Empty or Null M geometry returns the warning message: "WARNING 000635: Skipping feature <values> because of NULL or EMPTY geometry" when using the Calculate Geometry Attributes on a selected field for setting the point M-values.

Additional Information

Workaround

If the desired M-values for every vertices in a field is available, use the below Python code:

import arcpy

# set workspace environment

arcpy.env.workspace = r"<the path to the geodatabase>"

# Feature class to update

fc = "BECSM"

# field name that contains values we want to assign to M

field_name = "Measures"

# Use Update cursor to update M-Values

with arcpy.da.UpdateCursor(fc, ["SHAPE@M", field_name]) as cursor:

 for row in cursor:

  # Get geometry and field value

  row[0] = row[1]

  # update the row with the new value

  cursor.updateRow(row)
