I am showing the bounding box in a drawing. The bounding box is of course auto created in the part.

On the drawing I would like to add dimensions to this bounding box. Does anyone know how to do this?
Ive tried just adding dimensions on the drawing and it wont allow this. It doesn't seem to even know the bounding box is there since Its not selecting it.

Keep in mind, if the method to do this is more involved than simply drawing a bounding box manually in the drawing then I would not consider that to be useful.
