Tool for finding unused faces?

[Dario D.]

Is there some tool in Hammer for finding coplanar faces? (faces that are lying inside or against another face, and therefor completely hidden and useless)

I have lots of faces within func_details that need to become nodraw, but finding all of them in this map could take all afternoon. Is there a shortcut to finding and selecting them all?

I don't know of one, I usually build geometry with some working texture then do the real texturing later and replace the working texture with no draw when I'm finished.

I have heard of no such tool and therefore i always make all of my brushes covered in the nodraw texture to start off with and then I just texture the visible bits. That works everytime.
