Click the Geometry
button at the top of the 3D Effects
dialog box if needed, to display the Geometry
settings. Here you can adjust the amount of roundness in the Rounded edges
of your object, and the ratio of the front face of the object to its back face (the Scaled depth
). The Rotation angle
applies only to a 3D rotation object
and controls whether the profile is rotated a complete 360 degrees to create the object. You can adjust the amount of extrusion by changing the Depth
125. Apply 3D Effects
and Vertical Segment
amounts apply to rounded shapes; by increasing these values, you can make a rounded shape more smooth. The higher these values, however, the longer your shape will take to draw. The Normals
affect how your object's surface is rendered when lit and when a texture is applied. These settings are best left at Object Specific
, which selects the best formula for each object. With Flat,
you can let each of the vertical and horizontal segments become more apparent, or smooth them with Spherical
. You can invert the Normals
, which makes an object appear as if lit from within. You can choose Double-Sided Illumination,
which simulates both interior and exterior lighting. You can also create Double-Sided
, or open ended, 3D objects, like an open ended box.
On each page of this dialog box, after setting the effects you want, click the Checkmark
button to apply them to the selected 3D object.
KEY TERM 3D rotation object
Created with the Modify, Convert, To 3D Rotation Object
command, this type of object starts as a profile which is then rotated 360 degrees through its y-axis (a pole running up and down through its center).
Understanding all the mathematics that produce appropriate 3D effects is fairly advanced. This task just skims the surface of the 3D effects you can apply. Fortunately, you can always try one of the options, adjust the 3D effect, and then select the Undo command to back up and try something else.
