Changing Local Axes? It's likely I'm missing on some fundamental understanding here.



I'd like to change the planets' local axes to match the global.  So in Object mode, I rotate Z90.  So far so good.

I thought the next step would be to Apply the Rotation change.  However, Apply changes the rotation back to default.

Can someone explain what I'm missing here?
Got it!

The problem was I had all the planets Parented to an empty at the sun's position.  

Once I unparented the planets, I was able to Apply the change and have it stick.
