I see that the intermediate layers are labeled L1, L2, etc.

For a 6 layer board, are the boards laid out as follows:

---component---
------L1-------
------L2-------
------L3-------
------L4-------
----copper-----

Or is it:

---component---
------L4-------
------L3-------
------L2-------
------L1-------
----copper-----

I would think it would be the former, but the order in the pull down 
menu suggests it is the latter. I want to be certain I know which 
plane to use as my ground plane.

Regards,

a+
