Hi Edward,

Looks doable to me.

The Decision to be made is: exporter or plug-in ?

Anyone with a bit of coding skills can do, it's a matter of choosing a 
suitable HID template, a lot of free cycles and go for it.

As I see it, it would approximately take some 200+ hours to code and tweak.

And that is a lot of free cycles for me in the current situation I'm in.

I've tried to code dxf, openscad and even html5 exporters, which are all 
in an unfinished and sorry state because of my free cycles are getting 
more rare by the month (my employer thinks he can double the work done 
by hiring 5% more workforce, the silly git).

All this stuff is hidden in my pcb devel repo at Github.

Kind regards,

Bert Timmerman.
