summary	Generative design methods are capable of generating concepts and stimulating solutions based on robust and rigorous models of design conditions, design languages and design performance. The computer now becomes a design generator in addition to its more conventional role as draftsperson, visualizor, data checker and performance analyst. Motivated by the challenge to enable designers to easily develop meaningful input models of design intent to make best use of a structural generative method, this paper describes an initial combination of a generative design tool, eifForm, and an associative modeling system, Custom Objects, through the use of XML models. The current combined use is illustrated through an example involving generation of a set of 20 interrelated roof trusses with seven unique spans initiated by a parametric model of a saddle shaped stadium roof in Custom Objects. The paper concludes with a discussion of the synergies between associative modeling and generative systems and identifies future extensions aimed to exploit these synergies towards integrated performance-based generative design tools.

title	Persistence of Perception: Encoding Reality
source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	"Liquid architecture makes liquid cities, cities that change at the shift of value, where visitors with different backgrounds see different landmarks, where neighborhoods vary with ideas held in common, and evolve as the ideas mature or dissolve." In 1991, Marcos Novak in 'Liquid Architectures in Cyberspace' projected a future of individual and blended realities of things perceived and perceived things - a place of "fertile dreams". In the cathedral, "The dream and making were one." In the present he concludes, "Curiously the practice of architecture has become increasingly disengaged from those dreams." This paper addresses inherent limitations in today's digital technology that restrict its ability to participate in the future design of the "fertile dream." It does not address the technology required, but the requirements of the technology.

summary	This exploration of early-stage, architectural design pedagogy is in essence, a record of an ongoing transformation underway in architecture, from its practice in the art of geometry of space to its practice in the art of geometry of space-time. A selected series of student experiments, from 1992 to the present, illustrate a progression in architectural theory, from Pythagorean concepts of mathematics and geometry, to the symbolic representation of space and non-linear time in film. The dimensional expansion of space, from xyz to xyz+t (time), represents a tactical and strategic opportunity to incorporate multisensory design variables in architectural practice, as well as in its pedagogy.

title	Secure and Fast Urban Visualization
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Due to the rising interest in urban visualization, a number of issues have emerged that need to be solved for practical application. The most prominent of these issues are: visualization performance and security. Visualization speed concerns the usability of urban visualization. In order to make urban visualization practical, it is necessary to completely hide all latency of loading data. Here we will demonstrate techniques like multi-threading, different rendering methods and level-of-detail that our platform uses to maintain interactive frame-rates in the face of the large amounts of data that are common in urban visualization environments. The secondissue, securing the geometry and image information contained in an urban model is of eminent importance for the owner of the data. We will point out a number of techniques that have been incorporated in our viewing platform in order to maintain a high level of data security: data compression and encryption, obfuscation of access keys, compression and encryption of executables. While perfect security is an unattainable goal, the multi-staged approach of security in our system significantly raises the cost of illegally obtaining access to the geometry or image data. By demonstrating solutions for both issues our framework serves as a viable platform for urban visualization.

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	The Level of Knowledge of CAD Objects within the Building Information Model
doi	https://doi.org/10.52842/conf.acadia.2003.173
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. 173-177
summary	The first generation of CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful graphics symbols. These entities only represented the geometrical properties of the architectural elements. With the present emerging generation of CAD systems, a new concept shifts a drawing-based model into a Building Information Model with the potential of modeling true architectural objects. Theoretically, these CAD objects will provide all related data to the designer describing the geometry, as well as any related data associated with how the object is actually used. The knowledge required to support an object should have structure to it. Different levels of knowledge need to be included, such as the geometrical information, which should be flexible enough to accommodate any type of shape and modification while keeping the object’s integrity as a unit and maintaining its relations to other objects. The CAD object concept, as remarkable as it is, might also have potential problems. It has some implications over the design process, as well as the architectural profession itself.

title	Digital Methods of Abstracting Forms from Nature
doi	https://doi.org/10.52842/conf.caadria.2003.695
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. 695-706
summary	Using mathematics and digital methods as a tool of investigation in both the natural and architectural form gives us a flexibility of exploring mu ltiple forms and allows us to implement new parameters into the mathematical framework to generate rather more complex architectural geometry. The method of generating architectural forms in this research is developed by selecting seashell as natural object and investigating its mathematical description then abstracting each mathematical parameter with others possible mathematical functions. Each selected mathematical function represents a mathematical abstraction of a specific seashell parameter as it occurs in nature. These enable the exploring of new mathematical relationships to generate a variety of architectural forms. In the seashell form these mathematical functions are limited to those that appeared in the actual geometry of shell such as logarithmic spiral, circle and ellipse. However, in the architectural form the limitations are less.

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	An XML Framework for Simulation and Analysis of Buildings
source	International Journal of Architectural Computing vol. 1 - no. 2
summary	This study focuses on the problem of how to structure spatial and component based building data with the intention to use it in the simulation and analysis of the performance of buildings. Special attention was paid to the interoperability and optimization of the resulting data files.The study builds its investigation onto XML (Extensible Markup Language) data modeling framework.The authors have studied different ways of arranging building information in XML format for effective data storage and have developed a data modeling framework called bmXML for buildings. Initial results are two-fold: a VBA application was developed to create the appropriate building model in AutoCAD with the intention to write building data in bmXML format, and a JAVA application to view the file thus created.This paper primarily focuses on the former, i.e. the AutoCAD application and the bmXML format.

title	DATA MODELING OF BUILDINGS WITH BMXML

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 533-540
summary	XML (extensible markup language) is emerging as a significant tool not only to model data but also to facilitate the seamless sharing of data between multiple domains. Therefore it can be quite powerful in modeling building data that must often be shared between large numbers of professionals. The focus of this study is how to use this paradigm in structuring spatial and component based building data with the intention to use it in the analysis and simulation of the performance of buildings. The framework developed by the authors consists of three components. An XML structure (bmXML) for storing building data, a VBA-AutoCAD-Application for generating the XML files (bmGenerator) and a JAVA-Application which reads the bmXML data and prepares the information for simulation purposes. This paper primarily focuses on theVBA-AutoCADApplication.

title	Online Database for Structural Details – DeTra

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. 373-381
summary	DeTra is a research project that arose from the question: “How is it possible to assist students and professionals in architecture, dealing with structural details?” Our solution is a structural detail database, which assists by presenting example solutions of similar designs. This research was conducted in two overlapping parts. The first part of the research included the definition of a structure and a language to describe structural details—flexible enough to enable complex computer based queries, simple enough to be understandable. Major problems were the inclusion of vague terms, different meanings for the same word, and different words for the same fact. The second part was to create internet-based computer software, which utilizes the developed concepts and allows their evaluation. Thereby the system can be used with different access methods to the same data collection. This approach intends to present both standard detail examples and project-related detail examples. For that reason the structural connections will be presented including all available project data. The information includes texts, sketches, drawings, photos, animations, and the database description. Our implementation handles this content. According to the holistic presentation of the search results a strong tool for evaluation is given to the user.

summary	Design space exploration is a long-standing focus in computational design research. Its three main threads are accounts of designer action, development of strategies for amplification of designer action in exploration and discovery of computational structures to support exploration. Chief amongst such structures is the design space - the network structure of related designs that are visited in an exploration process. There is relatively little research on design spaces to date. This paper sketches a partial account of the structure of both design spaces and research to develop them. It focuses largely on the implications of designers acting as explorers.

summary	Design considers function, fabrication, and aesthetics collectively. Computation is beginning to affect the competitive dynamics of design. Using algorithms, designers are exploring forms that are essentially “undrawable,” even with advanced modeling and direct manipulation techniques. Determining the appropriate functional characteristics may require the application of increasingly complex structural- and environmental-performance analysis techniques. To realize physically a design may require further geometric analysis and rationalization, and the use of complex computer-controlled fabrication techniques.

summary	Important progress towards the development of a system that enables multi-criteria design optimisation has recently been demonstrated during a research collaboration between Autodesk’s DesignScript development team, the University of Bath and the engineering consultancy Buro Happold. This involved integrating aspects of the Robot Structural Analysis application, aspects of the Ecotect building performance application and a specialist form finding solver called SMART Form (developed by Buro Happold) with DesignScript to create a single computation environment. This environment is intended for the generation and evaluation of building designs against both structural and building performance criteria, with the aim of expediently supporting computational optimisation and decision making processes that integrate across multiple design and engineering disciplines. A framework was developed to enable the integration of modeling environments with analysis and process control, based on the authors’ case studies and experience of applied performance driven design in practice. This more generalised approach (implemented in DesignScript) enables different designers and engineers to selectively configure geometry definition, form finding, analysis and simulation tools in an open-ended system without enforcing any predefined workflows or anticipating specific design strategies and allows for a full range of optimisation and decision making processes to be explored. This system has been demonstrated to practitioners during the Design Modeling Symposium, Berlin in 2011 and feedback from this has suggested further development.

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.

title	From Intuition to Precision

summary	Design has been described as making inspire decisions with incomplete information. True, we may use prior knowledge, we may even think we understand the causalites involved, but what really matters is exploration: of new forms, of new materials, and speculation about the response to the resulting effects. Essentially, this exploration has its own dynamics, involving intuition and spontaneity, and without which there is no design. But of course we all know that this is not the whole story. Design is different to 'craft'; to directly 'making' or 'doing'. It necessarily has to be predictive in order to anticipate what the consequence of the 'making' or 'doing' will be. Therefore we inevitably have to counter balance our intuition with a well developed sense of premeditation. We have to be able to reason about future events, about the consequence of something that has not yet being made. There is always going to be an advantage if this reasoning can be achieved with a degree of precision. So how can we progress from intuition to precision? What abstractions can we use to represent, externalize and test the concepts involved? How can we augment the cognitive processes? How can we record the progression of ideas? And, how do we know when we have arrived? Design has a symbiotic relationship with geometry. There are many design issues that are independent of any specific configurations. We might call these “pre-geometric” issues. And having arrived at a particular configuration, there may be many material interpretations of the same geometry. We might call these “post-geometric” issues. But geometry is central to design, and without appropriate geometric understanding, the resulting design will be limited. Geometry has two distinct components, one is a formal descriptive system and the other is a process of subjective evaluation.

summary	Design computation based on data flow graph diagramming is a well-established technique. The intention of DesignScript is to recognise this type of data flow modeling as a form of ‘associative’ programming and to combine this with the more conventional ‘imperative’ form of programming into a single unified computational design application. The use of this application is intended to range from very simple graph based exploratory ‘proto-programming’ as used by novice end-user programmers to multi-disciplinary design optimisation as used by more experienced computational designers.
