Wire harness design aiding apparatus, method and computer readable recording medium storing program

A method of aiding designing a wire harness including a main line and a branch line manufactured by using a wiring jig plate, the method comprising the steps of:

• three dimensionally displaying, on a CAD display, an object on which the wire harness is to be arranged;
• arranging the main line to the object on the CAD display;
• constraining two points of the wire harness to the object;
• setting, based on a constraining direction of the wire harness with respect to the object, guide lines which are intersection points of a guide plane which is parallel to the wiring jig plate and extends passing the axial line of the main line and an outer surface of the main line,
• displaying the guide line on the CAD display;
• designating a desired position at which the branch line is branched out from the main line;
• setting a branching angle between an axial line of the main line and an axial line of the branch line;
• and
• setting an inclination angle between the axial line of the branch line and the guide plane to a predetermined angle or smaller.
