This is probably the answer to my previous question.

The version of arcpy that I am using does not include GetNAClassNames

naClasses = arcpy.na.GetNAClassNames(serviceAreaLayer)

AttributeError: 'module' object has no attribute 'GetClassNames'

According to this help topic, GetNAClassNames is in ArcGIS 10.1. Why is it not in my version?

Thank you.

What version of ESRI products are you using? Some companies/organizations are behind because of testing and licensing requirements. –  mhoran_psprep Jul 2 '12 at 3:19

You're not on 10.1, plain and simple. It's only been out for a couple of weeks. –  Jason Scheirer Jul 2 '12 at 3:41
    
You are right. I checked my version and it is 10.0.2414. But now, there is no way for me to get that ClassNames of the service area layers?? I need to select the Polygons (layer) which is inside the Service Area layer. –  Janz Jul 2 '12 at 5:37

If your company is current on esri maintenance, 10.1 is available for download. The license manager will have to be updated, not a difficult task. The install is straight forward. Our only issue so far is ArcINFO Workstation 9.0 no longer talks with a 10.1 LM.

Caution: some companies/organizations restrict your ability to install or upgrade software. You may need to make a request to your IT help desk. –  mhoran_psprep Jul 2 '12 at 12:46
