I HATE AUTODESK. I TRIED TO EXTRUDE ONE THING AND THE WHOLE SOFTWARE CRASHED. THIS IS SO AGRAVATING AND IT ALMOST SEEMS LIKE IM DOING IT ON PURPOSE BUT IM NOT. I HAD NOT DONE THE INITIAL SAVE SO THEREFORE EVERYTHING I DID TODAY IS GONE. I COULD HAVE SWORN THAT I HAD SAVED AND I THOUGHT IT WAS AUTODSAVING BUT I WAS MISTAKEN. THIS IS REALLY TESTING MY PATEINCE.
