Exporting Attachments by location Loses _REL (relationship)

DanielRydl

I have been working on exporting attachments from a point feature class by location (County).  The export is renamed by the area (County), which contains the feature class, attachment table, and the relationship class, using this: 

<SPAN class="keyword token">import</SPAN> arcpy<SPAN class="punctuation token">,</SPAN> os<SPAN class="punctuation token">,</SPAN> datetime<SPAN class="punctuation token">,</SPAN> traceback<SPAN class="punctuation token">,</SPAN> sys

This yields everything I need but loses the relationship.  Any ideas how to rebuild this relationship or how to successfully export the data that carries the relationship class?

Thanks,

Daniel
