Connecting every point with each other with line in ArcMap

Question

I have a dataset of points and I would like to make lines connecting each point with all the other points of the dataset.

It is similar to Creating all possible line segments between all points using QGIS but I want to do it in ArcMap.

Is this possible?

Of course it's possible. What have you tried, and what problem did you encounter? — Vince, Oct 20 '20 at 11:28
About 200 points. So basically the question is if there is already such tool available in ArcMap. Otherwise I can spend more time to do it manually with ArcPy (I guess by using multiple times the POINTS TO LINE tool) — GeoF, Oct 20 '20 at 11:35

I dont know of such a tool.

You can use arcpy with itertools.combinations:

import arcpy
from itertools import combinations
pointfc = r'C:\GIS\ArcMap_default_folder\Default.gdb\samplepoints'
coordinates = [xy[0] for xy in arcpy.da.SearchCursor(pointfc,'SHAPE@XY')] #List all point coordinates
arcpy.CreateFeatureclass_management(out_path='in_memory', out_name='lines', geometry_type='POLYLINE', spatial_reference=pointfc)
icur = arcpy.da.InsertCursor(r'in_memory\lines','SHAPE@')
sr = arcpy.Describe(pointfc).spatialReference
for p1, p2 in combinations(coordinates, 2):
    newline = arcpy.Polyline(arcpy.Array([arcpy.Point(p1), arcpy.Point(p2)]), sr)
    icur.insertRow([newline])
del(icur)

Cool, learned something, thanks: itertools > combinations – KHibma Oct 20 '20 at 11:51

Always set a SpatialReference in the Polyline constructor, or the coordinates may have truncated precision. – Vince Oct 20 '20 at 11:55
