I have a drawing that is referencing a model that is nowhere in the drawing. The only way I know it's referencing it is when I do a pack and go the errant model is listed. If I just pack and go the assembly model that the drawing is actually for the errant model isn't list. Therefore I know the drawing is referencing the errant model somehow. What can I do to figure out how the drawing is referencing that model? I've checked for hidden views, but there are none.
