I'm working for a GAS utility, I have Pipe Exposures (Points) and they are snapped to either a Main(line) or a Service (Line).  Using ArcPy I've tried to do a intersect with a try/except block, if try the service and if not try the main. Along the way set a variable to let me know which layer it's on. It's part of editing, as each gets different values. My code snippet below: try:     arcpy.Intersect_analysis('Pipexposure #;Service #', PipeExposure_Intersect, "ONLY_FID", "", "INPUT")     theLayer = "the Service" except:     arcpy.Intersect_analysis('PipeExposure #;DistributionMain #', PipeExposure_Intersect, "ONLY_FID", "", "INPUT")      theLayer = "the Main" arcpy.AddMessage('The Pipe Exposure is on '+ theLayer) No matter what I put a point on, it returns on the Main. I'm stumped and wondering if there is a better way to determine what layer is intersected. I do have an "Exists/than Delete" for my in_memory/PipeExposure_Intersect FeatureClass. that runs before I check. ... View more

I've create relationship classes but they want to see specific fields as the attribute index. .i.e. See yellow highlighted text. In my case I have points and have about 10 Relationship class tables. They all seem to work properly, but for each attribute table the field value it's showing under "Attributes from xxx" is coming from different fields.  How do I specify which field to use? I'm using a script to create these and the tables are  related all on the same field names. Is there a way to set the fields it uses for this?  I'm using python to create these, here is my code: tables = arcpy.ListTables() for i in tables:     if (i != 'Structure'):         print(i)          tab = i          relClass = i+"_rc"          forLabel = "Attributes from Table"          backLabel = "Attributes from " + i          foreignKey = "equipment_number"          primaryKey = "PARENT_EQUIPMENT_NUMBER"          arcpy.CreateRelationshipClass_management(tab,                                                                                   "StructurePts",                                                                                   relClass,                                                                                   "SIMPLE",                                                                                   forLabel,                                                                                   backLabel,                                                                                   "NONE",                                                                                    "ONE_TO_MANY",                                                                                   "NONE",                                                                                   primaryKey,                                                                                   foreignKey) ...

Hi, using arcpy I'm trying to calculate a field that's using a domain. I'm actually calculating 2 fields, one after the other. The first one works but the second one doesn't set it's new value. No error messages. If I'm not using python and just field calculate it "USER" puts "User-Derived" in the field. However my script just doesn't. ArcMap 10.6 with a File GeoDataBase Featureclass   Any ideas? try: # Execute CalculateField # this one works well. arcpy.CalculateField_management(ug, "MEASUREDLENGTH", dist, "PYTHON_9.3") arcpy.AddMessage("Calc'd MEASUREDLENGTH") # this one is supposed to end up with "User-Derived" but doesn't do anything arcpy.CalculateField_management(ug, "LENGTHSOURCE", "USER", "PYTHON_9.3") arcpy.AddMessage("Calc'd LENGTHSOURCE") Domain Key/Value: FM Field Measurement MS Mapping System USER User-Derived WM Windmil WO Work Order Package ...
