You can make it 3D in autocad. I'm not super familiar with plain autocad 3D, but I know you can only really draw on a 2D plane. So what autocad does to get around this is with the axis. You can rotate the x,y,z axis to whatever plane you want to draw on. So you are still only drawing in 2D at any given point, but you put the drawing together in 3D. It's a little confusing at first if I remember from playing around with it. It's like the matrix, "there is no spoon. You are rotating yourself around the drawing rather than rotating the drawing" haha
Sorry I couldn't be much help. Finding a you tube video or two would probably help you out more than someone trying to explain it. It's kind of hard to explain without seeing it. Try to find a video with actually someone talking to explain it rather than just a video with music in the back ground. I hate tutorials like that. I would try to draw something much simpler first to get the initial hang of it before you try your rover, so you don't get frustrated.
