# FDM todo
* fix thin wall support fill artifacts with complex nested polys
* post re-engage dwell (on first layer?)
* add support expand value to multi-part spacing (which defaults to 1mm)
* add lay-flat auto-rotation or from selected face
* add rafts, thin wall detection, manual supports
* add rafts, manual supports
* check for support / brim intersections on first layer
* solid fill every other line, two passes. minimize heat/sag. better fill between
* add dashed poly output on first connected brim (when offset === 0)
