    This paper describes the background and research for a diagram sorting and analysis system called GIDA -- Graphics Interpreter of Design Actions. The GIDA system explores how spatial relations between graphic symbols in a design drawing may be extracted and the transformations of the graphic elements between different drawings in a design process may be tracked.
