Command line: LEN, LENGTHEN
Using the Lengthen command you can change the central angle of arcs and the length of lines, arcs and open polylines. The length or angle of objects is changed on the side closest to the specified point or on both sides simultaneously. The length or angle of the same object can be changed several times whilst one command is being performed. If a value is positive, the arc is lengthened, if a value is negative – the arc is shortened.
Command options:
? Opens the additional options to select objects.
DElta The value of the object’s length is changed.
The option opens the prompt in the command line: Enter delta length or [Angle]:Option:
+Angle+-The value of the object’s center angle is changed.
Percent The object’s length as a percentage of the source length.
Total The total length or center angle.
The option opens the prompt in the command line:
Enter total length or [Angle]:
Option:
Angle -The value of the object’s center angle is changed.
DYnamic Dynamic change of the selected object’s length by replacing the endpoint closest to the selection point with the fixed position of another endpoint.
