How to Adjust Multiple Line Segments in AutoCAD

Autodesk AutoCAD is a powerful and widely-used software tool for computer-aided design (CAD) and drafting. Adjusting the length of line segments in AutoCAD is a common task that can be efficiently accomplished using the LENGTHEN command. This article will guide you through the process of adjusting multiple line segments in AutoCAD, including the use of options such as DELTA, TOTAL, DYNAMIC, and PERCENT.

Adjusting Line Segments Manually

If you need to change the length of a single line segment, you can do so without selecting the segment by directly inputting the desired length and pressing the Enter key. For example, if you know you want a line to be 10 units in length, you can simply type 10 and press Enter to extend or shorten the line.

Using the LENGTHEN Command in AutoCAD

To adjust the length of multiple line segments, the LENGTHEN command is very useful. To activate the LENGTHEN command, you need to type LEN and press Enter.

Options of the LENGTHEN Command

Once the LENGTHEN command is activated, you can choose from several options depending on your specific needs:

DELTA

The DELTA option allows you to specify an incremental or decremental change to the line segment's length. If you want to decrement or shorten the line, you can enter a negative value. For example, to shorten a line by 5 units, you would input -5.

TOTAL

The TOTAL option allows you to specify the exact new length of the line segment. This is straightforward; simply input the new length you desire, and the command will adjust the line accordingly. For instance, if you want a line to be 20 units long, you would input 20 using the TOTAL option.

DYNAMIC

The DYNAMIC option is more intuitive, as it allows the line segment to dynamically adjust its length as you move the cursor. Once you specify the new length with the DYNAMIC option, the line will accept the new length when you click on a desired location. This method is particularly useful for precise adjustments that you can visualize while making decisions.

PERCENT

The PERCENT option is ideal for making relative adjustments to the line segment's length. By entering a percentage, you can either increase or decrease the line's length by a specified percentage of its current length. For example, if you enter 120 (or any other percentage), the line will increase by that percentage. Conversely, entering a percentage less than 100 will decrease the line's length.
