title	Multi User Interface Problems in Current CAD Systems
source	Stellingwerff, Martijn and Verbeke, Johan (Eds.), ACCOLADE - Architecture, Collaboration, Design. Delft University Press (DUP Science) / ISBN 90-407-2216-1 / The Netherlands, pp. 183-194 [Book ordering info: m.c.stellingwerff@bk.tudelft.nl]
summary	The general problem of software and hardware interface has been discussed since the first personal computers had appeared on the market. Interface solutions, proposed by the CAD software producers themselves, have been deeply criticised. In fact, learning how to use the software means how to operate its interface. In the process of software developments, interfaces became 'second languages', which are to be learnt by the user. This is a real problem especially for the beginner. The problem is even more complicated in case of interfaces for many users. They should help in the processes of computer networks based cooperative design. In this paper we try to juxtapose the main features of user interfaces in CAD, especially ones for collaborative work. The most important problems were detected, and conclusions were made with an aim to research interfaces adequate for architect's work in the future.

title	Computer-aided Design-based Project Management Model
source	Concordia University (Canada)
summary	The construction industry is one that is fragmented by nature. In current practice, information is exchanged between the designers and contractors in the form of paper documents such as drawings, bills of material and specifications. Information is lost and errors are made during the forward and backward exchange of the design-construction information and constructability knowledge between the design professionals, cost estimators and contractors. Despite the technological developments in IT, the industry has been slow in adopting change in its processes. Computer Integrated Construction (CIC) strives to bridge the gaps of information by integrating the tools and processes within the Architecture, Engineering and Construction industries. This thesis proposes an integrated methodology across the design and construction functions supported by available CAD technologies. The proposed methodology has been implemented in a prototype software application named “CAD-B PM” that allows the user to integrate the CAD design with a central database that is a repository of project information. Productivity and cost estimates are generated within the database and are further integrated to a scheduling application for project planning and control. The prototype system provides a unique solution where the project information is openly shared between the applications in a dynamic environment through the use of Open Database Connectivity (ODBC).

title	Reflections on e-Design: The e-Studio Experience
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	The influence of digital media and information technology on architectural design education and practice is increasingly evident. The practice and learning of architecture is increasingly aided by and dependant on digital media. Digital technologies not only provide new production methods, but also expand our abilities to create, explore, manipulate and compose space. In contemporary design education, there is a continuous demand to deliver new skills in digital media and to rethink architectural design education in the light of the new developments in digital technology. During the academic years 2001-2003, I had the chance to lead the efforts to promote an effective use of digital media for design education at Department of Architecture, Jordan University of Science and Technology (JUST). Architectural curriculum at JUST dedicated much time for teaching computing skills. However, in this curriculum, digital media was taught in the form of "software use" education. In this context, digital media is perceived and used mainly as a presentation tool. Furthermore, Computer Aided Architectural Design and architectural design are taught in separate courses without interactions between the two.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Clients, architects, houses and computers: Experiment and reflection on new roles and relationships in design
doi	https://doi.org/10.52842/conf.acadia.2001.100
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 100-109
summary	This paper reports on recent work that focused on the potential impact of standard computer technology on the relationship between client and architect in the context of residential design. A study of software applications a client could use to develop and evaluate ideas exposed the dearth of software available for the design of spatial complexity by individuals without advanced computer skills, and led to the design of a specific piece of software we call “Space Modeler.” It was prototyped using off-the-shelf virtual reality technology, and tested by a group of freshmen students. The paper discusses the specificities of the software and provides analysis and reflection based on the results of the test, both in terms of design artifacts and users’ comments. The paper concludes that the evolution of the interface to electronic environments is a matter of interest for those concerned with rethinking the training, role and activity of the architect. In the near future prospective homeowners may be able to experience and experiment with the space of their home before it is built. How can the profession embrace new information technology developments and appropriate them for the benefits of society at large?

title	Scheming and Plotting your Way into Architectural Complexity
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	The problem of complexity underlies all design problems. With the advent of CAD however, our ability to truly represent complexity has increased considerably. Following the four waves of design methodology as distinguished by Cross (1984), we see changing architectural design attitudes with respect to complexity. Rather than viewing it as problematic issue, designers such as Koolhaas, van Berkel, Lynn, and Franke embrace complexity and make it a focus in their design work. The computer is an indispensable instrument in this approach. The paper discusses the current state of the art in architectural design positions on complexity and CAAD, and reflects in particular on the role of design representations in this discussion. It is advanced that a number of recent developments are based on an intensified use of design representations such as schema’s, diagrams, and interactive modelling techniques. Within the field of possibilities in this field, the authors discuss Feature-Based Modelling (FBM) as a formalism to represent knowledge of the design. It is demonstrated how the FBM approach can be used to describe graphic representations as used in design, and how other levels and kinds of design knowledge can be incorporated, in particular the less definite qualitative information in the early design phase. The discussion section concludes with an extrapolation of the current role of design representation in the design process, and advances a few positions on the advantage and disadvantage of this role in architectural design.

summary	This paper addresses the recent digital technological advances in design and fabrication and the unprecedented opportunities they created for architectural design and production practices. It investigates the implications of new digital design and fabrication processes enabled by the use of rapid prototyping (RP) and computer-aided manufacturing (CAM) technologies, which offer the production of small-scale models and full-scale building components directly from 3D digital models. It also addresses the development of repetitive non-standardized building systems through digitally controlled variation and serial differentiation, i.e. mass-customization, in contrast to the industrial-age paradigms of prefabrication and mass production. The paper also examines the implications of the recent developments in the architectural application of the latest digital design and fabrication technologies, which offer alternatives to the established understandings of architectural design and production processes and their material and economic constraints. Such critical examination should lead to a revised understanding of the historic relationship between architecture and its means of production.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	A Self-Organizing Neural System for Urban Design
doi	https://doi.org/10.52842/conf.acadia.2001.386
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 386-391
summary	The focus of this research is the development of an urban simulation system and its use to analyze growth factors in an urban design proposal. Unlike predictive simulation models, which attempt to accurately simulate future conditions resulting from a proposal, our neural network model is tuned to creatively present socioeconomic deficiencies and requirements for proposed developments. The system is built using a novel variant of Kohonen’s self-organizing neural map algorithm. Urban data of a simulated region is embedded in the neural net and correlated, in varying degrees, with data obtained from case study and/or other local regions. By projecting design ideas onto this network, designers gain an insight into the proposal’s impact based on complex, non-linear relationships of socio-economic data, which are otherwise difficult to envision.

summary	This paper presents a recently finished course of eight weeks where CAAD skills, design methodology, and architectural theory are combined to discuss possible perspectives on the use of the computer in design, and its influence on architecture. In the course, three contemporary architects were studied; Peter Eisenman, Ben van Berkel, and Greg Lynn. Each was discussed on aspects of ontology (which are the elements of discourse), design method (design process and organization of the process), and the use of the computer (techniques and approaches). These were linked with design theory, architectural theory, and CAD-theory. The reflection on the work of the architects resulted in a number of design methods for each architect. The design methods were adapted to the available technologies in the university as well as to the scope of the exercise, since the period of eight weeks for an exercise cannot compete with design processes in practice that take many participants and much time. The students then applied the design methods to a design task: student housing and an exhibition pavilion on the campus area of the university. The task was so devised, that students could focus on either architectural or urban design level with one of the design methods. Also, the choice of architects and accompanying design methods was made in such a way that students with low, medium, and advanced computer skills could take part in the course and exercise. In a workshop held at the Czech Technical University (CVUT) in Prague, the same procedure was used in a one-week period for a different design task, but in an otherwise almost identical setting with respect to the CAAD software used. The methods and material were easily transferred to the other setting. The students were able to cope with the task and produced surprising results in the short time span available. The paper will provide an overview of the course, discuss the pedagogical implications of the work, and discuss how this particular work can be generalized to incorporate other architects and approaches.

title	Complex shapes in wood: Computer-aided design and manufacture of wood-sandwich roof shells
source	Harvard University
summary	Computer-Aided-Design, Engineering and Manufacturing (CAD/CAE/CAM) technology has changed the way consumer products, automobiles or airplanes are designed and made. The emerging applications for CAD/CAE/CAM technology in architecture, and the way this technology impacts how we design and construct the built environment, are yet unclear. This thesis investigates the relation between advanced digital design tools and the making of physical objects by focusing on an exemplary architectural element—wooden roof shells. The research objective is to expand the scope of architectural design through the application of CAD/CAE/CAM technology rather than to use this technology to streamline existing processes. The thesis develops a specific technical solution that allows the design and manufacture of new types of wooden roof shells. These are complexly shaped multifunctional construction elements that are manufactured off-site. Based on the close connection between digital design tools and the new Computer-Numerically-Controlled manufacturing process the author proposes a theoretical model of shared digital environments for collaborative design in architecture. The proposed manufacturing process treats wood as a modern composite material. Thin wood strips and foams combine into structural sandwich panels that can then be joined into a roof shell. The geometrically complex panels are generated by a combination of subtractive Computer-Numerically-Controlled machining processes and manual work. Infrastructure elements can be embedded into the sandwich build-up in order to enhance the functionality of the roof as a building envelope. Numerical tools are proposed that allow the determination of manufacturing-related parameters in the digital design environment. These inform the architectural and structural design in the early design phases. The digital collaborative design environment is based on a shared parametric solid model and an associated database. This collectively owned, feature-based design model is employed throughout the design and manufacturing process and constitutes the means of concurrent design coordination of all participants. The new manufacturing process for wood/foam sandwich shells is verified by designing and manufacturing prototypes. Design guidelines and a cost estimation are presented as the practical basis for architects and engineers to incorporate new types of roof shells into architectural projects.

summary	Web technology provides a new way of generating information about design processes. By monitoring student use of Web-based design aids, it is possible to collect empirical, quantitative evidence regarding the time and sequence of activities in design. The research team has undertaken several software development projects to explore these concepts. In one project, students can use a Web browser running alongside CAD software to access a cost database and evaluate their designs. In a second project, students use a browser to record their time expenditures. They can better document, plan and predict their time needs for a project and better manage their efforts. In a third project, students record the rationale supporting their design decisions. The information is stored in databases and HTML files and is hyperlinked into the CAD software. Each tool provides facilities to record key information about transactions. Interactions are documented with student identification, time of activity, and kind of activity. The databases of empirical information tracking student activity are a unique substantiation of design process that can feed back into teaching and the creation of ever better design tools.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.

summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

summary	While architects typically agree that daylight is a powerful influence for design, architects rarely collect and use daylighting data to help make informed design decisions. This deficiency exists partially because there are no common tools available to provide useful and accessible data. The objective of this project is to provide accurate daylighting data of a prominent urban building site and present it in a clear way so that the architects can make well informed design decisions that respond to site daylighting conditions and improve architectural performance. An urban 3D computer model was created with AutoCad, a commercial CAD application. Daylight was simulated with Radiance, the physically based rendering engine developed at Lawrence Berkeley National Laboratory. The standard CIE model for clear sky and sun was used to produce over 500 images that represent daylight conditions for three different times of year at 10 minute intervals in both luminance and illuminance formats. The simulation data was packaged for analysis with a unique browser tool that enables the architect to easily cycle through the data to evaluate and compare behavior by time of day and by season. The architect can also toggle between luminance and illuminance format to easily visualize both qualitative and quantitative data. The exploration and use of the simulation data can be applied with sensitivity to inform the design and decision making process for the exterior building site.

title	Evolutionary Algorithms in Urban Planning
source	CORP 2001, Vienna, pp. 269-272
summary	The functions supported by commercial CAD software are drawing, construction and presentation. Until now, no programssupporting the creative part of architectural and urban problem solving are on the market. The grand hopes of symbolic AI ofprogramming creative architectural and urban design have been disappointed. In the meantime, methods called New AI are available.Among these methods, evolutionary algorithms are particularly promising for solving design problems. The paper presents anapproach to town panning and architectural problem solving that combines an evolutionary strategy (ES), a genetic algorithm (GA)and a Particle System. The problem that remains incapable of being solved algorithmically has to do with the fact that in architectureand urbanizm form as well as function count. Because function relates to comfort, easiness of use, and aesthetics as well, it ishopeless to fully specify the fitness function of architecture. The approach presented circumvents a full specification through dividinglabor between the software and its user. The fitness function of town plans is defined in terms only of proportions of the shapes, areasand buildings to be accommodated and topological relations between them. The rest is left to the human designer who interactivelyintervenes in the evolution game as displayed on the screen.

title	Object-Oriented Application Development in CAD
source	Technical Report 48-01-01. Pittsburgh, PA: Carnegie Mellon University, Institute of Complex Engineered Systems
summary	This report describes a graduate interdisciplinary course offered to students in the graduate program of the School of Architecture at Carnegie Mellon and related departments in fall 2000. The motivation was the realization that when commercial CAD (Computer-Aided Design) systems recently switched from procedural application programming languages to object-oriented ones, third-party application must undergo a significant cognitive retooling"; i. e. they must know more than the syntax and semantics of the new programming language to be used and must be able to employ appropriate software development strategies that are appropriate for the new paradigm. especially with respect to the importance of modeling, a distinguishing characteristic of object-oriented programming. The goal of the course was (a) to introduce and test strategies of object-oriented application development in general and in the context of MicroStation, a state-of-the-art commercial CAD package; (b) to develop-as a course team project-an interesting application that gives students practice with these strategies and team work; and (c) to document our approach and findings so that others can learn from them. The strategies introduced were the use-case approach of Jacobson et al. and the complementary object-modeling tools of Rumbaugh that were recently integrated into the Unified Modeling Language UML. The software platform supporting the course comprised MicroStation, JMDL (a superset of Java) and ProjectBank on the CAD side and RationalRose on the modeling side. The application developed by students in the course supports the generation of drawings for remodeling projects from a set of dgn files describing the existing state of the building to be remodeled. The course was supported by a grant and in-kind contributions from Bentley with matching funds from the Pennsylvania Infrastructure Technology Alliance (PITA)."

summary	Similar structures in world-wide architectural education enable a huge global database of teaching elements, filled with copyright-free multimedia-data (digital photographs and videos, 3D-cad-details, . . . ), used by teachers and students worldwide and at any time. This idea is not revolutionary, but the idea must be realised - so this congress will be a catalyst for distributing the idea and to encourage schools and teachers worldwide to feed the database, to use and to improve it!

summary	The history of architecture and its teaching clearly reveal how representations of the image and drawing have changed over centuries. Today, computers are increasingly found at the desks of architecture professionals and students, but their usage remains restricted to technical functions and what is commonly known as CAD (computer-assisted design), in architecture is often simply the other CAD (computer-assisted drawing).This presentation deals with architectural design, particularly at its earliest stage. Our objective is to propose a model for describing the architectural concept that meets the needs of architects through software. Only then will they really be able to use computers as an aid to design by overcoming the obstacles that presently keep us from making full use of them.This has led me to propose an avenue of exploration that examines projection through an object’s properties, and a method of computer-assisted design that makes use of procedural models. These procedural models consist of geometric operators and operators that define the properties, characteristics and performance of a building — operators which I have termed “semantic”.This research fits into a paradigm that leads to representation of the building through functions that can be called with parameters and encapsuled in an algorithm, making it possible to create procedural models that assist with the design. This approach opens up a means of integrating the logos with the figurative representation where drawing is used instead of words to convey the architectural concept.The example of a procedural model shows how we can use a generic model to produce a volume model with all the characteristics belonging to the same family of objects. This type of model can serve not only to illustrate the result of a process, or to draw connections among buildings on the basis of their construction process, or to test the validity of a rule typical of a set of objects, but also to integrate, through a functional language, semantic operators which to date have been excluded from the initial design phase. This descriptive mechanism is extremely powerful in making it possible to establish relationships among the functions and properties of a building and the purpose of the architectural project.The scientific contribution of this research is to test the hypothesis that we can use computer tools to manipulate operators which enable the architect to reappropriate a complex design of the building, and open up new lines of investigation into integrating geometric and knowledge-based systems into a unified representation. The declarative approach for creating three-dimensional scenes fits into this perspective.It is now a matter of exploring the possibility of working on a “common morphology” shared by everyone involved in the design process by rewriting the functions or by converting the functions used for representation, or else through a functional dialect (language) that allows for dialectic relationships among all types of operators and the actions of the protagonists in the architectural design process.
