Rotating around an anchor but keeping object upright
Hi all,
I have a set of shapes that i want to move around the screen but maintain its upright position when it is rotating.
At the moment I have put the anchor point in the centre of the comp but when I rotate the object, the shape turns with it. There is text within the shape that is why I want to maintain its upright position so it is easy to read.I hope this makes sense to anyone.
I found this example which might help you understand what I’m trying to achieve.

Assuming you arranged your shapes in the comp and parented them to a null object in the center of the screen. Open up the rotation property of of one your objects and “alt + click” to open the expression editor. Type in “-(” then pick whip to the null’s rotation property. Finally close the expression with another “)”. You should get this:
-(thisComp.layer("Null 1").transform.rotation)Simply you are telling your objects to rotate the exact opposite way the parent is rotating.
Here it is in action: 4411_rotationexpression.aep.zip

John,
Thank you so much for your time.
The effect you made is exactly what I want.
I applied the same expression to my image but my result was that it was rotating in an opposite direction but was not keeping upright like your text.Did I miss something?
Thanks again.

You need to explain your setup a bit more, when you say you applied the expression to an “image”, are you just working with one layer? The method I used works when you have multiple objects parented to a single controller in the middle of the comp.
If you have one layer, you would need to break the layer into individual components, parent them to a control in the middle of the composition(null) and then apply the expression.
