In situations where poles are already drawn on the map but connections need to be added, particularly at intersections, the Join Aerial tool can be used to draw connection lines without adding new poles to the map.
To use the Join Aerial tool, start by clicking on the starting node that needs to be connected. Then select the green Join Aerial tool from the toolset. Once the tool is active, click on the adjacent pole to build the connection between the two points. You can repeat this process for all poles that need to be connected. When you're finished, exit the tool by right-clicking with your mouse or pressing Escape (Esc) on your keyboard.
