An editor in a CAD system, which assigns different command functions to each of a plurality of buttons, enables commands for editing processing such as "movement", "deletion", and copying" to be issued by the corresponding buttons, and adds one polygon and another polygon by a first button or subtracts them from each other by a second button and, further, even when one of the commands of editing processing is being executed, makes it possible to perform a "change", "cancellation", "confirmation", etc. of the mode of processing by operation of the corresponding buttons, thereby enabling change of a once input parameter or initialization of once input information, whereby the efficiency of work in pattern design using a pointing device can be improved.
