Entering the Endpoint of an Entity
Endpoint snap allows you to enter a point at the nearest endpoint on an
existing line, arc, polyline segment, or polygon segment. As you move the
pointer over the drawing, a square AutoPoint Indicator identifies the nearest
endpoint of any entity you pass over. Endpoint snap is handy for connecting
one entity to the endpoint of another entity. Lines and arcs have two end-
points. Polylines and polygons have an endpoint for each segment.
To enter the endpoint of a line, arc, polyline segment, or polygon segment
1 While in a drawing mode, activate Endpoint snap on the Snaps toolbar.

TIP Endpoint snap is the same as Jump snap set to 0%.
Entering a Point Where Two Entities
Intersect
There are two types of Intersection snaps which allow you to enter a point at
the intersection of two entities. These entities can include lines, arcs, circles,
polygon segments, or polyline segments.
■
Intersection snap allows you to enter a point at the apparent intersection of
two entities—meaning the point entered falls on both entities.
Intersection snap is available in MultiSnap mode.
■
2-Point Intersection snap allows you to enter the projected intersection of
two entities. The intersection point of the two entities does not have to
fall on either entity. If the infinite extension of either entity results in a
valid intersection point, AutoSketch enters that point. If the entities inter-
sect in more than one location, as in the case of intersecting arcs,
