Changing the Length of Objects

Changing the Length of Objects
Suppose that, after finding the length of an arc, you realize you need to lengthen the arc by a specific
amount. Choosing Modify  Lengthen lets you lengthen or shorten arcs, lines, polylines, splines,
and elliptical arcs. As an example, here’s how to lengthen an arc:
1. Choose Modify  Lengthen, or type len↵.
2. At the Select an object or [DElta/Percent/Total/DYnamic]: prompt, type T↵.
3. At the Specify total length or [Angle] <1.0000)>: prompt, enter the length you want
for the arc.
4. At the Select an object to change or [Undo]: prompt, click the arc you want to change.
Be sure to click at a point nearest the end you want to lengthen. The arc increases in length
to the size you specified.
The Lengthen command also shortens an object if it’s currently longer than the value you enter.
In this short example, you’ve learned how to change an object to a specific length. You can use
other criteria to change an object’s length, using these options available for the Lengthen command:
DElta Lengthens or shortens an object by a specific length. To specify an angle rather than a
length, use the Angle suboption.
Percent Increases or decreases the length of an object by a percentage of its current length.
Total Specifies the total length or angle of an object.
DYnamic Lets you graphically change the length of an object using your cursor.
