Use Shaded Viewports
 
 
 

If your drawing contains 3D faces, meshes, extruded objects, surfaces, or solids, you can plot from Paper space using one of the values defined by the ShadePlotStype enum. Shaded and rendered viewports are previewed, plotted, and plotted to file with full shading and rendering.

The ShadePlot property of the Viewport object is used to set the option for plotting a shaded viewport.

NoteThe hidden lines for the objects in a Viewport object can be enabled with the HiddenLinesRemoved property. This property takes a boolean value: TRUE to remove hidden lines or FALSE to draw them.
