It would be great if there were an easy way to update the geometry of existing features in real time / after an edit is made.

It would be the equivalent of a DB trigger, but using logic similar to the Python field calculator script below:

#Updates the vertices of existing features
def new_shape(geom):
    spatial_reference = geom.spatialReference
    geom = geom.densify("ANGLE", 10000, 0.174533)
    parts = arcpy.Array()
    for i in range(geom.partCount):
        part = geom.getPart(i)
        points = arcpy.Array()
        for j in range(part.count):
            point = part.getObject(j)
            point.M = geom.measureOnLine(point)
            points.append(point)
        parts.append(points)
    return arcpy.Polyline(parts, spatial_reference)


Currently, there doesn't seem to be an easy way to do that in ArcGIS Pro, without customizing via a .NET add-in.

And unfortunately, it's not possible in the DB either, since the SDE.ST_GEOMETRY (Oracle) functions are too limited.

@Scott_Harris 

Thanks! I'd been reading the docs for Arcade, and came across this line:

"Geometry is immutable, meaning it is not possible to change the geometry after it is created."
https://developers.arcgis.com/arcade/guide/types/#geometry

So I figured Attribute Rules (which I think use Arcade) wouldn't be an option. But I must have misunderstood.

No problem @Bud !

I'll set the status of the Idea to closed. If you end up trying Attribute Rules, a good place for questions is https://community.esri.com/t5/attribute-rules/ct-p/attribute-rules
