Draft Snap

Description
The Draft Workbench tools allow you to pick points and distances by clicking on the 3D view with the pointer, or by entering coordinates in the task panel of the tool.

Another way of selecting points is by snapping. Snapping means "gluing" your next point onto an existing point or feature of another object.

Snapping is available with most Draft and Arch Workbench tools, and can be enabled and disabled globally with the button, located in the snap toolbar:.



Draft Snap toolbar

 * [[Image:Draft_ToggleSnap.svg|32px]] Toggle snap: toggles object snapping globally on or off.
 * [[Image:Snap_Endpoint.svg|32px]] Endpoint: snaps to the endpoints of line, arc and spline segments.
 * [[Image:Snap_Midpoint.svg|32px]] Midpoint: snaps to the middle point of line and arc segments.
 * [[Image:Snap_Center.svg|32px]] Center: snaps to the center point of arcs and circles.
 * [[Image:Snap_Angle.svg|32px]] Angle: snaps to the special cardinal points of circles and arcs, at multiples of 30° and 45°.
 * [[Image:Snap_Intersection.svg|32px]] Intersection: snaps to the intersection of two line or arc segments. Hover the mouse over the two desired objects to activate their intersection snaps.
 * [[Image:Snap_Perpendicular.svg|32px]] Perpendicular: on line and arc segments, snaps perpendicularly to the latest point.
 * [[Image:Snap_Extension.svg|32px]] Extension: snaps on an imaginary line that extends beyond the endpoints of line segments. Hover the mouse over the desired object to activate its extension snap.
 * [[Image:Snap_Parallel.svg|32px]] Parallel: snaps on an imaginary line parallel to a line segment. Hover the mouse over the desired object to activate its parallel snap.
 * [[Image:Snap_Special.svg|32px]] Special: snaps on special points defined by the object.
 * [[Image:Snap_Near.svg|32px]] Near: snaps to the closest point or edge on the nearest object.
 * [[Image:Snap_Ortho.svg|32px]] Ortho: snaps on imaginary lines that cross the last point, and extend at 0°, 45° and 90°.
 * [[Image:Snap_Grid.svg|32px]] Grid: snaps to the intersections of the grid lines, if the grid is visible.
 * [[Image:Snap_WorkingPlane.svg|32px]] Working plane: always places the snapped point on the current working plane, even if you snap to a point outside that working plane.
 * [[Image:Snap_Dimensions.svg|32px]] Dimensions: shows temporary X and Y dimensions while snapping.
 * [[Image:Draft_ToggleGrid.svg|32px]] Toggle grid: toggles the visibility of the grid on or off.

Advanced snapping

 * Press one or more times to snap to an object that is obscured by other geometry. This known as "snap cycling". Note that you must move the pointer by a small amount in the 3D view after pressing the key.
 * Additional snap points can be obtained by combining two snap options. For example combining Draft Snap Ortho and Draft Snap Extension will give you a snap point at the intersection of their imaginary lines.
 * Other snap points can be obtained by using Draft Constraints: by holding, or pressing , or.
 * Press to insert a "hold point" at the current location of the pointer. You can snap to the orthogonal axes of hold points, and to the intersections of these axes. If the Draft Snap Midpoint option is enabled, you can also snap to the midpoint between two hold points.

 * When Draft or Arch command requiring point input is active, the maximum distance at which Draft Snap Grid detects the intersections of grid lines can be changed by pressing (increase key) or  (decrease key). This setting is stored: . It can also be changed in the task panel of the Draft SelectPlane command.
