As a method to input 3-dimensional configuration for the finite element analysis we are required to create a set of triangles as to cover whole surface of the shape using point clouds on the surface. For smooth surface the neighbors for each point are sufficient to create triangles necessary to surround the point, but difficulty appears to generate triangles close to feature lines appearing on the surface. Present paper explains two different methods to extract features from point clouds which are prepared by the users.
