With shaded viewport options, you can choose how shaded objects are plotted, and you can specify the display resolution.
You can specify how shaded objects displayed on the Model tab and in layout viewports should be plotted. Shaded viewport plotting is limited in DWG TrueView and does not include visual styles or rendered views.
You can choose from several resolutions, up to the resolution of your plotter.
Shaded viewport plotting options apply to all objects in layout viewports and in model space.
