PLANAR MANUFACTURING DRAWING PRODUCTION SUPPORT DEVICE, PLANAR MANUFACTURING DRAWING PRODUCTION SUPPORT METHOD, PLANAR MANUFACTURING DRAWING PRODUCTION SUPPORT PROGRAM AND BRANCH ANGLE DESIGN SUPPORT DEVICE

The present invention aims to improve accuracy of a planar manufacturing drawing used to instruct manufacture of a three-dimensional structure in a planar form. According to path plan information is acquired by a path plan information acquisition unit 11a and manufacturing requirement information is acquired by a manufacturing requirement information acquisition unit, a layout configuration production unit 11c produces a layout configuration model in which the three-dimensional structure is laid out in a planar manner based on a manufacture layout and distortion of the wire harness. Then, a simulation unit 11d simulates a transformation from the layout configuration model to the mounting configuration model with which the three-dimensional structure is mounted to a mount object. Then, an evaluation item evaluating unit 11e evaluates a predetermined evaluation item by comparing the simulation result and the three-dimensional structure indicated by the path plan information. Then, an evaluation result information output unit 11f outputs the evaluation result to support path designing of the three-dimensional structure and/or production of the planar manufacturing drawing.
