as though all the buildings and even the
road narrow down to one point. This is how
perspective drawings look.
When you look down the road, the
road and the buildings seem to come
from a single point. This point is called the
vanishing point. See Figure 13-28. The
line where the sky meets the road is the
horizon line. Vanishing points are always
located on the horizon line. The ground
line is the line formed at the front of the
sketch along the bottom of the objects.
There are several types of perspec-
tive sketches. See Figure 13-29. The
most common are one-, two-, and three-
point perspective sketches. The two-
point perspective sketch is one that has
many applications and is used regularly.
See Figure 13-30. To create a two-point
perspective sketch, the designer follows
these steps:
1. Draw the horizon line and the
ground line.
2. Add the vanishing points.
3. Sketch a vertical line from the ground
line that is the height of the object.
4. Sketch perspective lines from the
vanishing points to the top and
bottom of the vertical line. These
perspective lines form the left and
right sides of the sketch.
5. Sketch vertical lines that are the
width of the object.
6. Block out the shape.
