I think this will work as long as you don’t go past 48 degrees or so (not sure if that’s an issue):

a = degreesToRadians(rotation);
len = (thisComp.height/2)/Math.cos(a) - (value[0]/2)*Math.tan(a);
[value[0],len*2]

Do you have it set up so that the Category layer doesn’t start at time = 0? If so, try changing this line:

b = L.sourceRectAtTime(time, false);

to this:

b = L.sourceRectAtTime(time - L.startTime, false);

[Dan Ebberts]

Understood. In playing around (and trying to guess how you have your comp organized) I couldn’t get the text to work until I made that change to your expression, after which I started getting expected results from sourceRectAtTime(), so there may be a connection.

I’m kind of shooting in the dark here, but it seems like this line:

if ((m.outPoint <= time) && (n.inPoint >= time)) {

should be like this:

if ((m.inPoint <= time) && (n.inPoint >= time)) {

[Dan Ebberts]

Can you post a screen shot of your timeline, showing how you have the layers arranged?

[Dan Ebberts]

I think all the parametric ones have match names that you could look for, like ADBE Vector Shape – Ellipse”.

>Is this normal?

No, it should copy all the text. There must be something else going on. Can you post a screen shot of how you have things set up?

[Dan Ebberts]

The only think I can think of would be to add a Scale Animation and set the Scale amount to your maximum size, add an Expression Selector (you can then delete the Range Selector) and add a Tracking property to the Animator so that tracking increases as the scale goes up. You might need to fiddle with the Expression Selector’s Amount expression if you don’t like how the size progresses from small to large.

Ah, I hadn’t noticed that your layers have been time stretched to 3.3%, so you’d have to factor that into the calculation of how long to set the duration of the source comp.

[Dan Ebberts]

This is very simplified and very specific to your example, but hopefully it gives you the idea:

var mainComp = app.project.activeItem;
var two = mainComp.layer("Two");
two.source.duration = 2;
two.outPoint = 3;
var three = mainComp.layer("Three");
three.startTime = 3;
var twoComp = two.source;
for (var i = 1; i <= twoComp.numLayers; i++){
	twoComp.layer(i).outPoint = 2;
}
