title The Role of Computers in Synchronous Collaborative Design
source Proceedings of the 14th International Congress on Cybernetics. Namur, Belgium: International Association for Cybernetics, 1995, pp. 71-76
summary In this paper we discuss the role of computers in supporting real-time synchronous design among geographically dispersed team members using the global network of computers known as the Internet. To enable efficient and functional synchronous design activity, we advocate a new generation of design-oriented software that combines collaboration technologies with a meaningful and parsimonious representation scheme. We are particularly interested in supporting the early design phases, wherein many of the most important decisions are made and collaboration is most important. These activities are crucial to the evolution and quality of the final design, and they are receptive to and can benefit from computer support. Furthermore, these are precisely the areas where current CAD systems are weakest. As a general theoretical direction, our emphasis is not on integrated databases, but rather on shared protocols of interaction that are independent of implementation and storage schemes. Our first experimental phase involved the simultaneous development and testing of prototypes for a Synchronous Collaborative Design Environment (SYCODE) on heterogeneous computer systems at two geographically dispersed sites. The applications were developed independently, based on a verbal description of protocols, with minimal sharing of actual source code. Though their user interfaces and implementation details are different, these prototypes allow multiple users to share a virtual design space - both within and between the remote sites - in which to create and manipulate architectural elements.

source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 719-725
summary This research focuses on combining the rich representations of computer-aided design systems with current collaboration technologies to support distributed design processes. Our emphasis is not on concurrent multi-user access to integrated databases, but rather on shared protocols of interaction that are independent of implementation and storage schemes. We have developed a prototype for a Synchronous Collaborative Design System (SYCODE) that enables geographically dispersed designers to share common representations even when using different hardware platforms. The limitations of the existing network infrastructure have compelled its to devise a meaningful and parsimonious representation scheme and to semantically define pending and confirmed actions.

title Geometric programming: A programming approach to geometric design
source ACM Transactions on Graphics
summary This article presents a functional programming approach to geometric design with embedded polyhedral complexes. Its main goals are to show the expressive power of the language as well as its usefulness for geometric design. The language, named PLASM (the Programming LAnguage for Solid Modeling), introduces a very high level approach to "constructive" or "generative" modeling. Geometrical objects are generated by evaluating some suitable language expressions. Because generating expressions can be easily combined, the language also extends the standard variational geometry approach by supporting classes of geometric objects with varying topology and shape. The design language PLASM can be roughly considered as a geometry-oriented extension of a subset of the functional language FL. The language takes a dimension-independent approach to geometry representation and algorithms. In particular it implements an algebraic calculus over embedded polyhedra of any dimension. The generated objects are always geometrically consistent because the validity of geometry is guaranteed at a syntactical level. Such an approach allows one to use a representation scheme which is weaker than those usually adopted in solid modelers, thus encompassing a broader geometric domain, which contains solids, surfaces, and wire-frames, as well as higher-dimensional objects.

title Software design of maintainable knowledge-based systems for building design
source Automation in Construction 4 (2) (1995) pp. 101-110
summary Identifying and establishing a basic structure for knowledge representation is one of the keys to successful design of knowledge-based computer systems. In Building Design and Construction, this initial knowledge structure can be achieved by utilizing a query driven approach to software engineering. As (user) queries reflect the user's demand for in/output, it is natural to link the overall user dialogue with key elements in the knowledge base direct connections between user screen and objects in the knowledge base support prototyping and testing the application during development. However, the price for pursuing this approach in its pure form can be high, as needs for later maintenance and augmentation of the system can be very hard to fulfill. To overcome these problems, a strict user interlace, software separation strategy must be. introduced at early stages of software design. and implemented as a global control module as independent of the knowledge processing as possible.

title Representation, Evaluation and Edition of Feature-based and Constraint- based Design
source Purdue University
summary This thesis investigates a general and systematic approach to feature-based and constraint-based design. We combine feature-based design and constraint-based design by globally decomposing a design into a sequence of feature attachments and locally defining and positioning each feature by constraints. Analogous to the concept of high-level programming languages, we formalize a layered design model that eliminates the dependency of a design representation on a solid modeler. With this design model, design intent, such as feature descriptions and constraints, is stored in an unevaluated, modeler-independent design representation while the geometry to which it corresponds is stored in an evaluated, modeler-dependent design representation. The separation essentially relies on a naming and matching schema that converts between a geometric reference and a generic name, and a design compiler that automatically instantiates the unevaluated design representation to an evaluated design representation with respect to a solid modeler. The geometric references for defining feature attributes and constraints are recorded with their generic names in the unevaluated design representation. We propose several techniques for naming geometric entities unambiguously. The design compilation or instantiation involves remapping a generic name back to a geometric reference in the selected geometric modeler, solving constraints and implementing feature operations or attachments. Instead of developing a constraint solver for this design compiler, we use an independent and general solver. Feature attachment operations are different from classical Boolean operations in solid modeling. However, we provide a semantics for them that is based on existing operations in solid modeling. The layered design model allows users to edit archived conceptual designs to derive new designs quickly. We investigate the coordination of later features in the unevaluated and modeler-independent representation when a feature is edited and provide a method for editing feature-based and constraint-based design. We also discuss how to extend this work to a commercial feature-based and constraint-based CAD system.

title Roof Modeling Using Architectural Semantics Paradigm

summary This paper presents an approach to developing the computer aided architectural design systems investigating architectural semantics paradigm and void modeling representation as a method. A prototypical system called FRED(Facile Roof Editor & Designer) was developed incorporating structural logic and characteristics of roof in its basic representation and its operational behavior constrained by distinct attributes of a roof. Design of Hip, Pitch, Multi-level, and Flat roofs in Solid and Shell forms was made possible by extracting from an existing building or creating them as independent entities. The implementation successfully demonstrates that incorporating architectural semantics in the basic representation of a CAD system allows architects to create and test roof morphology fairly quickly, accurately, and fluidity for ideation.

title An Architecture Model for Multimodal Interfaces with Force Feedback I.14 Virtual Reality 2
source Proceedings of the Sixth International Conference on Human-Computer Interaction 1995 v.I. Human and Future Computing pp. 455-460
summary Multimodal interfaces with force feedback pose new problems both in terms of their design and for hardware and software implementation. The first problem is to design and build force-feedback pointing devices that permit users both to select and manipulate interface objects (windows, menus and icons) and at the same time feel these objects with force and precision through their tactile and kinesthetic senses. The next problem is to model the interface such that it can be returned to the user via force-feedback devices: the task is to define the fields of force corresponding to interface objects and events, and to design algorithms to synthesize these forces in such a way as to provide optimum real-time operation. The final problem concerns the hardware and software architecture to be used to facilitate the integration of this technology with contemporary graphic interfaces. An architecture model for a multimodal interface is presented: it is based on the notion of a multiagent model and breaks down inputs and outputs according to multiple modalities (visual, auditory and haptic). These modalities are represented by independent software components that communicate with one another via a higher-level control agent.

title Patriarch: A Hypermedia Environment for the Support of Architectural Design

doi https://doi.org/10.52842/conf.ecaade.1995.187
summary This paper reports on current research in the field of architectural design and knowledge- based systems, through the conception and implementation of two software tools operating as a part of an integrated hypermedia environment denominated PatriArch. Main concern of this set of tools operating in PatriArch is the support of design since the very beginning, in that phase of not yet correctly explored or interpretated constraints and of scarcely specified goals, in which an initial solution model - provisionally composed of fragments of supposed fitting ideas - for the design theme has to take place. The creative activity of the designer is assumed as an 'intentional planning activity' that represents the acquired level of knowledge of the network of connections defining the nature, function, shape in the space etc. of the increasingly integrated solution-model: the final design will be an evolution of this - and other competitive and concurrent - models. PatriArch is meant to be the environment containing and allowing the representation of this evolution through its ability of linking the fragments of designers' knowledge, supported by an integrated relational data base: Sysinfo. These works were conceived inside an educational software development program for architecture students.

title On the Architecture of a Computer-Mediated Collaborative Product Design Environment
source Intelligent Manufacturing Conference (Ed: S Yang et al) Wuhan, PRC
summary This paper describes the development of a COmputer-Mediated Collaborative Product development Environment (COMCOPE) within the context of the construction industry, a collaborative project between Anglia Polytechnic University, the University of Strathclyde and some industrial partners. The most prominent feature about COMCOPE lies in the particular emphasis on supporting human-human interaction across time and space through computer mediation within a distributed and networked environment. Based on a review of related research areas, traditional computer integrated construction concepts have been extended within the framework of computer supported cooperative work, which results in the COMCOPE conceptual architecture. As the core of COMCOPE architecture an interaction model has been developed to help articulate collaborative activities. Implementation issues have been addressed, and a prototype system, based on an augmented client-server model, has been outlined.

title Applying Formal Methods to Multimedia Design Aid

doi https://doi.org/10.52842/conf.ecaade.1995.283
summary In the last decade we assisted at an evolution of computer aided design systems from drafting, calculation and simulation utilities toward systems able to support the conceptual phase of the design process. Systems supporting conceptual design use knowledge about the design domain and assume a will defined model of the design activity. Their computational framework is usually built by means of a set of representational schemata which lack a formal semantics. This aspect causes a limitation on the applicability of their computational framework to different domains. In this paper we propose a formal knowledge representation language, that has been defined in order to represent the structural relationships of domain knowledge. On the basis of language structure we propose a number of inferences tailored to case-based conceptual design aiding. Finally we apply the representational framework to the implementation of a computational architecture for conceptual design aiding that integrates multimedia representation of design cases with symbolic information processing. The architecture combines a knowledge representation server and a multimedia server. The knowledge representation server processes both domain knowledge and design experiences according to the Case Based Reasoning paradigm. The multimedia server produces the required case representation.

title Drawing Analogies: Finding Visual References By Sketching

doi https://doi.org/10.52842/conf.acadia.1995.035
summary In creative and conceptual designing, architects often look to books, magazines, and other collections of images to find forms they can adopt and adapt in designs. On line visual collections are becoming available but typically they are indexed only with descriptive key words. We argue that in addition to key word indexing, which supports retrieval of images based on design concepts or issues, a more directly visual, graphical reminding scheme based on sketches can help designers recall interesting references from various domains. We describe Drawing Analogies, a shape based reminding program that uses hand drawn sketches to index and query visual databases.

title Hyperwalls or an Application of a Non-deterministic Rule-based System in Interactive Architectural Modelling
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 173-179
summary This paper presents the architectural modeling as a process of augmenting spatial information; a chain of actions that leads from a sketched idea to the elaborated model. A symbolic constraint solver tool is connected to traditional CAD techniques, as well as to a data representation scheme efficient for architectural elements. The orchestration of the available and added tools allows the designer to ěedit ideasî fast, keeping in mind that different design profiles require adaptive tools to support the varying methodologies. Until the moment that automated design will be both possible and desirable, machines can really shorten the time needed to visualize design ideas in the sense of a handy but non-decisive ěcalculatorî. The discussion is built around illustrated examples from the implemented constraint based modeler.

doi https://doi.org/10.52842/conf.ecaade.1995.331
summary Contemporary multimedia research address the possibilities and consequences of integrating various techniques to produce single user based applications (singularity). There is a need for utilising current multimedia techniques; to explore the potential of multi-models (theoretically) to generate modelling information that could be shared simultaneously. The problems are confined to understanding and managing the issues that influence the so-called ´target and product models´. This paper introduces and elaborates on such problems. It provides a theoretical and another practical framework, the 3D-CAD Modelling Paradigm, based upon completed results of modelling. There is a suggested evidence that there might be advantages in standardising the process of modelling and knowledge representation. The paper stresses that the composition of a model should differ from another to reflect its unique characteristics (singularity). Though, it is essential that such models should conform and respond to the well defined and shared criteria (pluralism).

title Interface Design for Building Performance Modeling: Information Representation and Transformation
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 141-152
summary Building design is an integrative endeavor encompassing a multi-variate agenda that deals simultaneously with issues of architectural elements, their attributes (geometry, material properties, etc.), contextual variables (e.g., the uncontrollable external environmental conditions), and building performance variables (e.g., the potentially controllable indoor environment in terms of thermal, acoustical, visual requirements). Ultimately, an important objective of design is to create built environments that are responsive to occupant needs and building performance requirements. This paper will suggest a framework for developing appropriate representations of the complexities involved in building performance simulation. This is based on studies of the communication requirements pertaining to the informational content involved in the design process, and the interfacial relationships between various analytical components as well as between the user and the system. The applicability and effectiveness of this theoretical framework is demonstrated using the example of a fully operational hygro-thermal analysis program (META-4) developed by the authors.

doi https://doi.org/10.52842/conf.ecaade.1995.177
summary Existing computer software to support the teaching of environmental issues to architecture students is mainly based on energy calculation methods or packages of information split into subject areas. Neither approach seems to adequately support the early stages of the design process. The paper explores the construction of a model for a computer based learning system to teach the development of environmental strategies. Different strands of educational theory were used to develop teaching principles based around consideration of the subjective quality of knowledge influenced by ideas and theories from different sources, the importance of learning a "language" consisting of methods and theories of a subject and their application in context and the suggestion that "deep" learning requires conceptual changes. A suitable framework for the development of environmental strategies is suggested and its implementation using multi-media software as a method of integrating different types of information and learning materials is proposed. The paper concludes that the process of analysis is a key part of the system and should be made the focus of the structure and contents.

title Function representation in geometric modeling: concepts, implementation and applications
source The Visual Computer, 11 (8) 429-446
summary Geometric modeling using continuous real functions of several variables is discussed. Modeling concepts include sets of objects, operations and relations. An object is a closed point set of n-dimensional Euclidean space with a defining inequality f x x xn ( , ,..., ) 1 2 0 °ź . Transformations of a defining function are described for the set-theoretic operations, blending, offsetting, bijective mapping, projection, Cartesian product and metamorphosis. Inclusion, point membership and intersection relations are described. In the implemented interactive modeling system, we use highlevel geometric language that provides extendibility of the modeling system by input symbolic descriptions of primitives, operations and predicates. This approach supports combinations of representational styles, including constructive geometry, sweeping, soft objects, voxel-based objects, deformable and other animated objects. Application examples of aesthetic design, collisions simulation, NC machining, range data processing, and 3D texture generation are given.

title Faculties of Architecture
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In order to be inscribed in the European Architect’s register the study program leading to the diploma ‘Architect’ has to meet the criteria of the EC Architect’s Directive (1985). The criteria are enumerated in 11 principles of Article 3 of the Directive. The Advisory Committee, established by the European Council got the task to examine such diplomas in the case some doubts are raised by other Member States. To carry out this task a matrix was designed, as an independent interpreting framework that mediates between the principles of Article 3 and the actual study program of a faculty. Such a tool was needed because of inconsistencies in the list of principles, differences between linguistic versions ofthe Directive, and quantification problems with time, devoted to the principles in the study programs. The core of the matrix, its headings, is a categorisation of the principles on a higher level of abstractionin the form of a taxonomy of domains and corresponding concepts. Filling in the matrix means that each study element of the study programs is analysed according to their content in terms of domains; thesummation of study time devoted to the various domains results in a so-called ‘profile of a faculty’. Judgement of that profile takes place by committee of peers. The domains of the taxonomy are intrinsically the same as the concepts and categories, needed for the description of an architectural design object: the faculties of architecture. This correspondence relates the taxonomy to the field of design theory and philosophy. The taxonomy is an application of Domain theory. This theory,developed by the authors since 1977, takes as a view that the architectural object only can be described fully as an integration of all types of domains. The theory supports the idea of a participatory andinterdisciplinary approach to design, which proved to be awarding both from a scientific and a social point of view. All types of domains have in common that they are measured in three dimensions: form, function and process, connecting the material aspects of the object with its social and proceduralaspects. In the taxonomy the function dimension is emphasised. It will be argued in the paper that the taxonomy is a categorisation following the pragmatistic philosophy of Charles Sanders Peirce. It will bedemonstrated as well that the taxonomy is easy to handle by giving examples of its application in various countries in the last 5 years. The taxonomy proved to be an adequate tool for judgement ofstudy programs and their subsequent improvement, as constituted by the faculties of a Faculty of Architecture. The matrix is described as the result of theoretical reflection and practical application of a matrix, already in use since 1995. The major improvement of the matrix is its direct connection with Peirce’s universal categories and the self-explanatory character of its structure. The connection with Peirce’s categories gave the matrix a more universal character, which enables application in other fieldswhere the term ‘architecture’ is used as a metaphor for artefacts.
