Lesson: Using Object Snaps ■ 99
About Object Snap
Every object you create has various selectable points that you can use to position other objects. Every
time you create an object you are required to specify a point or location. It is critical that these points
be defined accurately if you expect your drawing to be accurate.
Object Snaps Defined
The following image shows three of the most basic types of objects that you can create: a line, a circle,
and an arc. In this example, the line has two unique snap types with three possible locations that you
can select; the circle has two unique snap types with five possible locations that you can select; the arc
has three unique snap types with four possible locations that you can select.
1. Endpoint
2. Midpoint
3. Center point
4. Quadrant
Object snaps exist for each of the previously mentioned points and more. You use them to select those
points accurately. Attempting to accurately select these points without using object snaps would be
very time-consuming and inaccurate.
Effect of Using Object Snaps
In the following image, the smaller circle needs to be concentric within the larger circle. By using the
Center object snap, you can place the smaller circle precisely in the center of the larger circle.
By examining each circle's coordinates, you can verify that they both share the same center point.
