Freerouting is an advanced autorouter for all PCB programs that support the standard Specctra or Electra DSN interface.
It basically does this:

## What has changed?
Freerouting is a fantastic piece of software. But the code hasn't been updated in a while and had some design flaws. Some of them are fixed now. This version of freerouting has been refactored to be fully compatible with JDK9.

This software can be used together with all host PCB design software systems containing a standard Specctra or Electra DSN interface. It imports .dsn-files generated by the Specctra interface of the host system and exports Specctra session files.(There exists also an interface to Cadsoft-Eagle.)
There are three modes for routing traces: 90 degree, 45 degree and free angle. The eu.mihosoft.freerouting.interactive router is production stable and unsurpassed in its free angle capabilities. An autorouter is currently under development and already stable in the conventional 45 degree mode.

After launching the router a window appears with buttons to display some router demonstrations, to open a sample design, or to open a design of your own.
After opening a design you can start the autorouter with the button in the toolbar on top of the eu.mihosoft.freerouting.board window.

The board editor has three different interactive states. You can switch between this states with the buttons Select, Route and Drag on the left of the toolbar.
In the beginning the eu.mihosoft.freerouting.board editor is in the select state. In this state you can select single eu.mihosoft.freerouting.board items by picking them with the left mouse button or select items in a rectangle by dragging the left mouse button. Only item types switched on in the select parameter sheet will be selected. After selecting some items the toolbar displays options for showing and manipulating these items. If you push the info button for example a window with text information about the selected items is displayed. After clicking a blue word in this text a new window with further information pops up. To return to the select state push the cancel button or click somewhere in the empty space of the eu.mihosoft.freerouting.board window.

By pushing the Route button you get into the state for eu.mihosoft.freerouting.interactive routing. In this state you can start a new trace by picking an item belonging to a net, for example a pin. Then you can follow the displayed airline with the mouse until you have reached the target item at the other end of the airline. The trace will be connected automatically to the target, if it is on the same layer. If you want to change to a different layer during eu.mihosoft.freerouting.interactive routing, select "change layer" and then the name of the new layer in the popup menu under the right mouse button. Then a via will be inserted, if that is possible, and a new trace starts on the new layer. You can also change the layer by pressing a number key.

Then a via will be inserted, if that is possible, and a new trace starts on the new layer. You can also change the layer by pressing a number key.
After pushing the Drag button you get into the state for changing the location of vias, components or traces. In this state you can select vias or components and drag them with the left mouse button to a different location. The connected route is updated automatically. You can also move traces by pushing them from behind out of the empty space with the left mouse button pressed. That works on the current layer, which can be changed in the select parameter sheet. In this way you can make space for example to insert a new component.
