I'm in the process of putting together my first cnc machine and was wondering what cad software to get based off what I intend to build. I'm putting together a 4 axis cnc mill and was wondering which versions of Turbocad would work. I want to get a full 3d version, but would prefer to get a affordable copy, maybe version 15 or 16. I'm open to other cad programs, just need it to be affordable (~100$). Your experienced advice is appreciated.
