The hardest part about doing this assignment was learning how to use rhino on my laptop instead of the computers at school. Getting items to line up where I wanted them to was extremely difficult. I played with the buttons at the bottom of the screen that said "edge", "midpoint", etc but I still had problems. At first I had problems with filleting and champfering but after a LONG while I figured out the trick. I also could not get wire cute at all but I asked a friend and she helped me out. Regardless of the problems I encountered I still enjoyed learning the program and I believe I get along with this program a lot better than sketch up :-).
