summary	There has been a shift in aesthetics from the modern orthogonal building envelope to more elaborate curved and folded forms. Non_orthogonal forms are often associated with complete freedom of geometry, entrusting the advancement in custom manufacturing and robotic fabrication of one-off building parts to realise the design. This paper presents a methodology that allows non_orthogonal surfaces to be designed using a constrained library of discrete, tessellating parts. The method enables the designer both to produce ‘approximations’ of freeform designs in a top_down manner or to generate ‘candidate’ designs in a bottom_up process. It addresses the challenge in the field of design engineering to generate architectural surfaces which are complex, yet simple and economical to construct. The system relates to the notion that complexity derives from simple parts and simple rules of interaction. Here complexity relates to the holistic understanding of a structure as an interaction between its local parts, global form and visual, as well as functional performance.

title	Over Constrained
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 179-188
summary	Parametric software has fundamentally changed the way in which architecture is conceptualized, developed and even constructed. The ability to assign parameters or numeric variables to specific portions of a project has allowed designers the potential to test variations of their design. Small changes to a single parameter can have an exponential effect on the designed object and alter its appearance beyond original preconceptions in both positive and negative ways. Parametric software also has the ability to constrain or restrict geometry to set values, parameters or conditions. This has the benefit of allowing portions of a form to remain constant or unchanged while simultaneously allowing for a great degree of flexibility in response to a design intent. Constraining portions of a design allows architects to respond to existing or unalterable conditions by ""locking down"" information within a project and then explore those portions that can change more freely. This programmed relationship between the parameter and the form, once established, can give the illusion of minimal effort for maximum output. The ease in which geometrical form can be altered and shaped by a single variable can mislead beginning designers into thinking that the software makes these relationships for them. What is hidden, is the programming or connections needed between the parameters and the geometry in order to produce such dramatic change. Finally, thinking parametrically about design reintroduces the concept of a rigorous, intent driven, fabrication oriented practice; a practice lost in a digital era where the novelty of new tools was sufficient to produce new form. Because parametric models must have established relationships to all parts of the design, each component must have a purpose, be well thought out, and have a direct relationship to a real world object. The introduction of parametric design methodologies into an architectural pedagogy reestablishes architectural praxis in an academic setting. Students are taught to design based on creating relationships to connected components; just as they would do in a professional architectural practice. This paper outlines how Digital Project – a parametric based software – was introduced into an academic setting in an attempt reconnect the ideologies of academia with the practicalities of professional practice. In order to take full advantage of Digital Project as a parameter based software, a project that creates modular, flexible geometries was devised. Produced over one semester, the project set out to find ways of controlling designed geometry through variable parameters that allowed the initial module to be instantiated or replicated into a wall condition: maintaining a unified whole of discrete components. This paper outlines this process, the results and how the outcomes demonstrates the parametric ideologies described above.

title	The Quantum Matrix:A Three Dimensional Data Integration and Collaboration ToolFor Virtual Environments
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	If a picture is worth a thousand words, what if they could walk and talk? How would you like to bring a whole new dimension to your ideas; to use visualization to convey a sense of time and motion, to use imagery to give your ideas vividness; to use sound to give them voice and view them threedimensionally. The Matrix allows you to do all of this and much more. The Matrix resembles Rubik’s cube, but its purpose is to store, manage and access data of all types and to view them in three dimensions in virtual environments such as the CAVE and on your desktop. The current version can store, access and view almost anything that is in digital form, including:Text files Pictures Video Clips Sound Files Spreadsheets URL’s HTML pages Databases CAD drawings Gantt Charts Business Graphics VRML modelsExecutable Programs OLE (Object Link & Embedded) The Matrix is a three-dimensional multimedia and document management tool. The Matrix anticipates the convergence of electronic media into one consistent environment for analysis and representation. the Matrix uses VMRL and OpenGL technologies to allow the user to be immersed in their data as withCinerama, IMAX and Virtual Reality Environments. The Matrix allows the user to exercise their creativity by interactively placing and organizing their data three dimensionally and navigating through and viewingdata and documents in 3D (monocular and binocular – stereo). The Matrix user interface is simple to use. Employing the now familiar “drag and drop” method to manage data and documents. Items can be placed into the matrix grid at a user selected matrix cube location. Upon dropping a document on a cube it appears as a mapped image onto the surface. Navigating through the 3D Matrix-space is fun. All navigation uses real-time animation giving you instant feed back as to where you are. Data drilling is as simple as mouse click on a Matrix cube. Double clicking the on an object in the matrix activates that object. Data dreams was an image that preexisted the program by several years. The dream was to create a new way oforganizing and exploring data. The Qube image was created using Microstation by Bentley Systems, Inc. The figure was modeled using Poser by MetaCreations and composited using Adobe Photoshop.

summary	The goal of the presented research is to explore human-machine interaction and to study how Augmented Reality (AR) may be a potential tool to inform Architectural Rehabilitation and Conservation processes. Nowadays obtaining data to inform both marchitecture projects and real estate investments is a very bureaucratic process. City councils technicians suffers from the same diffi culties when are in fi eldwork to do inspections and lack a complete sort of information. This proposal considers that the use of mobile technologies as smart phones and tablets can empower these technicians to obtain building related data. The specifi c goal of the study aims to develop a data model and an interface that can be made available to professionals which allows an efficiently reply to the user’s needs as the system enables the gathering of updated information considering a particular building.

title	A Spatial Relational Reference Model (3RM)
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 85-91
summary	In this chapter we hope to provide the reader with an impression of the objective, framework and possibilities of 3RM in the construction industry. In Dutch, 3RM stands for 'Ruimtelijk Relationeel Referentie Model' (Spatial Relational Reference Model). The model could begin to be used as an information-bearer in the building industry within which the specific trade information for each of the building participants could be interrelated, including drafting symbolism, building costs, physical qualities and building regulations. In this way, the model can be used as a means to a more efficient running of the building process and enabling the integration of information, at project level, provided by various building participants. The project should be defined in the same way as is a typical architectural project, whereby the actual development as well as the project management is carried out by architects. For the time being, development is limited to integral use at the design stage, but it also offers sufficient expansion possibilities to be able to function as a new communications model throughout the complete building process. We shall first provide information as to the origin, the objective and the execution of the project. Thereafter, we shall attempt to state the theoretical information problem within the building industry and the solution to this offered through 3RM. Finally, we shall report upon the results of the first phase of the 3RM project.

title	Exploring motion sequence of virtual characters: Experimenting motion-capture variables
source	Proceedings of the 2nd International Conference on Geometric Modelling and Imaging (GMAI 07), ETH Zurich, Switzerland, 4-6 July, 91-96.
summary	The purpose of the research is to study the detail of motion of various subjects with differences in physical attributes. The research outlines how different physique produces different behavioural patterns based upon mass and proportion. This research focuses on ‘walk motion’ to identify the differences in each subject’s physical attributes by sampling subjects of physical differences. This experiment employs Vicon8i® Optical Motion Capture system (MOCAP) to study the detail of human motion by extracting the subjects’ core motions for analysis with pre-defined actions. The research used the findings to establish the relationship between height and weight against motion frequencies in 3D space.

title	From Research to Practice [Conference Proceedings]

doi	https://doi.org/10.52842/conf.acadia.1990
summary	For the tenth time in as many years, the Association for Computer-Aided Design in Architecture (ACADIA) has invited architectural educators and professionals to discuss their activities and interests related to computer-aided architectural design. This annual meeting has grown from a small group representing a handful of schools to a conference with international participation. For the fifth time, the papers presented at this annual conference have been collected and published in a bound volume as the conference proceedings. In organizing these meetings, ACADIA must be viewed has having firmly established itself as a valuable forum for those who are interested and active in this area. Moreover, the proceedings of these conferences have become an important record for documenting the progress of ideas and activities in this field. This organization and its annual conferences have been a critical influence on my own professional development. The first conference I attended, ACADIA '86, confirmed a nagging suspicion that courses in computer-aided design (CAD) offered at the university level should be more than vendor training. Papers and conversations at subsequent conferences have reinforced this conviction and strengthened my commitment to CAD education which does more than convey electronic drawing technology. At the same time, I have been frustrated at the apparent lack of communication between those involved in these activities in architectural education and the average professional practice. With some notable exceptions, architects are only beginning to make basic computer-aided drafting pay for itself. In many small offices, "The CAD Computer" remains more decoration and status symbol than useful tool. While it can be argued that the economics of computer-aided drafting have only recently become attractive, it must be admitted that many members of ACADIA are actively involved in the development and use of computer applications which are significantly more challenging. In the short run, most of these activities will go largely unnoticed by the community of practicing architects. This situation raises a number of questions on the value of the work produced by members of ACADIA. One can (and many do) challenge the worth of "design" research produced by academia to those in professional practice. However, it is a fundamental mistake to insist that such work be of immediate and direct relevance to the profession. In fact, some presentations at the ACADIA conferences have focused solely on the pedagogical environment (which may be of some intellectual interest) but do not even attempt to address professional design issues. Other work may serve as the basis for further activities which may result in useful applications at some future point in time. Such work is strategic in nature and should not be expected to bear fruit for many years. These are the *natural" products of a university environment and, indeed, may be what the university does best. Still, design professionals remain indifferent (if not somewhat hostile) to these endeavors. The central dilemma resides in the ongoing debate about the fundamental goals of professional education. A number of design professionals believe that architectural education should follow more of a “trade school” model where a professional degree program becomes solely a process of acquiring (and practicing) a set of skills which are directly and immediately useful upon graduation. Today these people stiR closely examine the drafting skill of any recent graduate, but they are also likely to demanding expertise on AutoCAD. It is my view that this position tends to deprecate the image of architects and depreciate the economic status of the profession. On the other hand, there is a similar minority in architectural academia who teach because they are unable or unwilling to deal with the very real complexities and challenges of professional practice. These instructors tend to focus on obscure theory and academic credentials while discounting the importance of professional development. For most who participate in this discussion, it is becoming increasingly clear that professional competency must be founded on an effective marriage of intellectual theory and practical expertise. This must lead to the conclusion that CAD research must recognize and give serious consideration to the professional agenda in a substantive manner without abandoning those activities which deal with strategic and pedagogical issues.

summary	There is a significant variance in the way computer courses are taught at various institutions around the country. Generally, it is useful to think of these courses falling either into a "tool-building" or a "tool-using" category. However, within either category, there is a variety of focus on the application of the "tool". Two courses have been developed at the University of Hawaii at Manoa which deal with computer applications. The first course is more quantitatively oriented, encouraging students to explore ways of dealing with problems in a more complex and substantial manner. This paper deals with the second course whose focus has shifted toward design issues, using the computer as a tool to explore these issues. This course exposes the student, not to training on a specific computer-aided drafting system, but to issues in computer-aided design which include hardware and software systems, human-machine interface, and the nature of the design process. This course seems to be an appropriate model for introducing computer-aided design to undergraduates in a professional design program.

title	The Management of CADD Systems in the AEC Office
source	1985. [17] p
summary	A well known A/E firm purchased a CAAD system two years ago. They report great success and satisfaction. Their staff is enthused and more importantly so are their clients. Other firms watched them, and after six months one of their competitors purchased the identical CADD system. But that's where the similarities end. At the second firm, the system is under-utilized, management and staff appear to regret their decision and there has been little impact on the firm's work, its profitability and its clients. Identical systems installed in very similar firms with totally different results. What's the difference? MANAGEMENT...Even with the brief history of CADD in the AEC office we can see that the success or failure of CADD system implementation is more likely traced to the effectiveness of management than accuracy of system selection. The information conveyed in this paper is directed at new and experienced planners and managers of turnkey CADD systems in AEC or facilities management environments. With a focus on real solutions to real problems, it addresses some of the critical issues that will help you successfully plan and implements your own CADD system

summary	We have been witnessing an increased interest in a more holistic approach to urban design practice and education. In this paper we present a spatial data model for urban design that proposes the combination of urban environment feature classes with design process feature classes. This data model is implemented in a spatial database that becomes the backbone of a City Information Model (CIM), integrating urban neighbourhood formulation, design, and evaluation methods into a comprehensive urban design support system. We demonstrate its application to urban design analysis and evaluation through the development of a tool for AutoCAD Map 3D that is integrated with the PostGIS spatial database.

summary	The healthcare building design process involves complex decision-making, considering both normative restrictions and other essential program qualities. To address this challenge, a BIM framework is proposed, providing multi-criteria evaluations for architects at various design stages. The framework uses semantic modules to measure the BIM model and compare results with reference goals, including restrictive norms. Employing Design Science Research, existing evaluation modules were integrated. The current implementation includes normative checks, indoor environmental quality, and spatial syntax indicators analysis. The contribution lies in offering a tool that optimizes the healthcare building design process by providing visual feedback for the users, who are designers and regulatory bodies.

title	A Regionalist Approach to Generative Design Process: From Concept to BIM Model
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 1097–1108
summary	This paper presents the implementation of two generative computational architectural design systems integrating regionalist inputs. While the automation of the design process using computational tools has been extensively discussed, the incorporation of regionalism remains limited. To address this, the Design Science Research method was employed to create computerized artifacts generating architectural models in BIM associated to Visual Programming Languages. The innovation lies in considering materiality requirements, building systems, and regional aesthetics as primary inputs for generating parametric shapes. The framework enables the generation of detailed BIM models, automatically documenting them to comply with local construction norms. This paper provides insights into the functionality of the generative algorithms, showcases the produced architectural instances, and presents the automatically generated 2D documentation. Additionally, a framework for a regionalist computational design approach is proposed. The study highlights the importance of incorporating regionalism and provides a foundation for the development of similar artifacts.

summary	The feedback-loops of the modern architectural design practice are broken, as architects rarely get to experience and learn about life in their buildings in a systematic way. Through novel survey and annotation methods, this project aims to develop tools and methodologies that assist architects in getting insights into the built environment. This paper describes the initial development of a framework for surveying and annotating occupant behaviour within architecture, called "Behavioural Situations". Using object recognition on embedded devices, it is possible to build an understanding of occupant behaviour, by coupling behavioural signifiers and their relations as nodes and edges in a graph representation.

summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

summary	This paper aims to analyze interactive multimedia and visualization techniques for architectural theory publications. Unfortunately, the available literature about multimedia, visualization, hypertext and related systems in this area is not consistent. The paper reviews the features of a research project outcome, which investigates an iconic building of the late 1930’s in Brazil. It examines the differences and similarities between a hypertext/multimedia system – a CD-ROM – with a comparable non-hypertext or non-computer product – a book – that deals with a specific subject: Architectural Theory.

title	Designing Shelters for 3D-printing - A studio experiment

summary	This paper describes an architectural design studio experiment, developed with the aim of exploring the interrelationship between the architectural design of basic shelters and additive manufacturing technology (aka 3D printing) using concrete. This fabrication technology has been developed over the past twenty years in various locations Worldwide and there has been some experiments on its use for making buildings. However, these experiments are still very limited in number and results, in the sense that do not fully explore the potential of the technology and its impact on the way we design and make buildings. The studio evolved in the context of a larger project in which a multidisciplinary team of researchers is developing the technology for the additive manufacturing in concrete. Research evolves along three main thrusts of work on materials, systems, and design. The studio introduced students to these various aspects, examined their interrelationships, impacts, and applications in architectural design and construction of buildings. The hope was to collect more information and feedback to inform the overarching research. Results showed the feasibility of the technology and identified issues that need to be addressed in future research.

title	MASS CUSTOMIZING PREFABRICATED MODULAR HOUSING BY INTERNET-AIDED DESIGN

summary	By collecting and evaluating client’s requirements with web technology, a methodology can be developed that can generate design options based on the client’s needs and available modular components in the market, and simulate the final design before beginning manufacturing. In this proposed model, a process of providing mass-customized prefabricated housing based on computer-aided design and a web-based product configuration system will be presented. How prefabricated housing design can be evolved from a mass repetitive production level to a mass customization level to meet variability and personality is the primary issue to be explored in this research.
