Drawing in linear perspective is accomplished by drawing guidelines that mark the horizon and the angle at which objects converge on it. A pencil with a soft lead is required to draw these lines because they need to be erased after the picture is completed.
- Draw a horizon line
Measure 1/3 of the way up the piece of paper and draw a horizontal line, called the horizon line, across the page. The line needs to be straight, so use a ruler. Measure to the midpoint of the line, and make a mark that serves as a vanishing point.
- Draw convergence lines
Use the ruler to draw several diagonal lines radiating out from the vanishing point to the edge of the paper. The distance between these lines should be wider as they go further from the vanishing point.
- Fill in the image
Use the horizon and convergence lines as a guide to fill in the objects in the drawing. Fit the objects between the lines so that they appear smaller as they come closer to the vanishing point. As an object reaches the convergence line, it vanishes.
- Erase the guidelines
When the picture is finished, erase the guidelines. Remember to erase gently so that the paper does not get torn.
