Solidworks: Even More Satisfaction!

In addition to the welding class, I took a CAD/drafting class at LBCC that taught how to use Solidworks. I 3D-printed myself a keyfob. There’s not much to say about Solidworks other than that I learned how to use the various tools within the program and just drew. The program itself is just a tool, […]

Satisfaction: I can weld! (MIG and stick, anyway)

Okay, more honestly, I’ve just started coding again after a month of chemistry. It was still fun! Check out my (slow) progress on […]
