Another way is to use the dip direction (azimuth of creates dip) of the plane and the dip value (angle between the plane and the horizontal), a method typically employed in geological applications. Similar method could be applied to arrow sources. I also suggest that the origin can be defined by snapping to pre-existing points in the project.
