DWG silently failed object export

The attached Rhino file is an object that, when I try to export it to DWG from R7, fails to export, but with no error message about missing or bad objects.

Hi Jim, we’ll take a look. Can you add your Rhino systeminfo?

Okay…though this is something I just noticed on this file that was exported in January, so…

I exploded and re-joined and redid the bottom ‘cap’ to get it to work.
