Abstract Feature-based translation of computer-aided design (CAD) models allows designers to preserve the modeling history as a series of modeling operations. Modeling operations or features contain information that is required to modify CAD models to create different variants. Conventional formats, including the standard for the exchange of product model data or the initial graphics exchange specification, cannot preserve design intent and only geometric models can be exchanged. As a result, it is not possible to modify these models after their exchange. Macro-parametric approach (MPA) is a method for exchanging feature-based CAD models among heterogeneous CAD systems. TransCAD, a CAD system for inter-CAD translation, is based on this approach. Translators based on MPA were implemented and tested for exchange between two commercial CAD systems. The issues found during the test rallies are reported and analyzed in this work. MPA can be further extended to remaining features and constraints for exchange between commercial CAD systems.

The purpose of this paper is to develop a practical method which integrate the mighty function of GIS with KBS (Knowledge Based System) .It emphatically bring forward a prototype of KBGIS. The research is an example of GIS-KBS integration in which the elements of KBS techniques are actually integrated with GIS. The idea of the prototype KBGIS system design was to put the model, data, domain knowledge, and the system's knowledge acquisition and reasoning mechanism and GIS together into a same environment.

The Design System mfk will support the designer by an object-orientated synthesis of parts and an integrated knowledge-based analysis. An own-product model which is completely independent from the data structure of the used computer aided design (CAD) system contains all necessary information on geometry, technology, function and organization. It allows different types of analysis: design for production, tolerance analysis, cost and stress calculation, repeated component search, etc. Usable for products of higher complexity the Design System can be seen as an approach to an engineering workbench.

A Company

This article highlights that by using a standard that enables complete product model data to be transmitted digitally, a company can build open systems to make information available on many platforms throughout its operations. The world of CAD/CAM has viewed the International Graphics Exchange Standard (IGES) as its translation standard for years, using the system to move two-dimensional models from one program to another. While IGES does, in fact, do a good job of transmitting basic geometry, another translator—the Standard for the Exchange of Product Data (STEP) —has been gaining on IGES in popularity. STEP goes considerably further than just transmitting geometry; it provides users with the ability to express and exchange digitally useful product information throughout a product's life cycle, including design, analysis, manufacturing, and support. In short, IGES transmits two-dimensional drawings, while STEP transmits complete product models. The updated schema, consisting of an ASCII file written in EXPRESS, is simply run through a utility that merges the extensions that have been added by Unigraphics with the standard ST-Developer libraries. Updating the translator to incorporate an upgraded version of the libraries is just as easy.

The development of control software for mechatronic systems requires data and information from all design domains in order to create the required integrated functionality. This paper proposes a method that combines function modeling and multi-domain modeling primitives to generate control software. Provided a function model based on the Function-Behavior-State modeling paradigm and performance requirements, a knowledge-based engineering application instantiates a virtual product model and control software for a target platform. Object-oriented modeling techniques provide for the development of primitive libraries, which represent both hardware and software components, while integrated design rules ensure that components are correctly placed and connected. Requirements are translated to software specific parameters. A case study of a mobile robot shows that for specific applications both target and simulation control software code can be generated from the same input, and a generated virtual product model can serve as a simulation model in order to validate functionality.

Abstract In this work the problem of designing a CAD-system independent product model data base, to be used in computer aided elastomeric seal design, is treated. It is shown how a general purpose turn-key CAD-system can be used together with an external product model data base and external calculation programs. The importance of storing product information in a CAD-system independent data base instead of on drawings in one particular CAD-system is pointed out. This is of special interest from long time storage point of view, as product related information is expected to live longer in a manufacturing company than one particular CAD-system. In order to be able to transmit data between the CAD-system and the external product model data base, and between the data base and the external calculation programs, special interfaces must be designed. Here it is demonstrated how such interface programs can be designed using FORTRAN 77 and a particular graphic application program language available in the CAD-system CDM 300. For the creation of the data base and for the data storage and data retrieval, the data base management system TORNADO is used. Finally the simultaneous use of the CAD-system, the external data base and the calculation program, when designing an elastomeric seal cross section, is demonstrated with a test example.
