Harness verification apparatus, harness verification method and storage medium

A harness verification method that displays a harness route on a three-dimensional model of an object, the three-dimensional model being placed in virtual space, the harness verification method comprising:

• placing the three-dimensional model in virtual space and displaying a model plane on a display unit, the model plane being a plane onto which an overhead view of the placed three-dimensional model is projected;
• setting a plurality of reference planes in virtual space on the basis of reference plane data stored in an information storage unit and displaying cross-section projection planes on the display unit, the cross-section projection planes each being a plane onto which a cross section defined by intersection of the three-dimensional model and one of the plurality of reference planes is projected;
• obtaining a pointing position in virtual space on the basis of amount of movement of the pointing position, the movement being made by operating a pointing input unit;
• designating the pointing position as an operation position;
• changing vectors of the plurality of reference planes on the basis of the operation position and storing the reference plane data about the changed reference planes in the information storage unit;
• identifying the operation position as a pass point of a harness included in the object, generating one or more curve segments each corresponding to a section between two adjacent pass points when a plurality pass points are identified, and storing in the information storage unit definition information about a route of the harness defined on the basis of a curve obtained by joining the curve segments;
• and
• displaying a projection route of the harness on each of the cross-section projection planes, the projection route being generated on the corresponding cross section on the basis of the definition information.

A non-transitory storage medium that is readable by a computer and that stores a harness verification program causing a harness route to be displayed on a three-dimensional model of an object, the three-dimensional model being placed in virtual space, the harness verification program causing the computer to execute the steps of:

• displaying a projection image of the three-dimensional model on a display unit;
• storing design data and reference plane data in an information storage unit, the design data representing an arrangement and shapes of components included in the object, the reference plane data representing settings of a plurality of reference planes in virtual space;
• placing the three-dimensional model in virtual space and displaying a model plane on the display unit, the model plane being a plane onto which an overhead view of the placed three-dimensional model is projected;
• setting a plurality of reference planes in virtual space on the basis of the reference plane data and displaying cross-section projection planes on the display unit, the cross-section projection planes each being a plane onto which a cross section defined by intersection of the three-dimensional model and one of the plurality of reference planes is projected;
• obtaining a pointing position in virtual space on the basis of the amount of movement of the pointing position, the movement being made by operating a pointing input unit;
• designating the pointing position as an operation position;
• changing vectors of the plurality of reference planes on the basis of the operation position, and storing the reference plane data about the changed reference planes in the information storage unit;
• identifying the operation position as a pass point of a harness included in the object, generating one or more curve segments each corresponding to a section between two adjacent pass points when a plurality pass points are identified, and storing in the information storage unit definition information about a route of the harness defined on the basis of a curve obtained by joining the curve segments;
• and
• displaying a projection route of the harness on each of the cross-section projection planes, the projection route being generated on the corresponding cross section on the basis of the definition information.
