Cutting Diagonally

Hello =) I’m back… and probably with another stupid question. =P

I am trying to make a fender bass guitar and guitars like that have a little indent near the top left (bottom left in the picture) of the body of the guitar.

i am wondering how to cut along that line in the picture… is it possible? or will i have to remake the left side of the guitar to make it work?

Thanks,
Kam

i guess the most straight forward way would be to use the knife tool (‘K’)

1 - you cold use the retopo tool to la down a diagonal line
then i fneeded you modify your mesh following this line

2 - you could cut yor guitar with the knife script also
i need it to cut it traight down

3 - the knife tool should help you if working on your OS

hope it helps
