2D Snap—The cursor snaps only to the
active construction grid, including any geometry
on the plane of that grid. The Z axis, or vertical
dimension, is ignored.
2.5D Snap—The cursor snaps only to the
vertices or edges of the projection of an object
onto the active grid.
Suppose you create a g rid object (page 3–951) and
make it active. You then position the gr id object

off in 3D sp ace. Now with 2.5D set, you c an snap
a line from vertex to vertex on the distant cube,

3D Snap—This is the default. The cursor
snaps directly to any geometry in 3D space. 3D
snapping lets you create and move geometry in all
dimensions, ignoring the construction plane.

Angle Snap Toggle determines the incremental
rota tion for a number of features, including the
standard Rotate transform. As you rotate an object
(or group of objects), the object moves around a
given axis in the increment you set.
Angle Snap Toggle also affects Pan/Orbit camera
controls, FOV (page 3–937) and Roll camera
settings, and Hotspot/Falloff (page 3–954) spotlight
angles.
Procedures
To tur n a ngle sna p on:
• Click Angle Snap Toggle on the Main to olbar.
When turned on, angle snap affects all
rotational transforms.

To rotate an object a precise degree of r otation, do
one of the fol lowing:
• Click Select And Rotate, then right-click it
to displa y the Transform Type-I n dialog (page

the precise degree of rotation you need, then
rotate the object. Rotation snaps to the angle
increment you specified.
