I added the via export support to the specctra_export.
defined: "stock" via:
a via defined outside a netclass in the arbitrary via list found
in the global design rule window.
For stock vias which are defined with drills of zero, these are exported as
such, with drills of zeros. I have not tested the ramifications of those
vias being used in freerouter and then being back imported. I think
some minor work
is needed here, and I think we have to agree what it means if a stock
via's drill is
zero in the back import. Is this now used instead of -1, and a zero
points to netclass Default's drill value or to the Netclass of the net
in which the "zero drill" via is used.
Some testing of the back import is needed in this regard, and maybe some
code tweaking, but probably not more than a line or two of code to fix
The ability to use Freerouter from Kicad in a vastly improved capacity
is within reach now.
I would say PCAD vendors and the like might actually be impacted
financially by Kicad & Freerouter in the near future, because this combo
of Kicad & Freerouter is no longer serving just the needs of the
This is my limited opinion of an industry that I do not know intimately...
And I am being very careful to include Freerouter in my guestimations,
because its routing capability drastically exceeds that in Kicad. It is
the combo that is becoming a powerhouse.
