Tolerance
A threshold distance used by simplify, snapping, and some repair operations.
Category: Operations
Definition (expanded)
Tolerance controls how aggressively a tool changes geometry. Higher tolerance usually means fewer vertices or more snapping. Pick tolerance based on your data scale and the smallest feature you must preserve.
