【Abstract】 The modeling approach of part in parameterized CAD system based on optimized project design and implementation route were presented. The engineering constraint and optimized constraint computation were briefly stated. The application of optimized project design in parameterized CAD system was expatiated as well. It is concluded from engineering practice that the system can improve effectively the automaticity of die design.更多还原
