Do you run into the issue of entering lot lines (connecting the dots) and wanting the lines to be true to their COGO measurements and in the same time snap to the points. This is an experiment of using an attribute rule to snap to the nearest vertex (within tolerance). The other ways of achieving the same result without the attribute rule are: Using the Traverse tool to set the start and end points, then enter a one line traverse. Digitizing the line between the 2 points and then using the attribute pane to enter the direction and distance. Using the Direction and Distance constrain as shown in the video and then use the Extend/Trim tool.     Please leave a comment with your thoughts. Here is the Arcade expression and the screenshot of the rule:   //name: Auto Snap to Line Ends //desc: Modify the newly created line feature to snap to the nearest vertex of the nearest line //The attribute rule searchs for the first line and finds the nearest vertex in that line //SETTINGS var tolerance = 0.1; //Set your desired tolerance var toleranceUnit = 'meter'; //Set to 'feet' or 'meter' or other var ParcelLinesFS = FeatureSetbyName($datastore,'Parcel_Lines',['*'], true); //Set 'Points' to the fully qualified table name //Variables var LineEndVertexGeometry = Geometry($feature).Paths[0][1]; //geometry of end vertex var EndX = LineEndVertexGeometry.x //the feature end vertex X var EndY = LineEndVertexGeometry.y //the feature end vertex Y var BufferedEndPoint = Buffer(LineEndVertexGeometry, tolerance, toleranceUnit); // buffer the $feature end vertex using the set tolerance to find lines var nearestLine = First(Intersects(ParcelLinesFS, BufferedEndPoint)); //find the nearest line that intersects with the buffered line var vertex = NearestVertex(nearestLine, LineEndVertexGeometry); // Get the nearest vertex of the nearest line. That's the target location. if ((Count(Geometry($feature).paths[0]) == 2) && (vertex != null)){ //if the line is a 2 point line (not a curve or polyline) AND the nearest vertex is not empty var x1 = TEXT(Geometry($feature).Paths[0][0].x); //start X coordinate of $feature var y1 = TEXT(Geometry($feature).Paths[0][0].y); //start Y coordinate of $feature var x2 = vertex.coordinate.x; //target X coordinate var y2 = vertex.coordinate.y; //target Y coordinate if ((x1 == X2) && (y1 == y2)) return; // safe guard for small lines not to try to snap on their own start point (which is where another line might end) var dist = sqrt(Pow((x2-EndX),2) + Pow((y2-EndY),2)); // the distance between the end vertext of $feature and the nearest vertext if (dist > tolerance) return; //must be smaller than set tolernace //if we got here all that is left is update the geoemtry of $feature :-) var SR = Geometry($feature).spatialReference; //spatial reference of the line var polylineJSON = { //create a JSON representation of the updated line "hasZ":true, "paths":[[[x1,y1],[x2,y2]]], "spatialReference":SR }; return Polyline(polylineJSON); //return the Polyline to update the SHP field }     ...
