When creating part files, if I save as a part file and save exterior faces only has anybody else had some of the exterior faces removed.
Not sure to follow what you are asking here?
I'm trying to save my assembly as a part file with no inside. By using exterior faces part file this sometimes works but on other occasions missing faces happen in the part file.
Can you post your part here so we can take a look?
Are you saying that when you save a part, you are saving only the exterior faces and then when you open it again some of the exterior faces have disappeared?
Yes, normally I save all components.
