I got confused and drew all traces in the back face rather than the front one.
Is there a way to move one/all traces from one plane to another without having to redraw them one by one?
I couldn’t find anything in the user interface.
Edit the: “<project_name>.kicad_pcb” file.
All files in KiCad are ascii & human readable (and editable) text files.
The file formats are described here: https://kicad.org/help/file-formats/
Edit:
I just tried @eelik 's suggestion in KiCad V4.0.7 and it works for me.
I did:
1). In PCBnew, draw some traces with “x”, on both sides, place a via with “v”.
2). End button to end the trace, Esc to exit from the trace draw funcion.
3). Drag a box around the trace segments -> Right Mouse Button -> Properties -> Layer: -> F.Cu -> OK.
