I have downloaded and had kinkos print out the full size plan. On the very bottom of the plan there are measurements that I don't understand. For instance; at measurement 15 there are dimensions of 6 1/4 - 6 11/16 below it, what do these measurements represents. Also, there is a 1/4 measurement listed, again what is that for.
I assume the answer to these quetions will pertain to the measurements shown at the rib pattern placement.
Thanks,
