Use to create a simple breakout pattern in a footprint (for example a PGA). The breakout will consist of an angle breakout track ending on a via, for each surface mount pad in the footprint.
Use in a PCB design to create a simple fanout pattern of tracks ending on a via, for each surface mount pad on the selected component. If the component already has breakouts, then you will not be able to use this option. A surface mount pad must be on a net for the track to be added into the design, and pads that already have a routed connection will not be included.

Create Breakout Pattern
Define the X and Y offset of the breakout relative to each surface mount pad. You can reverse the direction by specifying positive or negative values.
Radiate from centre causes the direction of the breakout to be determined from the position of the pad relative the centre. The centre is defined as the centre of the bounds of the pads on that side, or with the From Symbol Origin checked, the Symbol Origin. The X, Y offsets defined are adjusted accordingly.
Apply to Selected Pads Only, when checked, will add breakouts only to the selected pads.
Select the Track Style to use for the breakout. Then select the Via Style, only pad styles defined as suitable for vias are shown. Usually you would select a style already defined in the technology.
Footprint Only Options
Automatically convert to Track (when pad is on a net) can be turned off to stop the breakout from ever “automatically” being converted to a track. This option is only available in a footprint.
Convert to Track on unconnected Pads can be switched on to allow breakouts attached to pads that are not on a net in the PCB design to “automatically” be converted to tracks. For more information see Track and Via Breakouts. This option is only available in a footprint.
Press Apply to generate the pattern without leaving the dialog.
The pattern generated will replace any existing breakout patterns on the surface mount pads.
