I'm trying to make a Python script tool which uses the Trace Geometric Network tool (10.3). My script works in the Python window, but as a script-tool, it runs and NOTHING HAPPENS. Messages state: Executing..., Start time..., Running script..., Completed script... Succeeded at... It acts like the tool executed with no errors, but there's no visible output.
The Trace Geometric Network tool refuses to work inside a Python script tool the way it does in the Python window. I tried playing with the parameters, data types in of parameter settings, and deleting and remaking the tool several times. I even tried using other geometric networks with the tool. Finally, I made a bare-bones script with only the trace tool to troubleshoot, and NOTHING. I get the same action as above.
Here's my bare-bones script:
geoNetwork = arcpy.GetParameterAsText(0) inflags = arcpy.GetParameterAsText(1) barriers = arcpy.GetParameterAsText(2) arcpy.TraceGeometricNetwork_management(geoNetwork, "Trace", inflags, "TRACE_DOWNSTREAM", barriers)
Here's a screen shot of how I'm setting my parameters in the tool properties:
How can I to get this to work as a Python script tool?
Here's the actual code. As this tool executes, I can see it looping over the flags and selecting them one by one. No output group layer files are added to the map and no apparent traces are made. Again, these functions work as intended if pasted in the python window, but misbehave as python-script tools.
inflags = arcpy.GetParameterAsText(0) geoNetwork = arcpy.GetParameterAsText(1) barriers = arcpy.GetParameterAsText(2) outPath = arcpy.GetParameterAsText(3) outName = arcpy.GetParameterAsText(4) def makeFullPath(path, name): return path + "\\" + name def TraceCapture(inflags, geoNetwork, barriers, outPath, outName): mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd) flagList = list(arcpy.da.SearchCursor(inflags, 'UNITID')) trace = 1 segmentCapture =  for flag in range(1, len(flagList)+1): try: outputLayer = "Trace_" + str(trace) expression = '"OBJECTID" =' + str(trace) arcpy.SelectLayerByAttribute_management(inflags, "NEW_SELECTION", expression) arcpy.TraceGeometricNetwork_management(geoNetwork, outputLayer, inflags, "TRACE_DOWNSTREAM", barriers) arcpy.AddMessage("Trace_" + str(trace) + " complete") for lyr in arcpy.mapping.ListLayers(mxd, "", df): if lyr.name == "Sewers": pipesCursor = arcpy.da.SearchCursor(lyr, 'ASSETID') for i in pipesCursor: segmentCapture.append((flagList[trace - 1], i)) if lyr.name == outputLayer: arcpy.mapping.RemoveLayer(df, lyr) trace += 1 except RuntimeError: print "Flag " + str(trace) + " was invalid and skipped." trace += 1 continue arcpy.CreateTable_management(outPath, outName) outFile = makeFullPath(outPath, outName) arcpy.AddField_management(outFile, "manholeID", "TEXT", "", "", 10) arcpy.AddField_management(outFile, "pipeID", "TEXT", "", "", 10) with arcpy.da.InsertCursor(outFile, ["manholeID", "pipeID"]) as cursor: for row in segmentCapture: cursor.insertRow(row) TraceCapture(inflags, geoNetowrk, barriers, outPath, outName)
