This paper describes a preliminary report on a project to develop the core of a computer-aided concurrent engineering system, called PRODES. First an overview is given on the different approaches to feature-based design, which has been further developed to result in the shape design and modelling methodology of the PRODES system. This methodology, detailed in the second part, is based on the abstract object concept. Abstract objects have varying structural topology and shape geometry. They can be qualitatively characterised by and selected based on their functions. In the third part of the paper, the architecture and the different operating states of the PRODES system are described. Finally, the semi-generative methodology of manufacturing process planning with the PRODES system is described.
