Change symbol rotation - Water utility network

[Letíciad_Agosto_Miguel_Fonseca]

Hello Everyone!

I am trying to rotate some symbols in my Utility Network PRO project (using ESRI template: water distribution network editor) but I can't change the ones that already have numbers.

Example: I want to change the rotation from 119 to 29, calculating on field calculator it runs, but it brings me back the same number (119). (Image attached)

Any help will be very usefull 😃

Regards,

Will have to debug the rule and build out the scenarios. Are the mains split at that location, what are the lines digitized direction. Is this the sample data?

[MikeMillerGIS]

Is the rotation set to Geographic or Arithmetic? That looks like the issue actually

[Letíciad_Agosto_Miguel_Fonseca]

Hi Michael, yes this is my sample data.

The mains are not Split (as you can see from selection) and we set to Arithmetic rotation because of the attribute rule. It seems to be following the line direction (Distribution main), but we needed it to be set to the service line.

Can you verify this is the rule you are using?

https://github.com/MikeMillerGIS/arcade-expressions/blob/master/attribute_rule_calculation/RotateFeatureByIntersectedLine.md

Based on the logic, you should be around this section of the code:

else if (Count(angles) == 2) {

// If the feature is midpan of the first line, return the angle of the second line

if (angles[0]['type'] == 'mid')

return angles[1]['angle'];

// If the feature is midpan of the second line, return the angle of the first line

else if (angles[1]['type'] == 'mid')

return angles[0]['angle'];

Can you create a pop up on taps and use this rule. Then you can add to the return statements to see what part is being users?

Such as

else if (Count(angles) == 2) {

// If the feature is midpan of the first line, return the angle of the second line

if (angles[0]['type'] == 'mid')

return “Count 2, angle 1 is mid” + angles[1]['angle'];

// If the feature is midpan of the second line, return the angle of the first line

else if (angles[1]['type'] == 'mid')

return Count 2, angle 2 is mid” + angles[0]['angle'];

Hi Michael, 

It worked using the rule with multiple lines. I set everything to null using the calculate field and changed the symbology layer.

But when I insert new features, it is returning 0 and I have to calculate null values to trigger the rule. I saw there is an issue with Arcade returning 0 instead of null :BUG-000119064: Calculating a value to null using Arcade returns 0.. 

This is how the code looks like now:

// This calculation attribute rule intersects a line layer and based on the number of
// intersected features, calculates the angle for the point
// Set to true if the rotation setting is set to geographic in the layer properties
var geographic_rotation = false;
// Set the counter clockwise spin angle used for the symbol in the symbology options
var symbol_flip_angle = 0
// Return if a value is already set, to recalculate an angle, the field must be set to null
if (IsEmpty($feature.symbolrotation) == false) {
    return $feature.symbolrotation;
}
else if ($feature.symbolrotation == 0) {
    return null;
}
// Create a feature set to the line layer
var lineClass = FeatureSetByName($datastore, "L515Water_Line", ["objectid"], true);
// Find the intersecting lines
var lines = Intersects(lineClass, $feature);
//If no lines intersect, return the original value
if (Count(lines) == 0) {
    return $feature.symbolrotation;
}
var diff_tol = 5;
// Variable to store all found angles
var angles = [];
// Store the features geometry
var feature_geometry = Geometry($feature);
// Loop over all intersecting lines and find their angles
var angle_type;
var angle_value;
for (var line in lines) {
    // Buffer and create an extenf of the point by a small amount to extract the segment
    var clip_area = Extent(Buffer($feature, .01, "meter"));
    // Clip the line by the extend and get the first line segment
    var segment = Clip(line, clip_area)["paths"][0];
    // The features location is on the start of the line, get the angle from the feature to the end vertex
    if (Equals(segment[0], feature_geometry)) {
        angle_type = 'from'
        angle_value = Round(Angle(feature_geometry, segment[-1]), 0)
    }
    // The features location is on the end of the line, create a new segment from the feature to the start vertex
    else if (Equals(segment[-1], feature_geometry)) {
        angle_type = 'to'
        angle_value = Round(Angle(feature_geometry, segment[0]), 0)
    }
    // The features location is midspan of the segment, use the angle of the segment
    else {
        angle_type = 'mid'
        angle_value = Round(Angle(segment[0], segment[-1]), 0)
    }
    if (geographic_rotation == true) {
        // Convert Arithmetic to Geographic
        angle_value = (450 - angle_value) % 360;
    }
    // Add 180 to match 0 rotation in the TOC
    // Add user specified spin angle if their symbol is rotated
    angle_value = (angle_value + 180 + symbol_flip_angle) % 360;
    angles[Count(angles)] = {'angle': angle_value, 'type': angle_type};
}

// If only one angle, return that value
if (Count(angles) == 1) {
    // If the point is midspan, flip to match symbol as it if was on the end point
    if (angles[0]['type'] == 'mid')
    {
        return (angles[0]['angle'] + 180) % 360;
    }
    return angles[0]['angle'];
} else if (Count(angles) == 2) {
    // If the feature is midpan of the first line, return the angle of the second line
    if (angles[0]['type'] == 'mid')
        return angles[1]['angle'];
    // If the feature is midpan of the second line, return the angle of the first line
    else if (angles[1]['type'] == 'mid')
        return angles[0]['angle'];
    // If the feature is at the end point of both lines, return the angle of the first line
    else if (angles[0]['type'] == 'to' && angles[1]['type'] == 'to') {

} else if (Count(angles) == 3) {
    // Flatten the angles to ignore direction
    var flat_angle1 = angles[0]['angle'] % 180;
    var flat_angle2 = angles[1]['angle'] % 180;
    var flat_angle3 = angles[2]['angle'] % 180;
    // Create differences between angles
    var angle_dif_a = Abs(flat_angle1 - flat_angle2);
    var angle_dif_b = Abs(flat_angle1 - flat_angle3);
    var angle_dif_c = Abs(flat_angle2 - flat_angle3);
    // If difference between line 1 and 2 is below the tolerance, meaning the lines follow the ame plane, return the
