Interoperability between Cooperative Design Modeller and a CAD System: Software Integration versus Data Exchange

International audienceThe data exchange between Computer-Aided Design (CAD) systems is a crucial issue in concurrent engineering and collaborative design. The paper presents research works and techniques dealing with the interoperability of a Cooperative Design Modeller (CoDeMo), aiming at the integration of product lifecycle knowledge, and a commercial CAD system (CATIA V5). Two kinds of approaches are implemented in the considered case of CAD interoperability for exchanging geometric data, respectively: one is based on a traditional static interface, in which STEP AP203 standard is used; the other is based on a dynamic interface, in which Application Programming Interfaces (API) of the targeted CAD system is adopted. Both approaches should enhance the communication, exchange and sharing of product data between CAD systems for improving concurrent engineering. A comparison between these two approaches is made to show their particular advantages and disadvantages. The development of a translator between the both CAD systems based on each approach has been carried out and evaluated on an assembly case

FEATURE MODELLING

U radu su predstavljeni osnovni načini razvoja modela značajke proizvoda. Istraživanja i unapređenja modeliranja pomoću značajke, kao modeliranja proizvoda koji omogućava pohranu geometrijskih i funkcijskih informacija u jednom modelu, nisu u potpunosti ostvarena. Uz pregled većih nedostataka koji prate sadašnje sustave za modeliranje pomoću značajke, a to su održanje značenja značajke, postojanje samo jednog modela proizvoda, ograničene mogućnosti kolaborativnog modeliranja i ograničena domena oblika, prikazana su i istraživanja usmjerena rješavanju tih nedostataka.The paper presents basic ways for the development of product feature model. The investigation and improvement of feature modelling, as product modelling that enables geometrical and functional information to be stored in a single model, has not been accomplished completely. Along with survey of major shortcomings that accompany current feature modelling systems, consisting of maintenance of feature semantics, the existence of only one product feature model, the limited facilities of collaborative modelling, and the limited shape domain the investigations aimed at solving these shortcomings are also presented

Literature review

There are many studies that reveal the nature of design thinking and the nature of conceptual design as distinct from detailed or embodiment design. The results can assist in our understanding of how the process of design can be supported and how new technologies can be introduced into the workplace. Existing studies provide limited information about the nature of collaborative design as it takes place on the ground and in the actual working context. How to provide appropriate and effective of support for collaborative design information sharing across companies, countries and heterogeneous computer systems is a key issue. As data are passed between designers and the computer systems they employ, many exchanges are made. These exchanges may be used to establish measures of the benefits that new support systems can bring. Collaboration support tools represent a fast growing section of the commercial software market place and a reasonable range of products are available. Many of them offer significant application to design for the support of distributed meetings by the provision of video and audio communications and the sharing of information, including collaborative sketching. The tools that specifically support 3D models and other very design specific features are less common and many of those are in prototype stages of development. A key question is to find viable ways of combining design information visualisation support with the collaboration support technologies that can be seen today. When collaborating, different views will need to be accessible at different times to all the collaborators. The architects may want to explain some ideas on their model, the structural engineers on their model and so on. However, there are issues of ownership when the structural engineer wants to manipulate the architect’s model and vice versa. The modes of working, synchronous or asynchronous may have a bearing as in a synchronous session there is control of what is happening
