Most people think you have to set up a rigid perspective grid before you even start drawing. In this lesson we are flipping that idea upside down. I will show you how to draw your object first and then reverse engineer the vanishing points so the grid obeys your rules.

We will sketch out an airplane to see this in action. You will learn how to place planes exactly where you want them, construct cylinders for the engines, and add speed lines to give the sketch some life. This approach is especially useful for storyboarding or any time you need a specific composition without being restricted by a pre-made grid.
