Creating shaded images
Creating a shaded image of your drawing removes hidden lines and then applies shading to the visible surfaces based on their entity color. Because they are intended to provide a quick visualization, shaded images do not have a light source and use continuous colors across surfaces, causing them to appear flat and unrealistic.
To create a shaded image
Type shade and then press Enter.
To control the appearance of the shaded image, choose Tools > Drawing Settings, and then click the 3D Settings tab and select the options you want. You can shade the surfaces and edges of the model in four ways:
Faces shaded; edges not highlighted.
Faces shaded; edges highlighted in the background color.
Faces filled in the background color; edges drawn using the entity color (similar to a hidden-line view).
Faces filled using the entity color; edges highlighted in the background color.
Use a visual style.
Choosing a shaded visual style (View > Visual Styles) is similar to using the Shade command. For more details, see Displaying a drawing with a visual style.
