Grid Points—Snaps to grid intersections.
This snap typ e is on by default. Keyb oard
shortcut=ALT+F5.
Grid Lines—Snaps to any point on a grid line.
Pivot—Snaps to pivot points of objects.
Keyboard shortcut=ALT+F6.
Bounding Box—Snaps to one of the eight corners
of an object’s bounding box.
Perpendicular—Snaps to the perpendicular point
on a spline, relative to the previous point.
Tangent—Snaps to a tangent point on a spline,
relative to the previous point.
Vertex—Snaps to vertices of mesh objects
or objects that can be converted to editable
meshes. Snaps to segments on splines. Keybo ard
shortcut=ALT+F7.
Endpoint—Snapstotheendpointsofedgeson
meshes or spline vertices.
Edge/Segment—Snaps anywhere along
edges(visibleorinvisible)orsplinesegments.
Keyboard shortcut=ALT+F9.

on meshes and spline segments. Keybo ard
shortcut=ALT+F8.
Face—Snaps anywhere on the surface of a

NURBS Snaps
These options snap to objects or sub-objects in a
NURBS model (page 3–1074) .
The NURBS snaps settings are aids for creating
and transforming objects, and are not constraints.
Thesoftwaredoesnotmaintaintherelationship
between the NURBS object and other objects you
create or transform.
CV—Snaps to a CV sub-object (page 3–1020) in a
NURBS curve (page 3–1074) or NURBS surface
(page 3–1075)
.
Point —Snaps to a point sub-object (page 3–1089)
inaNURBSmodel.
Curve Center—Snaps to the center of a NURBS
curve.
The center of a NURBS curve is calculated
parametrically, and might not be the same as the
curve’s apparent visual center.
Curve Normal—Snapstoapointnormaltoa
NURBS cur ve.
This snap operates only while you are creating
a new object that requires two or m ore clicks to
create.
Curve Tangen t—Snaps to a point tangent to a
NURBS cur ve.
This snap operates only while you are creating
a new object that requires two or m ore clicks to
create.
