In future CAD systems the reuse of already existing design objects becomes a key functionality. Typically, in many design domains solutions for new problems are derived from successful cases. Thus, time consuming and expensive design development from scratch needs not to be done. The paper presents RODIN, a connectionist application supporting the reuse of manufacturing information for CAD objects. In RODIN two different problems in reusing of design objects are studied. At first, we present our work how to retrieve appropriate reference cases from a database. In the retrieval process multiple attributes are taken into account. Secondly, we show how information between structurally similar designs can be exchanged. The transformation step is performed by backprop nets. The work of the designer is supported by relieving him/her of routine matters. As a consequence both the time-to-market and the quality of the products are optimized. |
