Hello,
I am trying to get the elevation using a NeighborFinder. I get this error:
IFMELine was given an index beyond its current range (see workspace in attached)
And I get 'nan' for the elevation. Any idea why?

NeighborFinder: Try to get elevation but get this error: IFMELine was given an index beyond its current range

@lau This does seem to be a defect in the NeighborFinder. When the point (Base) is past the end point of the line (candidate) then you'll see this error. We'll get this fixed.

You do not have any z value on neither the line or the point.
(no z value does not mean that the elevation is zero, it means there is no such value)
You could add elevation at the creator(s) or use a 3d forcer to add a z value.

I think the error has been caused by a defect of the NeighborFinder. Hope someone from Safe to clarify this.

+3I found a workaround but indeed, it seems there is a bug with the "Take z From Candidate" functionality of the NeighborFinder.
I use a densifier to densify the vertex of the candidates. Then I used a chopper (1 vertex) to get points. I recorded the z in an attribute and use merge attribute in the NeighborFinder. Not efficient but effective :)
