Thanks Kyatric, I could not find what I actually intend to do but with trial and error I discover Pin to Object and that works perfect. I can now drag and drop my line to any point and then move left or right with the wheel of my mouse. That gives me the exact angle and with another horizontal line I can pin point the exact position of the ball. Thanks for all the other info, still try to figure out how to download and use it. My brain is now in top gear and I only think of games to develop.
