Title: Dimension line editing method
Inventor: OZAWA AKITO
IPC: G06F17/50
Filed: 1994-04-25
Abstract: PURPOSE:To facilitate the designation of the filling-in system of a dimension line when the dimension line is additionally filled in and to improve the efficiency of the correction work of the dimension line by judging the dimension filling-in system of the dimension line designated from the feature of the arranged state of other dimension line which succeeds the designated dimension line. CONSTITUTION:When the additional filling-in of the dimension line is required since a graphic element 21 is corrected, a cursor 23 is moved on the dimension line in the same system as the system of the dimension line which an operator adds. When it is hit, the designated element is judged to be the dimension line or not. When it is a dimension line element, the dimension line element of a group to which the designated dimension line belongs is extracted. When the extracted dimension line element is the dimension line element filled in serires, the routine of series dimension filling-in is executed from the fetch processing of a next measurement point. When it is judged to be the dimension element of parallel filling-in, the routine of parallel filling-in is executed from the fetch processing of the next measurement point. Thus, the dimension line matched with the dimension line which is previously filled in is generated by designated filling-in.
