    GENIUS!

    I've seen that happen near arcs, but it didn't register to do that on
    boundaries.

    What might work for you is to assign mesh densities to the lines or arcs
    at your region of interest. This can be used to increase the local mesh
    density w/out having to create additional regions just for the purposes
    of grading the meshing.
