Thanks for the reply! As I'm brand new to the PCB project, I'm afraid 
I'll be asking a few extra questions.
Did you mean auto-thermal and THERMAL flag, or do each via and pin have 
a VIA flag which indicates
whether it needs a thermal?

I guess the best thing would be for me to study the code. Which file and 
which function would I be best
to start reading?

Also, you mention a pin can be within a surface polygon but isolated 
from it. What is a surface polygon
(as apposed to an ordinary polygon)?

Thanks very much,

Jesse Gordon
