Impress Guide

• From the Extrusion on/off icon on the drawing toolbar. Select
the shape to which apply a 3D effect, then click the button on
the Drawing toolbar (see Figure 81).
Caution
You can not apply extrusion to rectangular and oval shapes
created by using the rectangle or oval tools. Instead, select the
desired shape from the basic shapes menu to create a rectangle
or oval with 3D effects. Alternatively, right-click on the object,
then select Convert > To 3D. Note that in this case the
Extrusion on/off menu will not be enabled.
Although Impress offers advanced functions to manipulate 3D objects,
this book describes only the 3D settings applicable to an object with
Extrusion enabled. For additional information on how to use advanced
3D effects such as geometry and shading, refer to the Draw Guide.
Click on to activate the extrusion. The shape changes and a default
thickness is added to it. At the same time the 3D-Settings toolbar
should become visible. If the toolbar does not appear, select View >
Toolbars > 3D-Settings.
