These are settings for the hatch vector type that is arranged in a parallel pattern.
Alternating: If enabled, the vectors alternate in their exposure direction.
Reduce Jumps: If enabled, the vectors within the parallel pattern are reapportioned in the exposure sequence. This can avoid frequent positioning and setting down of the laser.
Filter Length: The minimum length of the hatches. Hatches that are smaller than the defined value are not exposed.
Hatch Distance: The distance between the hatches.
Hatch Offset: The distance between the innermost border and the outermost hatch.
