I'm trying to use the pen tool to trace perfectly over an existing curved path in Illustrator. I must be missing the obvious because I've been searching through tutorials and can't find anything about it.

Let's say I start out with the green vector object in the graphic. The next step is to draw another object with the pen tool (the dashed-line object). As you can see, part of the second object needs to overlap a portion of the first object exactly, so that there are no holes between the paths. In other words, the two objects must overlap perfectly in the area between the blue circles.
How do I use the pen tool to draw the dashed object so that the two objects overlap perfectly between the blue circles? I don't want to "eyeball it"...it needs to be an exact overlap.
