Using entity snaps
Entity snaps enable you to quickly select exact geometric points on existing entities without having to know the exact coordinates of those points. With entity snaps, you can select the end point of a line or arc, the center point of a circle, the intersection of any two entities, or any other geometrically significant position. You can also use entity snaps to draw entities that are tangent or perpendicular to an existing entity.
You can use entity snaps any time the program prompts you to specify a pointfor example, if you are drawing a line or other entity. You can work with entity snaps in one of two ways
- Enable a running entity snap that remains in effect until you turn it off by choosing an entity snap when no other command is active.
- Enable a one-time entity snap for a single selection by choosing an entity snap when another command is active. You can also use a one-time entity snap to override a running entity snap.
TIP If you type the name of the entity snap, you need to
type only the first three letters.
When using entity snaps, the program recognizes only visible entities or visible
portions of entities. You cannot snap to entities on layers that have been turned
off or to the blank portions of dashed lines.
When you specify one or more entity snaps, an entity snap target box is added to the crosshairs. In addition, an icon appears adjacent to the crosshair indicating the active entity snap. When you select an entity, the program snaps to the snap point closest to the center of the target box.
TIP Type m2p or mtp to enable a one-time
snap to the midpoint of two points that you specify, such as two points selected
using entity snaps.
