I would like to use modifiers to mirror and rotate an object. Or simply, mirror on a point, not a plane.
Left on the image is the simple mirror modifier using the x-axis. I want to have the situation on the right, where the object is mirrored and rotated.
Red points correspond to each other. It would be easier than copying and rotating the object, because I want to model some kind of matching, point-wise symmetric chain links.
