PROBLEM TO BE SOLVED: To provide a cube development creating method, device, and a computer program which enables automatic creation using a computer. SOLUTION: This system is provided with the first process, which extracts coordinates 1, 2, and 3 which compose a cube; the second process which extracts side A and C, which consist of greater or equal to three apexes and are associated with the apexes; the third process which extracts an edge line E3, which is on the boundary of adjoining two sides A and C and forms an edge and is associated with each side, the fourth process which develops the side by transforming the coordinates 1, 2, and 3, which composes the side A to be developed, to two dimensional coordinates 1', 2', and 3'; and the fifth process which decides a side C', which is adjoins the developed side and is to be developed next, according to the edge line E3' which composes an edge of side A' developed by the forth process. The forth and fifth processes are repeated in this order until all the developable sides are developed.
