The MIRROR Command in AutoCAD Will Reflect Objects About A Defined Line
Use the MIRROR command to mirror one or more objects. Mirroring objects can be performed at any mirroring angle. Most commonly, mirroring objects is done about either a horizontal line or a vertical line, however AutoCAD allows mirroring to be performed at any mirror angle.
Initiate the MIRROR command and select the objects to be mirrored. Next, select the point at which the objects will be mirrored about.

Next, select the second point of the mirror line. In the image below, the objects selected are being mirrored about a vertical line.

In the image below, the same objects are being mirrored at a random angle. All objects are still a mirror of the original objects and are being created at an angle other than what is traditionally thought of when mirroring.

When the Second Point of Mirror Line has been entered in the Dynamic Input, AutoCAD asks if you would like to erase the source objects. Entering Yes will erase the source objects and entering No will leave the source objects and create the newly mirrored objects.
