【Abstract】 ARX is a new kind of object-oriented developing environment in AutoCAD system. On the base of the detailed introduction of the features and functions of ARX, some key technical problems in developing CAD system of wind-tunnel balance are discussed, such as general structure of system, database building, mathematics model of resistance optional design, and using MFC to make graphical user interface (GUI). The feature of ARX, supporting object-oriented technique, changed traditional modes of developing CAD software, and presented a broad application in the future.更多还原
