Does anyone know how to draw a NSBezierPath that is exactly 10mm long?
I have no problem drawing a line that is 10 points long but that is not millimeters. I basically need to draw some lines that are to scale - i.e. I want to draw a 10mm so that when it is printed it is 10mm long.

To convert points to mm you multiply by 2.834646, so in theory you would just create a path of 28.34646 points in length and it *should* print correctly, provided you are not transforming the view in any way and the printer driver is printing at 100%.
