Hi, I'm trying to make some odd shape spiral along a path like this.
and I try to sweep along this path with this cross section.
and then it got a little twist alone the path which can be see clearly at the end like this.
the twist is so small that it can't be seen at the beginning. but it can be seen clearly at the end of the path.
so, how can I fix this?
Try e.g. "Direction vector" in path alignment and select the top plane.
