Abstract

An electronic information on a wire layout path is obtained based on an information on the shape of a wiring harness developed in a 2D plane; assisting jigs suited to the wire layout path are selected; an assembling table suited to the wire layout path is selected; and a 3D shape data of the assisting jigs 32 is read and located on an assembling table 23 together with 3D shapes of a wiring harness 19 and accessories 20, 21 in a virtual 3D space defined in a computer.

Claims
