【Abstract】 Taking a typical machine product for example, the methods of characteristic parameter modling and product assembling design were introduced. Its dynamic demo function was implemented. Computer aided design method of 3D solid model to generate parts automatically was described. The digital models of all parts are able to be directly exchanged into DXF format file for NC machining. All parts are assembled dynamically to generate product assembling model, which can be checked up for assemble interference. Computer aided design process for dynamic demo to create a product exploding view is implemented. The product assembling, disassembling and cutting-open models can be used for propagandizing product performance. The digital model can realize information share and integration management from modeling design, finite-element analysis, machine simulation, dynamic interference check-up to product manufacture, assembling, and propagandizing for sale.更多还原
