summary McIntosh, in ACADIA Newsletter Vol. 9 No. 3 pp 20-23, June 1990. This book introduces the concept of modeling objects in the computer's memory so it can be used to aide the process of their design. Modeling is defined as an hierarchical abstraction of data and operators to manipulate it, subject to semantic integrity constraints that guarantee the realizability of the designed artifact in the real world. Starting with general concepts of modeling, the book moves on to discuss the modeling of shapes (form) in two and in three dimensions. The discussion covers both topology and geometry. Next the book introduces the concept of shape transformations (translation, scaling, rotation, etc.), both in absolute and in relative terms. The book then introduces the concept of assembly modeling, and adds non-graphical attributes to the representation. It concludes with a discussion on user interface and parametrization. The book includes many examples written in Pascal that complement the theory, and can be used as a basis for building a geometric modeling engine. It also includes exercises, so it can be used as a text book for a two-semester advance course in geometric modeling

summary Computation in design has long been a focus in our department. In recent years our faculty has paid particular attention to the use of computation in professional architectural education. The result is a shared vision of computers in the curriculum [Woodbury 1985] and a set of courses, some with considerable historyland others just now being initiated. We (Dave and Woodbury) have jointly developed and at various times over the last seven years have taught Computer Modeling, the most introductory of these courses. This is a required course for all the incoming freshmen students in the department. In this paper we describe Computer Modeling: its context, the issues and topics it addresses, the tasks it requires of students, and the questions and opportunities that it raises. Computer Modeling is a course about concepts, about ways of explicitly understanding design and its relation to computation. Procedural skills and algorithmic problem solving techniques are given only secondary emphasis. In essential terms, the course is about models, of design processes, of designed objects, of computation and of computational design. Its lessons are intended to communicate a structure of such models to students and through this structure to demonstrate a relationship between computation and design. It is hoped that this structure can be used as a framework, around which students can continue to develop an understanding of computers in design.

title Archaeological Site Reconstruction With AutoDesk's 3D Studio
source CSA Newsletter Vol 7:3 Nov 1994
summary 3D Studio is an IBM-compatible computer modeling program that enables users to create three-dimensional renderings of a variety of objects. In its ability to import a wide variety of maps and other images, 3D Studio allows for the realistic rendering of models created within AutoCAD or other 3D CAD packages. Over the past year, the Homol'ovi research program has been utilizing this software to create near photo-realistic renderings of conjectural site models. My own interests in three-dimensional computer modeling developed out of work at the site of Homol'ovi IV, a 150-room pueblo site located near Winslow, Arizona. The site was situated upon a steep 30-meter bluff with a bedrock cap. Approximately 24 rooms were located on top of the bedrock cap, with another 125 rooms situated on the slope of the butte. During the 1989 field season five structures were excavated, while a separate crew worked clearing and mapping the tops of walls. Mapping was accomplished with a Topcon EDM/theodolite station, and a standard map was created from this process. (See Fig. 3.) While the map was sufficient to show the general layout of the site, I remained unsatisfied; a 2D plan view simply did not convey the vertical dimension of the pueblo. At this point the Homol'ovi Research Program purchased a copy of AutoCAD in order to begin exploring three-dimensional mapping and modeling.

title Geometric and Solid Modeling
source Morgan Kaufmann
summary Solid modeling is rapidly emerging as a central area of research and de- velopment in such diverse applications as engineering and product design, computer-aided manufacturing, electronic prototyping, o -line robot pro- gramming, and motion planning. All these applications require represent- ing the shapes of solid physical objects, and such representations and basic operations on them can be provided by solid modeling. As a eld, solid modeling spans several disciplines, including mathemat- ics, computer science, and engineering. In consequence, it is a broad subject that must accommodate a diversity of viewpoints and has to meet a diversity of goals. Sometimes, this diversity of goals can lead to con icting demands. Current thinking on the subject views the proper resolution of these con- icts to be application-dependent. That is, it is no longer thought realistic to envision a comprehensive solid-modeling system that satis es the needs of all potential users. Rather, as it is argued, we should concentrate on con- structing a software environment in which many tools for geometric and solid computation are available and can be combined with ease as appropriate for the speci c application under consideration.

summary Computing impacts the preliminary architectural design process as a tool for observation and analysis, as a formal prototyping tool, and as a vehicle to generate variations of objects and assemblies. Through the use of both traditional and computing tools, the Form Processing Workshop examines the relationship between design decisions and design tools. The Workshop utilizes several software applications, with emphasis on the use of a solid modeler. This curriculum was developed with the support of MIT's Project Athena.

title A Programming Language for Architectural Symbolic Modeling
doi https://doi.org/10.52842/conf.ecaade.1989.x.r3e
source CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 8.4.1-8.4.16
summary In this paper a software project supporting architectural design is outlined. Such a project aims to develop the new design language PLASM (a Programming Language for Architectural Symbolic Modeling), which is planned to be a very high-level, user-oriented language, belonging to the class of constraint languages. The language PLASM will support a small set of abstract data types which are significant in various outstanding problems of architectural design, and will offer both procedural features and non-procedural constraints satisfaction. It will allow the designer to make use of a large set of computing tools in any phase of architectural design, in order to explore a wider set of design solutions. Customizable evaluation functions will be available in the language. The execution of a PLASM program may result either in generating or in updating a semantic network over a set of data objects solving the geometric problem under consideration. The proposed language will support both abstract data types significant in the design domain, and tools performing automatized data generation and transformations between different data types. The modification of any object in such a system, both performed by editing a daemon program and/or by interactively modifying a data object, will result in the immediate propagation of changes into the problem network, by activating a message passing mechanism.

title Theory and Practice of Geometric Modeling
source Springer-Verlag
summary This book originates from the lectures given at the international conference "Theory and Practice of Geometric Modeling", Blaubeuren, FRG, October 3-7, 1988, that brought together leading experts from universities, system developers, and system users, to discuss new concepts and future trends in geometric modeling. The book covers a variety of topics on an advanced level and is organized as follows. Part A contains new algorithms and techniques for modeling objects that are bounded by free form surfaces. Part B focuses on surface/surface intersections, new types of blending surfaces and speed ups for ray tracing. Part C contains some new geometric tools. Part D discusses different representation schemes in solid modeling, conversions between these different schemes, and some applications. Part E covers some issues of product modeling, automatic tolerancing, high level specification of solid models (constraints, features) and the need for better user interfaces.

title Intelligent CAD
source North-Holland, Amsterdam, pp. vii-ix
summary In this research, design process knowledge is represented at two different levels, action level and object level, corresponding to the meta-knowledge to model design behaviors and the special knowledge to model the processes in designing particular objects. A design knowledge base and database modeling language - Integrated Data Description Language (IDDL) was developed at the University of Tokyo to model both design processes and design objects. This language combines logic programming functions and object oriented programming functions into an integrated environment. Using this language, an intelligent CAD system - Intelligent Integrated Interactive CAD (IIICAD) was developed at the University of Tokyo. Contradictions of knowledge base and database are resolved using circumscription and Assumption-based Truth Maintenance System (ATMS) in this system. Many advanced knowledge modeling techniques, including Qualitative Process Theory (QPT), modal logic, default reasoning, etc., have also been introduced in the IIICAD system. The knowledge base and database representation scheme of IDDL serves as the basis in the feature-based integrated concurrent design system. In the integrated concurrent design system, a new feature modeling language was introduced. In addition to the qualitative and quantitative data/relations that were introduced in IDDL, the composing element features, data dependency relations, constraints, 2D and 3D feature geometric descriptions have also been introduced for representing product life-cycle models and their relations. Optimization functions were added to the integrated concurrent design system to identify the optimal design considering relevant life-cycle aspects.

source New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 103-130
summary Replacement operations, where an element at any topological level may be replaced by another element at the same or different topological level, are defined. Their potential as design tools which may be incorporated in a CAD system is investigated and demonstrated through the experimental implementation of two such operations in MARCOS, a Modeling Architectural Compositions System. MARCOS has been written in C. It is highly interactive and runs on an Apple Macintosh IIx. The two operations which have been implemented are the face -> volume and volume -> volume replacements. They were chosen for their potential as generators of architectural forms. Examples of architectural compositions produced through the use of replacement operations are also illustrated.

title Modeling the Emergence of Schemas in Design Reasoning
source Design Computing Unit, Department of Architectural and Design Science, University of Sydney, 1989. pp. 173-205. CADLINE has abstract only
summary The authors explore how neural networks can be used to model important aspects of design reasoning: the way design involves memory; and a 'holistic' kind of reasoning by which designs appear to emerge from that memory. A simple neural network is constructed to demonstrate how information about schemas (in this case, room types) is stored implicitly after exposure to a number of examples of specific rooms. We then demonstrate how new room types emerge from this information. The paper includes a discussion of design, a discussion of schemas from a psycholinguistic perspective, a technical explanation of neural networks and the demonstration of an implemented examples

title Boundary Evaluation in a Non-Manifold Environment
source November, 1989. 30 p., [16] p. of ill. includes bibliography
summary The recent availability of Non-Manifold Topology (NMT) enables the coexistence of wireframe geometry, surfaces, and solids in a single representation with complete topological resolution. This in turn allows a new approach to boundary evaluation. This new approach merges a set of primitives into a single Boundary REPresentation (B-rep), and selects the desired Boolean results without destroying any B-rep entities. The results of the Boolean operations are displayed by drawing only selected entities. The B-rep resulting from the merge contains a complete description of the input primitives. While traditional algorithms allow incremental addition of primitives, this new approach also allows incremental deletion of primitives from the merged B-rep. Changes in Boolean operators and/or their order of evaluation can be reflected in the B-rep simply by changing the criteria of the selection process. Constructive Solid Geometry (CSG) editing operations can be mirrored in the B-rep incrementally, i.e. without performing complete reevaluation of the B-rep from its constituent primitive definitions. In addition, the domain of boundary evaluation has been extended to include Boolean operations between wireframe geometry, surfaces, and solids. This new approach has been successfully implemented and tested to boundary evaluation. Test results have shown an order of magnitude reduction in the cost associated with reflecting CSG editing operations on existing B-reps, with only minimal additional cost for initial construction. Also shown are examples of Boolean operations between solids, surfaces, and wires

summary While the development of modeling and drafting tools for computer-aided design has reached a state of considerable maturity, computerized decision support in architectural sketch design is still in its infancy after more than 20 years. The paper analyzes the difficulties of developing computer tools for architectural problem solving in the early stages of design where decisions of major importance are made. The potentials of computer methods are discussed in relation to design as a static system of information and to design as a dynamic creative process. Two key problems are identified, and on this background current computer methods intended for use in architectural sketch design are critically reviewed. As a result some guidelines are suggested for future research into computer- aided architectural problem solving. The purpose of the paper is twofold: (1) to encourage research that will take this field into a state of maturity and acceptance by practitioners, and (2) to provoke further debate on the question of how to do it.

summary Engineering involves both cognitive and calculational processes. It involves judgement as well as numeracy. Cognitive processes and judgement are better served by expert systems than other existing technologies. Expert systems are not designed to replace technologies currently used in engineering, rather they are and will continue to augment them. Clearly, better tools are needed and further education of engineers is needed. This conference aims to provide a forum for the presentation of developments and applications of expert systems in engineering, primarily in Australasia. The 20 papers accepted for presentation span the spectrum of engineering applications of expert systems from analysis and diagnosis, through simulation and modeling, learning, to design and synthesis
