You can edit any subcircuit, this doesn't depend on being tru-hole or not.=
=20
But whether you want to edit a footprint or want to edit parameters for a=
=20
script rather, depends on the footprint being a static file footprint or a
parametric (script) footprint.
Parametric footprints are scripts that generate the footprint data for=20
you, reading your parameters. You can edit the script itself (with a text=
=20
editor), or you can edit the parameters. Note: a parametric footprint is=20
really just a script that takes parameters and generates subcircuit data=20
for you. At the end pcb-rnd is dealing with subcircuit data only.
Once an instance (with a specific script and parameters) is generated,=20
your footprint is just subcircuit data. When you place it on the board,=20
the generated subcircuit is copied onto your board, a copy will appear in=
=20
your board file. You cna also save this in a file, getting a static file=20
footprint. But since that's already just data, you won't be able to edit=20
parameters on it.
Static file footprints are just subcircuit data once drawn (or generated=20
or hand written with a text editor) and saved as data in a file (or on=20
the web).
You can edit a subcircuit by using the GUI (pcb-rnd, there are at least 3=
=20
ways doing that) or by using a text editor. But remember: if you edit a=20
subcircuit, you edit the data - not the script that can generate it, not=20
the parameters that were using for generating it, but the output of the=20
process. So we typically don't do large edits on generated subcircuit=20
(e.g. parametric footprint output), we rather change the parameters or the=
=20
script and re-generate the subcircuit.

Don't worry, this is the right place to ask questions about pcb-rnd!
