Do any of my fellow scratch builders know where I can get a cad program for home use, don't need anything fancy, just trying to make rib patterns, not designing my own planes. I have a lot of plans where al they give on the plans is the root rib and tip rib template, and leave you gessing for the rest. pay premium for the plans also. If anybody has a program or copy of one, willing to pay for it .thanks so much for the tutorial.</p>
