Kind of an oddball question, but it fits here, I think?

My main interest is that I want to be able to use CAD/3D modeling to design firearm frames and things of that nature, and then also be able to take those 3D printed prototypes eventually to metal (maybe).

Does anyone know if SDI would be a good option to learn those skills? Or are there other courses/schools I could look into to get better at the 3D modeling side of things? I’ve heard from a few sources that say SDI is a sham for learning real gun smithing, but I really am more interested in learning online the CAD side of things, and then maybe learning the actual manufacturing part later.

A bit of background, I’ve been 3D designing for a while(1-2 years), I started modeling my woodworking projects and now moved to designing 3D printed stuff. I’m currently active duty, so the school would be free, it would just take up more of my time. TIA!

It's a literal scam, almost everything they try to teach you can easily just be found on YouTube for example(and probably in better detail as well) and for a very technical hands-on craft like gunsmithing 'Gun Jesus' said it best it's impossible to learn in person skills online, if you want to learn real actual gunsmithing rather it be basic repairs,gun design/manufacturing, marketing, etc what I would recommend is either look for a local certified gunsmithing school/ class or try to get an apprenticeship with a local certified gunsmith
