I started tinkering with building bows sometime late 2020 or early 2021. First design was one of Kenny's 58/60" forward handle bows. Awesome design, but not knowing what I was wanting I built a dozen or so, gave a few to friends, kept a couple and cut the rest up. Built a mild r/d that I never could get 2 to tune the same, not to mention I always felt rushed once I started building, and grew to dread my time in the shop. Took a break from building, cleaned and changed my shop layout a little, built a slight backset ASL, got one shooter out of 3 that I still have, then moved on to 3 or 4 different revisions of a 3 piece until I hit burnout from frustration last winter. Started tinkering with a very mild r/d form that would end up sitting on my bench for months now. I've been pondering coming up with something that doesn't really draw from any other bow I've seen recently, that being an r/d with an asymmetric riser and a more recurve shaped grip. Working from home now, I think I can finally start tinkering with putting this idea on paper, but I'm wondering if anyone using any sort of CAD program to help work out the kinks and dial in optimum performance through automated testing before the first bit of sawdust flies?
