【Abstract】 A modeling method of history-based user-defined feature is proposed and implemented in a3d parametric system named Intesolid,a self-developed CAD system copyrighted by CAD Center of Huazhong university of science and technology.It realized the reconstruction of user-defined feature with assurance of the design intention.Moreover,it makes the design process more efficient and enables the reusing of designed part,as well as simplifies the maintenance of feature database.更多还原
