I use 0.01mm, but close enough.
@Yuusuf_Sallahuddin_Y 
I use .001mm myself. But I don’t do that for every line. When I do an engrave, I’ll add a 2nd outline around the first that’s 2pixels away and 2 pixels thick. That way I don’t get an engrave between the outside & inside bounding lines - the inside one still controls, but I get a crisp finish edge to the outside of the engrave.
@Jim_Hatch Yeah that’s a good idea placing a thin border around engraves. I occasionally do that for a crisp edge also, as otherwise it looks vaguely aliased on the curves.
