Abstract: An information processing device includes a receiving unit, an inspection unit, a generating unit, and an output unit. The receiving unit receives three-dimensional (3D) information at least including a 3D shape. The inspection unit conducts, on the 3D information, a mold requirement inspection at least including undercut as a mold requirement inspection for fabricating an object represented by the 3D information. When the inspection unit detects an inexpedient part, the generating unit generates inexpedience information for creating a 3D representation of the inexpedient part. The output unit outputs the inexpedience information in association with an inspection item.
