A computer-readable recording medium stores a program causing a computer to execute a data processing process that includes designating one plane data from a plane data group representing predetermined part data among part data expressed three dimensionally; setting at a position between a plane indicated by the designated plane data and a facing plane that faces the plane and is indicated by plane data other than the designated plane data, a first set plane that faces the plane; setting at a position on an opposite side of the plane from the facing plane, a second set plane that faces the plane; and acquiring projection control information for projecting in a projection direction from any one among the first and second set planes toward the other set plane, a part group located between the first and second set planes and indicated by a part data group among the plural part data.
