As I only found a cut function that allows to cut a polyline with another polyline, my initial guess was to just creat a dummy line at the position of the point feature that helps me splitting the line. However that seems quite complicated for a seemingly easy task. Has anybody another approach or idea how i could solve that problem? Perhaps even without using Attribute Rules?&nbsp;</P><P>Thanks in advance</P><P>Stefan!</P> Wed, 09 Nov 2022 14:47:03 GMT https://community.esri.com/t5/attribute-rules-questions/arcade-splitting-intersecting-line-with-created/m-p/1229951#M648 StefanAngerer 2022-11-09T14:47:03Z https://community.esri.com/t5/attribute-rules-questions/arcade-splitting-intersecting-line-with-created/m-p/1229979#M649 <P>Check out this rule -&nbsp;<A href="https://github.com/Esri/arcade-expressions/blob/master/attribute_rule_calculation/SplitIntersectingLine.md" target="_blank">https://github.com/Esri/arcade-expressions/blob/master/attribute_rule_calculation/SplitIntersectingLine.md</A></P><P>&nbsp;</P><P>&nbsp;</P> Wed, 09 Nov 2022 15:10:08 GMT https://community.esri.com/t5/attribute-rules-questions/arcade-splitting-intersecting-line-with-created/m-p/1229979#M649 MikeMillerGIS 2022-11-09T15:10:08Z https://community.esri.com/t5/attribute-rules-questions/arcade-splitting-intersecting-line-with-created/m-p/1229981#M650 <P>An older version of the rule did use cut, if you are interested in the logic, it pasted it below.</P><P>&nbsp;</P><LI-CODE lang="python">function cut_line_at_point_cutter(line_feature, point_geometry) { var search = Extent(Buffer(point_geometry, .1, "meter")); var geo = Geometry(line_feature); var segment = Clip(geo, search)["paths"][0]; // Rotate logic - https://stackoverflow.com/questions/45701615/how-can-i-rotate-a-line-segment-around-its-center-by-90-degrees // Start and end points of the line var x1 = segment[0]['x'] var y1 = segment[0]['y'] var x2 = segment[-1]['x'] var y2 = segment[-1]['y'] //find the center var cx = (x1 + x2) / 2; var cy = (y1 + y2) / 2; //move the line to center on the origin x1 -= cx; y1 -= cy; x2 -= cx; y2 -= cy; //rotate both points var xtemp = x1; var ytemp = y1; x1 = -ytemp; y1 = xtemp; xtemp = x2; ytemp = y2; x2 = -ytemp; y2 = xtemp; //move the center point back to where it was x1 += cx; y1 += cy; x2 += cx; y2 += cy; var cutter = Polyline({ "paths": [ [ [x1, y1], [x2, y2] ] ], "spatialReference": { "wkid": geo.spatialReference.wkid } }); var new_lines = Cut(line_feature, cutter); var line_a = Dictionary(Text(new_lines[0])) var line_b = Dictionary(Text(new_lines[1])) line_a['paths'] = remove_vertex(line_a['paths']) line_b['paths'] = remove_vertex(line_b['paths']) return [Polyline(line_a), Polyline(line_b)] }</LI-CODE> Wed, 09 Nov 2022 15:12:02 GMT https://community.esri.com/t5/attribute-rules-questions/arcade-splitting-intersecting-line-with-created/m-p/1229981#M650 MikeMillerGIS 2022-11-09T15:12:02Z
