Aiming at the problem of low information integration between the current ERP information management system and CAD product design system,a product drawing management system oriented to the integration of ERP and CAD was designed and developed with hydraulic cylinder production as the background.The material information identification of CAD design drawings was extracted into the database of ERP system,and a special product BOM table style was automatically generated.The complete set of CAD design drawings of each product was bound to the order contract information,so that the production staff can search and browse the required drawings in real-time.Then according to the design parameters of the hydraulic cylinder,the drawings corresponding to the typical products were classified and standardized to form the enterprise basic product list and standard library,so that the designers can quickly complete the design of the new product accordingly.
