I might be having a thick moment here Al but, are they not designed to be a standard? So they can be copied
I've seen the wall charts in loads of places, maybe not all the symbols, but most of them. They must be readily available. How can you copyright something like that?
The AWS ones seam to be freely available, The AWS maybe thinks they should be standard to use.....
Also on Autocad 2010 theres a complete palate available for use, how does that work, if you plot a drawing using BS symbols are you in breach of copyright?
