The faces are all oriented correctly. I deleted the face and re-drew it with the same results.

Didier,
Thanks for the reply. There is no hidden geometry. It happens in a few locations in this larger scale site model...

Hi,

I'm having some trouble with this tool not covering the selected face completely. It works on most but there are a handful of faces on this triangulated surface that clump my grass proxy together. I am pre-selecting the face and using the "selected faces" option.
Any ideas?
