Hi Michael,
I was just kindof chiming in to clarify what my original request was about for the others reading... I think you had it covered though, and I didnt have anything further regarding this..

But you just made a great "point" (Pun)

The adding point "On the curve" didnt change the structure of the curve at all, whereas, adding point to the (Whatever you call the dashed line that is planar between the control points) does change the shape..

So the new question is, could the add point command have a numerical value to set? Like "add 5 or 10 points?" and then of course to reverse it would be the other part.. Would there be a workflow to be able to remove points without changeing the curve structure???
