Adding segment to Bezier curve When I attempt to add a second segment to a Bezier curve, it creates it very small and folded back on itself, almost like a circle. I create it by selecting the end point of the first curve and then Ctrl + LMB. I've tried this is 2.77 and 2.78c and get the same results so it's obviously something I'm doing wrong. Trying to find the new end point is difficult and when I do hit on it and drag it away, it generally wanders off the flat plane. Thanks.
Maybe you want to use the Extrude operation.  Select the last control point on the curve and hit e.  You can then move your mouse around to choose where the new control point will go.
