1. An additive manufacturing path generation apparatus comprising:
formation path generation circuitry to divide an additive manufacturing object into layers that are units of formation of the additive manufacturing object such that a formation height of a bead for each of formation paths that are paths for formation of the layers does not exceed an upper limit and generate the formation paths from layer definition information and a formation path surface, the layer definition information defining division of the additive manufacturing object into the layers, the formation path surface being a surface restricting positions of the formation paths; and
formation path correction circuitry to correct the formation path such that the formation path corrected at least in part includes a portion where a plurality of the layers before correction are collectively formed, and that the formation height for the formation path corrected falls within a range between the upper limit and a lower limit.
