  • I’d start with some basic Linux networking and tools, if you don’t have them already.

    I don’t know if that’s the basics everyone knows these days, but… learn how TCP,UDP,ICMP,TLS relate, what a netmask is, what is ARP and MAC addresses. Fire up Wireshark and look around what is happening on your network. Learn some basic commands like ip -br -a and ss (or the older netstat) so you know how to figure out which program is listening where. Learn how to manually resolve a DNS name (dig or host). How tunnel a TCP connection or a webbrowser through ssh (port forwarding, SOCKS proxy). Learn enough of the HTTP protocol so you can manually enter a valid GET request over a simple TCP connection to port 80 with netcat or nc. Or use httpie or curl for the same purpose. You can’t host a lot with that knowledge, but it helps to figure out why things are not working.






  • Blender user here. I think you got it right, and FreeCAD is probably your best bet. Maybe give it a second chance.

    OpenSCAD is in a different category, it’s more like a coding tool or software library. There are other options if you’re into that, e.g. build123d.

    I can’t use FreeCAD myself, but then I don’t have a mechanical engineering background, so I was also learning the basic CAD workflow when I tried it. At work my colleagues (who occasionally 3D print some part) seem happy with it, and keep telling me I should use a proper CAD to design parts.

    Personally I’m happy with Blender, using it for my hobby 3D print designs. Most have some playful/artistic touch in addition to being functional, and Blender shines at that. But you totally can do a parametric design in Blender natively, it just won’t be a CAD workflow with the constraint solver you expect. The CAD plugins I have tried felt experimental. The native tools are very solid, and Blender is very polished and mature. But it is targeting expert users (including teams, since you asked about that). Learning Blender is an investment, it took me a long time. If you are still curious, look for a video demo/tutorial of someone designing a 3D part in Blender. Don’t just open it and expect to be able to do stuff, you will not figure out on your own which tools/modifiers you should use.

    (And since you didn’t say what kind of CAD, also check out KiCad if you are doing PCBs!)
