Using the Arrow Connections
To wire up devices, instead of drawing a polyline, you can also use an arrow.
Here's an example:
Choose the Connect Tool and select the Arrow Mode icon in the mode bar. When you click on an output in device A an Arrow pointer appears and as you hover over inputs the corresponding connection arrow is shown. Click the input of device B to complete the connection and add a circuit..This connects device B input to device A output.
Arrow-style circuits are very useful when you have a large drawing and devices are far apart. They help you avoid visually confusing situations where you have multiple lines running all over the drawing. Instead you can have beautiful readable drawings.
