The following table defines the object snaps listed in the Snaps dialog (Manage tab
Settings panel
Snaps) and the default 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 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. |
| Force Horizontal and Vertical | Shift key | Forces horizontal and vertical constraints. |
| Snaps Off | SO | Disables all snap settings. |
