I have been teaching myself Fusion 360, free if you are using it for a hobby. I program 3 axis mills at work, but have no 3D software at home. I have been using Autocad for about 12 years and Vectric Vcarve 2d and Aspire 3D modeling software for about 8 years or so. My first project with Fusion is Laurel Hill Barge #2, a colonial period rice/utility flat of chine Log construction. I have the chine log, keelsons and headers complete and now need to add frames, planking and strakes.
