Learn how to draw a cube in 3D with two point perspective in simple steps. First draw a simple cube on a piece of paper by outlining it using a pencil. Now darken the right front side and its top side by sketching the area with the pencil. Now sketch out an image coming out from right side of the cube like a shadow. Sketch the insides of the shadow part and darken the right side of the cube. When finished sketching draw a line to the left and right side of the cube in its middle.
