Abstract
A route determination support device enables target point to be navigated according to ratsnest with respect to reliable outline route, thus causing wiring to be formed approximately for the route which is intended by the operator finally. The route determination support device (ratsnest display device) consists of a singularity point position calculator for calculating the singularity point representing inputted outline route, a singularity point storage unit for storing therein the singularity point calculated by the singularity point position calculator, and a target point calculator for selecting a point with the most shortest distance from among the calculated distances as the target point, while calculating distance between the position of the stored singularity point and the present position in the inputted wiring operation.
