Is there a simpler way of doing this? Trim Paths on a Ellipse doesn't give the shape I want.

I'm using two rectangles to subtract from the circle.

You could create your pie pieces in Illustrator and then import as a composition or copy/paste them into a shape layer. This would also give you the ability to divide up the pie chart portions in the exact amounts you are looking for.

If this doesn't make sense let me know. I am not the most proficient at illustrator but could give you basic steps how to do this.

I thought of that. But I think I need shape layers so I can animate the size of the wedge (1/4 to 2/3's wedge).

Tried Radial Wipe, but it's a 3D layer so the effect goes wonky when I collapse transforms in another comp.

Hmmmm. I'll have to give this some more thought. In the mean time...

I haven't used BorisFX "Red" but it claims to have this ability to animate pie charts.

or

I did find this script that builds pie charts. It allows you to animate from one percent to the other and move that 2D shape 3D. It doesn't appear to give you the ability to have any extruded depth to your shape.

You should look at using Merge Paths, NOT Trim Paths. Another important tip is to re-position the Anchor Point for the Rectangle Shape prior to animating its rotation since you will want the rotation to be anchored to the center of the circle.

I think I may have found the simplest way to do this. Start by creating a Shape Layer with the ellipse Shape Tool. Remove Fill and set the value for Stroke until the ellipse is filled by the stroke width/color. Then apply Trim Paths and you're set to go.
