I have followed this video from Lynda http://www.lynda.com/articles/dekes-techniques-drawing-a-perfect-spiral-in-illustrator to try and make a perfect spiral for a logo I am working on. I've done each step but when it comes to the part where I actually bring the bottom lines to join with top ones Illustrator keeps jumping so the lines wont meet. I've looked at the incremental settings incase that was the cause but that is set at the very lowest (0.01 pixels). I've tried turning on and off the "snap to point" option but that doesn't make any difference.
This is as close as I can get and if I move it again it just jumps to the other side....
