algorithmic modeling for Rhino

invert cullNth (Isolate Nth!)

Hello,

 

what is a nice way to filter a list?

 

I only want to KEEP! every Nth division point of a curve.

 

And I would like to keep it dynamic, so a cull Pattern would be very akward.

 

I tried to cull every Nth and then to subtract this List from the original one,

but I failed using the Math-Subtract-Icon.

 

Any easy solutions?

 

Best.
