I have an ArcPy routine that will often fail if the processing extents are not set to "Default" but I can't find any documentation on how that is done. I've tried the obvious arcpy.env.extent = "DEFAULT" but it doesn't seem to change anything. Also tried arcpy.env.extent="MAXOF".
While on the topic of processing extents, will setting the processing extent on the menu of an arcpy routine also set the extents accessed under Geoprocessing>Environment>etc?
