I´m always getting an Error with my Python-Code. Even though it is almost the same as on the ArcGIS Help Website.

The Error occurs in line 19:

Traceback (most recent call last):

File "C:_geodata\check.py", line 19, in


File "c:\program files (x86)\arcgis\desktop10.1\arcpy\arcpy\ddd.py", line 998, in RasterDomain

raise e RuntimeError: Object: Error in executing tool

Failed to execute (IterateRasterDomain).

My Code looks like this:

import arcpy
from arcpy import env


env.workspace = arcpy.GetParameterAsText(0)
rasterList = arcpy.ListRasters()

if rasterList:
    for raster in rasterList:
        geometry = "POLYGON"
        out_file = "domain_" + raster[:-4] + ".shp"
    print "Finished"
    print "No Data available"
  • Did you check the return value of arcpy.CheckOutExtension("3D") to make sure it is Available?. Commented Jul 20, 2012 at 14:15

Perhaps "rasterList" should be "raster" in:


From the documentation it looks like RasterDomain_3d takes only a raster rather than a list.

  • Thank you Cyrus. That really was the problem. Seems like I overlooked it
