# AutoCAD TUTORIAL: Chapter 2 Drawing tools > Offset command

AutoCAD has a wide library of commands. There are many commands which used to drawing any type of drawing. Today i am going to tell you about various method to drawing offset in AutoCAD.

### Offset command:

Short key: O
Offset command is used to create concentric circle, parallel lines and parallel curves.
Offset creates a new object whose shape parallels the shape of a selected object. Offsetting a circle or an arc creates a larger or smaller circle or arc, depending on which side you specify for the offset.

Method to create offset
Select the offset command by press short key O enter.
Now specified offset distance. It is the distance between original object and offset object.
After it select the object to which you want to offset. Remember that this command is work only on polyline or the object which are made in single run.
Then select the side where you want to offset.

Example:
Create to parallel line which has a distance 1 between them

Solution:
O enter
1 enter
Select the line
Click the right of line.
Esc

When you want to create more than one offset at the same offset distance then choose multiple offset.
Method of creating multiple offset
Select the offset command by press short key O enter.
Now specified offset distance. It is the distance between original object and offset object.
After it select the object to which you want to offset. Remember that this command is work only on polyline or the object which are made in single run.
Now press M enter to choose multiple offset.
Then select the side where you want to create offset and press the left click of mouse as many time as you want to create offset.

Example:
Make 5 concentric circles in which inner circle have radius 5 and distance between two circle is .5

Solution:
C enter
Select a point in drawing area.
5 enter
O enter
.5 enter
Select the circle
M enter
Press left click of mouse four times outside the circle.
