My invention is a process involving items moving between points on earth, where distances between points are highly relevant. For example, given points A and B, it is important to know that A and B are 5 miles (or kilometers) apart. My diagrams of such a circumstance have an A and a B in solid-edged, hollow circles; a solid line joining them; and a number 5 embedded in the line between them, breaking the line. In examining the Nolo book on patents, I am unable to find any direction on how to indicate these dimensions, although I suspect the PTO will find my embedded numbers wanting.

How should I do this?
