No Mounting Holes

[yepher]

I was going to use Notecarrier%20AF(Standard%20Build).step to design a case for my notecarrier-af that I just got. But the step file does not have the holes for the board.

But this is what the step file looks like when I open it.

Is there an accurate step file somewhere that I can use for my case design?
