Endpoints and Closed Paths
Where to begin? Let’s start simply and build our way up. First, we’ll
look at lines, which Illustrator calls open paths because they have
endpoints—points at the end of the lines, points that stop. (The
upper half of Figure 2-2 shows one of an open path’s endpoints.)
They’re out there, on the market. They’re single points. Maybe
they fi nd another point, maybe they don’t. They’re not quite ready
to settle down.
Then we’ll move on to shapes. Illustrator calls these closed paths
because they don’t have endpoints. These shapes aren’t closed in
the sense of “shut down,” it’s just that they aren’t accepting new
points. The points are married, really. Except that they’re binoga-
mous—every point is joined to two other points, so the shape con-
tinues forever and ever, as shown in the lower half of Figure 2-2.
Drawing Lines, Arcs, and Spirals
In these fi rst two exercises, we’re going to be working with a fi le
you fi rst saw in the preceding lesson—the eye of Horus. This time,
however, you’ll get to actually illustrate in Illustrator, not simply set
up guides. The fi rst exercise will focus on draw-
ing paths using the various tools available from
the line segment tool ( ) fl yout menu. Time to
start drawing!
