Hi
I need to know how to do the following:

I have a piece of text which I like to switch around/twirl around to reveal another piece of text.

Could you let me know how to do something like that.

Much Appreciated

When you say switch around/twirl do you mean that it rotates on one of it's axis 180 degrees and on the reverse side is a different word?

If that's the case, create both text layer and place the anchor point in the center of the text layers. Enable 3D for each layer and animate/keframe the rotation of one layer 0 to 180 degrees on it's X or Y axis. Parent the 2nd layer to the first. Now as you scrub you should have a back and front layer.

Now open your opacity controls(T)and alt-click the stopwatch to enable expressions and paste this expression: if (toCompVec([0, 0, 1])[2] > 0 ) value else 0. It turns off visibility of layers that aren't facing forward.

To learn more about this expression go to http://motionscript.com/design-guide/invisible-facing-away.html
