Draw Hidden Faces Displays the object’s hidden backfaces. The backfaces are visible if the object is transparent, or if
the object is expanded and then pulled apart.
Note: If your object has transparency and you want the hidden backfaces to display through the transparent front faces,
apply the Object > Group command to the object before you apply the 3D
effect.
Preserve Spot Color (Extrude & Bevel effect and Revolve effect) Lets you preserve spot colors in the object. Spot
colors can’t be preserved if you chose Custom for the Shading Color option.

Lighting options
Light Defines where the light is. Drag the light to where you want it on the sphere.
Move Light Back button Moves the selected light behind the object.
Move Light Front button Moves the selected light in front of the object.
New button Adds a light. By default, new lights appear in the front center of the sphere.
Delete Light button Deletes the selected light.
Note: By default, 3D Effects assigns one light to an object. You can add and delete lights, but the object must always have
at least one light.
Light Intensity Changes the selected light’s intensity between 0% and 100%.
Shading Color Controls the object’s shading color, depending on the command you choose:
• None Adds no color to the shading.
• Custom Lets you choose a custom color. If you choose this option, click the Shade Color box to select a color in
the Color Picker. Spot colors are changed to process colors.
• Black Overprint Avoids process colors if you’re using a spot color workflow. The object is shaded by overprinting
shades of black on top of the object’s fill color. To view the shading, choose View > Overprint Preview.
• Preserve Spot Color Lets you preserve spot colors in the object. Spot colors can’t be preserved if you chose Custom
for the Shading Color option.
