title	Semantics and the Organisation of Knowledge in Design
source	Design Computing. 1986. vol. 1: pp. 68-89 : ill. includes bibliography
summary	The linguistic paradigm of design is considered. The idea of meta-languages is developed as a means of generating designs that are imbued with semantic content. The formulation of meta-languages therefore becomes a way of organizing knowledge about design. The usefulness of these ideas is demonstrated by means of programs developed in Prolog

title	Developments in Expert Systems for Design Synthesis
source	New York: 1986. pp. 193-203
summary	The applicability of expert systems to design synthesis is demonstrated. This is achieved by means of inference rules which can interpret design specifications in order to produce designs. This approach is applicable to certain classes of design problems which can be subdivided into independent subproblems. An expert system which contains knowledge about conflict resolution applicable to the more general class of design problem is demonstrated

title	CAAD in the Architectural Education of the Fachhochschulen in the Federal Republic of Germany
doi	https://doi.org/10.52842/conf.ecaade.1989.x.w7a
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 4.3.1
summary	For over 10 years the author has been a teacher in the field of "computer application in architecture" at the Fachhochschule. Since 1985 he regularly has been taking part in the conferences of A.I.I.D.A. (Arbeitskreis INFORMATIK IN DER ARCHlTEKTENAUSBILDUNG). All the faculties of architecture at the Fachhochschulen (about 10) can send their representatives of CAAD to the conferences. A.I.I.D.A. has been having 2 conferences a year since 1985. At the last conference in Wiesbaden a paper with statements of A.I.I.D.A. for the further education in CAAD was finished. The author presents and explains this paper. On the other hand he shows the actual education program of CAAD of his faculty. The education in CAAD started in 1972 with basic information without practical elements. Now the practical work with the workstation is talking most of the time . The computer application is available for subjects like Building Economics, Building and Structure Design and others. With his assistant the author developed programs of the field of Building Economics. In 1986 he started introduce CAD with AutoCAD in the education program. Now also other colleagues start to integrate CAAD into their subjects.

title	Alternative Models of Architectural Practice: The Impact of Computers -- 1990 and 2000
doi	https://doi.org/10.52842/conf.acadia.1986.007
source	ACADIA Workshop ‘86 Proceedings - Houston (Texas - USA) 24-26 October 1986, pp. 7-27
summary	Though many architectural firms have only recently begun to use computers, and most firms still do not use computers for design, it is likely that by the turn of the century computers will have transformed architectural practice. First this paper assesses the likelihood of change by examining the potential use of computers in architectural practice, summarizing technology forecasts for computer hardware, software, and standards. -However, because there is an opportunity, architectural firms will not necessarily computerize. Next is a brief review of impediments to change and the process of organizational adaptation of new technology. Finally, the paper concludes with a number of forecasts in architectural practice in 1990 and 2000. A variety of professional practice options are defined, with the suggestion that there will be increasing experimentation and diversity within the profession. Finally, the implications of these changes are explored for architectural education.

title	A Format for a Graphical Communications Protocol
source	IEEE Computer Graphics and Applications vol. 6.no. 3 (March, 1986): pp. 52-62
summary	This article describes the requirements for a graphical format on which a graphical on-line communications protocol can be based. It is argued that on-line graphical communications is similar to graphical session capture, and thus the author proposes an interactive graphical communications format using the GKSM session metafile. The discussion includes items that complement the GKSM metafile such as a format for on-line interactive exchange. One key application area of such a format is multimedia on-line conferencing. Therefore, a conferencing software architecture for processing the proposed format is presented. This format specification is made available to those planning multimedia conferencing systems

title	Three-dimensional Input and Visualization
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 68-84
summary	The aim of this chapter is to investigate techniques by which man-computer interaction could be improved, specifically in the context of architectural applications of CAD. In this application the object being designed is often an assembly of defined components. Even if the building is not actually fabricated from such components, it is usually conceptualized in these terms. In a conventional graphics- based CAD system these components are usually represented by graphical icons which are displayed on the graphics screen and arranged by the user. The system described here consists of three- dimensional modelling elements which the user physically assembles to form his design. Unlike conventional architectural models which are static (i.e. cannot be changed by the users) and passive (i.e. cannot be read by a CAD system), this model is both 'user generated' and 'machine readable'. The user can create, edit and view the model by simple, natural modelling activities and without the need to learn complex operating commands often associated with CAD systems. In particular, the user can view the model, altering his viewpoint and focus of attention in a completely natural way. Conventional computer graphics within an associated CAD system are used to represent the detailed geometry which the different three-dimensional icons may represent. In addition, computer graphics are also used to present the output of the performance attributes of the objects being modelled. In the architectural application described in this chapter an energy- balance evaluation is displayed for a building designed using the modelling device. While this system is not intended to offer a completely free-form input facility it can be considered to be a specialist man-machine interface of particular relevance to architects or engineers.

title	From 2D Base Map To 3D City Model
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary	Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title	CAD and Management of Construction Projects
source	Journal of Construction Engineering and Management, Vol. 112, December, pp. 557-565
summary	The increasing interest in computer-aided design (CAD) has prompted research that is aimed at identifying the opportunities for construction managers and building contractors. It has been found that the use of CAD systems in the U.K. is mainly confined to the production of detailed drawings. Indeed, most of the systems used are 2-D drafting tools and incapable of supporting the integration of even modest amounts of nongraphical (construction) data. On the other hand, many 3-D modeling systems have the potential to integrate construction data, although they appear to be almostignored. The use of 3-D modeling systems is considered to be the most suitable vehicle for successfully integrating these data. However, this is likely to necessitate the introduction of separate databases, preferably of the relational type. The use of 3-D modeling systems in assessing the construction implications of outline designs also presents interesting possibilities and is discussed.

title	Knowledge-based Design Optimization
source	IAAI'86 Conference. 1986. pp. i:4:1-14
summary	CADLINE has abstract only. Optimization is a well understood process in design domains. A designer formulates the design problem as a single criterion or multicriteria optimization problem and then selects an appropriate optimization algorithm to search for the optimal values for the design variables. The formulation and algorithm selection procedures have been considered to be activities which relied on substantive human knowledge. This paper describes a computer system, OPTIMA, which formulates design optimization problems from a pseudo-English description into canonical algebraic expressions. It then recognizes the formulation and selects appropriate algorithm(s) for their solutions. Finally, it runs the selected algorithm(s) and sends the results to the original descriptions. Areas of expert knowledge involved in carrying out the above tasks are identified. Such knowledge is explicitly encoded in the systems. The basic philosophy and key features of the system are described and are illustrated by examples

title	Formulating and Recognizing Engineering Optimization Problems
source	Aus. Conf Mechs. Struct. and Mats (10th : 1986 : Adelaide) edited by G. Sved. pp. 223-228. CADLINE has abstract only.
summary	In applying optimization methodology to engineering design, a considerable amount of knowledge is utilized to construct and solve mathematical design models. However, computer based systems to assist this process have concentrated mainly on the numeric computational aspects of the process. This paper outlines a computer system which uses a knowledge-based systems approach to formulate and recognize design optimization problems. Areas of expert knowledge involved in mathematical design modeling and optimization are identified. Such knowledge is encoded explicitly in the system. An example is presented

source	Teaching and Research Experience with CAAD [4th eCAADe Conference Proceedings] Rome (Italy) 11-13 September 1986, pp. 157-166
summary	This study has been carried out during the Course of Ergotecnica Edile hold at the Instituto Dipartimentale di Architettura e Urbanistica of Catania University, and it has been addressed to the students of the Faculty of Civil Engineering (manufacturing and direction of civil works). The present study aims at instructing the students as refers to planning, through computers, erecting yards. Work-planning is specifically important with reference both to the starting program and to the carrying on of the work. Within this context, workplanning is useful as regard the control and contingent correction of the work. In the latter case, divergencies between work-evolution and forecast are of primary value.

title	CAD System (Computer Aided Design) for the Planning of the Territory, with Reference to the Automatical Estimate of Works of Urbanization
doi	https://doi.org/10.52842/conf.ecaade.1986.167
source	Teaching and Research Experience with CAAD [4th eCAADe Conference Proceedings] Rome (Italy) 11-13 September 1986, pp. 167-179
summary	Any applied research, no matter what discipline is concerned, needs affined and suitable tools; as regards the studies in the field of architecture and planning, the use of automatic systems of analysis, data ordering and comparison is of particular interest. The quickness of operations by means of computers and the corresponding graphical representation gives new possibilities for scientific work, once impossible, not certainly because of conceptual limits, but practically, for the limits of available tools. It is the wideness of applications of computers to be pointed out, for although studied for scientific reasons, their practical usefulness is often enormous. This has been generally verified. It guilts in particular for the CAD System, proposed and explained in this paper. The practical utility this and other systems from the same field have for the public administration, contractors and consultants is well known and therefore not necessary to be described further. The use of such systems is particularly convenient in those sectors where the graphical representation is the basic part of the production process.

title	A General Version of Crow's Shadow Volumes
source	IEEE Computer Graphics and Applications September, 1986. vol. 6: pp. 17-28 : col. ill. includes bibliography.
summary	In 1977 Frank Crow introduced a new class of algorithms for the generation of shadows. His technique, based on the concept of shadow volumes, assumes a polygonal database and a constrained environment. For example, polyhedrons must be closed, and polygons must be planar. This article presents a new version of Crow's algorithm, developed at the Universite de Montreal, which attempts a less constrained environment. The method has allowed the handling of both open and closed models and nonplanar polygons with the viewpoint anywhere, including any shadow volume. It does not, however, sacrifice the essential features of Crow's original version: penetration between polygons is allowed, and any number of light sources can be defined anywhere in 3D space, including the view volume and any shadow volume. The method has been used successfully in the film Tony de Peltrie and is easily incorporated into an existing scan-line, hidden-surface algorithm

title	ADAM - Architectural Design Applications Model
doi	https://doi.org/10.52842/conf.acadia.1986.037
source	ACADIA Workshop ‘86 Proceedings - Houston (Texas - USA) 24-26 October 1986, pp. 37-54
summary	This paper will describe ADAM, a project to explore the potential for interfacing independent graphics software for the purpose of developing a microcomputer based design system. This system will be implemented in three undergraduate design studios at the University of Illinois (Urbana-Champaign) School of Architecture. The three design studios are part of an experimental project to determine the usefulness of computers in the architectural design curriculum. The concept used throughout the design of this system is: "make use of what already exists, but use it smoothly together in such a way that the management system is totally invisible to the user." Many low- end quality graphics software packages are commercially available. Each has the capacity to address some aspect of the architectural design process, none will do it all . The problem is a lack of compatibility between software. ADAM is a management system designed to invisibly control and interface the use of an assembly of graphics programs and data base management systems to achieve compatibility. Because of these compatible interfaces, new and varied design tools can be created from existing software..
