Thank you all, but I know how to do the actual measurements.
I'm specifically looking for a flat, large, printed piece of paper, that allowed one to simply place the shotgun on the paper, at specific points and get all of the appropriate measurements by simply reading them off of the chart. There were lines delineating the actual Drop at Heel, etc. with individual lines notated as 1.5" / 1.75" / 2.0", etc. No rulers necessary. It looked to be a much simpler and quicker approach to getting all of the measurements.
