Everything I've seen, read, and done indicates you are SOL (Sorta Out of Luck). Unless you hit the 'Undo' button to get back to having the hatch lines (which means hiding them was one of the last few steps you'd done in the current session) then the only alternative is to delete the view and re-create it. I've complained about the same thing myself. No sign if its enough of a concern for AutoDesk to do anything about it.
In the detail view, RMB and select show hidden lines (working from
memory so exact wording may differ), then pick the hatching or select
show all and then turn off visibility of things you don't want.

I had the same problem. First right-click on your view and select "edit view"; go to "display options" tab, un-select "hatching", hit "ok". All your hatching will dissappear at this point. Next right-click your view again, select "edit view", go to "display options" and re-select "hatching". Click "ok" and all default hatching for the entire view will come back. (BTW working with Inventor 2014 Pro).
