I'm attempting to add Winglets to a small drone propeller. One has been made fine, the problem is on a propeller one winglet must bet swept up, and the other down. I'm having a difficult time either rotating and mirroring, or mirroring then rotating etc. I unfortunately can't just re-create the 3D sketch on the other side because the spline curves won't match exactly.
New to the forum, any help greatly appreciated!
