In one sentence, describe what the following article is about:

Decide whether you want to view your block letters from above or below, and whether you want them to face to the right or the left. If you were looking at them straight on from the front, they'd just look like ordinary block letters, so you have to tilt them to make it 3D. Your vantage point will determine the direction your draw your diagonal lines in the next step. Be sure to draw all of the lines so that they tilt in the same direction. If it helps, choose a vanishing point in the background. Then, use a straight edge to line up each line with that vanishing point before you draw it. If you're viewing your letters from above, the lines should tilt up. If you're viewing from below, they should tilt down. Draw the lines to the right if you want your letter facing left and to the right if you want them facing right. Practice drawing these lines in different directions until you figure out what you like. Most people draw their block letters viewed from above. Use horizontal, vertical, and curved lines to connect the ends of the diagonal lines. This will be drawing the back side of the letters. Think of it like drawing a cube, where you first draw a square, then small diagonal lines, and then connect the lines in another square. It's just like that, except the shapes are letters instead of squares.

Summary:
Choose a vantage point for your letters to make them 3D. Draw small diagonal lines from the corners of your letters in pencil. Connect the ends of the diagonal lines together.
