So I think I've come to what is at least MY personal conclusion about this. You can use other programs to do full models and all that and with enough time and effort, you could probably have Fusion 360 do the same thing. However, for my use of this, I'm just going to get the profiles of a plane, laser cut them, then somehow piece them together until I get a plane. I mean...scratch building is a wonderful skill and doing things this way would add a little bit of fun into the building process. If you have just a few pieces but no way to put them together, it'll be much more challenging and fun to try and glue them together into a final shape. In my personal experience, things usually turn out alright if it's done this way. Long story short, I'm going to be using Fusion 360 to convert a 3d model into basic 2d sketches which I'll cut out then put together somehow. It's a foam airplane, what's the worst that could happen?
