Abstract
A recognition process of the features in a part model uses the knowledge of an application engineer. The knowledge is encoded as rules of the recognition procedure that are applied to the part model during the recognition process. Such a human interaction is difficult to control in extracting the moulding features because the features moulding of the application engineer may change from one engineer to the other and external conditions may change. Instead, we treat the result of the recognition process as a first approximation of the user's intention and let the user interactively modify the result. In this paper, we present a feature recognition system where the user can inspect the result of the recognition and delete the recognised features interactively.
