I'm writing four tools to calculate X and Y coordinates in Northing/Easting then create a spatial ID based off of those coordinates. Each one will be stormpoint, stormline, sewerpoint, sewerline. So far, everything works exactly as planned except the part where CalculateGeometryAttributes_management deletes any layer that it doesn't work on. So if I have 5 stormwater point feature classes and input two it will delete the other three entirely. And just as a sanity check, I made sure that no other part of this code deletes entire feature classes when the tool runs. It produces this error since it can no longer find any data in the tables:
class StormPointAttribution(object):
def __init__(self):
self.label = "Stormwater Point Attribution"
self.description = "Calculates geo-spatial coordinates and spatial/facility IDs where applicable"
self.category = "Attribution"
self.canRunInBackground = True
def getParameterInfo(self):
input_storm_points = arcpy.Parameter(
displayName="Input Storm Point Features",
name="input_storm_points",
datatype="GPFeatureLayer",
parameterType="Required",

multiValue=True,
)
input_storm_points.filter.list = ["Point"]
params = [input_storm_points, ]
return params
def execute(self, parameters, messages):
# Define input parameters as a list
input_layers = parameters[0].valueAsText.split(";")
