3D in Illustrator CS, Part 3
Creating symmetrical 3D objects using Revolve

Pretty simple. And there are also additional controls for manipulating your final 3D effect. For example, if we take a look at our original sample object, we can turn off our Cap (to create a hollow effect) and also play around with the Offset value. Offset actually shifts the center, or hub, of your object. So, as you see in the example below, if I set the offset to something like 70, I'm actually pushing everything outward to create a wider object.

[an error occurred while processing this directive]In this case, the Revolve effect is offset from the left edge of my path, but I can also do it from the right edge to get an inverted appearance.

Finally, we also have the Angle value to modify the appearance of our object. This particular value actually determines the degree to which the Revolve effect completes itself. Let's look again at a circular 2D object Revolved to 180 degrees instead of 360 degrees.



And you see that we wind up with a half-doughnut effect.

Using Revolve to create a texture-mapped sphere
So now let's apply some of this information to a simple project with a texture map and some adjustments to lighting. For this example, I'm not going to get into anything complicated, just a representation of a hypothetical planet with a wedge cut out of it showing its hypothetical core. I'm going to begin by creating a circle using the Ellipse tool. I'm then going to slice off half of it to form a semi-circle. Important: Make sure your shape has only a fill and not a stroke. Otherwise, Illustrator will create additional surfaces that will be difficult to manage when mapping an image to the surface.
