source Advancing Building Technology, CIB International Congress (10th : 1986 : Washington D. C.). 9 p. : ill. includes bibliography
summary It is now vital to aim at formulating computer system modules that possess a high ability to adapt their behavior to fundamental human values and a complex and unstandardized (not uniform) building process but at the same time put constraints on them so that we don't end up with a confusion of computerized routines hard to access, control and understand. In the paper formulations are made of basic artifact skeletons outgoing from the properties to give integrated CAD systems and to those rules by which the growth of the systems are governed. System learning domains including conceptual modelling tools are presented aiming at supporting professional skill, creativity and integration between process actors. The basis for system implementation is frames, descriptive language (PROLOG) and relational databases with regard taken to future possibilities to parallel processing

title A Conceptual Framework for Communication -Instruction in Architectural Design
source Pennsylvania State University
summary Existing design models, it is generally acknowledged, are inadequate to deal with the complexity of contemporary situations; and an assessment of self-conscious design manifests a slow development in the power and scope of conceptualizing. The quality of knowledge and conceptual tools available to the designer largely determine his ability to conceive and accomplish; conversely, the limitations of method are reflected in design solutions. Some emerging social problem-solving paradigms, which seek to construct a cognitive psychology of problem solving, have a direct relevance to architectural design. Notwithstanding the traditional criticism and scepticism, problem solving is predicated by task environment and problem space as these have a significant impact on design synthesis. Despite a rigorous search for theoretical perspectives and methods, the concern for the quality of the physical environment persists unabated. Historically, architecture has depended on other disciplines for its theoretical insight; but the application of borrowed theories without a viable framework for translation has often resulted in misinterpretation. Aggravating the problem is the art-science controversy which has consequences for architectural practice and education. What is required is a unified approach encompassing the scientific and artistic modes of inquiry. But a unified perspective, involving vast and disparate areas of human knowledge, demands a conceptual framework for integrative learning. The proposed model of this study provides such a framework and calls for a re-examination of the conventional boundaries of design disciplines. It advocates an interdisciplinary approach and recognizes the design process as inherently a learning process; this shifts the emphasis from product to process and allows students to plan and assess their own design/learning experience. While the study focuses on substantive issues, it identifies a strategy for integrative learning applicable within the existing context of design education. Despite its untested nature, the proposed model can become a vehicle for stimulating coordination of all facets of human knowledge and experience toward creative design synthesis. It inculcates a sense of critical assessment of generative ideas by presenting a conceptually clearer picture of the design process to elicit a response to and a better understanding of the task environment of architecture.

title Learning in the Domain of Decisions and Performances
source IAAI'86 Conference. 1986. pp. i:1:1-9. CADLINE has abstract only
summary Many domains present themselves as mappings between two classes of spaces: decision spaces and performance spaces. All design domains can be represented in this manner where the designer takes decisions which manifest themselves as performances in the designed artifact. Learning in these domains can take account of the structural characteristics of the spaces and of the mappings. This paper describes a system, PARE, which learns in the domain of decisions and performances by making use of the characteristics of a particular structuring concept known as 'Pareto optimality.' Much is known about the concept and its features which are used as hypotheses. If the hypotheses succeed then learning takes place by specializing the hypotheses' characteristics. Characterizations of Pareto optimality are described and the feature extraction process shown. The feature extraction process utilizes fuzzy pattern matching. An example of the system, written in ConSUN workstations, is presented from the domain of fenestration design

title The Computability of Architectural Knowledge

summary In an important contribution to the theoretical foundation of design computing, Mitchell noted "an increasingly urgent need to establish a demonstrably sound, comprehensive, rigorously formalized theoretical foundation upon which to base practical software development efforts" (Mitchell, 1986). In this paper we propose such a theoretical framework. A basic assumption of this work is that the advancement of design computing is dependent upon the emergence of a rigorous formulation of knowledge in design. We present a model of knowledge in architectural design which suggests a promising conceptual basis for dealing with knowledge in computer-aided design systems. We require models which can represent the formal knowledge and manipulative operations of the designer in all of their complexity-that is formal models rather than just geometric models. Shape Grammars (Stiny,1980) represent an example of such models, and constitute a relatively high level of design knowledge as compared to, for example, use of symmetry operations to generate simple formal configurations. Building upon an understanding of the classes of design knowledge as the conceptual basis for formal modeling systems may contribute a new realization of the potential of the medium for design. This will require a comprehensive approach to the definition of architectural and design knowledge. We consider here the implications of a well-defined body of architectural and design knowledge for design education and the potential mutual interaction-in a knowledge-rich environment-of design learning and CAAD learning. The computational factors connected with the representation of design knowledge and its integration in design systems are among the key problems of CAAD. Mitchell's model of knowledge in design incorporates formal knowledge in a comprehensive, multi-level, hierarchical structure in which types of knowledge are correlated with computational concepts. In the main focus of this paper we present a structured, multi-level model of design knowledge which we discuss with respect to current architectural theoretical considerations. Finally, we analyze the computational and educational relevance of such models.

summary Stages in the formation of concepts necessary for mastery can be observed in cognitive development in many different areas of study. These stages seem to follow a particular hierarchy common to most learners. Distinct levels can be recognized by patterns of procedural errors. The remediation of errors can then take the form of building a conceptual framework rather than training in procedural patterns. This has been found to be highly efficient for learners at all stages since it can be aimed at the underlying problem area and not at isolated errors which may change frequently. It was felt, that concept development of architects learning to use computer-aided drawing programs would show such levels. Preliminary studies made at the U.S. Army Construction Engineering Research Laboratory upon selected subjects using computer-aided lessons in AutoCAD as a basis for observations reveal several categories of errors in using computer-aided design. These case studies show that the design process can be enhanced by automated drawing and design tools if the conceptual relationships are established as a part of the learning environment. Even more important, the observations show that architects have particular characteristics which differ from engineers and other CAD users. These differences require that education and software be tailored to their needs.

summary After an introduction describing the present situation on computer- programs used in learning environments, some remarks are made on what future programs should look like. Although the design and the building process are both extremely complex, a proposal is made to carry out a project in a joint effort among ECAADE members to achieve a new generation of learning tools. These tools should also be of good service in a consulting environment.

title Visual-Physical Grammars
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

title ADI : An Adaptive Database Interface for Dynamic Databases
source ASME Symposium Proceedings on Knowledge based Expert Systems for Manufacturing. Anaheim, CA: American Society of Mechanical Engineers, Production Engineering Division, December, 1986. pp. 119-130. CADLINE has abstract only
summary The operation of a manufacturing organization often depends on its underlying design and manufacturing databases. In a manufacturing environment, many users, both individuals and application programs, must have access to one or more of the organization's databases to provide, use, or modify data, to control information flow, and to facilitate information management. Such databases routinely undergo dynamic changes in both their content and their structure. These changes commonly result from the design of new products, the introduction of new materials, and the introduction of new machines and processes on the shop floor. Such continuing changes must be reflected in the database schemas and subsequently require that application programs be updated and that online users be educated on a continuous basis. The problem addressed in this paper is that it is difficult for users and application programs to get the information that they need, when they need it, from the multiple heterogeneous database management system (DBMS) environments that have evolved in design and manufacturing organizations. The solution proposed here is to build a general, extendable interface between database users and the many sources of data available to them. This in itself is not a new suggestion; a number of researchers have addressed portions of this problem. In general, the interfaces that they have developed to date are best suited to environments where the structure of the database is static and does not change over time. One of the things that this paper proposes that is different from existing work is an interface which handles the dynamic restructuring nature of manufacturing databases, enabling a user to obtain the most accurate and up to date information as the structure and content of the underlying databases change. Another unique aspect of the DBMS interface proposed herein is that the interface attempts to capture the knowledge that an experienced human user incorporates in his search for data in a database, i.e., it seeks to identify and use the generic knowledge needed to operate a DBMS. This knowledge is used by the interface to enable both the online users and the application programs to request data without knowing the data's location or precisely how to ask for it. Further, the interface makes use of mechanisms that allow the user to request data without knowing the exact identity of the required entities that are stored in the database

title A Manufacturing Hand
source pp. 13- 23 : ill Pittsburgh, PA: Engineering Design Research Center, CMU, September, 1986. includes bibliography.
summary In unmanned Flexible Manufacturing Cells, robots can be used for loading machines, inspection activities, and assembly operations. What kind of robotic end-effector should be built for such tasks? The human hand has evolved to be a general purpose manipulator that adapts to the richness of our daily lives but, in doing so, it is not particularly suited to manufacturing operations. Here, special tools, fixtures, and protective layers are heavily relied on. This paper describes the initial development of a hand specifically for manufacturing work. This has involved the manufacture of an instrumented wrist with an adjustable remote center of compliance, and the design of fingers for gripping. Object shapes have also been analyzed in order to provide for a stable static grip. Importantly, these studies of the physical aspects of prehension have been matched to tasks. The research has considered a range of industrial operations and specified the level of end-effector control needed. This work is leading to some design guides for robotic end-effectors which, it is hoped, will be of use to industrial designers

summary The theme of this Acadia Conference was to a large extent addressed by Mitchell in his article "'What was Computer-aided design?"', published about two years ago. While one has to agree with most of his points, I find his predictions gloomy enough to wish I could disagree. Luckily, Mitchell has chosen to address what the majority of the profession (and many architectural schools) currently consider to be CAD. It turns out that this CAD is not what CAD is supposed to be. I have, therefore, purposely chosen a title which appears to echo an opposite view. My intention is not to express disagreement but rather to project the other face of CAD, in my own mind, the only CAD which deserves the name. Whether the current CAD should or will be called CAD in the future is of non-essential significance. As teachers of architectural design we need to be concerned that architectural CAD remains, to date, a very immature field. It is CAD only by name, since a true CAD system has yet to be 'discovered". This presentation consists of three major sections. The first reviews why the currently available CAD systems do not have the ingredients which may justify them as design oriented machines. This discussion leads to the identification of architectural modeling and knowledge systems as the two main areas which need to be researched so that they may offer the basis for the development of truly design oriented machines. Each is discussed under a separate section, but the point is also made that the two should work hand-in-hand and should be integrated into a completely unified system.

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

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.
