The revolving speed is transmitted into the case by motor connected with flange and input axis, then lowered to the target rotating velocity through gear drive inside the case and exported by output axis. On both the top and the bottom of the case there are several screw holes for installation, through which the case is fixed by screws or bolts in operation. In order to facilitate the assembling and removing of shafts and gears, tank cover is required as well as an inspecting hole, which is convenient for operators to check whether the transmission is proceeding smoothly. In addition, there should be an oil gallery at the bottom of the case so as to facilitate the lubrication of transmission parts inside. There are more than 1 gear cases, wh ich involve several sets and more than 1 sizes in each set. Besides, the amount of dimensions in each case is extremely large as well. Obviously, owing to its arduous task, long-lasting developing period and low efficiency, its not wise to model them or modify their dimensions respectively. On the contrary, if we are capable to create one parametric odel for each set so as to generate products of all sizes, then the period of developing shall be reduced to great extent. The 3- modeling software Pro/Engineer has its own function of parametric design, which meets our demand completely. 2. Parametric design function of Pro/Engineer Parametric design (namely dimension-driven) is subject which has been put forward in the application of CAD technology. At present its also an important subject and to be further developed in CAD application field. On the basis of parametric designing method, the special products designing system is capable
