If I understood your problem correctly, you have 3 tables / feature classes: the parcels, the address points and a standalone table containing the pdf paths. If that is correct, then the code I posted is the way to do it. If you can get the pdf paths into the address points (join), it would be easier: var addresspoints = Intersects( $feature, FeatureSetByName($map,"Addresses (GIS)", ["FullAddress", "PdfPath"]) ); var cnt = Count(addresspoints); var counter = (cnt-(cnt - 1)) if(cnt == 0) { return "No addresses found for this parcel" } address_info = cnt + " Address(es):"; for (var address in addresspoints) { var pdf_path = "" if(!IsEmpty(address.PdfPath)) { pdf_path = "; PDF: " + address.PdfPath } var address_text = (counter++) + ". " + address.FullAddress + pdf_path address_info += TextFormatting.NewLine + address_text; } return address_info;    Find is for finding sub-strings in strings. It won't help you with feature sets. ... View more

Interesting problem... No tools that I know of for both cases. You'd have to author them yourself with Python. Case 1: First thing that came to mind (completely untested):   def parallel_length_between_lines(line, reference_line, distance=None, tolerance=None): """Returns a list of the lengths of the line segments that run parallel to reference_line. The retuned lengths are the lengths of the intersection of line and a buffer around reference_line. A more correct way would be to deconstruct the lines into segments (split at vertices) and then to compare the bearings of those segments. But that would be far more computationally intense and far more difficult to program (I think). line & reference_line: arcpy.Polyline distance: the distance between the lines (the size of the buffer), optional tolerance: relative tolerance by which distance is multiplied (used to fake small variations in the distance as "parallel"), optional """ # calculate distance if not distance: distance = line.distanceTo(reference_line) if not tolerance: tolerance = 0.001 distance *= 1 + abs(tolerance) # create buffer buffer = reference_line.buffer(distance) # line and buffer do not intersect ? -> 0 if line.disjoint(buffer): return 0 # intersect line and buffer segment = line.intersect(buffer, 2) # return segment length # if line is "wavy" compared to reference_line (goes in and out of the buffer), segment will be multipart. Here, I return a list of the singlepart segment lengths, but you could also return the sum or the biggest part segment_lengths = [arcpy.Polyline(segment[p]).length for p in range(segment.partCount)] return segment_lengths   You would then have to apply this function to each line feature in your red feature class, comparing them to the nearest (?) line feature in the purple feature class.   Case 2: Sounds like a **bleep**-ton of math. Maybe arcpy.edit.Generalize could be a start? ... View more

Glad to help! Yeah, attribute rules (and Arcade in other instances, like popups, field calculation, advanced symbology and labels) can be pretty powerful, and they're still adding stuff to it. But you have to learn the language, it certainly helps if you have experience in other programming/script languages. You kinda jumped in at the deep end, here. There's a reason the blog is titled "Advanced Attribute Rules" 🙂   In case you haven't found it yet: The Arcace Guide and the Function Reference are great resources. ... View more

There is no function that does that. I don't think this is possible at all. Attribute rules work on the database level, and the database exists completely independent from any ArcGIS Project. ... View more

Please check that the variable field contains the actual field name and not an alias. # from your code above: liste = ["speed100m"] # each element of liste has to be an actual field name, not an alias! ... View more

Ah, now I get it... can confirm that changing the symbology WORKS when running the script outside of ArcGIS (e.g. executing it in IDLE) running the script in ArcGIS in the python window (either by copy/pasting or by importing the script) changing the symbology DOES NOT WORK when running the script as script tool ...

Updated the code in my comment above: Now it also finds relationship classes in feature datasets, and it returns a list of dicts instead of the old describe objects, so it's easier to read the output.   Not sure if this covers some of what you're looking for:   import os, pprint all_rs = listRelationshipClasses("path/to/your/database.sde") # see above pprint.pprint(all_rs[0]) # filter by name rs = [r for r in all_rs if r["name"] == "FilterName"] rs = [r for r in all_rs if "PartOfTheName" in rs["name"]] # filter by cardinality rs = [r for r in all_rs if r["cardinality"] == "OneToOne"] # filter by origin or destination table rs = [r for r in all_rs if "OriginTableName" in r["originClassNames"]] rs = [r for r in all_rs if "DestinationTableName" in r["destinationClassNames"]] rs = [r for r in all_rs if "OriginTableName" in r["originClassNames"] and "DestinationTableName" in r["destinationClassNames"]] # filter by dataset rs = [r for r in all_rs if os.path.basename(r["path"]) == "DatasetName"] # filter by flags rs = [r for r in all_rs if r["isComposite"]] rs = [r for r in all_rs if not r["isComposite"]] # other flags: isAttachmentRelationship, isAttributed, isReflexive, isVersioned, canVersion, changeTracked   ...

good, idea, upvoted. in the meantime, you can do this:     def listRelationshipClasses(database): """Returns a list of dictionaries describing the relationship classes inside the given database. Tested with SDE and FGDB database: str, path to the database """ desc = arcpy.da.Describe(database) parents = [desc] + [c for c in desc["children"] if c["dataElementType"] == "DEFeatureDataset"] rs = [] for p in parents: rs += [c for c in p["children"] if c["dataElementType"] == "DERelationshipClass"] return rs listRelationshipClasses("Path\to\your\database.gdb") listRelationshipClasses("Path\to\your\database.sde")       ...

Is this what you want? import os import arcpy aprx = arcpy.mp.ArcGISProject("path\to\your\project.aprx") active_map = aprx.listMaps("MapName")[0] lyr_directory = "..." for lyr in active_map.listLayers(): # etc aprx.save()   Also, you could rewrite your code like this: symbol_layers = { "Parcel_Buffer": "Parcel_Buffer_ArcGISPro.lyrx", "Parcel_Selection": "Selected_Parcel_ArcGISPro.lyrx", # ... } for lyr in active_map.listLayers(): try: sym = os.path.join(lyr_directory, symbol_layers[lyr.name]) arcpy.management.ApplySymbologyFromLayer(lyr, sym) except KeyError: print("No symbol file for layer {}".format(lyr.name)) ...
