Removing first and last point from a list

I’ve divided a surface into segments and I would like to extract certain points from that division. I can get the wanted lines of points using List Item component but I can’t figure out how to remove the first and last point from those lines.
How would I go by doing this?

sorry did it backwards, it’s like this:

(edit) oh, and:

Thanks for the quick reply!
It works on a single surface, but I definitely should have mentioned that I’m trying to make it work on multiple surfaces at once so it’s quite not working with what I’m trying to do.


post a file that’s congruent with what you want :slight_smile:

should be the same though…

That is basically what I managed to do, but from there I would also want to remove the highest and lowest row on red points. So basically the outer ring of points.

So I am basically creating a glulam roof and brackets of it, based on the height of the thinner beams. I’m just trying to add bolts to the brackets that Ive already modelled.

So I’m trying to get rid of the red points.

cool - for a quickie:
provided all your surfaces are untrimmed and four-sided then turn them into a mesh with mesh surface component (use same U and V divisions as with your surfaces) then grab a ‘naked vertices’ component from kangaroo and you’ll get both naked and clothed points, then re-list them into rows to make your beams


use flip matrix for the points output and then use list item the same way to grab top/bottom

maybe that help you to find the points based on u v directions
