PURPOSE:To automatically move other projection figures having restraint relation in position with an optional moved projection figure in a projection figure group to positions where restraint relation among the projection figures is held when the optional projection figure is moved. CONSTITUTION:When the projection figure group 53 is displayed in an image, a front elevation 53B is specified as the projection figure to be moved and when a movement vector V is set, the figure data of the front elevation 53B are updated according to the movement vector V. Further, the left side elevation 53A, right side elevation 53C, back elevation 53D, top elevation 53E, and bottom elevation 53F are selected as back elevations having the restraint relation in position with the front elevation 53B, and the movement vectors of those projection figures are calculated according to the movement vector V of the front elevation 53B. Then the figure data of the respective projection figures are updated according to the calculated movement vectors and updated images of the respective projection figures are displayed at positions shown by solid lines. |
