To shorter product development time, this paper proposed an approach to developing feature based parametric product modeling systems which are suitable for integrated engineering design in CIMS environment. The architecture of ZD-MCADII and the characteristics of its each module are introduced in detail. ZD-MCADII's product data is managed by an object-oriented database management system OSCAR, and the product model is built according to the standard STEP. For the product design is established on a unified product model, all product data are globally associated in ZD-MCADII. ZD-MCADII provides various design features to facilitate the product design, and supports the integrity of CAD, CAPP and CAM.
