The Snap Function
The snap function provides assistance when inserting objects with the mouse. The function detects objects within a certain radius of the cursor and automatically positions the cursor at or on the object. In this dialog you can specify for all views whether the snap function should be active, to which objects it should apply and within which radius of the cursor. The radius should not be too large, otherwise it is likely that a number of objects will be found within the radius and the snap function is then no longer practical, or the cursor jumps back and forth between objects.
