ABSTRACT:
The graphic elements which constitutes a graphic data created by a CAD system for processing the graphic data displaying a graphic formed by combining the graphic elements are sorted into separate attributes consisting of graphic type, color, line type, line width, and the like while are represented by coordinate which indicates the position to be located and configuration as well as by a range coordinate and recorded in comparison files which include tables where each attribute is assigned with the coordinate data. Accordingly, the comparison files can be used with higher effectiveness for comparing the graphic data between the different formats. Also, as the identity of graphic data is judged through the comparison in the number of tables and the number of graphic elements with respect to the attributes, the number of items to be compared will be decreased. Moreover, as the number to be compared is an integer but not a real number by which the coordinate is represented, the processing load such as processing time can be reduced in comparison to compare real number coordinates.
