When I need to learn a new graphics package for work, I play around with it as much as I can, and then look up how-to's on YouTube. Within 3 days of getting a new 3D package, I was able to do brief, usable animation. As time went on, I filled in knowledge gaps as necessary, project by project.
Sitting in a classroom for a semester and learning the software from top to bottom, and features that I may never use, is an enormous waste of time.
Semesters are not needed for basic software.
Commonly only 1week is even offered from pro software tutoring companies for such learning. I just took one 2months ago covering basic Solidworks in 4 days. Still nothing like being hands on guided, incidentally, even in that example. Rather than hunting and pecking. Just like typing. Much better taking the class than “I know where the letter keys are!” You are stil slow compared to me who learned seriously and can type fast.
That is my point. It does not take long to learn these mere tools. They are NOT the principles, which often take longer to go over. Different issue.
