Abstract: Main user function and its engineering applications of graphics kernel supportingsoftware-CGI on IBM computer in aeronautical field are summarized in this paper. CADsystems developed by usage of CGI have been adopted successfully in several new types of aircraft. Besides, CGI also plays an important part in the development and transfer of engineering application systems. Finally, some application examples are given to demonstrate that CGI, as one of the most important basic tools for CAD / CAE / CAM applications, is an advanced graphics user interface with universal function.

Key words: graphics interaction, dynamic transformation, event handling, kernel technology
