			== Number of air wires ==

			How many tracks do I have to rout? By the number of air wires you can say that. This number is shown in the layout dialog "Show air wires (ratsnest)" (from V20). Just press keyboard keys [Ctrl]+[w] to open this dialog.<br><br>

	Airwires are to be seen only in the [[layout]] view (PCB). They represent the electrical connections (signals) between [[pad]]s and often intersect each other. They are disentangled later by the use of the [[autorouter]] or by [[place tracks\|manual routing]]. A multitude of airwires are called ratsnest. A basic ratsnest might look like this:<br>		Airwires are to be seen only in the [[layout]] view (PCB).

	According to the standard settings of [[TARGET 3001!]] airwires appear in green. It is possible to adjust the color of airwires, controled by the edition of the [[signal]] which is the base for the airwire. There are two situations in TARGET 3001! where airwires appear:<br><br>		According to the standard settings of [[TARGET 3001!]] airwires appear in green.

	*Look at the end of the "orphan" airwire or look at the pad where it starts from: Are there any parts of tracks placed by accident?
