And like the theory stated before, when this control is animated around, the locator currently drifts all over the nurbs plane.

BUT, if I scale the nurbs plane down to 0, there’s no surface area left for the locator to drift and volla, we have a locator pinned to the center of these floating dynamic curves that I can parent constrain what ever I want to. (FYI, if you tried using a polygon plane, you’ll notice the locator doesn’t follow any more once the planes scale goes to 0)
