""""""""""Is there a script that will take points along an existing curve and then create a new curve from it? """"""""""

Ctrl+C then Ctrl+V!!!! Lol

But really, this part:

""""""""""I know I can select the points, copy them and then use the ConnectPoints script followed by Join but looking for something easier.""""""

That would then make a "poly Line"! This "PointsOnAdaptiveCurve" will do that...\

Did I miss something?

Also, selecting points from an existing curve are not "points on the curve", but weighted points. You want a curve from the weighted points?
