Transform: order decides what turns

Transform moves, turns or scales a layer. Above Array it turns each copy; below Array it turns the whole row.

Try this

  1. In Demo 3, open Modifiers and drag Transform's handle above Array. Each copy turns, as in Demo 2.
  2. In Demo 4, click Transform and drag Pivot Y. The row swings around the new point.
  3. Press play. Demo 5 keys only Pivot Y, and the row swings back onto Demo 3.
