Abstract
A graphic editor for performing various editing processes such as inputting, moving, copying, and deleting a graphic pattern and a line on a display screen in a graphic editing system such as a CAD, etc. The graphic editor realizes a user interface for simultaneously selecting an object to be processed and a function, thus improving the efficiency of the editing operation. The editor comprises an area specifier for specifying an area as a rectangle having a diagonal whose start and end points are specified by the area specifier, and a graphic operating unit for determining the existence of a symbol or a line in a specified area to give a predetermined process on the symbol or the line. The predetermined processes can be identified by determining whether or not a symbol and/or a whole or a part of a line exists in or crosses a specified area.
