The third mode snaps the ''right'' side of the shell to the grid. The fourth mode will snap the shell ''relative'' to its current position. And the final mode snaps the shell ''bounding box'' to the grid. That is, it will snap which ever of the left or right edges is closest to the grid. |

Open up the Snap / Stack / Sort panel to snap shells to the grid, to stack similarly shaped shells over the top of or alongside each other, or to sort shells by various criteria. The stacking tool can also be used to make a single shell symmetrical.

To temporarily turn off all current snap settings, stow/hide the Snap/Stack/Sort panel.
StackThe stacking tools can be used in two ways:
SortSelect shells to sort them by the following criteria. If no shells are selected, then all visible unlocked shells are sorted.
