Abstract
Abstract When an item (T 1 or T 2 ) for revising chamfering or rounding is selected from a menu table (108b) of a tablet device (108), all corner portions (E 1 -E 3 ) included in profile (A 1 ) and pertaining to the revision item (e.g., the item for revision rounding) are displayed in a color different from the other portions of the profile. Thereafter, a corner portion (E 1 ) requiring revision is designated by a graphic cursor (K), whereupon the corner portions (E 2 , E 3 ) other than the designated corner portion return to the original color so that only the designated corner portion (E 1 ) may be identified for revision. .
