Abstract: Aiming at the problems of cumbersome process and so many parameters in modeling the boom of hydraulic excavator's working device，parametric design of the boom was realized by the database technology and the secondary development of UG software to enhance design efficiency．Firstly，the CAD model of a certain type of excavator's boom was built by UG software，the control program and user interface dialog were developed by the secondary development tools of UG and C++ language．Secondly，the database of model was established with the database technology，the database of model’s geometric parameters were founded by Access and the source of datas was registed，the dialogue frame of CDataChoice and CInsertDialog was  created to access the database and call the geometric parameters of model，or edit and modify the parameters of database．Finally，the environment variable of system was changed，the model was obtained by inputing or calling relevant parameters．The research results indicate that, this parameteric design method can greatly simplify the  process of design, and it can increase the efficiency．
