If can establish an information library of these parts based on CAD, the efficiency and quality of design will be effectively improved. While the parts library based on digital 3D model is a good kind of resolvent, so it is very significant to research method and technique based on 3D CAD system. Because of abroad using of UG at present, his paper explores 3D parts library CAD technology based on UG platform which aims at standard and series part design of general mechanical product. In this article, the main idea of parameterized technical theory was illuminated, the expression methods of geometrical constraint and the 3D parameterized model were introduced in detail, the speed of the UG software modeling was improved. Through the establishment of UG parts library, so as to shorten the product development cycle of the whole, and parts are called directly, realize resource integration.
