We have developed proven model using mesh automatic generation technique by similar sub-part search. The purpose of this development is to reduce interactive mesh improvement work time and to comply with the mesh specifications. We developed a series of techniques that include two major functions. First, sub-parts can be searched the CAD data of new design for similar sub-parts of the proven models. In this function, the similar sub-parts are retrieved from a CAD model described by boundary representation and made correspondence relation surface pairs of a retrieval model (proven model) and a target model (CAD of new design). A similarity score is based on the attributed graphs of a retrieval model and a target model. And, this score is calculated by a geometrical similarity and topological a similarity. Second, mesh can be generated automatically by arranging and merging the mesh of similar sub-parts. Experimental results show that this technique can efficiency achieve mesh generation without interactive mesh improvement operation.
