METHOD FOR MANUFACTURING LINE STRUCTURE HAVING AT LEAST ONE CABLE HARNESS

PROBLEM TO BE SOLVED: To provide a line structure forming method capable of forming a perfect line structure using a data processor. SOLUTION: (a) A design for a mechanical structure is displayed as an image by a data processor, (b) a connection plan for an electric system in the form of a line data set is combined with the display of the mechanical structure, so that a connection element can be displayed between equipment and a connection line, (c) a line passage is set in the display of the mechanical structure via an operator and the connection line is arranged in the line passage, (d) the setting and arrangement performed by Step (c) are checked about collision with given mechanical and/or electric restriction and the collision is displayed, and (e) the display of the line passage with the perfect arrangement of the connection line and the line passage is further used as a design for one or more cable harness with the connection element after Steps (c), (d) are repeated.
