Hi! I get the value all the way down to 0.01mm grid size and snapping to 0.005mm. But I guess first you need to set alt snap all the way down to 0.005mm as well.  You can also try to set routing angle to "free angle" and this way you can route a track from other pad to other pad straight. Regards, Markus Virtanen HW / Electronics Designer

the schematic and symbol doesn\t support to set lower than 1, maybe you need to set the Snap as No
