I get this error when doing a render

Jerry Davis

When I do a preview, everything shows up fine.
When I do a render, I get this error.

I am using OSx version 2016.06.25 (git 7036a6d)

It must be something with a stl file I am importing.
Any idea what this could mean?

It usually is a bad STL.
You can check it with Netfabb Studio Basic
https://www.netfabb.com/products/netfabb-basic , put it thru their
online repair https://netfabb.azurewebsites.net/ , or post the STL here
and I'll take a look.
Sometimes they are repairable.
