Just happened to notice this today. Create a new drawing, place in a front view in of an assembly, place a side view, a top view and a top ISO view. Before I placed the first view, I clicked on the Model tab, selected Hidden Line Calculation to All Bodies, set Display Style as Edges as Part, and set a Margin value. After placing the views, I noticed the reference parts were displayed as parts in all the views EXCEPT the ISO view. The ISO view still showed them all as hidden lines. When I edited the ISO view, the Hidden Line Calculation was set back to Reference Data Separately, the Display Style set to Edges as Reference BUT the Margin value was still set to what I had set it to. Why the heck would you want the reference part display different in an ISO view than the view you projected it from???? This needs to stay the same settings regardless if projected flat plan or projected ISO.
