Delta parameter

After executing the Lengthen command, we are prompted to

Select an object or [DElta/Percent/Total/DYnamic]:

1. Lengthen a line

We can lengthen a line, arc, polyline, elliptical arc using the DElta parameter.

Please note: when prompted to enter delta length, we could enter a negative value to shorten the length.

2. Lengthen an arc

Another thing we can do with DElta parameter is to change angles of arcs.

Please note: when prompted to enter angle increment, we could enter a negative value to shorten the arc.

Total parameter

1. Specify the total length

We can stretch object from the endpoint that is nearest from the selected point to specified total lengthen

Specify the total angle

Percentage parameter

Dynamic parameter
