Filter Line by Z Value

[Dynamo_Ann]

Hello,

Hoping there is an easy solution for this, I tried a few methods, but cant seem to work it out.

I have CurvesFilterByHeight (Crumple), however the GetItemAtIndex is not always reliable at getting the curves at Z=50.

Is there a better way at getting the curves at 50 instead of by index incase that index is another height.

Thanks in advance!
