Object Snaps and Snap Shortcut Key Combinations
 
 
 

The following table defines the object snaps listed in the Snaps dialog (Manage tabSettings panel Snaps) and the shortcut key combinations for these objects. Shortcut key combinations override snap settings for one pick.

Object Snap Shortcut Key Description
Endpoints SE Snaps to the endpoint of an element or component.
Midpoints SM Snaps to the midpoint of an element or component. When placing a wall insert, such as a window, door, or opening, you can use the midpoint override, SM, to snap the insert to the midpoint of the wall segment.
Nearest SN Snaps to the nearest element or component. If you turn off the Nearest object snap by clearing the check box or using the keyboard override, Revit Architecture allows jump snaps to endpoints, midpoints, and centers. A jump snap is a snap point that is more than 2 mm away from the cursor on the screen.
Work Plane Grid SW Snaps to a work plane grid.
Quadrants SQ Snaps to quadrant points. For arcs, jump snaps are enabled.
Intersections SI Snaps to intersections.
Centers SC Snaps to the center of an arc.
Perpendicular SP Snaps to perpendicular elements or components.
Tangents ST Snaps tangent to an arc.
Points SX Snaps to site points when editing points using the Move or Copy tool.
Snap to Remote Objects SR This is similar to jump snaps. When you select this option, snaps look for objects that are not near the element.
Close SZ Snaps to close valid open loops. See Closing an Open Loop.
Turn Override Off SS Turns off snap overrides.
Cycle through snaps Tab key Cycles through the available snap options.
Reverse direction when cycling through snaps Shift+Tab Cycles through the available snap options in reverse order.
