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?

Answer 1

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)
