Sketch Tree Line

This command draws a tree line as you move the cursor. At the first prompt, you can type O for Options and set the Interval Scaler which controls the spacing of the bubbles. Also at the first prompt, you can type P for Polyline and then select an existing polyline to convert into a tree line. At the end, there is an option to flip the side for the bubbles in case they came out on the opposite side.

The resulting tree line after you pick point to end
