In this ESPRIT research report of a group of engineers in the CAD*I project the possibility of using a database management system (DBMS) for computer aided design (CAD) purposes is analyzed and conditions are derived that enable CAD systems to manage CAD models containing increasing amounts of data and more and more intelligent relations. Today CAD models constitute isolated islands of data stored in independent files, and to create and maintain relations between pieces of information stored in several models (files) in a multi-user environment is a complex task. At a conceptual level, a relational DBMS associated with the language SQL (ISO standard) is the ideal tool to create and maintain such relations. At the implementation level, it is of the highest importance to define the optimum granularity of information to be stored in the database in order to get a good response time from such a system.

Principal authors: U. Kroszynski, B. Palstr9Sm 1.1 The evolution of concepts and specifications for CAD data exchange The CAD/CAM community has witnessed, during the last decade, the appearance of several specifications as well as proposals for standards which either attempt to cover wider areas or to be more reliable and stable than the others. With the rapid evolution of both hardware and software, the capabilities offered by CAD systems and CAD based application systems are far more advanced than they were only ten years ago, even when they are now based on micro-computers or personal comput ers. The situation with standards, however, is not and cannot be so. In order to be reliable and accepted by a wide community of both vendors and users, a standard has to be sta ble. This implies a life span of at least a decade. This also implies that the standard has to be general and flexible enough to accommodate present as well as expected future developments. 1.1.1 IGES The initial development of concepts for CAD data exchange is strongly influenced by the US Integrated Computer Aided Manufacturing (ICAM) programme, that dealt with the development of methods for data exchange. In September 1979, a subgroup was estab lished with participation of the National Bureau of Standards, the General Electric Com pany, and the Boeing Company. The result of this effort was the Initial Graphics Exchange Specification (IGES) that was published as a NBS report [61] in 1980.

The Product Data Technology Advisory Group, short PDTAG, was established on 30 September 1992 under the auspices of the ESPRIT CIME Division of the Directorate General XIII of the European Commission. Its goals include promoting European cooperation and improving the European infrastructure in Product Data Technology, particularly in connection with the new standard STEP (ISO 10303). The dissemination of information on Product Data Technology and on European contributions to STEP is of crucial importance to this development. The current volume is the first title in a new PDTAG subseries to Springer Publishers' Research Reports ESPRIT. This new subseries intends to form a comprehensive repository of publications on Product Data Technology resulting from ESPRIT Projects and from European contributions to standardisation based on ISO/STEP. PDTAG welcomes the opportunity to make this information more accessible under the format of a coherent subseries within the established framework of Research Reports ESPRIT. Much valuable background on the new international PDT standard can thus be found in the same collection.

ESPRIT Project 322, "CAD Interfaces", has been established to define the most important interfaces in CAD/CAM systems for data exchange, data base, finite element analysis, experimental analysis, and advanced modeling. The definitions of these interfaces are being elaborated in harmony with international standardization efforts in this field. One principal goal of the project is to develop techniques for the exchange of CAD information between CAD systems, and from the CAD domain to CAA (Computer Aided Analysis) and CAM (Computer Aided Manufacturing). This volume presents a proposal for a neutral file format for CAD data: curves, surfaces, and solids. The specification is based on a reference schema for CAD data bases and is defined informally with respect to its semantics and formally with respect to its syntax. This volume is a revised edition of "Specification of a CAD*I Neutral File for Solids" Version 3.2. The revision reflects the enhancements which result from the implementation of communication processors in eight different CAD systems and from the practical exchange of solid models between these systems. Due to the close interaction between the CAD*I project and the coming-up international standard STEP this specification also serves as an introduction to the geometry model that will be included in the future international standard.

1.1 PURPOSE The purpose of this paper is to document the results of Working Group (wireframes), Working Group 2 (solids) ,and Working Group 3 (surfaces) of the ESPRIT project 322 CAD*I (CAD Interfaces). The goal of these working groups is: 1. Develop a neutral file format for transfer of CAD data (curves, surfaces, and solid models) between CAD systems, and from the CAD domain to CAA (computer aided analysis) and CAM (computer aided manufacturing). 2. Develop pre- and post-processors with a number of representative CAD systems for this neutral file format. 3. Develop representative test model files and perform cycle tests and inter-system tests for CAD model transfer. 4. Contribute to the standardization activities in the national standardi zation bodies and in ISO for the establishment of a neutral file format for CAD data. This paper corresponds to a development stage as it was reached on July 6, 1987.

'Object-oriented' has become one of the important buzzwords in computer science, but as yet there is no clear consensus on 'what' is object-oriented programming. This book addresses the concepts behind the buzzword, and has four goals. The first is to provide the reader with a perspective on concepts that have been in development in a diverse set of fields, including artificial intelligence, database theory, programming languages, and compiler theory which form the core of the object paradigm. Second, the text presents an overview of object-oriented databases, examples of their use, and a comparison of strengths and weaknesses. Third, real-world examples are shown to illustrate how they are mapped onto an object-oriented framework. Finally, the programming language C++ has been adopted by programmers of object-oriented databases, so there is an overview of its power and limitations, and two different approaches to making a database out of C++ are examined.

Designing and controlling complex shapes like porous volumes and rough surfaces is a challenge. Fractal geometry is an interesting approach which considerably simplify the problem. Even though underlying concepts reduce the set possible shapes, they generate a surprising variety of shapes. In this book we present a formalism to design such complex objects for geometric aided geometry design applications. The goal of this formalism is to provide to the end user the possibility to manipulate fractal objects as a standard euclidean object with standard tools of CAD system. This formalism encompass curves, surfaces, volumes, as well as NURBS and subdivision surfaces. All theoretical and practical aspects are developed, from the design up to 3D printing.
