Snap Override
Snap Overr ide bypasses currently selected snaps.
You use a keyboard-mouse combination or a
keyboard shortcut to define a new snap for the
next click. You can override on the fly, one snap
at a time.

grid points, you might need to snap to a vertex
or midpoint of an object. This is the general
procedure:
1. As you use preset snaps to create or move an
object, hold down

pops up a three-quadrant right-click menu,
which you can use to override the current snap
setting(s).
Note: You can begin the creation or
transformation process b efore accessing the
override menu. This t y pically means that
you’ll be holding down the left button as you
Shi f t +right-click.
2. From the Snap Override quadrant, choose the
snap type you want to use. The cursor switches
to this type.
3. Make the snap. After the snap, cur rently set
snaps are back in effect.
In addition, t he Snap Over ride quadrant lets you
reuse the last overr ide you used (listed by name),

snapping entirely on the next click. The Snap quad
menu also contains an Options quadrant, with

constraints (default=off) and snapping to frozen
objects (default=off).
