title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs

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	Towards Integrated Performance-Based Generative Design Tools

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	Architectural-IT and Educational Curriculumns - A European Overview
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	The paper summarizes the analysis of data on european architecture schools, collected in the eCAADe-conferences during the 1990s. Computer-Aided Design has developed into architectural information and communication technology (ICT), to become commonplace in architectural education. However, the general held views on new media use in the schools seems to be slightly optimistic. On the other hand, the invisible more common ICT use (writing, surfing, emailing) accounts for a lot more of the volume of activity than generally appreciated. The major hardware platform in european architecture schools is PC/Windows (90-95%) with Linux and Unix commonly used in servers (25-35%). Macintoshes are also widely used (50-55%). MS Office (90-95%) and PhotoShop (85-90%), are used widely in the schools. The Graphic and DTP tools PageMaker, QuarkXpress, Illustrator, Freehand are also common (30-50%). AutoCAD is the market leader in CAD platforms (80-90%), followed by ArchiCAD. MicroStation/Bentley also has a significant presence in the schools (35-40%). 3DStudio is the most common 3D-modelling tool (80-85%), followed by formZ (35- 40%). Less common (15-25%) are Rhino, Maya, Alias, Lightscape and Radiance.

title	Survey of Architectural-ICT in the Educational Curriculumns of Europe
doi	https://doi.org/10.52842/conf.ecaade.2003.601
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 601-606
summary	The paper documents the findings of the post-graduate study carried out among the 180 European schools of architecture in more than 30 countries during 2002-2003. The objective has been to describe the role of ""modern digital information technology"" and to give an understandable and measurable overview the current architectural education and its relation with ICT and CAAD. The study material has been collected with a web-survey, with questionnaires to eCAADe-conference participants in Helsinki 2001 and Warsaw 2002, and with direct email-contacts to schools’ key-persons. Computer-aided design has developed into architectural information and communication technology (ICT), to become the main tool of the majority. The general image of new media use in the architectural schools seems to be slightly too positive. The invisible or ”normal” ICT-use - writing, surfing, emailing - has a lot more volume than documented. The major hardware platform in european architecture schools is PC/Windows (90-95 %), Linux and Unix are used also commonly (25-35 %). Macintoshes are also used much more widely within architecture (50-55 %) than within the common computing platforms. MS/Office (90-95 %) and PhotoShop (85-90 %) are obviously also used widely in the architecture schools. Graphic tools PageMaker, QuarkXpress, Illustrator, Freehand are common tools for architecture students (30-50 %). AutoCAD is ”the marketing leader"" in architectural platforms (80-90 %) followed by ArchiCAD (60-65 %). MicroStation/Bentley has also a remarkable volume in the schools (35-40 %). 3DStudio is the most common 3D-modelling tool (80-85 %), followed by formZ (35-40 %). Slightly less volume but still remarkable (15-25 %) have Rhino, Maya, Alias, Lightscape and Radiance.
