Computer Graphics Job Correcting Software, A Number Of Key Technology Research

Several important technologies for the software aimed to correcting machine parts drawing were discussed in detail and the solutions were provided also. All drawing errors have been divided into two sets which were absolute errors sets and comparative errors sets according to the property of the error. Absolute errors processing include four modules which were Line-Weight Checking module, Hatch Checking module, Dimension Checking module and Redundant-Line Checking module. Comparative errors processing include three modules which were Drawing Compartmentalization module, View Recognizing module and View Matching &Checking module. The application of all solutions and algorithms were illustrated with a typical shaft-like parts drawing. The instances of the application were presented and the conclusions were also made.
