this gets me basically what i want, the double wish bone minus the arrow heads, if i change LINE to Leader. It gets me one leader but it goes through all three points.
For the second question. I am not quite sure what you want. Are you picking in space, 3 arbitrary positions (points) and then want to draw 2 lines between the three points and at the first point and the second point, draw an arrowhead?
As a suggestion, before learning lisp, go through EVERY AutoCAD command and system variable and make sure you understand the prompt sequences. Without a very good grasp of how the commands function, LISP will only cause trouble and lost time.
