Abstract
A method for designing a structure or the like is provided in which an arbitrary curve is approximately drawn using a circular segment. This method includes the steps of: setting a straight line which connects one end of a desired curve and the other end thereof; setting an intersection point of the curve and a perpendicular to the straight line at a middle point thereof; obtaining a distance between the intersection point and the middle point, and a length of a straight-line segment from each of the one end and the other end of the curve up to the middle point; setting a curvature radius of a circular segment which approximates the desired curve in association with these distance and length, and acquiring a radius center point of the circular segment; and setting a circular segment from the one end up to the other end of the curve by using this center point as the center thereof.
