Help! I've been struggling with Eagle for a couple of hours now. I am
trying to create a part for the 18f452. I've created the part, named it,
used a DIP40 layout, but now I'm trying to get the symbol in there. What
I'd like to do is copy an existing symbol from the library (a 16f877)
and just modify it. But I can't seem to copy it. I can insert the f877
symbol, but then if I modify it, I'm pretty sure it will modify it for
the 16f877 part entry as well. I have tried opening up the symbol editor
with the f877 part, copying it, then opening the 18f452 part and trying
to paste it, but it says the paste buffer is empty. Does anyone know
what I can do to accomplish this? I am using Eagle 4.09r2.

I know that by now I could have just started from scratch and created a
part, but I'm not so clear on all the layers and the like. I am also
really confused about naming nets and then having them magically connect
together in the layout. I wish I could associate a the Vcc and Vss nets
with the +V and ground symbols so when I plop those in, the correct
things are put to power or ground. I haven't tried to actually layout a
board yet as I can't complete any of my schematics without creating
parts...which I'm not doing so well at. Maybe I'm missing something that
will become self evident at that time. I don't really know. At the
moment all I wish to do is finish my 18f452 so I can start using it!

Thanks for any help!
