Plate Covered Parts Diagram Operations Automatically Correcting Software Technology

The plate is one of the most familiar parts in engineering, with a feature of a revolving body. According to this and with the help of development tool Object ARX for AutoCAD, the paper discuss some important technologies for computer to correct the plate works generated by AutoCAD and put forward some key algorithm for implementing under the development environment VC++6.0.The paper present a delicate Block Division Algorithm for AutoCAD drawings ,uponed which both direct graphics element compare and character compare are introduced to solve problem between the drawings with the different expression .Beside this ,the paper also give a description of Preprocessing module, Block Division module, Identifying module, Drawing Uniform module, Graphics Comparing module and Displaying module. In the final, an instances of random correcting result of a plate justify the correctness rationality of the technique.
