# How do I create a 360 degree revolving object that loops

I am trying to animate a layer around a globe like an orbit effect.
Normal orientation properties like x,y,z don't allow me to create a perfect circular motion path or continually loop it.
What do I do?

Parent the layer to a null layer and rotate the null. The distance from parent to child will be the radius of the circular orbit.

thanks
i tried that
but how do i animate the null object around a beizer circle
i want the object to stay flat.

Just FYI, if you start a line in this forum with a lowercase "i", the forum takes that as a code for italics. For more details, look right above the box provided for composing your message.

If you want the object to move in a perfect circle, using a null as a pivot will do the trick without having to create a circular motion path. Simply place the null at the center of gravity of the globe, parent the layer to the null, offset the layer from the null by the orbital radius, and rotate the null.

When you say you want the object to stay flat, what do you mean?

I suppose he's referring to keeping it oriented to the camera to retain the illusion. For that, use the Layer --> Auto-Orient options (shortcut Ctrl+Alt+O).

Ya, what i mean is having an object just move on X and Y co-ordinates around in a circle and not rotate on its own axis. Lets say the object is a flat layer with the 3D box ticked. It says AB on it. I want that flat layer to rotate around a globe and still have that flat plane visible, (still be able to see AB flat but obviously dissapears behind the globe. So no rotation of its own axis what so ever.

Don't worry.
I think I will use apple motion.It is better with 3D!
