cad中的直线怎么拉伸?

CAD

以下为方法的改写：1. 使用AutoCAD软件，在状态栏中点击“极轴”右击，在追踪处输入相应角度，确保极轴设置为凹下去，即打开状态。当绘制直线时，每旋转设置角度的倍数会出现虚线。直接输入直线长度后按回车键确认即可。

2. 点击直线的第一个端点，在命令行中输入@L followed by the desired length of the line (e.g. @L50) and then enter. This will create a line with a length of 50 units. Alternatively, you can also enter @L followed by the angle between the horizontal and the line (e.g. @L45) to create a horizontal line.3. To move a horizontal line (i.e., with an angle of 45 degrees), click on its first endpoint. In the Command Line Editor, type "D" (for "dimensions") then "A" (for "area") then "O" (for "offset"). Enter the desired offset value and press enter. Alternatively, you can also click on the first endpoint and enter the desired angle with which the line should be moved using the command "A" (for "angle"). After entering either offset or angle value, press enter to confirm the action.以上方法适用于AutoCAD软件，根据需求进行直线绘制与移动的操作。
