As far as i know kicad snaps to the pad center by default so i am a bit confused as to why it would be necessary to edit tracks manually.
If it does not snap to the pad center for you then check the preferences -> general settings dialog of pcb_new.
Is it possible that you work without connectivity information? (Meaning without a schematic or some other way to define which pad should be connected with which other pad.)
Thanks Rene,
I checked my settings.
General Settings > Magnetic Tracks > When Creating Tracks
Today the tracks are snapping to the center points of the pads. I don’t know why the feature wasn’t working previously but now it seems active.
