Say,
does anyone know how to get spice-sdb or the like to pass non-default port
types to ngspice for the xspice code models? Most of the standard code
models default to single ended sources eg. %v(1) where the %v() is
optional, but often you want a differential input. This means you double

It looks like you are almost to the next step, but probably the
biggest value of having good 3d representations is the ability to do

PCB does that (spatial data-structures) already for rendering layers, so
yes. With the 3D perspective view, I fall back to rendering the whole

I took that as known, but I don't disprove of using good commercial
software to do a job. I find Blender quite challenging to work with.

Hi Kai-Martin Knaak,
(get-selected-filename) is a Gschem Scheme procedure which
returns the current page filename as string. May be you can
try something like this:
(print-command (string-append "lp -d PDF -t "
(basename (get-selected-filename)))
The above works only if your Gschem filename
