Hey ho,
I try to select/ not select the first AND last point of a line.
I managed to select first and last independently from each other, but when I want both…
nothing seems to work.
can someone explain to me, where my misconception is?
What kind of line? A mesh line or a curve line?
For a mesh line check the number of connected vertices. If it’s greater than 1, then it’s not an endpoint. Mesh lines don’t have a defined start or end, since the vertices don’t have to be in order.
For a curve, there’s a the endpoint selection node, it can select points from the start or end. The selection can be inverted with a Boolean Math node.
It wasn’t about finding an Endpoint.
I am already able to find Start and End points but not to combine this.
I assumed that min max would help, but i doesn’t
I also combines greater than and less than in the second step, to no effect.
Can’t say I understand the logic of your selection 
…but nevertheless, the simple way to combine Selection (which is just 0 and 1 values) is to use Boolean Math with “OR” operation.

Thank you, that did the job!
