Hi Barbara,

Thank you very much for the reply.

I do have "no library dependencies" NOT checked, and I do not see any flash
symbols being generated.

This is a board that is only a few years old, and I believe was created with
at the oldest 15.2.  If the flash geometries are not in the file, how does
it create the Gerbers?  And, I don't know what flash convert is...  Again,
this is an extracted library from a .brd file, so that's all I have to work
with.

Regards,

Austin
