Personally, I suggest you go to class to study about 3000 to 5000. If you feel expensive or have a high degree of trust in yourself, you can also try to buy books, about 1 0,000. But if you encounter problems, it may delay a lot of time. Might as well go to class and learn to take notes. If you have the conditions, you can also buy books during class, so you can read books. If not, you can go there and ask if you want to know the progress of his teaching, preferably the kind that you can keep learning. It is estimated that you should achieve something in half a year, but you should be diligent and do it yourself. You'd better choose one of 3D MAYA. 3D is biased towards architecture. MAYA has better role handling. Personally, I prefer maya. I hope it will help you.
