Exa mple: To use S nap Previ ew:
The Snap Preview Radius setting lets you preview
a snap before it actually happens. The Snap Radius
setting determines when actual snapping occurs,
providing the same functionality as Snap Strength
in previous versions.
This procedure also demonstrates how to cycle
through available snap/prev iew points with the
keyboard shortcut.
1. Reset the software, and then maximize the
Perspective viewport.
To maximize the Perspective viewport, make
sure it’s active (yellow border), and then press
Alt+W .
2. Zoom in a bit so the grid s quares are relatively
large.
Snap and Snap Preview measure in pixels, so if
the grid points are relatively far apart, it’s easy
to see the difference between Snap Preview and
Snap.
