Using a two-point perspective can create accurate drawings with depth. First, draw a straight horizon line, and place dots called vanishing points at either end of the line. Then, as you draw your building, use a ruler to ensure that any parallel receding lines of the building follow back to one of the vanishing points.[8]
If it helps you create an accurate building, you can trace receding lines back to a vanishing point and then erase them later.
Vanishing points don't have to be placed on your page. It's helpful to do so if you're just starting out, but vanishing points are often located at imaginary spots further back from the page.
