This is a lecture that I highly recommend to those who are learning Rhino for the first time or learning on their own. I personally went to an academy before, but I forgot about it, so I started studying on my own again, and after watching YouTube videos and reading reviews, I made up my mind to buy the lecture and listen to it. It is so helpful and I am grateful that I am re-establishing my basics!!! Thank you. :) I will continue to buy and listen to other lectures!
