Hi, I am creating a ArcGIS Desktop Python add-in that has a tool to cut polylines of a layer by drawing lines across, just like the cut polygon tools in editor mode. I am able to cut polylines with my tool and save it but the problem is; I am unable to select properly any polylines of that layer after my cut operation. My add-in code is given below. onLine method of CutTool is called when the mouse button is double-clicked to finish drawing the line on the map. class CutTool(object):     """Implementation for PlugIn_addin.tool (Tool)"""     def __init__(self):         self.enabled = True         self.shape = "Line"     def cut_geometry(self, to_cut, sel_fid_query, cutter):         """         Cut a feature by a line, splitting it into its separate geometries.         :param to_cut: The feature to cut.         :param sel_fid_query: Selected Query FID to cut.         :param cutter: The polylines to cut the feature by.         :return: The feature with the split geometry added to it.         """         arcpy.AddField_management(to_cut, "SOURCE_OID", "LONG")         geometries = None         polyline = None         edit = arcpy.da.Editor(os.path.dirname(to_cut))         # Edit session is started without an undo/redo stack for versioned data (for second argument, use False for unversioned data)         edit.startEditing(False, True)         # Start an edit operation         edit.startOperation()         insert_cursor = arcpy.da.InsertCursor(to_cut, ["SHAPE@", "SOURCE_OID"])         with arcpy.da.UpdateCursor(to_cut, ["SHAPE@", "OID@", "FID"], sel_fid_query) as polylines:             for polyline in polylines:                 if cutter.disjoint(polyline[0]) == False:                     geometries = polyline[0].cut(cutter)                     polylines.deleteRow()                 if geometries:                     for geometry in geometries:                         insert_cursor.insertRow([geometry, polyline[1]])         # Stop the edit operation.         edit.stopOperation()         # Stop the edit session and save the changes         edit.stopEditing(True)     def onLine(self, line_geometry):         mxd = arcpy.mapping.MapDocument("CURRENT")         df = mxd.activeDataFrame         layers = arcpy.mapping.ListLayers(mxd)         to_cut = None         sel_list = None         query = None                 # Find the selected layer and selected polylines of that layer         for layer in layers:                 desc = arcpy.Describe(layer)                 if desc.shapeType == "Polyline" \                         and hasattr(desc, 'fidSet') and desc.fidSet:                     to_cut = layer                     sel_list = desc.fidSet.split(";")                     query = 'FID IN ('                     for sel_id in sel_list:                         if sel_id != sel_list[0]:                             query += ","                         query += sel_id                     query += ')'                     break         if to_cut:             self.cut_geometry(to_cut.dataSource, query, line_geometry)         else:             pythonaddins.MessageBox("There is no selection.", "Cut Polyline Features", 0)                     pass ...
