Inset on Select Bit?

[keninar]

Afternoon All,

Been away for a spell - trying to get back up to speed.

Have a non-closed path that I would like to cut along with a .125 straight bit- but to preserve the desired dimension, the bit needs an offset (inset?) as one gets the option of dong a cut path. I don't seem to have the inset option when using Select bit to follow a line. Cut path not an option (non-closed and nothing off the board edge I think are the requirements.)

Am I missing something obvious? Do I have to have the bit follow the center of a line?
