Portal 2 Puzzle Maker/Piston Platform

Piston Platforms are testing elements in Portal 2. They move in vertical or horizontal lines on its own or when activated by another object, depending on the set properties (see below).

When placing a Piston Platform in a map, up to four arrows appear around it, depending if there is space available around the Platform. Clicking and dragging these arrows will produce the rail the Piston Platform moves on. The Piston Platform itself does not have to face upwards, its orientation can be changed by dragging the adjustment gizmo that is overlaying the Platform.
