pulling points of a curve_exclude endpoints

  Dear all

maybe a basic question

but i am trying to move only a centre point of a curve - that is attracted by a point - but until now i only have all the points of a curve moving - how can i keep the endpoints on their place and move only other points on a curve?

thank you

If you only want the middle point in a list of 3 points, you can use list item.

In case you want to remove the first and last point in a list of points, you can use shift list 2 times (1 and -1 afterwards). At least that's how I usually do it. I've been wondering if there is a quicker way.

Here's another way using Cull Index

Embarrassingly clever.
