Thanks shonner: I've tryed this and it works, but how do you keep the all the points close enough together when you change direction of the line? Can can you stack the points on top of each other, or do you zoom way in to see the individual points? I'm able to drag all of them together and leave one point behind as I continue elongating the line, but this leaves a straight portion of the line containing the unused points that doesn't follow the direction of the line, especially the first couple changes of direction of the line. Thanks everyone for your help.
