Snaps to the visual intersection of two objects that do not intersect in 3D
space but may appear to intersect in the current view.
Extended Apparent Intersection snaps to the imaginary intersection of two
objects that would appear to intersect if the objects were extended along their
natural paths. Apparent and Extended Apparent Intersection do not work
with edges or corners of 3D solids created in AutoCAD.
NOTE You might get varying results if you have both the Intersection and Apparent
Intersection running object snaps turned on at the same time.
Parallel
Constrains a line segment, polyline segment, ray or xline to be parallel to
another linear object. After you specify the first point of a linear object, specify
the parallel object snap. Unlike other object snap modes, you move the cursor
and hover over another linear object until the angle is acquired. Then, move
the cursor back toward the object that you are creating. When the path of the
object is parallel to the previous linear object, an alignment path is displayed,
which you can use to create the parallel object.
NOTE Turn off ORTHO mode before using the parallel object snap. Object snap
tracking and polar snap are turned off automatically during a parallel object snap
operation. You must specify the first point of a linear object before using the parallel
object snap.
