script tool geoprocessing output NOT displayed to arcmap

DaveVerbyla — Sat, 19 Feb 2011 00:00:42 GMT

Is there a simpler workaround instead of arcpy.mapping modules to get the output from geoprocessing to display to arcmap when running a script tool? I am in arcmap with geoprocessing option checked on to add geoprocessing results to display...which it does in the Python window, but not using a script tool..
For example:
import arcpy
inFC = arcpy.GetParameterAsText(0)
arcpy.MakeFeatureLayer_management(inFC,"Test_Layer")
works, but does not return a "Test_Layer" to the data frame or table of contents.

running in the Python window, it works fine:
import arcpy
inFC = r'c:\test\Points.shp'
arcpy.MakeFeatureLayer_management(inFC,"Test_Layer")

are you running the tool from within arctoolbox?

Hi, the following will work for you.

Your script will be something like this:

import arcpy
inLayer = arcpy.GetParameterAsText(0)
outLayer = arcpy.GetParameterAsText(1)
arcpy.MakeFeatureLayer_management(inLayer,outLayer)
arcpy.SetParameterAsText(1,outLayer)

Now go through the wizard for adding the script to a toolbox. When you get to the Parameters page of the wizard you need to set your output layer as an Output using the Direction property (see the attached screengrab).
