PROBLEM TO BE SOLVED: To create an expansion plan for assembling a solid body by folding the expansion plan according to the polygonal line of the expansion plan without cutting or pasting plane raw materials from one plane.;SOLUTION: When a conic type expansion plan is created, a regular N-sided plane corresponding to the number of sides N of a rotary sweep-shaped solid body is used, and the plane is equally divided into N (S100 to S110), and the expansion plan obtained by opening the rotary sweep-shaped solid body in a rotary axial direction is arranged in each division area of the plan (S120). In each division area, a line extending from a side edge corresponding to the ridge of the rotary sweep-shaped solid body to the boundary of the division areas in parallel with the contour line of the rotary sweep-shaped solid body is set to an auxiliary line (S130). In each division area, the side edge corresponding to the ridge of the rotary sweep-shaped solid body is set to the first polygonal line of the expansion plan of the rotary sweep-shaped solid body. As for each contour line of the rotary sweep-shaped solid body, a line made by connecting internal points internally dividing the auxiliary line by a predetermined rate (1:1 in a conic type) is set to the second polygonal line of the expansion plan of the rotary sweep-shaped solid body (S140).;COPYRIGHT: (C)2012,JPO&INPIT
