Ask HN: CAD design for beginners

I am a developer who has recently become interested in fabrication and metal work. I think it's awesome to make stuff. I want to do more complicated things, f.ex. I want to build a special gate for my garden that folds in a specific way and requires me to build custom latches. I want to play with my ideas for the hinging and latching components in some sort of CAD software but the only two free pieces of CAD software I've been able to find (opencad and freecad) seem to be extremely complicated. Is there any sort of CAD software for beginners or a free online course that I could take?
