The wire harness 2 dimensional development device, to straight line converting the wire harness which the distribution cord is done with 3 dimensional form of wire harness

摘要

PPROBLEM TO BE SOLVED: To develop a wire harness from a three-dimensional shape into a two-dimensional shape by minimizing the amount of deformation. PSOLUTION: When wire harness route information to be made into a straight line is acquired by a route information acquiring means 11a, a dividing means 11b divides the wire harness to be indicated by the route information into a plurality of segments. An end point in the movement of the segment is set as a development point, and the other end is set as a reference point by a setting means 11c. The curvature characteristic of the segment is detected by a curvature characteristic detecting means 11d. When a rotation axis setting means 11e sets a rotation axis for rotating a development point directional vector based on the curvature characteristic, a rotary angle detecting means 11f detects a rotary angle for rotating the development point around the rotation axis. The segment is made into the straight line when a developing means 11g rotates the development point directional vector around the rotation axis by the rotary angle and also the development point is moved onto the extension line of a reference point directional vector.
