So i have been messing with inkscape and i followed eriks way of creating g codes for the my needle cutter with im done building it. my question of the day is what is the purpose of overlapping line's on an image, is it just to make the lines darker. i was doing MDK2 F-14. i was trying to conect nodes and some time i would drag the line and i found out that some time's there were like 10 line under that line so why do they do that is it to make it darker?
