Maybe it's a little late, as there has already been a summary posted...
Anyway, here's an idea that worked with my part:
I created the curve as sketch (straight lines), including the points.
I added a csys on the first point, one axis normal to the sketching plane, one normal to the sketched line.
Then I point-patterned the csys activating the option "Follow curve direction"
Finally an axis through the x-axis of the first csys, reference pattern it
Have a good one.
