eetu 531 Posted May 16, 2015 Here's one idea, instead of the polyframe tangent I used the vector from first to second point of the polygon for the rotation axis. Works in this case, but it of course needs the mesh to be constructed in a consistent manner. rotate_with_p01_helped.hipnc Share this post Link to post Share on other sites
