You can set the following
preferences in the Snapping category of the Preferences window.
With these options, you can control the size region around the mouse
pointer that is used for the snap operation.
Snapping
- Use snap tolerance
-
When
on, the snap region is restricted to a square area around the cursor,
defined by the Snap Tolerance option. When off, the snap region
is unlimited; you can snap to anything viewable.
- Snap tolerance
-
Controls the size of
the snapping area around the cursor when Use Snap Tolerance is
on. For example, if you have two curves close together and you try
snapping to one of the curves, the object may snap to the wrong
curve. To avoid this, try using a small Snap Tolerance value.
UV Texture Editor Snapping
- UV snap tolerance
-
This preference defines
how close UVs are together before they snap when moving and using
the v hotkey (snap to points).
Edge Snapping
- Snap magnets
-
Controls the number of
magnet points inside edges. For example, 3 means there are magnet points
at each end and in the middle.
- Magnet tolerance
-
Controls how “sticky”
each magnet is; that is, how close the point must be to a magnet
before the point snaps to it. Set this to 100 to constrain points
to always be at magnet points.
