Join an open source community that is welcoming to newcomers (e.g., BRL-CAD, Haiku OS, OSGeo, ..) and work on a little bit of code every day. It can be a simple feature, specific bug, or something new you want to achieve. Many open source groups are very welcoming to newcomers if you do the work and ask smart questions.

You could also try out free AutoCAD alternatives like libreCAD (2D), or brlCAD (2D&3D, I believe). Source: about 1 year ago
So, uh ... Learning curve. If you want anything and everything under the sun, go with BRL-CAD. It was designed for ballistics testing and simulation, but it can do pretty much anything. The learning curve for BRL-CAD is immense. Otherwise, I recommend OpenSCAD. Source: about 1 year ago
I use archicad - You can get a 30 day trial and after that you can still use the software in demo version which means everything is enabled but you cannot save the file (not great but its maybe worth it). https://graphisoft.com/us. Source: over 1 year ago
