The tool box shows the items available that can be added to the Plan. A default set of items are supplied with the software, additional items can be added through the Template Manager.

An item can be added to the Plan graphically by clicking and dragging the item to the required location.

The one exception to this are Connections which cannot be dragged. To add a connection select "Add Connection" from the Plan right-click menu and join two items. The Connection template selected on the toolbox will be the one used when the connection is added.
