I've got a drawing with several viewports that need to plot as hidden (hideplot on). I select the viewports and change their 'Shade plot' property to hidden. They will then print with a hidden view, as expected...but the second the drawing is refreshed/regenerated, all the viewports go back to 'As Displayed'. I've tried locking the display, but that had no affect.
I'm using Mechanical 2012.
