Hatch Fill

 From:  scott (SSHWARTS)

Does anyone have a script (or start of a script) that would hatch fill a closed curve with lines? (bonus points for a cross hatch option).
What I need it for is that when I engrave bricks (yes, bricks) on my laser cutter, I actually have to use cut vs engrave so to fill the item in (vs just an outline) I have to cut little lines to give the effect.

Thanks,
Scott
