I have a polygon which I would like to build some curves from, but I can't really figure out a good way to do it.

Example:
I have a polygon with 45 points.
I'd like to procedurally convert point 0-14, 15-29, 30-44 into three nurbs curves.

Which is the best way to achieve that? And as fast as possible since I intend on constructing at least a couple of thousands of curves.

Add SOP
check Delete Geometry But Keep The Points
in Polygons Tab choose By Group
choose Groups of N points from the Add menu
type 15 in N field

this will create one curve from each 15 points

you have many different options if you want something else
you can append Convert SOP to make the curves NURBS or Bezier

Perfect, just what I needed!

I was on the trail. I was almost finished writing a Python script setting it all up with “By Pattern” but this is way better. Thanks!
