summary	In this paper we present a model for handling design information in the early design phases. This model can be used for representing both vague and exact defined information. The first part describes the difficulties involved in using CAD in the architectural design process and the characteristics of that process. Then we give a description of the design information and its representation during the design process. Next an overview of the architectural design process describes how design information is added and manipulated during the design process in order to achieve an effective result. Finally, we include a brief description of a simple prototype program to illustrate how this theory acts in practice.

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.

summary	The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

title	Geometric and Solid Modeling
source	Morgan Kaufmann
summary	Solid modeling is rapidly emerging as a central area of research and de- velopment in such diverse applications as engineering and product design, computer-aided manufacturing, electronic prototyping, o -line robot pro- gramming, and motion planning. All these applications require represent- ing the shapes of solid physical objects, and such representations and basic operations on them can be provided by solid modeling. As a eld, solid modeling spans several disciplines, including mathemat- ics, computer science, and engineering. In consequence, it is a broad subject that must accommodate a diversity of viewpoints and has to meet a diversity of goals. Sometimes, this diversity of goals can lead to con icting demands. Current thinking on the subject views the proper resolution of these con- icts to be application-dependent. That is, it is no longer thought realistic to envision a comprehensive solid-modeling system that satis es the needs of all potential users. Rather, as it is argued, we should concentrate on con- structing a software environment in which many tools for geometric and solid computation are available and can be combined with ease as appropriate for the speci c application under consideration.

title	Um levantamento de requisitos gerais para o desenvolvimento e posicionamento de DOOTERS – um aplicativo lúdico de listas de tarefas para iPhone [A survey of general requirements for developing and positioning DOOTERS - a to-do list application for iPhone]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 191-195
summary	DOOTERS is a to-do list application for iPhone which entertains and motivates the user to get things done. It was developed based on requirements obtained trough: 1. the study of several personal information organizing methods (Covey, 1989; Allen, 2005; Foster, 2006); 2. answers to a task lists user focused questionnaire; 3. observation of to-do list users while creating lists and organizing tasks; 4. comparison of digital and non-digital task list media (paper, computer and mobile device); 5. analysis of profiles, behaviors and to-do list applications for iPhone. In this paper, the authors present the process of obtaining requirements for developing and positioning DOOTERS.

doi	https://doi.org/10.52842/conf.ecaade.1989.x.c7m
summary	The paper presents an approach to the problems of architectural design aided by Artificial Intelligence techniques that can solve the difficulties related to combinatorial explosion, often encountered in the past. Three expert systems, dubbed "reasoners", capable of some elementary design work and a hypothesis for their interaction have been developed. Reasoner A has an "analogical" view of space. A notion of conflict, managed by means of fuzzy logic, has been introduced. It corresponds, in an intuitive and straightforward fashion, to the common notion of conflict or contradiction in real space as a consequence of improper overlapping of actual physical objects or of their functional pertinence. Reasoner B works on formalized models of building objects. It designs new patterns from given patterns taken as defaults. Reasoner C picks up from an archive of patterns the one which best suits a list of given goals. Design is the result of interaction between the three reasoners. Finally, the proposed schema raises questions about formal structures ("images") and about the nature of culturally-linked options ("memory") on which some preliminary considerations are made. Prototypes of the reasoners are operating at the Instituto di Edilizia of the University of Ancona, Italy.

title	Messina 1908: The Invisible City

summary	The initial purposes of this work were to build a 3D model of the old city of Messina and to reconstruct a walk through it; to understand the "Ghost city," the parts that form it, and the rules of its plan, which are explicit in some cases but hidden most of the time; to measure its space, appreciate the similarities to and differences from modern city plans, and use the information to improve the plans of tomorrow. It might seem a useless study of a nonexistent city, and yet during the months of detailed work, of patient reconstruction from the surveys and photographs of the city destroyed in 1908, we began to consider how it was still possible to obtain spatial values of and to project behaviors in the lost city, in other words, to practice tests on memory that are very interesting for people working in a context in which memory no longer exists. The work presented here is the first stage of a more complex research project still to be carried out on Messina as it was at the end of the nineteenth century. Here we constructed a 3D model of some parts of the city prior to the earthquake of 1908 and made a five-minute video, using cartoon techniques, of an "impossible" walk through the city. The fragments of the city were reconstructed from available documentary sources, primarily photographic images, which tended to be of the most important places in the city.

title	The Design of Buildings as Changes of Known Solutions: A Model for “Reasoner B” ; Reasoner B" in the Castorp System
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 7.3.1-7.3.9
doi	https://doi.org/10.52842/conf.ecaade.1989.x.u3h
summary	The paper presents a study aimed at the modelization of a design operation of perturbation of an architectural framework in order to comply with a series of given design specifications. A formalized representation of the building object is assumed, Artificial Intelligence techniques are adopted to work on it. It is assumed that the computer carries out deformations starting from one of these structures in order to attain to a solution consistent with project specifications. A description of the structures employed for the representation of the building body (matroids) is firstly proposed. A planning theme is then assumed, as an example, whose main feature is to maintain the outer perimeter of a dwelling, to change its internal distribution in such a way as to resemble as closely as possible to the original and yet meaningfully alter its typology.

doi	https://doi.org/10.52842/conf.ecaade.1989.x.w4j
summary	The educational outlines used by the German, and most other European schools of architecture, have certain differences in comparison to an American school. This is partly due to the different tasks each group has to fulfill. Our architects not only plan their projects in detail, but in many cases they have to supervise the site as well. Most importantly, they also check on all communications between those participating in the design process. Skills of architects leaving their schools and entering into practical life generally need further training. Since CAAD is becoming more and more involved in architectural design studios of various sizes, the development of skills in this area should be shifted towards the period of studies. Thus, schools and staffs have to react to meet the needs of the present facts.

title	Extrusion, Assemblage, Joint and Connection in the Workshop for Gas Production by Giuseppe Terragni
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 9.16.1-9.16.9
doi	https://doi.org/10.52842/conf.ecaade.1989.x.g7l
summary	Turning over the catalogues' pages of the first show of rational architecture, the strongly contrasting pictures of the model presented by Terragni remain impressive. The project for a "Workshop for Gas Production", designed by the 23 year old architect from Como, reveals the presence of an early talent and the originality of his research. Although inspired by the contemporary European architecture, the work of Terragni does not attempt to academically repeat former precedents. Although Terragni's project and many among the other exhibited works share an analogy of forms, the syntax of the Como architect appears more mature and complex. This essay and the accompanying original drawings are dedicated to the de-constructivist nature of the design operations as well as to the clarification of the messages embodied in the specific program.
