A process-oriented sheet metal unforming simulation system SW-BEX（stamping works-blank estimation xpert） with pre-process and post-process was developed, which was integrated into SolidWorks software and based on the inverse approach of FEM. The design process and development process of SW-BEX was introduced, and some key techniques of the system development were studied, such as meshing and constraint definition. By analyzing a typical sheet metal using SW-BEX, the easy operating, practicality of this system are demonstrated, and the simulation accuracy of this system was verified by comparing the simulation results with the experimental ones. SW-BEX is fully integrated into the SolidWorks platform, avoids the problem of accuracy loss caused by model data exchange between CAD platforms and traditional CAE software, and achieves the real CAD/CAE seamless integration. 
