Yep. Inputting the values through the Active Template pane is sensible if you need new features to have an attribute, eg because you need it in an Attribute Rule that triggers on insert. If you don't need that functionality, the Attribute pane is the way to go. ... View more

Oh right. this calculation is for cartesian coordinate systems, as per your question. I have only worked with projected coordinate systems until now, so I'm not really sure how this will play out in a geographical coordinate system. The error might be negligible over small distances, but for greater distances, it will probably become apparent. Maybe you can get away with converting the points into a locally applicable projected coordinate system, do the calculation, and then project the resulting points into the geographic system. ...

PS: This problem has two solutions, depending on which diagonal the two point describe. If you change line 26 to take the arctan of 1/aspect, you get the second solution. Left: solution 1 -> atan(aspect), Right: solution 2 -> atan(1/aspect)   ... View more

Hey Helen, this will probably need a bit of Python.   Just to be clear: What type of "merge" are you talking about? Let's say we have two overlapping polygons in 2 layers:   Is your desired output the result of the Merge geoprocessing tool? This will combine multiple tables, each row of each table will be copied without editing. (Selection to show that they still overlap)   Or do you want the result of the geoprocessing tool Union? This works similar to Merge, but it creates the intersections as extra polygons. (Selection to show that the original polygons have been edited)   Or do you want the result of the editing tool Merge? This takes 2 geometries and turns them into one.   Or do you want something else? ... View more

Your braces in lines 11 & 12 are wrong, you have your id field outside of the attributes. Push(recalc.features, {attributes: {memberName: member, id: f.OBJECTID}})   ... View more

Getting the same behaviour for point features that are somewhere in between start- or endpoint For that, you replace the rule on the point fc with this: function split_polyline_into_segments(polyline_geometry) { // takes the polyline_geometry and splits it into segments (Polylines that have only 2 vertices) // returns an array of those segments var sr = polyline_geometry.spatialReference var vertices = polyline_geometry.paths[0] var segments = [] for(var s=0; s<Count(vertices)-1; s++) { var p0 = vertices[s] var p1 = vertices[s+1] Push(segments, Polyline({"paths": [[ [p0.x, p0.y, p0.z, p0.m], [p1.x, p1.y, p1.z, p1.m] ]], "spatialReference": sr})) } return segments } function project_orthogonally(point_geometry, line_geometry) { // returns a projection of the point_geometry onto the line_geometry // only start and end point of the line_geometry are considered! // the projection is done in 2D, the returned point_geometry has the same Z and M values as the input. // https://de.wikipedia.org/wiki/Orthogonalprojektion // https://en.wikibooks.org/wiki/Linear_Algebra/Orthogonal_Projection_Onto_a_Line if(line_geometry == null) { return point_geometry } var p = point_geometry var r0 = line_geometry.paths[0][0] var r1 = line_geometry.paths[0][-1] var ux = r1.x - r0.x var uy = r1.y - r0.y var lambda = ((p.x-r0.x)*ux + (p.y-r0.y)*uy) / (ux*ux + uy*uy) var new_p = Point({x: r0.x + lambda * ux, y: r0.y + lambda * uy, spatialReference: p.spatialReference}) // if new_p is on the line defined by r0 and r1 but not on the actual line_geometry, snap it to the closest end point if(Disjoint(new_p, line_geometry)) { new_p = IIF(Distance(r0, p) < Distance(r1, p), r0, r1) } // add z and m value new_p = Point({x: new_p.x, y: new_p.y, z: p.z, m: p.m, spatialReference: p.spatialReference}) return new_p } // get first line feature in a small radius var lines = FeaturesetByName($datastore, "TestLinesMZ", ["GlobalID"], true) var i_line = First(Intersects(lines, Buffer($feature, 1, "meters"))) if(i_line == null) { return } // split i_line into line segments (only 2 vertices) var segments = split_polyline_into_segments(Geometry(i_line)) // get the line segment closest to $feature function sort_by_distance_to_feature(s1, s2) { return Distance(s1, $feature) > Distance(s2, $feature) } var closest_segment = Sort(segments, sort_by_distance_to_feature)[0] // project point onto that segment var sp = project_orthogonally(Geometry($feature), closest_segment) // add vertex to the segment // the segment has 2 vertices // if point is on an end point, add vertext at end of line segment, else in the middle var new_path = [closest_segment.paths[0][0], closest_segment.paths[0][-1]] var i = When( Intersects(sp, new_path[0]), 0, Intersects(sp, new_path[1]), 2, 1) Insert(new_path, i, [sp.x, sp.y, sp.z, sp.m]) var new_segment = Polyline({paths: [new_path], spatialReference: closest_segment.spatialReference}) // replace the old line segment var i = IndexOf(segments, closest_segment) segments[i] = new_segment // create the new Polyline var new_line = Union(segments) return { result: {geometry: sp}, edit: [{ className: "TestLinesMZ", updates: [{ globalID: i_line.GlobalID, geometry: new_line }] }] }   Old line     Adding a point somewhere in the middle   Adding a point before the start point   ...

Instead of converting to Shapefile and referencing that, do it the other way around:   Load your CAD file, this will be inserted as a group layer.   Select on of the actual layers (eg Multipatch) to activate the CAD-Data ribbon   You can now georeference the CAD file like you would do with imagery. When you're done, you can export to the format of your choice. https://pro.arcgis.com/en/pro-app/3.0/help/data/cad/georeferencing-cad-data.htm ... View more

You can't use Arcade to reset the sequence, but you can do it without a sequence: // Calculation Attribute Rule // field: FacilityID // triggers: insert // get the feature that was created last var fs = Filter($featureset, "FacilityID IS NOT NULL") var last_f = First(OrderBy(fs, "OBJECTID DESC")) if(last_f == null) { return $feature.FaciltyID } // get its sequence value var old_seq = Number(Split(last_f.FacilityID, "_")[-1]) // get the new sequence value var new_seq = IIf(old_seq + 1 > 999999, 1, old_seq + 1) // construct and return the new FacilityID var s = Text(new_seq, "000000") var d = Text(Today(), "DDMMY") return `ABC_${d}_${s}` ...

calculate the 3D length of line features Length3D() does that.   add a vertex to the line exactly where the point feature is located in terms of x and y-coordinates, but with the same height as the line feature Not trivial, but doable. You'd have to project the point onto the line(in 2D, I have some code for that here), interpolate the height at that point, then insert a new vertex with the point feature's x/y coordinates and the calculated height.   I don't understand these two requests: the line feature - after adding the point feature- should have a "L"-Shape extending the line feature in a right angle to the point feature the point feature should become the new end/or start vertex of the line feature while still maintaining its height. The first request sounds like you want something like this (black: original line, blue: point feature, red: edited line, 2D): The second request sounds like you want to either split the line at the new vertex or to snap the point to a line end or something completely else.   Could you explain more clearly, maybe supply a sketch? ...
