    • PROBLEM TO BE SOLVED: To process a metallic sheet into the target shape even when it is the target shape the principal curvature of which can not be specified and also to manufacture manufactured goods having stable quality without needing a skillful technique for working it.
      SOLUTION: A bending method is disclosed for manufacturing the manufactured goods having the target shape by deforming a bending member by heating the surface of the bending member. The bending method comprises: a line segment setting step where geodesic lines and segments orthogonally crossed with the geodesic lines on the surface of the target shape are set; full-scale drawing developing step where the target shape is developed on a full-scale drawing; heating position determining step where the heating positions are determined by using the geodesic lines and the line segments after developing the full-scale drawing and the geodesic lines and the line segments set on the target shape; heating position setting step where the heating positions are set on the surface of the planar bending member; and heating step where heat is applied to the heating positions.

    • PROBLEM TO BE SOLVED: To provide a CAD system which remarkably improves the use value of a CG model or a CAD model and realizes efficient design/production processes, and a curved surface analysis device, a curved surface reproducing device, and a method and a program therefor. SOLUTION: A computer maps a curved surface on an actual space to a parameter space and calculates a primary base quantity and a secondary base quantity. Next, the computer calculates the curvature line of the curved surface and actual space coordinates where the curvature line passes, and calculates actual space coordinates of an intersection on the parameter space, between a line passing an inverse mapping target point on the parameter space and the curvature line mapped on the parameter space. Then the computer calculates a curve on the actual space, which passes the calculated actual space coordinates of the intersection and calculates a actual space coordinate value of the inverse mapping target point on the curve and thus reproduces curved surface data on the actual space.
