A method and an apparatus for providing easy alignment of two surface shapes of a three-dimensional object, obtained from different directions of line of sight. There are executed data entry of the two surface shapes, and initialization and storage of the direction of line of sight in the projected display of the surface shapes. The variables define the position and direction of the surface shape, and the position of a section plane for the surface shapes, to display projected images and section images. The setting of the position and direction of the surface shape and the position of the section plane is changed, thereby aligning the surface shapes, and, after the alignment, the amounts of translation and rotation of the surface shape is released.
