It would be fantastic if there was a setting or way to ignore specific line styles, colors or on specific levelswhen caching dynamic views in the Hidden Line settings dialog. Currently we have to jump through a lot of extra hoops to show center lines on our drawings which are already modeled during our modeling process. I can trick the dynamic view into displaying them correctly with exceptions but when I translate to AutoCAD or cache the dynamic view they become hidden. Thus we have to re-draw all of these lines or over-lap multiple views(one with center lines and one without)both of which are not very elegant solutions.
