i accidently placed a pad in my pcb layout outside the pcb box. but now i cant remove it.
could you suggest a method to remove it? i use altium designer 2016.
You can set the grid coarse (like 100 mils/2.5mm), hit Ctrl-A to select everything, then drag it up so the errant pad is visible. Delete it, then Ctrl-A again and drag everything back.
