Currently trying to add a distance field in my shp file that will state the distance from 1 polyline to its closest neighbor polyline in the same shp file and after running the neighbourfinder as seen below

(for candidate only)

There were matched and also unmatched data. There were also addition fields seen below

which stated the closest distance for the matched data however when I exported this data to a writer it did not include these additional fields.

I'm unsure if this is the correct methodology to obtain the results I desire.
