I've done this in models, but in the part drawing when I add a drawing view, the view states dialog box is grayed out for simplified representation.
Solved! Go to Solution.
Just to elaborate on what @MaheshSh said, part drawings treat simplified reps. as separate models. You can't take an existing view on a part drawing and switch it to a different rep. (like you can with assemblies.) Instead you have to first add the part to the drawing again, choosing the rep. when you add it, and then create a new view with that part (rep.) set as the active model.
