PROBLEM TO BE SOLVED: To provide a combination screw plotting program for CAD system, capable of rapidly plotting a combination shape of a screw part, and a recording medium recorded with the plotting program. SOLUTION: The combination screw plotting program for CAD system comprises step 6 of temporarily plotting a screw with a bearing surface consisting of one outer shape line located at the outermost side and a screw tip turned to the other outer shape line; step 7 of extending and contracting the underhead length by making the user locate a cursor at the tip of the temporarily plotted screw and move the cursor in the axial direction of the screw; step 14 of displaying a selection screen for making the user designate a screw part to be combined with the tip part of the screw; and step 15 of plotting the screw part designated by the user by determination operation in combination with the tip of the screw. The recording medium is recorded with this plotting program. COPYRIGHT: (C)2007,JPO&INPIT
