title	An experience on supporting the learning of technical graphics and improving visualization
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This paper presents an experience of applying computer graphics, virtual reality and Internet resources in the teaching of technical graphics in engineering and design courses at the University of Brasilia, Brazil. Our motivation was the fact that most of the students have a lack of previous knowledge on the basis of drawings, resulting difficulties in both understanding and visualizing technical drawings. As an experimental method, we introduced VRML 3D modeling in addition to CAD and regular pencil-and-paper drawings study and practice. To better support learning, we first provided a website with animations and virtual reality resources, avoiding the usual textbook metaphor. Since 2003 we are providing a CD-ROM containing all the former website material which is updated each semester. This experience is intended to improve the learning in a way that motivates the students. Classes, website and CD-ROM material was conceived to take advantage of computers´ interactivity and animated resources.

title	New Generation of Computer Aided Design In Space Planning Methods - a Survey and A Proposal
doi	https://doi.org/10.52842/conf.caadria.2003.101
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 101-116
summary	During the past thirty years, the progress of ComputerAided Design (CAD) has played an important role both in the professional and the academic fields of architectural design. The evolution of this powerful tool has also changed its direction with time as well. When we look back in the evolution history of CAD, spaceplanning allocation methods, which have been discussed and developed vigorously during the 1970s, became less so after that. Space planning is a critical issue during the architectural design process on which architects spend a large amount of time on early development. This paper will review the space-planning methods during that period and discuss the possibilities of improving these methods, and extending their potential in current computer-aided design methods.

title	Sustainability: real and/or virtual?
source	Automation in Construction, 12(6), November 2003, pp. 641–648
summary	The starting point for this paper is the identification of the four necessary and sufficient conditions which a building should exhibit to be judged to be sustainable; fitness-for-purpose, cost effectiveness, environmental friendliness, and cultural significance. The contribution which the current generation of CAD tools is making to the complex human activity of designing sustainable buildings is then discussed under the headings of widening the search for solutions, integrating the decision-making process, improving design insights, differentiating objective/subjective issues and photorealistic visualization. The paper then describes developments in the next generation of IT tools, based on virtual reality, which will allow multiple designers, working in distributed locations and on different computer platforms, to design from within the virtual world.

title	Experimental Tools for the Teaching of Technical Graphics and Improving Visualization
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 457-468
summary	This paper presents an updated evaluation of an experience of applying computer graphics, virtual reality and Internet resources in the teaching of technical graphics at the University of Brasilia, Brazil. It differs from a previous paper (Pratini, 2004) for the addition of an overview of the course, the context and the new teaching methodology. It is an extended, more detailed paper, which includes examples, and closes with some results of surveys on the didactic material and the methodology. Our motivation for this experiment is the fact that most of the students have a lack of previous knowledge on the basis of drawings, resulting difficulties in both understanding and visualizing technical drawings. In this experiment, we introduced VRML 3D modeling in addition to CAD and regular pencil-and-paper drawings study and practice. To support the learning of this broad knowledge not present in the technical graphics bibliography, we first provided a website with animations and virtual reality resources. Since 2003 we are providing a CD-ROM containing all the former website material which is updated each semester. At the present time, the CD-ROM contains almost all the needed didactic material and software for the one semester technical graphics course. This experience was intended to improve and to support learning in a way that motivates the students, young people who are used to play video and computer games. Classes, website and CD-ROM material were conceived to take advantage of computers´ interactivity and animated resources. The use of computers´ technology and new media to support the learning resulted a new methodology and several new unanswered questions.

title	Discussing Image-Based Modeling Technology for 3D Digital Archival of Physical Architecture Models
doi	https://doi.org/10.52842/conf.ecaade.2003.373
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 373-380
summary	Besides drawings, physical models are important forms of representation commonly used for architectural design. They can serve as a useful resource for teaching and research, provided there is a proper archiving system that allows easy retrieval. Architectural models in 3D digital format seem to be able to overcome the limitation of physical constraints – they can be easily accessed anytime and anywhere over the Internet. The most common way of 3D model documentation is through geometric-based 3D CAD software. Image-based modeling (IM) allows the 3D digital model to be created from photographic images. Debevec (1998) investigated the hybrid geometry- and image-based approach whilst Tsou (2002) and Hawkins (2001) focused on the application of IM for GIS and digitizing cultural artifacts respectively. This paper aims to compare physical models and their IM counterparts in terms of communication of vital architectural information. Experiments were conducted to evaluate the extent the IM model resembled the physical predecessor in terms of its geometry and visual appearance qualities/faithfulness. A survey was subsequently carried out to compare their performance in terms of the communication of vital architectural information about building designs to the observers. The tabulated results were then examined to help understand the opportunities and weakness of IM for 3D archival of physical architecture models

summary	Modelling of interoperable and extensible design information is one of the key issues in computer-aided architectural design. IFC technology provides standardised mechanisms for the development of such information models. By using the IFC dynamic definition extension mechanism this paper presents a method for IFC-compliant design information modelling for architectural CAD objects. The method has been implemented as an addon toolkit to the Architectural Desktop CAD package. The use scenarios of the toolkit are discussed in the paper for CAD property modelling, property database management, and interoperable design information modelling with property set extensions.

title	The pattern of Internet use for information management by architectural practices in the UK
source	Cardiff University, Welsh School of Architecture Cardiff, UK
summary	In recent history, architects have experienced problems related to the use and management of new innovations. The Internet presents one such challenge. It offers considerable expansion in types of communication and sources of business information and connects people and businesses around the globe. As is argued in this research, these services could play a positive role in architectural practice. This research examines the use of the Internet by architectural practices in UK in order to reveal how aware they are of the opportunities it presents, the extent to which they are taking advantage of them, and the problems they are experiencing. A field study was conducted of two types of practices: RIBA private practices and local authority practices. A number of research tools were used to inspect how these practices are using the Internet to manage various types of information that used and produced in the practice, namely: the acquisition of web information, the exchange of the practice’s information through the web and the presentation of the practice’s information on the web. Explanations for the results were sought by correlating variables from the questionnaire study, using simple statistical tests. The field study shows that many Internet services are unpopular among architects, and that practices have problems in adopting and using the technology. The pace at which the Internet is being absorbed and accepted by practices is slow. The study suggests that possible causes are: the little knowledge of users’ about IT, the poor resources of the practice, and old or imperfect Internet installations and the absence of the Internet support to the architect’s activities. The research argues that there are a number of links between these negative factors which make the practice unable to utilize the Internet and to manage the practice’s information through the Internet. To break these links, the research suggests that practices should adopt a specific management strategy to promote more utilization of Internet services in the office and to manage information. Practices need to make certain changes to the way they manage the Internet and work with it, if they plan to integrate the Internet more successfully into their practice. The research discusses techniques for improving practice management which would help practices to digest Internet technology and to use it more effectively in the practice.

title	IMPROVING NEURAL NETWORK MODELS OF PHYSICAL SYSTEMS THROUGH DIMENSIONAL ANALYSIS
source	Journal of Applied Soft Computing 2(4): 283-296.
summary	The paper presents a technique for generating concise neural network models of physical systems. The neural network models are generated through a two-stage process. The first stage uses information embedded in the dimensions or units in which the data is represented. Dimensional analysis techniques are used initially to make this information explicit, and a limited search in the neural network architecture space is then conducted to determine dimensionless representations of variables/parameters that perform well for a given model complexity. The second stage uses information available in the numerical values of the data to search for high-level dimensionless variables/parameters, generated from simple combinations of dimensionless quantities generated in the first stage and which result in concise neural network models with improved performance characteristics. The search for these high-level dimensionless variables/parameters is conducted in an enhanced representation space using functional link networks with flat or near flat architectures. The use and effectiveness of the technique is demonstrated for three applications. The first is the design and analysis of reinforced concrete beams, which is representative of the class of problems associated with the design and analysis of composites. The second is the classical elastica problem, for predicting non-linear post-buckled behaviour of columns and the third, the analysis of a bent bar under a specified combination of loads.

title	SpaceScope: Spatial Content-Based Retrieval of Architectural Floor Plans
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 53-62
summary	This research investigates spatial information retrieval in architecture, based on an efficient metadata that is crucial for content-based retrieval. SpaceCore is the metadata schema for spatial information on a floor plan implemented with RDF (Resource Description Framework). To generate metadata, we analyse the factors of spatial information, and then construct a data model containing the content and structure of spatial information. To exploit the metadata, we suggest various query operations with possible predicates and interfaces. SpaceScope, the spatial information retrieval system, consists of three modules: an input data module, a query module, and a browse module. As to implementation, we have already developed the real time plan-structuring system, called “Vitruvius”, as an inputting and modelling data module (using C++). Based on the database, the system performs the similarity analysis and then evaluates the alternative plans with the retrieval goals. At the end of the paper we discuss the potential of SpaceScope in the schematic design stage of the architectural design process, possibly improving and triggering the designer’s conceptual approach against a logical background and facilitate rapid decision-making after full consideration.

doi	https://doi.org/10.52842/conf.acadia.2003.179
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. 179-183
summary	The real estate and construction industry is among the largest industries in the world. It also is one of the most fragmented industries, with few economies of scale and historically low productivity. Recent technological advances in the use of information and communication technology have the potential for dramatically improving construction productivity. But substantial organizational barriers exist that inhibit the effective adoption of these technologies. This research project (in progress) examines the practices of selected, innovative firms in order to develop an in-depth understanding of the factors that have influenced the effective adoption of information and communications technology in the design and construction industry, and, potentially, provide examples that may provide prototype models for an alternative, future organization of the AEC industry.

title	Case Study of Tacit Knowledge Sharing in a Distributed Design Studio
doi	https://doi.org/10.52842/conf.acadia.2003.107
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. 107-116
summary	This paper demonstrates the effects of experts’ tacit knowledge on improving architectural students’ design artifacts in a distributed design studio. In geographically distributed design environments, the Internet is an important medium by which architects can share tacit knowledge in the form of dialogue via online communication technologies, such as online chat and Instant Messaging (IM). In spring 2003, the National Aeronautics and Space Administration (NASA) and 8 schools conducted a collaborative design studio to develop a crew restraint system for space flights. Online chat software was used as a primary communication channel. Throughout the entire design studio, NASA professionals served as knowledge holders while undergraduate students participated as knowledge seekers. An interpretive content analysis and case study methodology were used in this study. We qualitatively observed the interactions between NASA and the students based upon two aspects: knowledge reflection and design improvement. Data were collected using document analysis of all knowledge sources and students’ design artifacts. The findings of this study indicate that the online chat system is useful in sharing tacit knowledge for the early part of design processes in a distributed design environment. Experts’ tacit knowledge appears to not only influence how students understand problems, but how they initiate conceptual design. This study provides empirical evidence regarding tacit knowledge sharing, and strengthens Schon’s (1983) claim about knowledge reflection in design studio. Furthermore, this study introduces architectural practitioners to the practical necessity of tacit knowledge sharing. This study is significant because its findings indicate the appropriate knowledge management strategy for architectural practitioners.

summary	Globalisation and international competition force the AEC industry to change its work and collaboration practices. The traditional way of working is evolving into a more integrated process, and the traditional use of “synchronised passive” files and paperbased communication is being replaced with ICT based solutions. Currently, the AEC community is at an intermediate stage, i.e., it is shifting to “online” electronic documents. In this paper, a new concept called “eDocument” (eDoc) is introduced. The eDoc project is a cooperative effort in order to develop and implement a generic dynamically structured, multimedia, multi-channel, and multimodal information system as a means for communication in AEC projects. The major innovation in the concept is that, although it uses a repository, the focus is on the “logical and physical” specifications of the eDoc concept as a shared tele-workspace that is accessible through multiple platforms

summary	CAD tools are increasing their expressive and geometric power to enable a design process in which the computer model can be used throughout the whole design process for realizing the design. Such a process, in which other media such as physical scale models or drawings are no longer required by necessity to facilitate the design process, can be considered a digital design process. Rather than proposing that such a process is ideal – drawings and scale models should not be discarded – we feel that when taken as a starting point, the digital design process raises a number of new challenges to architectural design that deserve attention. These challenges concern the basic activities in design: exploration of the problem space, creating preliminary solutions, understanding consequences of design decisions, and so forth. In this paper we take the concrete design case of a graduation project that was developed from the start solely in CAD. We identify a number of key issues in that process such as continuous modeling, the model as design, continuous pliability, localized focus, and postponed decision. These issues not only have a technical, CAD-related aspect, but also are connected to architectural design. Most of these aspects are subject of contemporary debate in architectural design. On this basis, we can indicate where CAD is making a potential difference in architectural design.

title	A Critical Evaluation of Early Stages Software in its Capacity of Coping with Contextual Issues
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	In this paper we analyse critically early design stages software in its capacity of coping with contextual data at large (i.e. representing cultural, aesthetical context, etc.). We identified 5 categories of early stages software: geometry based graphic editors, evaluation architectural software, generative and shape-grammar based systems, evolutionary systems and other systems. Calling the object under creation during of the early stages a CAD conceptual model, we will investigate to what extend this software allows the architect to experience and represent the context in which a design is situated. Especially we will focus on its capacity to allow interaction, playful interaction on our way to the design. Designers, and particularly architects, interact with the local context similarly to interacting in a game: the context influences the users’ decisions, surprises them and causes permanent changes to their ways of thinking. On the other hand, architects permanently shape and reshape the context, and reduce the context to a protean point of reference. Such behaviour characterises creative thinking that is crucial for the early stage of design. The investigation led us to the conclusions that the effective interactivity with the context needs simple rules, a plain interface and data reduced as simple as possible, especially when interaction with the context is performed during the early stages of a design process. The findings can be used in organising computer environments for early-stage design.

summary	This paper presents a constraint-based modeling system, integrated into a widely used CAD modeler. Using a notification mechanism, the system records the precision functions called by the user in order to maintain geometric relations between points locations and source objects. These relations are stored in a directed graph which allows an automatic update of the model.

title	Information Spaces for Mobile City Access
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	This paper describes two complementary European research projects that share common interests and goals.The work described is intended to facilitate city analysis and support decision-making. The first project focuses on the distribution, access and ease of use of city data. The system allows access to historical data concerning key buildings in Liverpool, England, via a suite of web-based tools and a palmtop device. The second project looks at extending the functionality of traditional computer aided design (CAD) software to enable geometric and semantic data to be combined within a single environment. The system allows those involved in city planning to better understand the past and present development pattern of an area so that their decisions on future proposals are better informed.The paper concludes by describing a system that integrates particular aspects of the two projects, and the potential that this integration can bring.This new work provides mobile access to historical city development data, current city information and tools to support urban project development.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	Safety is an important element of project successes. In the conventional project management, safety planning, as a function, is separated from other functions, such as planning/scheduling function. This separation creates difficulties for engineers to analyze what, when, why and where a safety measure is needed to prevent accidents in a construction activity. Another problem occurs due to the conventional practice of representing project designs using two-dimensional (2D) drawings. In this practice, a user (e.g. an engineer) has to convert the 2D drawings into three-dimensional (3D) mental pictures, and this is a tedious task. If only converting this 2D drawing is a tedious task, combining these 2D drawings with safety planning creates more difficult tasks. In order to address the problems, this paper discusses our research in integrating construction scheduling and safety planning in a 4D environment.

title	Architecture as a Reference for the Development of A Cad Lighting Tool
doi	https://doi.org/10.52842/conf.caadria.2003.281

summary	As light is increasingly perceived as a factor of quality of urban life, it is not surprising that cultural heritage buildings and even civil engineering works are being more and more often illuminated at night. The designers of the projects are revealing a nocturnal vision of the buildings which is often a reflection of the architecture: rhythm, pattern, evenness, symmetry, composition, axes, and so on. The idea of developing a "lighting-modeller" is based upon this assertion. Thus, if we express the needs in terms of functionalities, we can conclude that the hierarchical structure of the architectural edifice can fit in with a "lighting-structure". As a result, concepts like hierarchy, linking, grouping, networking, linearity-polarity, are the basis of the objects and functions that are effective for the great majority of buildings and projects. This "lighting-modeller" can then lead beyond its simulation capabilities to become a design conception tool: hypothesis and variants are quickly realized and tested, and technical data (illumination data, visual comfort) can be obtained as well.
