In reverse engineering it is necessary to reconstruct a surface that can be trimmed with other surfaces. The cloud points should be partitioned into appropriate feature regions so that each of them can be fitted into a surface. We proposed a data segmentation algorithm for the partition of the triangular meshes. It was composed of the following four steps: computing characteristic values, feature regions classification, merging unnecessary regions and partitioning meshes. An integrated procedure incorporating the above steps and appropriate user interface was proposed for realistic implementation. Successful examples were provided also to demonstrate the feasibility of the proposed method.
