Hello,
I think it would help to clarify the original request post and Title. We have a vector option, so what specifically is the new behavior you would like? The request is to have a second option to force Vector output even when it will not look like the view in Revit, correct? If you sent a print job or sheets with mixed settings the views that have settings or objects that require Raster would print/export vector and discard those things. So shaded, texture, and realistic views would change to hidden line, or Consistent Color, shadows would be removed, point clouds removed, Gradient backgrounds removed, coordination models removed, etc.
Would you want some report or warning for the changed views and viewports?
And what did you mean by fills? We are not aware of a fill setting or object that forces Raster. It would be good to clarify or remove that.
PDF Export and print should always be using the Vector option for each view and viewport it can with that option set. If you have cases that seem to be forced to Raster that should not be, then you could report those as problems.
