Drawing creation method, wire harness manufacturing method, and drawing creation device

A drawing creation device comprising:

• a drawing creator configured to create a drawing showing a wire harness configured with wires bundled together, the wire harness including:
• wire branch points where part of the wires branches off;
• and
• branch lines each extending from an end of corresponding one of the wires to corresponding one of the wire branch points;
• and
• an information acquirer configured to acquire information including following [1] to [5], the information acquirer including a scanner or a camera:
• [1] a path of the wire harness in a movable body;
• [2] a distance between the wire branch points;
• [3] a length from each of the wire branch points to a corresponding connection target of the wire harness;
• [4] identification information of the connection target of the wire harness;
• and
• [5] identification information of the connection target of each of the wires,
• wherein the information acquirer reads the distance between the wire branch points and the length of each of the branch lines through image recognition or character recognition from a vehicle drawing showing the path of the wire harness in the movable body, the vehicle drawing including information of the distance between the wire branch points, information of the length of each of the branch lines, and the identification information of the connection target of the wire harness,
• wherein the drawing creator is configured with a computer configured to create the drawing showing the wire harness, the drawing reflecting the distance between the wire branch points and the length of each of the branch lines, based on the information acquired by the information acquirer,
• wherein the drawing creator identifies a path of each of the wires in the wire harness by cross-checking the identification information of the connection target of the wires included in a wiring table against the identification information of the connection target of the wire harness included in the vehicle drawing, the wiring table including the identification information of the connection target of all the wires forming the wire harness, and
• wherein the drawing creator identifies the distance between the wire branch points and the length of each of the branch lines, based on the information read by the information acquirer.
