6.0 RC1 - Track has unconnected end

I hereby certify that I am not simply asking someone else to design a footprint for me.

This is an auto-generated message that is in place on the “footprints” section of the KiCad.info forum. If I remove it and ask for a footprint to be designed anyway, I understand that I will be subject to forum members telling me to go design my own footprint or referring me to a 3rd party footprint site.

I’ve got a project that was done in 5.1.12. All DRC checks passed and I got the PCB made and populated and it all works as expected.

I’ve now upgraded to 6.0 RC1 and am getting an error when doing a DRC on the PCB.

I’ve tried removing the tracks and re-adding and can’t seem to get rid of this error. All 3 errors point to vias.

Could this be some bug in RC1. The track can’t be unconnected as the circuit works.
Why would the error point tot he via? Is it reporting it’s not connected?

All three errors are for very short track segments:

It’s a bit of an annoying bug / feature that KiCad makes these, and sometimes they get left behind.
If you draw tracks / via’s in "outline mode ( Pcbnew / View / Drawing mode / Sketch [xxx] then these short stubs become visible and you can select and delete them.

You can also use: Pcbnew / Tools / Cleanup Tracks & Via’s. I do recommend to be a bit careful here because this function sometimes deletes more then you wish for.


Thanks. Didn’t know about the drawing mode. This did the trick. Could see lots of microscopic tracks that needed to be cleaned up.


for the original DRC-question you can also use the “pcbnew–>Tools–>Cleanup Tracks and Vias” utility. It’s good to play a little with that tool to get a feeling for the effects.
