How to mirror objects in sketchup

Is there a way Like if you modeled the left side of the model and wanted the right side without manually modeling it

Make a ‘half’ of the object as a component.
Copy it to the side and mirror the copy, using scale -1 or the newer ‘flip tool’.
Move the copy to touch the first-half.
Now when you edit the first-half component the mirrored copy will show the same changes.
If you have abutting edges and don’t want them to be seen, hide them so the two parts appear smoothly joined…
