So I have been using the transform orientation of a particular face to perform transformations on an object. I want to use an array to duplicate the object and rotate it around (like propeller or fan blades). I am using an empty object as the offset for the array.
The problem is that I want the empty’s axes to align perfectly with the transform orientation of the face I was using to create the fan blade, so that when I rotate the empty to offset the array, the fan blades will align perfectly to the transform orientation of the face.
Right now all I can do is assign the empty as the object offset for the array, rotate the empty along the z-axis to “fan” out the blades, then manually adjust the the rotation of the empty around the y-/x-axis so the blades approximately are aligned with the fan face.
Can anyone tell me how I can simply align the axes of the empty to the transform orientation of the face I was using to create the blade I want to duplicate? Then I can just rotate the empty around it’s local z-axis to “fan” out the blades and they will be perfectly aligned with the fan face and the rest of the fan.
Thank you.
