Hello, I am working on a series of sheets inside of one drawing file. The problem is that the display style will change. To be more specific, I click on an isometric view, go to "Display Style" and the five display style buttons show that "Shaded With Edges" is selected. However, the view is not shaded and shows random solid internal lines of the view. I've tried selecting another display style and selecting "Shaded With Edges" again but it doesn't work. The only times I get a shaded picture is when I either open the part and edit it, or when I delete the view and just create another one. Even then, if I try to print or save as a PDF, it changes to no longer being shaded and I'm back to where I started. It's also strange because it affects only a few of the sheets and not others.

I hope I have given sufficient info that will spark one of your expert SW minds with a solution or at least the source of this problem. Any ideas??
