The Research And Realization Of 3-D Standard Parts Library System Based On UG

CAD (Computer Aided Design) technology is an important field of the current application of computer. With the development of CAD and network database technology, the research of standard parts library (SPL) based on web is becoming more and more important and more research is done on it. The development of Client/Server (C/S) mode network SPL based on UG is studied in this paper.Firstly, this paper illuminates the background and significance of the research, and summarizes the correlative articles and the existing research on standard parts library. This paper also introduces the software UG and customized development methods of it.Secondly, the framework of 3-dimension parametric standard library is brought forward by using the structure of C/S. Using the design method of relational database, we construct the conceptual design, logic design and physical design of the database of this system.Then, we make in-depth research on the key technology of SPL system. We present a method for calling MFC in UG, which solves the interface problem among UG, MFC and database. We present a method for driving three-dimensional model of standard parts based on parameterization.In the end, this paper summarizes the whole paper, illuminates the achievement of the paper, and points out some questions to be further gone into.The SPL system which is based on UG NX 4.0 and is developed with VC++ 6.0 and SQL server 2000 makes use of UG/Open API technology and ADO database interface technology. We finally finish the development of C/S mode network SPL based on UG and attain the prospective purpose.
