Snaps give you control when creating, moving,
rotating, and sca ling objects, because they let you
snap to specific portions of existing geometry
during creation and transformation of objects or
sub-objects. The controls in this dialog set the
snap strength and other characteristics such as the
snap target.
Note: Snap functionality includes several features
thatenhanceeaseofuse.See
the Snap Options
topic
for details.
You can spec ify the portion of the geometry where
you will snap. For example, when Vertex is active,
creation and transforms snap to the vertices of
existing geometry. You can select any combination
to provide multiple snap points. If Ver tex and
Midpoint are active, snaps occur both at vertices
and at midpoints.
Grid Points is the default snap type .
Note: Snaps are not on by default. Turn snaps on
and off with the S keyinthemiddleofatransform.
You can use snaps with free positioning this way.
