Been a while since I used Autocad and am getting back into it. If your line is going somewhere else than where you expect it to go, maybe you are giving the wrong direction. Remember that to get a line to go to the right you are sending it at angle 0 degrees. To go up is 90 degrees. and 180 degrees is to the left. 270 degrees is down. Perhaps this is where your difficulty is starting at.

I graduated from a drafting course 10 years ago, so this is by my very weak memory, and I have not used it since, (the drafting unfortunately), but should be right. Not sure I have used my memory either for that matter! (grin)

Hope this has helped!
