Abstract	A rough set-based case retrieval method was presented in intelligent CAD system of the conceptual design. The case knowledge representation model of the conceptual design based on rough set was brought forward by analyzing features of CAD systems. An approach of reducing the feature attributes and calculating the feature attributes weighting was proposed based on rough set theory. The continuous feature attributes were discretized by using hybrid clustering method. Then the importance of the feature attributes were calculated first, and then the importance were normalized to weighting coefficients. It obtains the closest conceptual design case from the case database to take the design case as reference. The proposed method is also demonstrated by an application example.
