Creating a child map (sub-map)
- Switch to Designer mode.
- Add a "Network object" icon (see the image below) on the same way as you add a device icon.
- Double-click the icon of the new Network object.
- The child map opens
- Monitor one automatically adds a network object at the upper left corner of the new (child) map. Double-clicking this icon lets you return to the parent map!
