What is the purpose of the "LENGTHEN" command?

The purpose of the "LENGTHEN" command in AutoCAD is to change the length of an object. This command allows users to extend or shorten lines, arcs, and polylines by specifying a new length or modifying their dimensions directly.

When using the LENGTHEN command, you can input a specific length, and AutoCAD will adjust the selected object accordingly. This is particularly useful in situations where precise measurements are necessary, as it provides a quick way to manipulate the size of objects without altering their overall shapes or angles.

The other options may describe related functionalities in AutoCAD but do not accurately capture the specific function of the LENGTHEN command. For instance, simply creating a longer version of an object implies duplication rather than modification, while stretching an object along its path refers to a different action, typically associated with the STRETCH command. Measuring the distance between two points relates to dimensioning and does not pertain to changing the object's length directly. Thus, understanding the precise role of LENGTHEN is essential for effective drafting and design in AutoCAD.
