I have made it through this point and find this very helpful. I have the most difficulty with orbiting the object with the Shift-click mouse wheel. There doesn't seem to be any reason to the movement or I am just not use to it. Jumps at the start and moving the mouse in a direction doesn't move it like I would expect. Is there a way to select a rotation point or some other instruction in a YouTube video that can help with that aspect?
by the way, thanks. This has been very helpful
