Object Orient Tool
Object orient tool for Maya
Allows you to restore the orientation of an object based on selected reference elements. This tool is useful when the original object has been transformed in the scene and the transformations have been frozen. For example, all geometry in the scene has been merged into a single object. After separating the large object into individual objects, the Orient Tool will help you restore the transformations of the original objects and move them to the center of the world coordinates. You can also return the restored object to its original location in the scene, but with the correct transformations.
