I learned excel and photoshop on my own, without documentation, just figuring things out as needed. Asking a coworker "do you know how to refer to the value in another cell?" is not the same as reading documentation.

Even then, new CAD self-learners would almost certainly start with a newer, more intuitive CAD app to get their feet wet.
