1.Cover all surface: When checked, it forces the calculation loop to extend all the way to the maximum boundary limits, ensuring no edges are left short if the sizing steps do not divide evenly.
2.Distribute lines evenly: When activated, it dynamically resizes the gap between lines so every pass is spaced perfectly across the chosen area without leaving an uneven gap at the final edge.
3.Connect lines: Joins individual parallel lines together at their ends into a single, uninterrupted zig-zag path, preventing the robot from constantly lifting and resetting between rows. This setting is kept on by default.
4.Remove points that are not on the surface: This filters out calculation markers that miss the target geometry entirely. When active, lines that fall off the edges or pass through hollow cutouts/holes are deleted automatically rather than creating floating air-paths.
