I've only seen this over on a build thread on RCU for the Goldberg Extra. I thought it was a great way to make new ribs. He said it takes a while on 3/16 balsa, but it does a good job. He used power point to make the template, then imported it to the Cricut. Don't know if Cad will work, as I haven't searched about the Cricut yet. Maybe some of the other free software would work, as BalsaDust mentioned for making plans. I've got a NIB Goldberg Extra that I will build one day, for a Dle 20 and will use the kit to make templates for future kits.
