    I see that message when I have "bad geometry."

    Did you Join other surfaces to the Unfolded surface? That might be a problem.

    It's hard to tell what you have there, and that's a pretty complex surface to develop (unfold) into a flat pattern.

    Try projecting the curve onto the unfolded surface before you fold it.
