Not a very good tutorial and it does not tell me how to move the
positioning diamond.

Well, that does not make much sense as the crosshair moves.

Whatever! Names are optional. I could make up a make up a name, but
you really get hung up on a name don't you!
I don't care that you don't care! Fine, I won't use a name at all
then.

Everybody's "basic understanding" differs. I'm with Stefan here, but
you have different perceptions. That's how it goes with gEDA. With a
flexible toolkit, there are going to be many approaches. This is a
good thing.

Well, I was using the valueless passive symbols quite a bit
yesterday. But I guess I'm "virtually nobody".

"Getting Started with PCB" has a list of terms. I have a copy
online
here:
[25]http://www.delorie.com/pcb/docs/gs/gs.html#Terminology
footprint
A footprint is the pattern on a circuit board to which your parts
are attached. This includes all copper, silk, solder mask, and
paste
information. In other EDA programs, this may be referred to as a
?land pattern?. ?Footprint? sometimes is used to refer to a
footprint file. ?Footprint? refers to the pattern; ?element?
refers
to the instance. For example, your layout might have four
elements
that use one footprint.

Not always a "low entry barrier" is a real benefit.
In the technical world, there are good reasons for the use of
uncommon
screws, so that fools can not open dangerous devices.
In the Internet world: Nearly all people now have access to
information,
this is great. But so many seems to think that they have to add
silly
content everywhere -- newsgroups, Internet platforms, blogs,
facebook,
all filled with silly stupid stuff, the same questions and comments
again and again, more than one typo in each line, written without
any
grammar from people without real names. I really try to get not in
close
contact with all that dirt, but sometimes you have a problem which
wikipedia can not explain, you have to do a google search and gets
all
that dirt before useful content.
Often I have seen people new to a project, they were exited and
started
a tutorial about that... Some weeks later they discovered how much
work
it is, they stop working on it, but often the pages with headlines
but
no contents remain for years in the net.
But my conclusion is not, that a fully open wiki is a bad idea for
gEDA
-- I am not sure.

File->Save
But first it is important to recognize that there is a difference
between editing a symbol, and editing a schematic with a symbal
instance
and instance attributes.
Until now we were talking about editing a symbol instance in a
schematic. To make a new symbol version, you must open the symbol
file
itself. You can do that by selcting the symbol in a schematic and
do
Hierachy->Down Symbol (Shift-H s)
You will discover, that the symbol still has no value attibute. You
can
add it in the symbol file. The value attribute must be promoted
when
the symbol is instantiated. There are (not so?) complex rules which
attibutes get promoted, and which not. I think, a visible,
unattached
attribute, called _value_ will be promoted.
N.B., this is a dark side of gschem in my oppinion. Which attibutes
get
promoted should be defined in the symbols, independently of
visibility
or any strange configuration settings.
After adding the attibute, "value=?" with proper placement and
alignment, you can do File->Save_As to save the new symbol in your
own
symbol collection. Edit->Symbol_Translate will probably not be
required, if you just do a minor modification to an existing symbol.
Then you go back to your schematic, Hierachy->Up (Shift-H u) and
delete
the old symbol instance, and replace it with an instance of your
own.
How to reload the available symbols from a running gschem? I don't
know.
Usually I restart gschem, to reread the available symbols. You'll
first
need to add the location of your own symbol collection to the search
path in .gafrc or something.

And that is a real problem. gschem should really be able to to this
automatically when saving symbols.

I was wondering if someone could tell me how to move the positioning
diamond
in PCB or how to move the the foot print itself so it is centered
over the
diamond. Usually, I have to take several hours to move everything
in the
*.fp file itself.

Kai-Martin gave you the link how you can make footprints from inside
of
PCB:

And I told you that you may use other tools for footprint creation.
I have no intention what your goal is, and for people without real
name
I do not care too much.
