I've just bought it 5 hours ago, I can't still make a simple hangar. The software needs to be simplified when placing different polygones together. Rotation and so on is completely out of control. Perhaps the manual doesn't go far enough. At one stage its says" add the polygone" . How do you do that? I am going to have another go tomorrow, but surely shouldn't take that long to get a grasp of what appears a simple software.
