So when I write this code df = arcpy.mapping.ListDataFrames(mxd,"Layers")[0] print df.extent   In return the numbers showed me   238135.744094489 3606562.79790026 494041.255905512 3787829.20209974 NaN NaN NaN NaN   What does NaN NaN NaN NaN   mean ?   Is it  laughing at me ??  No, I know !   what does it mean, BTW !   Thanks ...
