	Connections which are inflicted in breaks of rules are solved and can be showed as ratsnest (as far as you tick the box). Compute air wires new to receive ratsnest again (menu "Actions"). The settings in area "operational" are activated in later releases of the router.		Connections which are inflicted in breaks of rules are solved and can be showed as ratsnest (as far as you tick the box). Compute air wires new to receive ratsnest again (menu "Actions"). The settings in area "operational" are activated in later releases of the router.

	"Tactical" settings can be done to the right with two sliding buttons. The predefinition of a "preferable direction" makes sense only if you are moving upon two or more signal layers because vias only make sense in those cases. Both sliding buttons should nor be set to "forbidden" neither to "all the same". It makes sense to forbid a routing against the "preferable direction". Set the slider between "~~reluctantly~~" and "forbidden". The use of vias we leave on "~~reluctantly~~". So we don't wish them but we accept them.		"Tactical" settings can be done to the right with two sliding buttons. The predefinition of a "preferable direction" makes sense only if you are moving upon two or more signal layers because vias only make sense in those cases. Both sliding buttons should nor be set to "forbidden" neither to "all the same". It makes sense to forbid a routing against the "preferable direction". Set the slider between "doesn't matter" and "forbidden". The use of vias we leave on "doesn't matter". So we don't wish them but we accept them.

	To follow a "~~preferable~~ direction" allows parallel tracking of lots of tracks which - provided with vias - allow lots of tracks in orthogonal direction upon the opposite copper layer. As soon as one track is placed contrary to the ~~preferable~~ direction, ~~the~~ layout is divided into two sections and a routing beyond this track segment is not possible any more.		To follow a "preferred direction" allows parallel tracking of lots of tracks which - provided with vias - allow lots of tracks in orthogonal direction upon the opposite copper layer. As soon as one track is placed contrary to the preferred direction, it is like an obstacle. The layout is divided into two sections and a routing beyond this track segment is not possible any more.

	In the left area all project related copper layers are listed. Click upon a desired layer and set on the right side which signals and how they are to be routed upon that layer. You can reserve a layer especially for one single signal (e.g. GND or VCC, as often to be seen on the inner layers of multilayers) or close a layer for all signals. Compare the following picture from another project:<br>		In the left area all project related copper layers are listed.

	To the right please enter signal specific settings. The definition of the order has influence on the computing-heuristic. It is difficult to say which setting is best. it depends on the complexity of the layout. In this description we leave the standard setting. The standard settings in the fields ''Signal tracks'' and ''Vias'' show minimum settings in respect to the production opportunities. You can vary from those. The button "Default" recalls the standard settings.		To the right please enter signal specific settings. The definition of the order has influence on the computing-heuristic.

	If the routing result does not satisfy, delete it by dragging a square with M1 over the entire layout and press [Del]. If you have had routed some tracks manually prior to the routing process, those are not deleted unless you press [Del] once more. If you press [Del] once more and all tracks are deleted. Use the undo- function to get them back.		If the routing result does not satisfy, delete it by dragging a square with M1 over the entire layout and press [Del].
