Deleting incorrect traces after schematic update

[marchinghome]

After I’ve made changes to the schematic is there a way to delete the existing bad/wrong traces on the PCB layout?

When I import the new netlist and update the PCB, all of the existing traces remain - and some are connecting parts that should no longer be connected. Is there a simple way to delete all of these old traces that are now incorrect?

pcbnew -> Edit -> Cleanup Tracks and Vias.

Also this can be helpful, when you read netlist you can delete tracks shorting multiple nets
