How can I mirror objects in Blender versions 2.30 and above?
I know that you can mirror vertices in mesh edit mode, by using the M key, but I don’t know how it can be done in the object mode.

SKEY for scale
then type -1 (keyboard, not NumPad) to give a negative scale
type XKEY followed by -1 to flip in X

How come you need to do the mirroring in object mode? Shift D in object mode to duplicate, enter edit mode, and ‘M’. Also, there may be a better answer,…questions regarding duplication have been asked alot lately, so if you do a quick search, I’m sure you will find plenty on the topic.
<edit> ack,…listen to S68,…he knows what he’s talking about.
Because you can have duplicates that share the same mesh, if one of them is miorred you can work on an object by only editing half
there is a better “virtual mirror” function in wings, but having a flipped duplicate works very well in blender (and doesn’t have workflow issues when trying to add detail along the seam, there are no new restrictions added)
Thanks!
I asked this, because I tought there was a new way to do it (without the scaling “trick”).
In http://www.blender.org/docs/2.30_release/2.30.html it says about the new flipping:
- Flipping sizes
The old convention was that pressing X, Y or Z flipped the axes while in Scale mode. This has been solved with two new options:
- in Edit Mode, pressing MKEY will provide a menu with choices.
- Object Mode…
So I got the impression that there is some new way to flip objects in the object mode, but the guy who wrote that document forgot to update info about it.
It was also asked in bug reports but the author was simply told he should read the release notes and ask here.
And yes, I did do the flipping in the edit mode, but I wanted to know easier way for the future. You never know when you end up in the place where you have 50 separate objects to flip.
Do you get a black shading on the object when having shading enabled in the viewport after mirroring only on one axis?.. I do… and it’s halfway annoying. Specially when it renders perfectly fine 
That’s an openGL problem and is the reason why the Mirror menu (M) doesn’t work in Object mode. Until a fix is found that is.

ok, thanks for clearing that out 
Actually I think I fixed this by recalculating the normals…pretty sure thats how I fixed it…cant really rember now…that or maybe the “double sided” option (as funny as that may sound)…cant remember. Let me know if it works.
Cheers,

Yes, double sided fixs this. However, if your mesh is not closed. all the inside will appear black.
