Abstract:STEP is an international standard for the computer-interpretable representation and exchange of product data. In this paper, the basic idea of data exchange through STEP neutral file among different systems is illustrated. According to this mechanism, a data exchange interface, which is based on STEP neutral file between system of CAD and system of visualization in scientific computing is designed and implemented. To test the interface, a complex modeling data of geometrical body is read into the system of visualization in scientific computing through it. The result data of transferred geometrical body is successfully used in anal- yzing and showing complicated data field.
Keywords:computer aided-design  STEP  data exchange  tetrahedral mesh
