Design parameters?

I sent these questions to support a while back, but not having heard back (and figuring that the answers might be of general interest) thought I should ask again here:

  1. Board edges - I assume that you route to the center (as opposed to the inside or outside edge) of the outline segments, right? What is the tolerance on the edge routing? What clearance do you require from the edge to a copper feature or drill?

  2. I see that you don’t want the bottom layers mirrored. If I want text on the bottom copper or silkscreen layer to be readable on the finished board, do you want that mirrored?

  3. For mounting holes, are you OK with drill size = pad size? (KiCad won’t let me make pad size < drill size.)

Thanks!
