    Do not use R format, only I J K format for arcs.
    While R will work most of the time, there will be times when it does not work and will try to do the 'wrong side' of the arc, usually an enormous arc that causes crashes and other chaos.

    Do not try to do arcs that are smaller than 1mm radius. Again, sometimes they will work, but often they will not.
    In our Fusion360 postprocessor arcs that are smaller than certain limits (absolute chord length and also related to tool radius) are always linearized.
