Abstract:For the problem of recognition unsatisfactory of intersected features, the member value of extended attributed adjacency matrix was indexed and changed, the features with common surface were merged, and the features with no common surface were recognized by calculating whether their outlines had adjacent. For the order of removing small features, the depending features were first removed and then the depended features by building relationship between intersected features. The machining allowances on surfaces with higher requirements was added, and the split face was automatically selected or selected by users, thus the draft?angle was generated directly. The examples were demonstrated to verify the validity of the proposed method. © 2018, Editorial Department of CIMS. All right reserved.
