BladeWall
If you have a model with holes (aka not watertight model) the slice will contain only an open path.
There are two major ways to deal with this.
1: close the path with a segment, and get a closed polygon which is possible to fill.
2: leave it there and print only the path as a BladeWall without fill.
The "Contour auto close threshold" tells the slicer which paths to close aka maximum allowed segment length to close an open path. The remaining paths are printed with the bladeWall settings.
Please note that some layer is fixed with the autoclose and the others left there as BladeWall.
The Pros:
1: Auto close is capable of fixing some model errors and holes in slice time. You can control it how.
2: Some slicers left out those parts resulting a faulty, unprintable Gcode.
3: It is possible to model single paths with free faces, and have CAD prepared infill, or just force the slicer to draw something, without introducing the errors from the slicing and offseting.
If you turn off autoclose (0), and model something from faces, it will sliced as it is, without modification.

Interesting how some slicers just drop the open contours entirely. This makes BladeWall a surprisingly helpful fallback instead of leaving gaps or errors in G-code.
