Hmm, I still haven’t found a solution, I’ve tried following the tutorial as exact as possible.
I’ve tried doing the curve pattern in sideways and topview, I’ve selected the vertex to the far right and done the Shift+S thing. I’ve tried spinning every vertex, spinning them all the same time, just spinning a few ones.
It says I should be spinning while in top view but no matter what I do, the thing remains flat, if I move the view a little though, I see better results.
The closest result I managed to come up wih was by doing the pattern in sideway mode.
