The research on 2D graph parametrizing technique is carried out in accordance with the problems of the CAD developing technology used for mechanical products.The parametrizing design of assembly drawing based on graph unit techniqae is put forward and an organic whole of structure design and parametrizing design using ActiveX Automafion technique is implemented.On this basis,Combining with the professional knowledge for mechanical design is developed the CAD soft ware package for the “CAD of the expansion joint and parametrizing plotting system”. Through designing the inferface,establishting the date bank,compiling the algorithm etc,this paper implements the stracfure design and oprimum design of the expansion joint and realizes the expansion joint's CAD and the graph parametrizing design of the paths and assembly drawing,therefore the expansion joint's and plotting efficiency can be increased greatly.
