Laboratory (H.I.T.L) to discover and learn about virtual environments. In general, they are impressed by their experiences and express the tremendous potential the tool has in their respective fields. But the potentials are always projected far in the future, and the tool remains just a concept. This is justifiable because the quality of the visual experience is so much less than what people are used to seeing; high definition television, breathtaking special cinematographic effects and photorealistic computer renderings. Instead, the models in virtual environments are very simple looking; they are made of small spaces, filled with simple or abstract looking objects of little color distinctions as seen through displays of noticeably low resolution and at an update rate which leaves much to be desired. Clearly, for most applications, the requirements of precision have not been met yet with virtual interfaces as they exist today. However, there are a few domains where the relatively low level of the technology could be perfectly appropriate. In general, these are applications which require that the information be presented in symbolic or representational form. Having studied architecture, I knew that there are moments during the early part of the design process when conceptual decisions are made which require precisely the simple and representative nature available in existing virtual environments. This was a marvelous discovery for me because I had found a viable use for virtual environments which could be immediately beneficial to architecture, my shared area of interest. It would be further beneficial to architecture in that the virtual interface equipment I would be evaluating at the H.I.T.L. happens to be relatively less expensive and more practical than other configurations such as the "Walkthrough" at the University of North Carolina. The set-up at the H.I.T.L. could be easily introduced into architectural firms because it takes up very little physical room (150 square feet) and it does not require expensive and space taking hardware devices (such as the treadmill device for simulating walking). Now that the potential for using virtual environments in this architectural application is clear, it becomes important to verify that this tool succeeds in accurately representing space as intended. The purpose of this study is to verify that the perception of spaces is the same, in both simulated and real environment. It is hoped that the findings of this study will guide and accelerate the process by which the technology makes its way into the field of architecture.

title Mission Possible: Computer Aided Design for Everyone
doi https://doi.org/10.52842/conf.acadia.1992.065

summary A pragmatic model for the building of an electronic architectural design curriculum which will offer students and faculty the opportunity to fully integrate information age technologies into the educational experience is becoming increasingly desirable.

The majority of architectural programs teach technology topics through content specific courses which appear as an educational sequence within the curriculum. These technology topics have traditionally included structural design, environmental systems, and construction materials and methods. Likewise, that course model has been broadly applied to the teaching of computer aided design, which is identified as a technology topic. Computer technology has resulted in a proliferation of courses which similarly introduce the student to computer graphic and design systems through a traditional course structure.

Inevitably, competition for priority arises within the curriculum, introducing the potential risk that otherwise valuable courses and/or course content will be replaced by the "'newer" technology, and providing fertile ground for faculty and administrative resistance to computerization as traditional courses are pushed aside or seem threatened.

An alternative view is that computer technology is not a "topic", but rather the medium for creating a design (and studio) environment for informed decision making.... deciding what it is we should build. Such a viewpoint urges the development of a curricular structure, through which the impact of computer technology may be understood as that medium for design decision making, as the initial step in addressing the current and future needs of architectural education.

One example of such a program currently in place at the College of Architecture and Planning, Ball State University takes an approach which overlays, like a transparent tissue, the computer aided design content (or a computer emphasis) onto the primary curriculum.

With the exception of a general introductory course at the freshman level, computer instruction and content issues may be addressed effectively within existing studio courses. The level of operational and conceptual proficiency achieved by the student, within an electronic design studio, makes the electronic design environment selfsustaining and maintainable across the entire curriculum. The ability to broadly apply computer aided design to the educational experience can be independent of the availability of many specialized computer aided design faculty.

title INTELLIGENT KNOWLEDGE-BASED REPOSITORY TO SUPPORT INFORMED DESIGN DECISION MAKING
source ITCON journal
summary Research highlights that architectural design is a social phenomenon that is underpinned by critical analysis of design precedents and the social interaction between designers including negotiation, collaboration and communication. CAAD systems are continuously developing as essential design tools in formulating and developing ideas. Researchers such as (Rosenman, Gero and Oxman 1992) have suggested suggest that knowledge based systems can be integrated with CAAD systems to provide design knowledge that would enable recalling design precedents that maybe linked to the design constraints. Currently CAAD systems are user centric being focused on architects rather than the end product. The systems provide limited assistance in the production of innovative design. Furthermore, the attention of the designers of knowledge based systems is providing a repository rather than a system that is capable to initiate innovation. Most of the CAAD systems have web communication tools that enable designers to communicate their design ideas with colleagues and partners in business. However, none of these systems have the capability to capture useful knowledge from the design negotiations. Students of the third to fifth year at College of Architecture, University of Dammam were surveyed and interviewed to find out how far design tools, communications and resources would impact the production of innovative design projects. The survey results show that knowledge extracted from design negotiations would impact the innovative design outcome. It highlights also that present design precedents are not very helpful and design negotiations between students, tutors and other students are not documented thus fully incorporated into the design scheme. The paper argues that the future CAAD systems should be capable to recognize innovative design precedents, and incorporate knowledge that is resulted from design negotiations. This would help students to gain a critical mass of knowledge that would underpin informed design decisions.

title Open-source, parametric architecture to propagate hyper-dense, sustainable urban communities: parametric urban dwellings for the experience economy
doi https://doi.org/10.52842/conf.caadria.2010.443
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 443-452
summary Rapid developments in societal, technological, and natural systems suggest profound changes ahead if research in panarchical systems (Holling, 2001) is to be believed. Panarchy suggests that systems, both natural and man-made, rise to the point of vulnerability then fail due to disruptive forces in a process of ‘creative destruction.’ This sequence allows for radical, and often unpredictable, renewal. Pressing sustainability concerns, burgeoning urban growth, and emergent ‘green manufacturing’ laws, suggest that future urban dwellings are headed toward Gladwell’s ‘tipping point’ (2002). Hyper-dense, sustainable, urban communities that employ open-source standards, parametric software, and web-based configurators are the new frontier for venerable visions. Open-source standards will permit the design, manufacture, and sale of highly diverse, inter-operable components to create compact urban living environments that are technologically sophisticated, sustainable, and mobile. These mass-customised dwellings, akin to branded consumer goods, will address previous shortcomings for prefabricated, mobile dwellings by stimulating consumer desire in ways that extend the arguments of both Joseph Pine (1992) and Anna Klingman (2007). Arguments presented by authors Makimoto and Manners (1997) – which assert that the adoption of digital and mobile technologies will create large-scale societal shifts – will be extended with several solutions proposed.

source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 195-200
summary The appropriate use of spatial simulation techniques considerably tends to increase the depth of evidence and the realistic content of the design and plannings to be described and moreover may encourage experimentations, trial attempts and planning variants. This means also the more frequent use of combinations between different techniques, having in mind that they are not equivalent, but making use of the respective advantages each offers. Until now the main attention of the EDP-Lab was directed on achieving quantity. For the time to come time it will be the formation of quality. The challenge in the educational system at the Vienna University of Technology is to obtain appropriate results in the frame- work of low-cost simulation. This aspect seems also to be meaningful in order to enforce the final implementation in architectural practice.

title An Approach to 3D Conceptual Modelling
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary This article presents a 3D user interface required by the development of conceptual modeling. This 3D user interface provides a new structure for solving the problems of difficult interface operations and complicated commands due to the application of CAD 2D interface for controlling 3D environment. The 3D user interface integrates the controlling actions of “seeing – moving –seeing” while designers are operating CAD (Schön and Wiggins, 1992). Simple gestures are used to control the operations instead. The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis. The study aims to discuss the provision of more intuitively interactive control through CAD so as to fulfil the needs of designers. In our practices and experiments, a pair of LED gloves equipped with two CCD cameras for capturing is used to sense the motions of hands and positions in 3D. In addition, circuit design is applied to convert the motions of hands including selecting, browsing, zoom in / zoom out and rotating to LED switches in different colours so as to identify images.

title A FRAMEWORK FOR COMPUTER-SUPPORTED COLLABORATION IN ARCHITECTURAL DESIGN
source University of Michigan
summary The development of appropriate research frameworks and guidelines for the construction of software aids in the area of architectural design can lead to a better understanding of designing and computer support for designing (Gero and Maher 1997). The field of research and development in computer-supported collaborative architectural design reflects that of the early period in the development of the field of computersupported cooperative work (CSCW). In the early 1990s, the field of CSCW relied on unsystematic attempts to generate software that increases the productivity of people working together (Robinson 1992). Furthermore, a shift is taking place by which researchers in the field of architecture are increasingly becoming consumers of rather than innovators of technology (Gero and Maher . In particular, the field of architecture is rapidly becoming dependent on commercial software implementations that are slow to respond to new research or to user demands. Additionally, these commercial systems force a particular view of the domain they serve and as such might hinder rather than help its development. The aim of this dissertation is to provide information to architects and others to help them build their own tools or, at a minimum, be critical of commercial solutions.

title CONTEXTUALIZATION AND EMBODIMENT IN CYBERSPACE
doi https://doi.org/10.52842/conf.caadria.2004.005
source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 5-14
summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

title Computers and architectural design: going beyond the tool
source Automation in Construction 9 (1) (2000) pp. 5-17
summary More often than not, discussions taking place in specialised conferences dealing with computers and design tend to focus mostly on the tool itself. What the computer can do that other tools cannot, how computers might improve design and whether a new aesthetic would result from the computer; these are among the most recurrent issues addressed in those forums. But, by placing the instrument at the center of the debate, we might be distorting the nature of design. In the course KEYWORDS, carried out in the years 1992 and 1993 at the ETH Zurich, the goal was to transcend the discourses that concentrate on the computer, integrating it in a wider theoretical framework including principles of modern art and architecture. This paper presents a summary of the content and results of this course.

summary The multi-level, multidimensional nature of architecture means that the only way to experience it and evaluate it is by moving within the buildings and the environment they constitute. Until today, architectural projects could only be observed after they had been finished. The recently developed environmental simulator is the solution to the problem. With the simulator and scale models we can observe the experience of moving around within the buildings and thus make a significant improvement in the certainty of the assumed architectural experience and content while the project is still under design.

source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 251-264
summary The scope of this paper is to present Computer Aided Architectural Design (and more particularly the dynamic and incremental modeling characteristics of Object Based Modeling) as a tool to reinforce the teaching of architectural design. Utilized within a method based on a cyclical application of "Concept and Testing", OBM has the possibility to work as an amplifier of design ideas and as a meaningful tool for the advancement of architectural design. Three related experiences support this hypothesis. The role played in concrete designs by an Object Based Modeling environment. Teaching with CAAD and OBM in the realm of documentation and analysis of architecture. Previous applications of the Concept-Testing methodology in design studios. The central sections of the paper focus on the analysis of these experiences, while the last section provides a 15 week, semester based, studio structure that incorporates OBM in the overall calendar and in key assignments. While the scope of this work coincides with the thesis presented at the Acadia '92 conference in Charleston (South Carolina), to focus the argument more clearly content, text and illustrations differ in several parts.

title The visual harmony between new and old materials in the restoration of historical architecture: A study of computer simulation
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

summary In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

summary As well as learning traditional design techniques, students in architecture courses learn how to use powerful workstations with CAD systems, color scanners and laser printers and software for the rendering, compositing and animating of their designs.

They learn to use raytracing and radiosity rendering systems to provide visual realism, alpha-channel compositing systems to put a client in the picture (literally) or the design in situ, and keyframe animation systems to allow realistic walkthroughs.

Student Presentations are now based on videos, photographic slides, slide shows or real time animation. Images (as data files) are imported into full color publishing systems for final year thesis presentation.

The architectural graphics environment at Curtin University facilitates the integration of slide and video examples of raytraced and chroma-keyed images with computer aided design techniques for architectural student presentations.

title Using conceptual modelling and an object-oriented environment to support building cost control during early design
source College of Architecture and Urban Planning, University of Michigan
summary This research investigated formal information modelling techniques and the object-oriented knowledge representation on the domain of building cost control during early design stages. The findings contribute to an understanding of the advantages and disadvantages of applying formal modelling techniques to the analysis of architectural problems and the representation of domain knowledge in an object-oriented environment. In this study, information modelling techniques were reviewed, formal information analysis was performed, a conceptual model based on the cost control problem domain was created, a computational model based on the object-oriented approach was developed, a mechanism to support information broadcasting for representing interrelationships was implemented, and an object-oriented cost analysis system for early design (OBCIS) was demonstrated. The conceptual model, based on the elemental proposition analysis of NIAM, supports a formal approach for analyzing the problem domain; the analysis results are represented by high-level graphical notations, based on the AEC Building System Model, to visually display the information framework of the domain. The conceptual model provides an intermediate step between the system designer's view of the domain and the internal representation of the implementation platform. The object-oriented representation provides extensive data modelling abilities to help system designers intuitively represent the semantics of the problem domain. The object-oriented representation also supports more structured and integrated modules than conventional programming approaches. Although there are many advantages to applying this technique to represent the semantics of cost control knowledge, there are several issues which need to be considered: no single satisfactory classification method can be directly applied; object-oriented systems are difficult to learn; and designing reusable classes is difficult. The dependency graph and information broadcasting implemented in this research is an attempt to represent the interrelationships between domain objects. The mechanism allows users to explicitly define the interrelationships, based on semantic requirements, among domain objects. In the conventional approach, these relationships are directly interpreted by system designers and intertwined into the programming code. There are several issues which need to be studied further: indirect dependency relationship, conflict resolution, and request-update looping based on least-commitment approach.

title Maximising the Benefits of CAD Systems in Architectural Education
doi https://doi.org/10.52842/conf.ecaade.1994.x.u8n

summary The positive impact of Computer Aided Design (CAD) in professional architectural practice has been in focus in recent times but relatively little has been written on its significance in the education of the contemporary architect. It is common knowledge that the profession of architecture is currently undergoing enormous strains as it battles to keep abreast of trends and developments in a period of series of rapid advancement in science, technology and management (RIBA, 1992). Whilst attempts are being made to redress the shortcomings of the profession in the above context, the requirements for architectural education are yet to forge a coherent strategy for the implementation of CAD/IT in the curriculum of schools of architecture. In almost every other field, including engineering, medicine and the humanities, computing application to problem-solving and decision-making is seen as a way forward as we move into 21st century. Architectural education must integrate CAD/IT into the teaching of core modules that give the architect distinctive competence: studio design. That is one of the best ways of doing justice to the education of the architect of today and the future. Some approaches to the teaching of CAD in schools of architecture have been touched upon in the recent past. Building upon this background as well as an understanding of the nature of design teaching/learning, this paper examines ways of maximising the benefits of CAD systems in architectural education and of bringing computer aided designing into the studio not only to enhance design thinking and creativity but also to support interactive processes. In order to maximise or optimise any function, one approach is to use the hard systems methodology which utilises analytic, analogic and iconic models to show the effect of those factors which are significant for the purposes being considered. The other approach is to use the soft systems methodology in which the analysis encompasses the concept of a human activity system as a means of improving a situation. The use of soft systems methodology is considered more appropriate for dealing with the problem of design which is characterised by a flux of interacting events and ideas that unroll through time. The paper concludes that the main impediment to maximising the benefits of CAD systems in architectural education is not only the inappropriate definition of the objectives for the implementation of CAD education but also that the control subsystems are usually ill-structured and relatively poorly defined. Schools must attempt to define a coherent and consistent policy on the use of CAD systems as an integral part of studio design and evolve an in-house strategic and operational controls that enable the set objectives to be met. Furthermore, it is necessary to support the high level of productivity from CAD systems with a more efficient management system, especially in dealing with communication, data sharing via relational database, co-ordination and integration. Finally, the use of soft systems methodology is recommended as the way forward to optimising CAD systems in design education as it would provide continuous improvements while maintaining their productive value.
