It occurs as a result of shelling but I don't know what I've done wrong to cause it.
Also, is this just a graphical error or is the model itself broken? It does not flag up as an issue.
Can upload model if necessary.
Thanks
i've seen stuff like this before, try a Control+Q it will force rebuild everything
It's a symptom of a corrupt face. Usually the result of a trim or knit or offset that is not playing nice with the kernel.
You should still be able to select the invisible faces. Chances are, you can't make them opaque.
Hi Joe,
Look at the way that you applied your radii before you shell. Fillets (on the side indent) are usually the cause of this as the sheller offsets them in, it can geometrically reconcile them.

I went back and cleaned up the fillets and the problem is fixed, thankyou!
Joe,
Run the Check tool to make sure that the part is actually OK. I habitually use the Stringent option, assuming that it does a more thorough check. If the part fails, roll back before the transparent face showed up and run Check again. Often the part was bad before the problem becomes apparent.
Sometimes these transparent faces show up on parts that are corrupt and sometimes the part checks out OK. It does seem to me that parts with transparent faces are more likely to have problems later, so I consider them to be a sign that the model is on the edge of going bad.

You can try Ed Eaton's workaround: split the body in two in order to isolate the problem area, shell both bodies, then combine the bodies. Also see his excellent SWW 2014 presentation Make It Shell.
