I've searched for a solution to this but none of the other posts seem to provide the minor detail I'm missing.

My goal: I need to find the distance "as the crow flies" between street intersection points (point geometry features).

What I have: Street Intersection points feature set with a unique ID field populated for each point.

What I've done: [1a] NeighborFinder (Street Intersection points as both the Base & Candidate inputs) [1b] Vertex Creator using the Nearest neighbor output ( Mode= Add Point ; _closest_candidate_x & _closest_candidate_y)

[2] LineBuilder (inputs are the original Street Intersection points and the Vertex Creators output points) grouping on the unique ID field. However this process does not output any lines. What am I missing?

Step 1b should create a line between the point and its nearest neighbor (point a, adding point b creates a line)..

You should not need step 2.

On second thought, the closest neighbor for a point (if all points are fed as base and candidate) is the point itself. Therefor it will not create a line.

You will need to find the closest 2 points and use a list.

The connect the _list{1}._closest_candidate_x and _list{1}._closest_candidate_y in the VertexCreator.
