  Align will not create new layers or copies of existing layers.

  Open the online help to Shape Layers, might be faster for you.

  Radio Waves can be used to create lots of circles (actually polygons with lots of sides).

  This can be done easily with Effect>Generate>Circle. You can have multiple circles on a single solid or, copy the effect to other solids and offset the center point of each new circle. I’m just getting started with them but you can also do this with expressions…though how you execute here depends on what you plan to do with the circles during the animation.

  Multiple circles on a single solid:
  1. Create a solid.
  2. Add Effect>Generate>Circle
  3. Set the radius and position of the first circle. Leave it’s blending mode as “None”
  4. Duplicate the effect, set blending mode to “normal”.
  5. Set the position of the circle numerically to align it with the first.
  6. Repeat steps 4 and 5 for each new circle you want.

  Single circle on multiple solids.

  As above but but for step 4, copy and paste the effect onto a new solid. Then do step 5.

  
  With expressions:

  1. Create a solid.
  2. Add Effect>Generate>Circle
  3. Set the radius and position of the first circle.
  4. Add expression to position property. value+[125*(index-1),0]
  5. Duplicate the layer however many times for the number of circles you want.

  The expression will move each new layer 125 pixels on the X axis multiplied by the layer number. This value can be edited to suit your needs. The expression also assumes that your first circle is layer 1, or index 1, in the comp…this number should be the layer number of your first circle.

  Good luck,
  Mark
