Draw a motion path in 3D?

is there any way to use the pen tool to draw a mask in 3D and then convert it to a motion path? I want my particles to swirl around a layer and I dont want to keyframe the entire thing...

I was just about to post about something like this. You can draw a regular circle, attach it to a null, then change the orientation of the null and it will swing around in 3d space.

Not sure if this is what you're looking for (found on adobe's help site):

Create a motion path from a mask, shape, or paint path

You can create a motion path from any of several types of paths:

  • A Mask Path property

  • A shape Path property on a shape layer

  • A Path property for a paint stroke

  • A path copied from Illustrator or Photoshop

  • You can paste any of these paths into the Position or Anchor Point property for a layer, or into the position property of an effect control point. The pasted keyframes are set to rove in time, except for the first and last ones, to create a constant velocity along the path.

    By default, the duration of the pasted motion path is 2 seconds. You can adjust the duration by dragging the first or last keyframe in the Timeline panel.

    1. Copy a path to the clipboard:
  • Select a Path property in the Timeline panel, and choose Edit > Copy.

  • Select a path in Illustrator or Photoshop, and choose Edit > Copy.

  • 2. In the Timeline panel, select the property into which to paste the path. The property must be animated—that is, it must have at least one keyframe or an expression.
    3. Place the current-time indicator at the time for the first keyframe of the motion path.
    4. Choose Edit > Paste.

    Hope it helps :)
