3Ds Max How to Select Nth vertex on a Spline...?

Jonathan85

Hello
How would i do this? I hava spline object and i want to select every "N-th" vertex ("knot")... In my case it every second vertex/knot, but every 3rd, 4th, or simply - N-th would be good. Is there a way how to do it in max? Either directly or with the help of some (preferably free) script or plugin etc...?
I know max can do it defaultly via the ribbon toolbar with polygon objects, but i dont know how to do it on spline object...?
Thank you

The script above works this way:

- select a spline

- go to Spline subobjectlevel and select desired spline(one, two or more)

- go to vertex subobject level(to see the selected verts)

- press the [Select] button
