In traditional reverse engineering, the reconstructed B-rep model is difficult to show design intents, because it can only represent the low layer geometric information of part. In order to avoid the shortcoming of B-rep, a new strategy of feature model reconstruction based on point cloud is presented in this paper. Estimation of normal vector and curvature is a basic and pivotal process in this strategy. The accuracy of traditional coordinate transformation method is to low, so a new method is proposed.
