I just bought a plotter and have been making GCODE while I wait for it to be delivered. Playing around with gcodetools a bit and I was wondering if there is a way to have strokes not be drawn if they are behind a fill. For example, in my attachment I have 5 squares, if I export this to GCODE it still draws the lines behind the middle square.Is there a way to prevent this from happening? What about when using masking elements? Do I always need to flatten the shape all the way? (By Path->Difference)
