Align to a center point

Pick a circular arc or edge to direct the axis of the Manipulator to the center of that object.

Pick		Aligned

It has to be kept in mind that although the Manipulator axis will be aligned with the picked object, its position remains the same as before. Also there is no link between the Manipulator and the picked element with which it has been aligned. From here the Manipulator’s position and orientation can freely be modified again.
