How to get all Vertices from a trimmed surface?

Hello,

i think this question ist the consequence of a lack of basic knowlegde ;), but it makes me a bit crazy, would be great to help me out.

I deconstructed a surface and would like to have all points / vertices as a list, but i don´t get the points at the boundaries…?

Thanks a lot for your help!

According to your screenshot, it’s obvious that you used Isotrim and after thatDeconstruct Brep, so if you use List Item with item index 0, you’d get the first one of the four vertices. That’s why you won’t be able to get the boundary vertices. If you use item index of 0~3, then you can get all of them, but as a whole, you actually get duplicated vertices across the surface.

Thank you for your answer.
May i ask how would you do it without getting duplicated vertices?
I thought using maybe a “dividing surface” component to get this points?

That would be a way to go.
