The simplest thing is to open the footprint file in the layout editor= and use the cursor and or the measure function to determine distances.

Good work on the file system.

I usually create a project directory = and put my usual/frequently used footprints in the packages or fp subdirect= ory, depending on the naming convention in the template being used.

The main thing is to ensure tha= t the=C2=A0 screw terminals you are using are spaced 0.2 inches apart. The = hole and annulus sizes can be easily modified in the layout editor, but pin= spacing is harder to modify in an existing footprint. You should always ch= eck that footprints you source from elsewhere have sane annuli and hole siz= es before sending off the board for fabrication.
You are right, any three pin symbol can map to a t= hree pin footprint, provided that the pin labels on the footprint are sane.= Sometimes imported symbols like the one you mention need to have the pin n= ame changed to "1" instead of "_1_" etc... To make the = netlist behave when imported into the layout editor.

Hi E= rich Heinzie,
I think so. If I may reformulate it to show that I underst= and:
The PICAXE14M.sym file contains a statement: footprint unknown. Whe= n I enter the symbol on the schematic I add the footprint attribute DIP14. = The PCB program then picks it up from tha Symbol file and find the DIP14 fo= otprint from /home/gaf/pcb-elements.

Then the files:
/home/gaf/gs= chem-sym
(ls /home/gaf/gschem-sym
PICAXE-14M.sym)

/home/gaf/pc= b-elements
(ls /home/gaf/pcb-elements
DIP14.fp)

/home/.gEDA/ga= frc
(cat /home/.gEDA/gafrc
(component-library-search "/home/gaf/= gschem-sym")

should do the job?

But then, when I have fi= lled in the files, how do I make the PICAXE14M.sym appear correctly in the = add->component list?:

> Basic devices
> Connectors (gene= ric)
.
.
.

I want to understand the stuff completely and re= ally appreciate your help.

In general, gschem is unaware of footprint file names, or the det= ails of any other attributes you attach to a symbol from a symbol library
The usual procedure, after addi= ng your symbol to the schematic from a library, is to add an "attribut= e" to the symbol, in this case a "footprint" attribute, equa= l to "DIP14"

T= he schematic file will end up with an ectra attribute within the picaxe ins= tance, along the libes of

The PCB layout editor, when you proceed to lay out uour design, i= s the software that has an understanding of footprint attributes, and will = search its library paths for a DIP18=C2=A0

Does that=C2=A0help?

The above link will download the raw symbol file as a .sym for use in the =

=
The DIP14 footprint required in the pcb layout editor will be a .fp file an=

http://www.gedasymbols.org/footprints/m4lib/DIP14.fp?dl

You can place the resp=

It looks like the package is a 14-pin D=
