summary	Combining CAD and GPS in architecture is a challenging task. Both technologies have not much in common. While GPS is used for mapping, CAD is used for modeling and virtual constructing. The request to design an application, the AmbiViewer, which can be used as design tool in an outdoor environment, brought the technologies together. This paper gives an overview about the GPS-technology and the integration into the modeling software.).

title	Portable Generative Design for CAD Applications
doi	https://doi.org/10.52842/conf.acadia.2011.196
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 196-203
summary	Most CAD applications provide programming languages for automation and generative design. However, programs written in these languages are not portable because they execute only in the family of CAD applications for which they were originally written. Consequently, users are locked-in to one family of CAD applications and they cannot reuse programs written for other families. In this paper, we propose a solution to this problem: Rosetta, a programming environment that is compatible with several CAD applications. Rosetta is composed of (1) an abstraction layer that allows portable and transparent access to several different CAD applications; (2) back-ends that translate the abstraction layer into different CAD applications; (3) front-end programming languages in which users write the generative design programs; and (4) an intermediate programming language that encompasses the language constructs essential for geometric modeling and that is used as a compilation target for the front-ends.Rosetta allows users to explore different front-ends and back-ends, in order to find a combination that is most suitable for the problem at hand. As a result, users have access to different programming languages, namely, visual and textual, which can be used interchangeably to write generative design programs, without breaking portability. Furthermore, Rosetta ensures that a single program can be used to create identical geometric models in different CAD applications. This approach promotes the development of programs that are portable across the most used CAD applications, thus facilitating the dissemination of the programs and of the underlying ideas.

title	Keepers of the Geometry: Architects in a Culture of Simulation

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.

title	Computational Modeling and Controlled Free-fall Stacking Strategies of Star-shaped Particles for Aggregate Structures
source	Dagmar Reinhardt, Nicolas Rogeau, Christiane M. Herr, Anastasia Globa, Jielin Chen, Taro Narahara (eds.), ARCHITECTURAL INFORMATICS - Proceedings of the 30th CAADRIA Conference, Tokyo, 22-29 March 2025, Volume 2, pp. 429–438
summary	This study investigates the stability of granular stacking in architectural design by exploring how particle geometry and deposition methods affect structural performance. Addressing the challenge of creating cohesive structures with non-cohesive particles, four star-shaped particles (Tetrapod, Hexapod, Octapod, and Dodecapod) were tested under two stacking strategies: layered arrangement stacking (LAS) and randomly arranged stacking (RAS). Simulations modeled columns, walls, cantilevers, and arches to assess interlocking effects and stability. Results demonstrate that RAS achieves stronger interlocking and greater stability, particularly in complex forms, while LAS provides enhanced control through staged particle drops, allowing gradual settlement layer by layer. A custom computational component was developed to precisely control particle drop positions and sequences, integrating with the FlexHopper simulation engine to simulate realistic stacking behaviors. These simulations were validated against physical prototypes, showing a close alignment between digital and physical outcomes. This research introduces a method for controlled free-fall stacking that expands the potential of granular materials in architectural applications, enabling the design of innovative and adaptable aggregate structures.

summary	One of the most important natural resources for the urban sustainability is water. For this reason, the incorporation of appropriate strategies to manage water resources from buildings and urban planning is necessary. In this work a series of parametric criteria are defined, with which by using design software it proposed generating optimal forms in certain scenarios for high hydric performance in urban residential complexes. The examples developed demonstrates strong influences of dwelling density by the construction block and permeable outdoor surfaces, as well as local infrastructure for water recovering.

title	A cooperative model using semantic works dedicated to architectural design
doi	https://doi.org/10.52842/conf.caadria.2005.094
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 94-104
summary	Architectural cooperative design as well as information modeling have been active research areas for several decades. The use of systems adapted to the cooperative design assistance for the building domain is complex. This results from the complexity of the cooperative work (difficulties in tracking actor’s work, lack of most of the required information, coordination problems, implicit nature of most of the construction activities, etc.) The main objective of our research in these domains is to develop a tool that helps the management of a building project and aids cooperative design. So, in the first part of this article, we propose to view the exchanging data mode and cooperation tools in the building domain. The second part of this article illustrates the existing cooperative design models. Then we justify the interest shown in a new model of cooperative design where the relational organization of the project and the semantic meaning of works are taken into account. Finally, we use this new model for defining a design-aided tool, to deduce advantages and limits of the “Virtual Cooperative Project”.

summary	The use of informatic tools (computer-aided design) may be associated to designer tasks since the first phase of product conception until industrial production. By using these CAD tools during the initial design phase, it is possible to predict, identify and correct mistakes. This is an interdisciplinary article that presents and discusses an experience as a teacher of graphics computation II, offered to product design students. It also reveals the didactic methods and psychological approaches applied to address this challenge: Achievement motivation, pedagogy of autonomy and learning pyramid. The didactic experiment was positive and lead to interesting learning results.

title	Generative tool to support architectural design decision of earthbag building domes
source	SIGraDi 2017 [Proceedings of the 21th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-227-439-5] Chile, Concepción 22 - 24 November 2017, pp.584-589
summary	The interest in earthbag dome construction (also known as sandbag, superadobe or superblock construction) is increasing as a world consciousness develops to achieve the planet’s equilibrium for sustainable living. The main objective of this research is to develop a parametric tool to help architects modeling virtual earthbag domes from ideation to construction phase. This challenge has been addressed by adopting an experimental methodology that explores parametric generative design with the use of visual programming language (VPL). In this paper we present the development of a tool for the ideation level including features that allow for the calculation of material quantification. The usability of the tool was validated by earthbag constructors and architects.

title	Programmatic Formation: Practical Applications of Parametric Design
source	International Journal of Architectural Computing vol. 7 - no. 4, 587-604
summary	Programmatic Formation explores design as a responsive process. The study we present engages the complexity of the surroundings using parametric and generative design methods. It illustrates that responsiveness of designs can be achieved beyond geometric explorations. The parametric models can combine and respond simultaneously to design and its programmatic factors, such as performance-sensitive design-decisions, and constraints. We demonstrate this through a series of case studies for a housing tower. The studies explore the extent to which non-spatial parameters can be incorporated into spatial parametric dependencies in design. The results apply digital design and modeling, common to the curriculum of architecture schools, to the practical realm of building design and city planning. While practitioners are often slow to include contemporary design and planning methods into their daily work, the research illustrates how the incorporation of skills and knowledge acquired as part of university education can be effectively incorporated into everyday design and planning.

source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 331-350
summary	The use of computer tools in architectural practice has been steadily increasing in recent years. Many architectural offices are already using computer tools, mostly for production tasks. Hardly any design is being done with the computer. With the new computer tools, architects are confronted with the challenge to use computers to express their design ideas right from conception. This paper describes a project made for a competition which recently took place in Spain. Sketches and computer models were the only tools used in designing this project. A variety of computer tools were used in different stages of this project: two dimensional drawing tools were used in the early stages, then a three-dimensional modeling program for the development of the design and for the production of final drawings, and a rendering program for final presentation images.

summary	In the early stages of their engagement of computer technology, architects approached the technology as an assistive technology that would enhance the practice of architecture. The scope of the engagement was captured in the phrase ‘computer-aided architectural design.’ In the four decades since, the role of computer technology in architecture has gained a marked significance. The scope has now been extended for architects to contemplate ‘totally computer-mediated architectural design.’ The key in the development of digital tools to enhance the practice of architecture has been the facility with which the various tasks involved in the practice of architecture have been represented, enabled or enhanced using computer technology. Tools have always been created for their instrumentality, that is, their ability to assist in performing desired tasks. Given the scope of the engagement of computer technology by architects in the early phases, the assistive nature of tools formed the focus of researchers. The focus on this assistive nature has continued to remain in the minds of researchers who see assistance as the proper role of computer technology in architecture.

summary	Auditorium design is a complex task. Various programmatic, functional and acoustical parameters have to be resolved in the spatial design of an auditorium. This ongoing research project deals with the development of a computer-aided design system for the preliminary spatial design of proscenium type auditoriums. The concept of “acoustic sculpting” is used to generate the spatial form of the auditorium from programmatic, functional and acoustical parameters. These parameters are incorporated using a combination of mathematical, empirical and statistical methods. The generation of the spatial form of the auditorium is implemented as an algorithm that is executed on the computer. The spatial form of the auditorium generated by the system is exported as a computer model for design development and acoustical analysis.

summary	Computational building performance modeling typically generates large amounts of data. For this data to become operative information, i.e., provide effective feedback to the design process, it must adequately interface with the informational requirements and procedural characteristics of the building delivery process. Toward this end, this paper specifically addresses the potential of aggregate space-time performance indicators.

summary	Programming, often called scripting, has become a key feature in most CAD systems and an equally key area of expertise in CAD. However, programming surrenders many of the benefits of direct manipulation and introduces notational elements that are cognitively distant from the designs being created. In addition, it creates barriers to use and is often perceived as being too difficult to apply. We introduce Programming In the Model (PIM) through a prototype, implementing live side-by-side views, multi-view brushing and highlighting, live scripting, auto- translating from modeling operations to script and localized relational information within model windows. A qualitative user study confirms PIM’s features and raises issues for future development. A key result is the need for multi-directional extreme liveness , that is, maintaining consistency of action across views at the smallest possible scale. We argue that PIM principles are applicable in textual and visual programming alike.

summary	The countries of the Gulf Cooperation Council have, in recent years, undertaken several initiatives to make sustainability central to their urban agendas. This research aims to operationalize the concept of sustainable development – environmental, economic and socio-cultural – in the region, and develop parameters that define it. Using native neighborhoods in Abu Dhabi as a case study, it focuses on the development process of a computational toolkit which has two major components – a quantitative toolkit which contains modules for simulation of aspects of environmental and economic sustainability, and a spatial toolkit which contains modules for simulation of socio-spatial practices associated with the specific social and cultural context. One of the primary needs of these communities, identified through an extensive review of literature and through conversations with Emiratis, is that of visual and acoustical privacy. Privacy from neighbors and passers-by, externally, and between genders, internally within the house. Using this as a starting point, this paper describes the development process of a module that aims to measure levels of external visual privacy of surfaces at a housing plot level, from neighbors and passers-by. The first section of the paper establishes the context of the research. The second section focuses on describing the process of modeling built form and testing it for visibility and thus, privacy.
