Operation Manual

• Perspective On/Off – switches perspective projection on or off for a 3D object.
Perspective projection is where projecting lines from the center of projection pass through
an imaginary plane until they meet at a point some distance from an object.
3D Effects – Geometry
On the Geometry page of the Effects dialog (Figure 172) you can make changes to the geometry
of a 3D object.
• Geometry – defines the properties for a 3D scene or shape created from a 2D object.
– Rounded edges – enter the amount by which you want to round the corners of a 3D
shape as shown by the example in Figure 173. The default setting for rounded edges is
10%
Figure 173: Rounded edges example
– Scaled depth – enter the amount by which to increase or decrease the frontal area of
the selected 3D object. Figure 174 shows an example where the scaled depth has been
increased to 150% and then decreased to 50%. The default setting for scaled depth is
100%.

– Rotation angle – enter the angle in degrees to rotate a 2D object that has been
converted to 3D using the To 3D Rotation Object tool. Figure 175 shows an example
of a 2D circle converted to 3D and the rotation angle changed to 150 degrees.
