This video demonstrates how to create a 3D Lego brick using the Illustrator. In this, first a circle is made and then, by using the "transform‚" mode, another circle is made. Then by the 3D command it is converted into a 3D image. Further you can copy these circles and make them 3D just like there are in Lego bricks. You can also use the 3D mode to do the same thing to the rectangle frame on which the circles were made. So this is how a 3 D Lego brick is made. This video is useful to people who love to work with Lego bricks.
