This is why the exploder is cool. Summary: Pattern With Rotation
Thanks Doug and Rui. I had played with this a little until my job got in the way. I had the same Idea with spline. I was able to make a group and in the pattern the planes look correct, but I cannot get the protrusion to follow along. It gets, I believe, too closely tied to the first point. And subsequent pattern extrusions fail. I attached my file for reference, still not sure why it won't work.
Doug you would still be struggling for days from a forum post on this, if you remembered to go look for an answer.
