Using a feature set based on known principles of perspective drawing, you may quickly create or render artwork in perspective in Illustrator.
The perspective grid enables you to simulate a scene on a flat surface as it is normally viewed (by the human eye). For example, a road or a pair of railway lines that seem to meet or disappear in the line of sight.
Step 1:
Select the object of your choice.
Step 2:
To use the Perspective Grid tool, go to the Tools panel and click Shift+P.
Step 3:
Drag and drop the ground level widget to the left or right side of the grid. The pointer changes as you move it over the ground level spot.
This is how you can create perspective to any shape in Adobe Illustrator. In the video I perform this tutorial on a square, check out the video to learn in detail.
