summary This work invests on delimitation of a Geometric Modeling study program directed to students at the initial stages of Architecture. It is considered that the studies promote a qualified control of the form based on recognition of parameters which define it, moreover it also allows the enlargement of the students geometric vocabulary, important to the architectural design activities. In this way, the program advances on the appropriation of new concepts which surround the investigations on architectural design processes, such as the concept of shape grammar. Observing analysis and architectural composition practices based on such concept, contents of geometric modeling which are already being used in the context of post-graduation are identified to be transposed to the graduation context, along with the initial teaching practices of architectural design. The results refer to making the didactic material available, these materials have the objective of building references for the development of design practice which explore the reflection about the processes of creation and composition of architectural form in their geometric aspects.

title Elemental Methods for Integrated Architectures: Experimentation with Design Processes for Cable Net Structures
source International Journal of Architectural Computing vol. 6 - no. 4, 453-475
summary Tension active systems are compelling architectural structures having an intimate connection between structural performance and the arrangement of material. The direct flow of structural forces through the material makes these systems attractive and unique from an aesthetic point of view, but they are a challenge to develop from a design and an engineering perspective. Traditional methods for solving such structural systems rely on both analog modeling techniques and the use of highly advanced engineering software. The complexity and laborious nature of both processes presents a challenge for iterating through design variations. To experiment with the spacemaking capabilities of tension active systems, it is necessary to design methods that can actively couple the digital simulation with the analog methods for building the physical structure. What we propose is a designer-authored process that digitally simulates the behaviors of tension active systems using simple geometric components related to material and structural performance, activated and varied through elemental techniques of scripting. The logics for manufacturing and assembly are to be embedded in the digital generation of form. The intention is to transform what is a highly engineered system into an architectural system where investigation is as much about the determination of space and environment as it is about the arrangement of structure and material.

summary This paper begins with a simple proposition: rather than mimicking the geometric structures found in nature, perhaps the most effective modes of sustainable fabrication can be found through understanding the nature of materials themselves. Material becomes a design parameter through the constraints of fabrication tools, limitations of material size, and most importantly the productive capacity of material resistance—a given material’s capacity and tendencies to take shape, rather than cutting shape out of material. ¶ Gridshell structures provide an intriguing case study to pursue this proposition. Not only is there clear precedent in the form-finding experiments of Frei Otto and the Institute for Lightweight Structures, but also the very NURBS based tools of current design practices developed from the ability of wood to bend. Taking the bent wood spline quite literally, gridshells provide a means that is at once formally expressive, structurally optimized, materially efficient, and quite simply a delight to experience. The larger motivation of this work anticipates a parametric system linking the intrinsic material values of the gridshell tectonic with extrinsic criteria such as programmatic needs and environmental response. ¶ Through an applied case study of gridshells, the play between form and material is tested out through the author’s own experimentation with gridshells and the pedagogical results of two gridshell studios. The goal of this research is to establish a give-and-take relationship between top-down formal emphasis and a bottom-up material influence.

summary The proportion of planning activity that concerns existing buildings is increasing steadily throughout Europe. In Germany it is estimated that already two thirds of architectural planning tasks are related to revitalisation, modernisation, conversion and reconstruction. For these types of projects in particular, clients are interested in obtaining an estimate of the building costs as early as possible. Because many details are unknown or can only be guessed, it is often difficult to make a reliable estimate. This article describes a software concept for the rapid, sketch-based capture of data on site with a view to obtaining a cost-assessment for a series of different revitalisation variants using a stochastic approach.

summary The association of complexity and geometry was the starting point for an academic project at the chair of Computer Aided Design in Detmold. The students were asked to analyze a complex structure - taken from nature, art, technology or society - regarding the underlying geometrical rules and principles. The translation of these abstract geometric principles (logarithmic spiral, polyhedron, rotational solids, mesh-work, double helix…) into a three-dimensional structure was then realized in Rhinoceros. The 3D-modeling was followed by a transformation- and optimization-process of the initial shape by using the evolutionary principles of mutation and selection. The set-up for these variations followed predefined rules and principles for the manipulation of the original structure.

title Study of Architectural Shape Formation in Comparison with Natural Morphogenesis Using Computer Simulation
source Proceedings of the 8th European Architectural Endoscopy Association Conference
summary Geometric accuracy of architectural computer models allows to percept and to analyze the three-dimensional spatial compositions using computer images. The concepts and methodology of modern interdisciplinary science, in particular fractal geometry, have already been successfully applied in the various scientific fields, as astronomy, physics, chemistry, biology. Modern ecological paradigm does not separate human life and anthropogenic world from the natural environment considering all as unitary nonlinear ecosystem. The analysis of the architectural shape formation is a part of the study of morphogenesis in such different worlds, as non-living and living nature and man-made forms – real as well as virtual architecture.

title Computing Spatial Qualities For Architecture

summary Computational representation of spatial qualities can lead us to a better understanding of how we construct spatial concepts. Analyses of spatial qualities can support architects in reasoning about the form of a configuration, helping them predict the consequences of a design. ¶ In this paper we present three definitions (enclosure, viewfield, continuity) that describe experiential qualities of architectural spaces. Our project aims to provide computable definitions to these qualities to describe common spatial experiences that are implicitly understood by architects. The description, using familiar terms, reveals the analytical structure of spatial qualities that is based on the geometry of the physical elements. ; We therefore introduce a graphic editor, Descriptor, that provides visualization of spatial qualities as the designer diagrams building elements. The system calculates perceived relationships (surrounded, visible, nearby, nearest) between a viewpoint and the architectural elements based on their geometric properties such as location and distance. The relationships are the components of the three qualities we define. We also present a use scenario to demonstrate how one might use our Descriptor system during early design. ¶ Descriptor is an attempt to formalize descriptions of the spatial qualities to help beginners understand how to make design decisions. In the future, we plan to extend the set of qualities and add detailed attributes of the physical elements to the system.

summary There is a close relation between building design and fabrication. However still it is mostly a sequential process where the fabrication with its geometric chances and limitations is only to a small extend taken into account in early design phases. In this paper we describe a protoype form work project, realized out of styrofoam cut out with a CNC hot wire-cutting system and coated with the Claraporon coating system. Due to the linear nature of hot wire cutting the surfaces that can be created are ruled surfaces. They are discussed in a more general way as well as first exercises with ruled surfaces in teaching.

title Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

summary “Why do we have to change? We’ve been building buildings for years without CATIA?” Roger Norfleet, a practicing architect in his thirties poses this question to Tim Quix, a generation older and an expert in CATIA, a computer-aided design tool developed by Dassault Systemes in the early 1980’s for use by aerospace engineers. It is 2005 and CATIA has just come into use at Paul Morris Associates, the thirty-person architecture firm where Norfleet works; he is struggling with what it will mean for him, for his firm, for his profession. Computer-aided design is about creativity, but also about jurisdiction, about who controls the design process. In Architecture: The Story of Practice, Architectural theorist Dana Cuff writes that each generation of architects is educated to understand what constitutes a creative act and who in the system of their profession is empowered to use it and at what time. Creativity is socially constructed and Norfleet is coming of age as an architect in a time of technological but also social transition. He must come to terms with the increasingly complex computeraided design tools that have changed both creativity and the rules by which it can operate. In today’s practices, architects use computer-aided design software to produce threedimensional geometric models. Sometimes they use off-the-shelf commercial software like CATIA, sometimes they customize this software through plug-ins and macros, sometimes they work with software that they have themselves programmed. And yet, conforming to Larson’s ideas that they claim the higher ground by identifying with art and not with science, contemporary architects do not often use the term “simulation.” Rather, they have held onto traditional terms such as “modeling” to describe the buzz of new activity with digital technology. But whether or not they use the term, simulation is creating new architectural identities and transforming relationships among a range of design collaborators: masters and apprentices, students and teachers, technical experts and virtuoso programmers. These days, constructing an identity as an architect requires that one define oneself in relation to simulation. Case studies, primarily from two architectural firms, illustrate the transformation of traditional relationships, in particular that of master and apprentice, and the emergence of new roles, including a new professional identity, “keeper of the geometry,” defined by the fusion of person and machine. Like any profession, architecture may be seen as a system in flux. However, with their new roles and relationships, architects are learning that the fight for professional jurisdiction is increasingly for jurisdiction over simulation. Computer-aided design is changing professional patterns of production in architecture, the very way in which professionals compete with each other by making new claims to knowledge. Even today, employees at Paul Morris squabble about the role that simulation software should play in the office. Among other things, they fight about the role it should play in promotion and firm hierarchy. They bicker about the selection of new simulation software, knowing that choosing software implies greater power for those who are expert in it. Architects and their collaborators are in a continual struggle to define the creative roles that can bring them professional acceptance and greater control over design. New technologies for computer-aided design do not change this reality, they become players in it.

summary A perspective represents space as seen from the outside, with the eye of the transcendental subject; an eye –represented by a geometric view point– which not only sees a space, but a space as it is seen by the subject. Motion is inherent to our experience of space which is not fixed and static –like a perspective assumes– but dynamic.

title Reinterpreting Rasmi Domes with Geometric Constraints:A Case of Goal-seeking in Parametric Systems
source International Journal of Architectural Computing vol. 6 - no. 4, 375-395
summary Geometry has long been a generator of architecture. In traditional Persian architecture, Rasmi domes project a drawing onto a predefined 3D geometry. In fact, the word 'rasmi' and the verb for drawing in Persian have the same linguistic root. Projection is readily done in manual drawings or conventional CAD programs. From a constraint perspective, the dome is constrained by the drawing and the 3D geometry. If the latter constraint is replaced by invariance of distance on the original drawing, a class of domes results, but members of this class cannot be computed conventionally. Class members are developable from a planar layout of triangles, which is, in turn, generated by a simple drawing rule. This yields a parametric structure of four parameters. Three determine the initial planar diagram. One determines configuration. Further, domes in the class are mechanisms: they are not fully specified by the constraints and parameters. We develop the geometric constraints representing the location of the defining points of a dome and present a goal-seeking algorithm to solve the constraints within a propagation-based parametric modeling system.

summary A paradigm shift in the world of architecture brought by the recent developments in visualization and communication technology not only offers us drastically different ways to collaborate, but also questions traditional location dependent collaborations. This new technology offers us new possibilities for a more phenomenologically rich mode of creative activity and participation. The goal of the Participatory Design Studio was to allow architecture students in multiple locations to collaborate in real-time by sharing computational resources, geometric datasets, and multimedia content including high-definition video. The technologies involved in this research include the National LambdaRail (layer 3, PacketNet with 1Gb/s connection) and CA*net 4 (Canadian broadband layer 2 with 10gb/s lightpath connectivity) allowing Standard Definition videoconference, utilization of Deep Computing Visualization, Remote Visual Networking (RVN) and Web Service access and control of the APN devices through the dashboard solution that makes integration seamless to the workflow and transparent to the user.

title Digital Fabrication Production System Theory: Towards an Integrated Environment for Design and Production of Assemblies
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary A Digital Fabrication Production System (DFPS) is a concept describing a set of processes, tools, and resources that will be able to produce an artifact according to a design, fast, cheap, and easy, independently of location. A DFPS project is a complex assembly of custom parts that is delivered by a network of fabrication and assembly processes. This network is called the value chain. The workflow concept of a DFPS is the following: begin design process with a custom geometric form; decompose it into constructible parts; send the part files for fabrication to various locations; transport all parts at the construction site at the right time; finally, assemble the final artifact. Conceptually it means that based on a well structured value chain we could build anything we want, at anyplace, at controllable cost and quality. The goals of a DFPS are the following: custom shapes, controllable lead time, controllable quality, controllable cost, easiness of fabrication, and easiness of assembly. Simply stated this means to build any form, anywhere, accurately, cheap, fast, and easy. Unfortunately, the reality with current Digital Fabrication (DF) projects is rather disappointing: They take more time than what was planned, they get more expensive than what was expected, they involve great risk and uncertainty, and finally they are too complex to plan, understand, and manage. Moreover, most of these problems are discovered during production when it is already late for correction. However, there is currently no systematic approach to evaluate difficulty of production of DF projects in Architecture. Most of current risk assessment methods are based on experience gathered from previous similar cases. But it is the premise of mass customization that projects can be radically different. Assembly incompatibilities are currently addressed by building physical mockups. But physical mockups cause a significant loss in both time and cost. All these problems suggest that an introduction of a DFPS for mass customization in architecture needs first an integrated theory of assembly and management control. Evaluating feasibility of a DF project has two main problems: first, how to evaluate assemblability of the design; second, how to evaluate performance of the value chain. Assemblability is a system’s structure problem, while performance is a system’s dynamics problem. Structure of systems has been studied in the field of Systems Engineering by Network Analysis methods such as the Design Structure Matrix (DSM) (Steward 1981), and the liaison graph (Whitney 2004), while dynamics of systems have been studied by System Dynamics (Forrester 1961). Can we define a formal method to evaluate the difficulty of production of an artifact if we know the artifact’s design and the production system’s structure? This paper formulates Attribute Process Methodology (APM); a method for assessing feasibility of a DFPS project that combines Network Analysis to evaluate assemblability of the design with System Dynamics to evaluate performance of the value chain.

summary This paper outlines the digital design processes involved in the design and construction of the new Elephant House at Copenhagen Zoo. Early design concepts for the canopy were tested using physical sketch models. The geometric complexity of these early physical models led to the involvement of the Specialist Modelling Group and the use of the computer to digitally sketch 3D CAD models. After many studies, the complex form of the canopies was rationalised using torus geometry. A computer program was written to generate the canopy glazing and structure. This parametric system was developed to be a design tool, and was developed by an architectural designer working with the team. Through its use the team were able to explore more design options, and alter the design farther along in the design process; however, this generative tool was created largely as a CAD efficiency tool. Another series of computer programs were written to generate and populate a shading system based on environmental analysis. Unlike the computer program that generated the structure and glazing, this program was not developed to make the generation of complex geometric structures more efficient, but developed to explore computational approaches that would have been impossible without the computer. Most of the canopy’s design was communicated to fabricator through a geometry method statement, a method that has been proven to be effective in the past. The project completed in June 2008.

title The Computer Methods of Construction Spiral Structures
source Proceedings of the 8th European Architectural Endoscopy Association Conference
summary The object of our research is geometric characteristics of spiral structures which are widely spread in nature (cones, sunflower beds…). It is a well-known fact that there is a proportional intercommunication according to the “golden section”. The correlation of the quantity of “right” and “left” spirals ties to have an irrational coefficient of “golden section” through the correlation numbers of 1,618… from Fibbonacci series ( 5/3, 8/5, 13/8, 21/13, 34/21, 55/34 …). When the proportion of “golden section” was found in the natural objects since the middle of the 19-th century (A.Zeizing), there began to appear a lot of hypotheses about some special aesthetic and technological characteristics of this proportion. The proportion of “golden section” became the most important architectural instrument in the first half of the 20-th century. This instrument made it possible to design beautiful and comfortable buildings (Le Corbusier). We tried to find a geometric way of building spiral structures which would be similar to natural ones. We solved this problem with the help of the developed algorythm the geometric characteristics of the cells of which spiral structures are built were investigated. It was found out that the cells of “golden” spiral structures don't have any special characteristics if compare with the cells of other spiral structures. During our work we found some spiral structures which have optimal geometric characteristics. These structures let's call them radial-hexagonal, have maximal area of a cell, though they have minimum perimeter. We also defined the main difference in the growing strategy of animate and inanimate structures. Inanimate structures grow by means of addition external elements. Animate structures grow by means of constant pushing of new elements which appear in the centre towards periphery. The optimal filling of the plane in the process of such growing is possible only by “golden section” of “right” and “left” spirals.

title The Meaning of BIM

summary The paper is a position paper, not a report about a research project. It concerns the paradigm-shift that is taking place in the CAAD software and its implications for the business of architecture and more importantly, for the education of future members of the profession. Twenty years ago the use of CAAD software as a replacement for hand drafting was starting. Since then the transformation is complete: hardly a final project in the universities is drawn by hand. Currently, we are witnessing a second paradigm shift and its name is BIM. The meaning of BIM is rooted in two significant differences to current CAAD software and this will have implications for teaching and practicing architecture. The first difference is the way the software structures information in the CAAD file. The standard way to save CAAD information was to organise simple geometric objects according to membership in groups and to sort them according to a layer-metaphor, which primarily controlled the visibility of the geometric elements. Three-dimensional modelling is/was nothing more than the same structure with a more complex geometry. BIM software changes this structure by storing classes of geometries and then to store the specific values of individual geometries according to factors that can be determined by external or internal logical factors. The implication for architects is that we have the chance to be the people in control of the building information model, so long as we invest the time and energy to fully understand what is happening to the building information during the planning process. If we ignore this, the real danger exists that the last control of the building’s final configuration will be usurped. As educators we are currently teaching students that will be leaving the schools in 2012 and beyond. By then, the paradigm-shift will be in full motion and so it behoves us to consider which skill sets we want the next generation of architects to possess. This means not just teaching students about how to use particular BIM software or how to program a certain parametric/genetic algorithm in a form-finding process. We need to teach our students to take the leadership in building information management and that means understanding and controlling how the building information flows, how the methodologies that are used by the consulting engineers affect our building models, and knowing what kind of logical inconsistencies (internal or external) can threaten the design intention.

title A Parametric Shape Grammar of the Traditional Malay Long-Roof Type Houses
source International Journal of Architectural Computing vol. 6 - no. 2, pp. 121-144
summary A parametric shape grammar of the traditional Malay houses (TMH) built in the past century is presented. The grammar, which consists of rules for generating the form and structure of TMH, is derived from simple geometric representations of the houses. The rules first derive the basic unit structures that form the shapes of the TMH. Nine basic shapes have been identified that form the main vocabulary elements of the grammar. Parameterized polygons and lines define each basic shape. Ranges of values assigned to the variables describing the parameterized polygons and lines are presented. The shape addition rules are used to characterize the compositional aspects of TMH style. Evidences of these basic shapes or their combinations have been documented by previous researchers and are used as a way of explaining the built forms of the TMH. The scope of the study is currently limited to the original TMH of the bumbung panjang (long roof) type in which the key features of the houses are easily discernible from the side view.
