Sorry for the noob question, but obviously I am new to all of this.
I have used Rhino3d, and am thinking about purchasing it when I get my first cnc mill (I am a teacher, so it is only $195.. not $995, lol)
I guess I always figured it all worked through 'magic', but I keep reading that people use 1 software for CAD work, and another for CAM work, then a third to send it to the machine.
So what is the difference between CAD and CAM? Is CAM determining tool paths and stuff?
I thought I could just design the part, then have another program send it to the machine, but I guess I am missing a step.
