Currently, setting INTF_OUT_LAYER to PART_LAYER creates sub-layers for each part's linestyles. This allows for easy parsing of geometry in AutoCAD once exported. It will currently not auto-layer any phantom tangency lines, or datumcurves that are not the default linestyle. Adding this functionality would allow for much easier automation of 2D CNC file creation, and general output to 2D CAD.
