Attribute Assistant Intersecting Feature Method -> Attribute Rule?

Hello,

I'm trying to convert from using Attribute Assistant to Attribute Rules and I'm struggling with one of my old rules built with the INTERSECTING_FEATURE method. Here's the problem:

I'm mapping parking blocks and I need to pick up the street name of the longest intersecting street segment (S 19th St in the simple illustration below)

The ArcMap/AA method worked beautifully and seemed to pick up the longest edge most of the time. However with the new Attribute Rule that I set up (using Pro 3.0), it seems to pick up the other streets that it intersects with, even if it's just one vertex (COURT D or FAWCETT AVE above). When I loop through all the features it seems random, so I can't use the FIRST function.

I think I'm still not understanding the fundamentals about how the Intersects function works. Does anyone have any suggestions on how to filter out the street segment with the longest intersecting edge?

Thank for you thoughts and suggestions!

Here's my code:

//Cycle through all intersecting streets and return street name
var streetLayer = FeatureSetByName($datastore,"baseStreetCenterline", ["ST_NAME"]);
var searchDistance = 0;
var streetIntersect = Intersects(streetLayer, $feature);
var cnt = Count(streetIntersect);

var name = Null
if (cnt > 0) {
    for (var street in streetIntersect) {
        name = street.ST_NAME;
        }
    }
else {
    // pass no features found within search distance, name remains null
}
return name;

Intersects() finds all intersecting features. In the next step, you have to get the actual Intersection() and find the longest one.

// find intersecting streets var streetLayer = FeaturesetByName($datastore, "baseStreetCenterline", ["ST_NAME"], true) var streetIntersect = Intersects(streetLayer, $feature); // find the street with the longest intersection var name = null var max_length = -1 for (var street in streetIntersect) { // get the intersection var segment = Intersection($feature, street) // get the intersection's length // if the line and polygon only touch at one vertex, segment will be null var segment_length = IIF(segment == null, 0, Length(segment)) // compare to max_length, set name if(segment_length > max_length) { max_length = segment_length name = street.ST_NAME } } return name

You're a genius Johannes!! That works perfectly, thank you!!

Has anyone been able to figure out how to set this up referencing boundary layers in another database? Attribute Assistant could do it in the map, but since Attribute Rules are in the database, it can only look at other layers in the same database. I'm not adding the parcels, neighborhoods, zip codes, addresses, municipalities, and county boundary to each database where we edit to make something work in Pro that worked in ArcGIS Desktop...
