Abstract

PROBLEM TO BE SOLVED: To save the plotting labor and to reduce the production cost by automatically plotting a chamfer and the radii of circles touching the both sides of the chamfer for all charts consisting of ruled lines. SOLUTION: The chamfers and the radii of circles touching both sides of each chamfer are automatically plotted for all charts consisting of ruled lines. In such a method, every 1st chamfer 71 of an optional size and every 1st radius of circle 72 formed at both ends of the chamfer 71 are displayed at each of right-angled parts included in a 1st ruled line 58 to a 12th ruled line 69. For this purpose, a cursor is moved on a screen by means of a keyboard to designate and preserve the ruled lines 58 to 69. Then the 2nd right-angled parts are identified in the ruled lines 58 to 69 and preserved, and the coordinates of a 1st end point of each 2nd right-angled part are calculated and preserved. Meanwhile, the value of every chamfer 71 of an optional size which is drawn at every 2nd right-angled part can be inputted together with the value of every radius 72 which is formed at each of both ends of the chamfer 71.
