When two neighboring linear elements (1a, 1b) in a first figure (1) and two linear elements (2a, 2b) in a second figure (2) are designated, the intersecting point (P1) of the two linear elements (1a, 1b) in the first figure (1) is overlapped on an intersecting point (P2) of the two linear elements of the second figure (2), and the designated first and second linear elements (1a, 1b) of the first figure are overlapped on the designated first and second linear elements (2a, 2b) of the second figure, so that the first figure is superposed on the second figure. |
