The extraction of drilling and riveting point’s process information is the basic of off-line programming system. On the CATIA/CAA platform, the MBD digital model’s coordinates, vector, symbol, mark were extracted. For the purpose of the correction of vector’s direction, vector calibration and correction module was developed, by creating a reference line. In the end, an example of aircraft panel part was given to demonstrate the feasibility of this system. The results indicate that it can effectively extract corresponding process information from MBD model and distinguish abnormal vector and correct it.
