AutoCAD Mirror

The mirror command in AutoCAD is used to create a copy (mirror copy) of the selected object. We can also delete the source object after mirroring the object.

The objects that represent the same as the half of their object can be mirrored across a center line to create the other half of the object.

It is shown in the below image:
