    • A Computer Aided Design (CAD) system with a dimension line editing function manages a drawing involving dimension lines and displays the drawing on a display unit connected to a terminal. The system edits the drawing according to a specified one of the dimension lines. The system has a setting unit for interactively setting an objective dimension line through the terminal; a retrieving unit for retrieving, in the drawing, dimension lines that are in parallel with the objective dimension line; and an editing unit for editing drawing data corresponding to the objective and parallel dimension lines according to a change quantity entered for the objective dimension line. The CAD system only asks a user to specify an objective dimension line to be edited as well as a change quantity applied to the dimension line. According to the specified data, the CAD system edits drawing data corresponding to the objective dimension line as well as drawing data corresponding to dimension lines that are parallel to the objective dimension line. This CAD system never asks the user to specify endpoints of the dimension lines to be edited one by one, so that the user can efficiently edit drawing data involving many dimension lines.
    • 具有尺寸线编辑功能的计算机辅助设计(CAD)系统管理涉及尺寸线的绘图,并在连接到终端的显示单元上显示绘图。 系统根据指定的一条尺寸线编辑图纸。 该系统具有用于通过终端交互地设置客观尺寸线的设置单元; 检索单元,用于在图中检索与客观尺寸线平行的尺寸线; 以及编辑单元,用于根据对于目标尺寸线输入的改变量来编辑对应于物镜和平行尺寸线的绘图数据。 CAD系统仅要求用户指定要编辑的客观尺寸线以及应用于尺寸线的更改量。 根据指定的数据,CAD系统编辑对应于目标尺寸线的绘图数据以及对应于与目标尺寸线平行的尺寸线的绘图数据。 该CAD系统从不要求用户逐一指定要编辑的维度线的端点,以便用户能够有效地编辑涉及多维尺寸线的绘图数据。
