Point Set Edit
The Point Set Edit tool can be used to be place either control points or way points throughout the volume. This tool allows you to place points on the volume. To stop placing point, click on the navigate button. To place a new point, use the left mouse button. In order to remove points, hold shift and left click on the point you wish to remove. For this tool to become available, you must either open an existing point set or create a new point set.
Point set edit mode is located just above the layer list and underneath the menu bar, or can be found under Action -> Point Set Edit in the menu bar. Alternatively, you can use the shortcut key Ctrl+T.
