did you have a look at the [code in this post](http://forums.sketchup.com/t/how-can-i-get-the-outer-loop-of-multiple-faces/18325/2)?

it’s best to let users model units to work automatically…

```ruby
akDefaults = ['1.6mm'.to_l] 

```

also, I’d consider adding a material to the pcb at the same time…
