Ok, makes sense. Thanks Andrew.

Hi

You need to delete the copper fill zones before you export the DSN to FreeRouting.  Then FR will route all the traces including the ground traces.  Once you reimport the Specctra session into PCBnew you can add the copper fill zones which will then absorb all the ground traces.

Thanks and have a nice day!

 I’m new to FreeRoute – and
 having a few teething problems.  I’m wondering if anyone  here with more experience with FR can help me  out.  I’m working on a double-sided  board.  I successfully manually routed the whole board (way  too many hours spent on this!) and I’m now comparing my  manual results with FR’s capabilities.  There are copper  “zones” on both sides, to be connected to GND.  When I  route the board in FR, it doesn’t attempt to connect any  of the pins that are intended to be connected to GND.  All  other traces are routed correctly, in accordance with the  design rules (track widths etc) that I defined in KiCAD.  FR seems to assume that KiCAD’s GND “zones” will  connect all the GND pins, when the zones are later filled in  by Pcbnew.  The problem is that when Pcbnew (in KiCAD) does  fill in the zones, it can’t reach many of the required  pins, as FR hasn’t left any space for the zones to flow  between the traces that FR has laid.  Has anyone else had this  problem?  I’ve found a workaround (disconnect the zones  from GND, before running FR) but I assume there should be a  better way to do this?  Malcolm
