summary In the conventional way of teaching architecture, it is common to think of design as the final synthesis of an intellectual process (composizione in Italian) integrating different elements from different curriculum subjects: history, structural analysis., technology, regional and urban planning, and so on. These elements, being comprehensive of their specific domains, together build the project. This process is supported by a long traditional that cannot easily be modified; however, we must not consider it to be the only one. Architectural practice should be much more. The Scuole di Architettura has walked a long and difficult road in the last thirty years., with a significant widening of interest in social, political, and economic issues. There have been recurring attempts at epistemological reformulation in some areas. There has been an acknowledgment of a crisis in contemporary town planning and a dimming of several certitudes that had developed with the birth and growth of the modernist school. And there has been a weakening of the promises that had given life to the vigorous discussion about town and regional planning. All of this leads to a reconsideration of the meaning and the deeper assumptions that the project implies, a question mark at the center of the human sciences that architectural practice involves. The old tradition., which assigned composition a central role in the project, is no longer sufficient because it is related to a reductive reading of epistemology that views human sciences as defining segments of physical knowledge of the actual world. Contemporary reflection on the difference between understanding and unfolding, together with the attention given to interpreting a moment as compared to purely describing one, gives to the project the task of inquiry instead of solution.

title Modeling the Emergence of Schemas in Design Reasoning
source Design Computing Unit, Department of Architectural and Design Science, University of Sydney, 1989. pp. 173-205. CADLINE has abstract only
summary The authors explore how neural networks can be used to model important aspects of design reasoning: the way design involves memory; and a 'holistic' kind of reasoning by which designs appear to emerge from that memory. A simple neural network is constructed to demonstrate how information about schemas (in this case, room types) is stored implicitly after exposure to a number of examples of specific rooms. We then demonstrate how new room types emerge from this information. The paper includes a discussion of design, a discussion of schemas from a psycholinguistic perspective, a technical explanation of neural networks and the demonstration of an implemented examples

summary This paper presents an overview of neural network (connectionist) systems and their potential contribution to computer-aided design. The authors discuss the appeal of neural networks and some of the problems. The major contribution to design is in the representation and manipulation of schemas. A neural network system can be 'taught' various examples (such as room descriptions). The system then apparently recognizes schemas (room types) and can produce novel but sensible combinations of descriptions constituting new types. A simple handworked example is presented, and the learning and reasoning mechanism is explained

title Knowledge-based Design Systems in Architecture : a Linguistic Perspective
source Knowledge Based Systems in Architecture. Helsinki: Acta Polytechnica Scandinavica, 1989. pp. 27-36
summary The separation of syntax and semantics in systems for the production of architectural designs is discussed. In producing designs we are less interested in mapping between buildings and their meaning than in mapping between an intended meaning and a design description of a kind that can be constructed, a mapping between semantic and syntactic realms. The thesis of this paper is that it is both feasible and operationally useful to separate the consideration of interpretation and syntactic generating in design. The authors first examine the possibility of operating in the syntactic realm, then the possibility of operating in the interpretative realm. Finally they examine how a design system might combine interpretative and syntactic systems

title Lost In Hyperspace: Cognitive Mapping and Navigation in a Hypertext Environment, Chapter 7
source Hypertext: Theory Into Practice, Edited by McAleese, Ray., Ablex Publishing Corporation, New Jersey
summary This paper describes an experiment which looks at how the users of a hypertext document cognitively represent its layout. A document was formed into three different hypertext styles and was presented to the readers, they were then asked a series of questions about information contained in the hypertexts. The way the users found the answers and the time taken was recorded, they were also ask to lay out cards, with reduced versions of the screen on them, on a board and as they thought them to be arranged in the document and also to draw any connecting hypertext links they thought existed between these screens. The users selected for this experiment consisted of 27 university undergraduates 15 male and 12 female with a mean age of 20.5 years with little or no computing experience. They were each assigned one of the three hypertext methods and their performance was recorded. The three methods consisted of a hierarchical, a mixed and an index based method.

title Archaeological Site Reconstruction With AutoDesk's 3D Studio
source CSA Newsletter Vol 7:3 Nov 1994
summary 3D Studio is an IBM-compatible computer modeling program that enables users to create three-dimensional renderings of a variety of objects. In its ability to import a wide variety of maps and other images, 3D Studio allows for the realistic rendering of models created within AutoCAD or other 3D CAD packages. Over the past year, the Homol'ovi research program has been utilizing this software to create near photo-realistic renderings of conjectural site models. My own interests in three-dimensional computer modeling developed out of work at the site of Homol'ovi IV, a 150-room pueblo site located near Winslow, Arizona. The site was situated upon a steep 30-meter bluff with a bedrock cap. Approximately 24 rooms were located on top of the bedrock cap, with another 125 rooms situated on the slope of the butte. During the 1989 field season five structures were excavated, while a separate crew worked clearing and mapping the tops of walls. Mapping was accomplished with a Topcon EDM/theodolite station, and a standard map was created from this process. (See Fig. 3.) While the map was sufficient to show the general layout of the site, I remained unsatisfied; a 2D plan view simply did not convey the vertical dimension of the pueblo. At this point the Homol'ovi Research Program purchased a copy of AutoCAD in order to begin exploring three-dimensional mapping and modeling.

summary Through the integration of microcomputer-aided draughting (CADr), and in particular with AutoCAD, the industries most extensively used CADr program, and automated routines for the production of bills of materials, a dramatic incr-ease in productivity is possible in the architectural design domain. Working from a variety of material take off methods complete cost estimates may be achieved through the manipulation of drawing data and exchanging the information with third-party estimating software. However, the area of study is currently at a formative stage of development and full integration, although technically feasible, is rarely attempted. Therefore, the paper comments on the development of 'in-house' routines using AutoCAD's data extraction features and AutoLISP; reviews current commercial systems of interfacing AutoCAD with bills of materials and automated specification routines; and, finally, discusses possible future advances in this major area of study.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title Relational Modeling: A Basis for Computer-Assisted Design
source The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 123-136
summary Today's computer assisted design (CAD) systems automate traditional ways of working with tracing paper and pencil, but they cannot represent the rules and relationships of a design. As hardware becomes faster and memory less expensive, more sophisticated fundamental software technologies will be adopted. This shift in the basis of CAD will provide powerful capabilities and offer new ways to think about designing. Recently parametric design, a technique for describing a large class of designs with a small description in code, has become a focus of attention in architectural computing. In parametric CAD systems, design features are identified and keyed to a number of input variables. Changes in the input values result in variations of the basic design. Based on conventional software technologies, parametric design has been successfully applied in many design domains including architecture and is supported by several commercial CAD packages. A weakness of parametric techniques is the need to predetermine which properties are input parameters to be varied and which are to be derived. Relational modeling is a simple and powerful extension of parametric design that overcomes this weakness. By viewing relations as reversible rather than one-way, any set of properties can be chosen as input parameters. For example, a relational model that calculates the shadow length of a given building can also be used to calculate the building height given a desired shadow length. In exercising a relational model the designer is not limited to a pre-selected set of input variables but can explore and experiment freely with changes in all parts of the model. Co is a relational modeling environment under development on the Macintosh-II computer, and Co-Draw, a prototype CAD program based on Co. Co's relationaI engine and object-oriented database provide a powerful basis for modeling design relations. Co-Draw's interactive graphics offer a flexible medium for design exploration. Co provides tools for viewing and editing design models in various representations, including spreadsheet cards, tree and graph structures, as well as plan and elevation graphics. Co's concepts and architecture are described and the implications for design education are discussed.

summary For over 10 years the author has been a teacher in the field of "computer application in architecture" at the Fachhochschule. Since 1985 he regularly has been taking part in the conferences of A.I.I.D.A. (Arbeitskreis INFORMATIK IN DER ARCHlTEKTENAUSBILDUNG). All the faculties of architecture at the Fachhochschulen (about 10) can send their representatives of CAAD to the conferences. A.I.I.D.A. has been having 2 conferences a year since 1985. At the last conference in Wiesbaden a paper with statements of A.I.I.D.A. for the further education in CAAD was finished. The author presents and explains this paper. On the other hand he shows the actual education program of CAAD of his faculty. The education in CAAD started in 1972 with basic information without practical elements. Now the practical work with the workstation is talking most of the time . The computer application is available for subjects like Building Economics, Building and Structure Design and others. With his assistant the author developed programs of the field of Building Economics. In 1986 he started introduce CAD with AutoCAD in the education program. Now also other colleagues start to integrate CAAD into their subjects.

summary Computer assistants to building process management are not able nowadays to efficiently work out the problems generated by the increased complexity of designing. Actual difficulties depend, on one hand, on the fact D.B.M.S. that have been developed on other environments than CAAD, and on the other hand, on the fact that architectural design process is scarcely formalized. At the Department of T.E.C.A., at the University of Rome, a PhD research program is aimed to overcome difficulties, working out techniques of information management based on Knowledge Engineering and particularly on Knowledge Base Management Systems and Expert Database Systems. At present a prototype system is being developed, that can manage existing technical information, connected with buiIding process.

title A Primitive-Instancing Interactive 3-D Modeling System for Spatial Design Studies
source The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 457-468
summary The authors have developed a basic, interactive, primitive-instancing 3-D modeling system (CAADF), which is based on a high-speed 3-D color graphic workstation, and have tested its potential ability to support spatial design studies in an architectural design studio. After- a review of work performed by a student with the system, this paper concludes that this system provides an attractive environment for spatial design studies which conventional CAD systems have not achieved. The interactive process of 3-D modeling in perspective or isometric view images and the dynamic viewing utility are the most successful features of the system. In contrast to those advantages, the resolution of color graphic display is a limitation of the system. The authors conclude that if sufficiently many appropriate 3-D geometric primitives are supported by a CAD system, a primitive instancing method can significantly reduce the work entailed in object modeling.

title Compositing 3D Images with Antialiasing and Various Shading Effects
source IEEE Computer Graphics & Applications 9 no. 2: 21-29
summary A method is proposed for compositing 3-D images produced by different programs, taking depth order into consideration. The method can add the following effects to composited images: antialiased images with scaling are displayed by a simple algorithm; the algorithm can add shading effects due to various types of light, such as area sources and skylight; and ray tracing can be performed in localized regions, producing realistic results without the computational expense of ray tracing the whole image. In addition to the above processes, such shading effects as fog and texture mapping can be processed with conventional methods. Thus, it becomes possible to display complex scenes with various shading effects, using relatively small computers. The multiscanning method used for antialiasing and a data structure for processing it are described. Examples are presented to demonstrate the capability of the system.

summary In the period 1945-1989, the spatial transformation of Lodz was accompanied by the development of hospital facilities, which are an essential part of cultural heritage of the post-war history of the city. They represent a set of cultural, ethical and aesthetic standards of their time, the knowledge and acceptance of which may play a key role in the development of the tradition of the city. The studies and efforts made to systemize the advantages of the discussed architecture as well as its popularization are an urgent issue, due to the currently occurring intensive and, to a large extent, uncoordinated processes of transforming hospitals built after 1945. It is worth emphasizing that the post-war Lodz architecture is a kind of excellent historic record deserving common acceptance, thorough documentation and protection.

summary We present an integrated set of programs as CAD-tools for the design of shapes, evaluation of stress field and displacements of tensile membrane structures as well as a way to find out their surface patterns. In early times simulation of physical small models has been used to obtain a phenomenological view rather than quantitative information about these structures. A progressive way has been thought to make a comprehensive an practical approach to this kind of structure, characterized by its ability to offer displacements of long range. We propose like a first steep a rough simulation through elastic member models or elastic-surface models. An iterative process starts, based on visualizations through different peripheric devices (screened and plottered graphic outputs). This first steep ends by the formulation of an optimum geometric performances of the structure. The resulting geometry serves like a source structure for a more accurate calculus achieved by the Finite Element Method. Discretization of the continues structure is carried out in a network of tiny triangular elements. Finally, 3-D realism techniques has been used to represent the form adopted or stress field calculated or both at the same time, by an adequate use of the color attributes of the finite elements.
