How to 1:1 mirror more than 1 object?

Hello, i searched for mirror of more than one object but couldn’t find a solution which 1:1 copied/mirrored the selection.

Is there a way in Blender to 1:1 mirror/copy a selection of more than 1 object? If i try the solution or mirror with a 3D cursor pivot point my objects always end up with a different angle.

A mirrored object is influenced by the objects origin point (the center point of the mirror) and the rotation of the object.

You can also use another object as a mirror center (like an empty)

Temporarily join selected objects Ctrl-J, apply rotation Ctrl-A -> Rotation, establish new Origin/mirror point. Duplicate joined object Shift-D, Ctrl-M (xyz) mirror it and separate by loose parts mirrored objects in edit mode, P.

For multiple objects, use an empty as a mirror object as DCBloodHound suggests. Like so: mirrorobject.blend (583 KB)

Apply your objects rotation before adding mirror modifier. Ctrl + A > rotation

Actually if you’re using an empty as the mirror your object’s rotation no longer matters. The empty’s rotation does though.
