Attach existing line endpoints to existing points

ShawnKraft1 — Tue, 11 Apr 2023 15:31:49 GMT

I have stormwater laterals(lines) and inlets(points). I need to connect the laterals endpoints to the inlets. Snap doesn't seem to work as it would move the points to the lines.

Backup your data, this will change the geometries!

Use the Field Calculator on the Shape field, switch to Arcade, use this script (change the first line to your point fc name)

// load your points, define the snap radius var inlets = FeaturesetByName($datastore, "TestPoints") var snap_radius = 5 // get the current geometry and create a copy var geom = Geometry($feature) var new_geom = Dictionary(Text(geom)) // we want to edit the first and last vertex -> indices 0 and -1 var vertex_indices = [0, -1] // loop over those indices for(var v in vertex_indices) { var i = vertex_indices[v] // get the vertex var p = geom.paths[i][i] // create a buffer around the vertex var p_buffer = Buffer(p, snap_Radius) // get the first point that is within the buffer var p_snap = First(Intersects(p_buffer, inlets)) // no point found? -> skip if(p_snap == null) { continue } // change the vertex coordinates to those of the snap point new_geom.paths[i][i][0] = Geometry(p_snap).X new_geom.paths[i][i][1] = Geometry(p_snap).Y // new_geom.paths[i][i][3] = Geometry(p_snap).Z } return Polyline(new_geom)
