If I understand your question correctly, my answer is that the ruler is serves as a straightedge. I use a bubble level on the frame to get it level, then use the ruler and level to get the neck flat if I'm working on it. The ruler is a Pittsburgh 48" adjustable t-square that I cut into lengths appropriate for bass and for guitar.
