I measured all my bikes, I measured myself with the Competitive Cycle site, (
https://www.competitivecyclist.com/S...ulatorBike.jsp) I did a mechanical drawing before I ordered my last Workswell (066) and I made sure of the range where I wanted my contact points .... I know what range I can handle with stack, reach, effective top tube, and how long a stem and what angle I might need to get the bars right given those measurements.
This time I also I took the side-elevation photos off the site, and sized them in photoshop to scale, and added parts cut out of photos of my existing bikes. That was unnecessary and very time consuming.
