[GIS] Creating point at specific distance along line in ArcMap

arcgis-desktopperformance

I have a road (line) system and would like to place culverts (point) at specific distance along the road. The Construct Points tool creates multiple points spaced out at the users specified interval, but I would like to create a single point at a specified distance. What's the fastest way to do this?

I doubt that this will end up being "the easiest" way to do it, but you can certainly achieve this using Python:

points = []
arcpy.MakeFeatureLayer_management("line_file", "selected_lines")       # change "line_file"
with arcpy.da.SearchCursor("selected_lines", ("SHAPE@")) as cursor:
    for row in cursor:
        points.append(row[0].positionAlongLine(10))                    # 10 is the number of units
arcpy.CopyFeatures_management(points, 'in_memory\points')              # output layer
  1. Select your line, or lines.
  2. Copy and paste the above script into the ArcMap Python window. Change the input layer, number of units, and output layer.
