In order to improve general aviation aircraft product for processing quality, digital definition model and optical measurement positioning technology is gradually applied to the navigation product in the quality inspection system. A laser tracker measurement software and supporting Polyworks navigable surface measurement process product were used for process planning and the measurement path visualization process simulation to provide theoretical and process guidance for field measurements navigable surface product onsite. In order to raise the proposed measure fitting accuracy freedom positioning reference point coordinates snap to the nearest point iteration algorithm point data alignment method of combining surface product measuring coordinates could be mapped to the designed set coordinates to complete unified digital measurement coordinate system, and examples verification. The CATIA development interface was used with CAA C ++ technology as a second development means complete access to information, and three-dimensional (3D) computer software and laser tracker measurement software Polyworks completed measuring point communication. The macro scripting language (MSCL) editing program is used to coordinate after conversion measuring point path simulation to generate a visual digital measurement process.
