Profile revising method

Abstract

When a figure element (S.sub.1) of a profile (A.sub.0) displayed on a CRT is revised to a figure element (S.sub.1 '), a processor causes a revised profile (A.sub.0 ') that does not include corner shapes (E.sub.1, E.sub.2) to be displayed on a display screen and subsequently inserts the corner shapes (E.sub.1, E.sub.2) in the revised profile (A.sub.0 ') in order one at a time. If an error is generated at this time, or in other words, if it becomes impossible to insert a corner shape, a message (M.sub.1) relating to the dimensions of the corner shape (E.sub.1) at which the error has occurred is displayed on the display screen CRT to make revision possible, and the corner shape (E.sub.1) at which the error has occurred is displayed in a color different from that of the other portions of the profile. By revising the corner shape (E.sub.1) at which the error occurred, the revised corner shape is inserted in the new profile (A.sub.0 '), which is displayed.
