PROBLEM TO BE SOLVED: To provide a change work drawing generation/output device which can reduce man-hour by means of a manual operation for indicating an optimum cut position by considering a cut condition in the design change work of a printed wiring board containing the cut of a wiring pattern. ;SOLUTION: The change difference of logic information is extracted from the design file of the printed wiring board before and after the change and reads a change information file 5 based on the difference. Condition information in the cut is read from a cut condition file 6 and an electric condition in the cut position is checked. A physical condition in the cut position is checked from condition information and part information on a part information file 7. The change work drawing of the wiring pattern which is cut in the satisfied cut position is generated and outputted based on both checks.;COPYRIGHT: (C)1998,JPO
