Description

Snapping means "gluing" your next point onto an existing point or feature.

Snapping is available with most Draft and Arch Workbench tools, and can be enabled and disabled globally with the File:Snap Lock.svg Draft ToggleSnap command.

Each snap method can also be enabled or disabled individually by clicking the corresponding button on the snap toolbar, which can be made active with the menu View → Toolbars → Draft Snap.

Available snap locations

File:Draft ToggleGrid.png Toggle grid: only shows or hides the grid.
File:Snap Near.png Near: snaps to the closest point or edge on the nearest object.
File:Snap Extension.png 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.
File:Snap Parallel.png Parallel: snaps on an imaginary line parallel to a line segment. Hover the mouse over the desired object to activate its parallel snap.
File:Snap Grid.png Grid: snaps to the intersections of the grid lines, if the grid is visible.
File:Snap Endpoint.png Endpoint: snaps to the endpoints of line, arc and spline segments.
File:Snap Midpoint.png Midpoint: snaps to the middle point of line and arc segments.
File:Snap Perpendicular.png Perpendicular: on line and arc segments, snaps perpendicularly to the latest point.
File:Snap Angle.png Angle: snaps to the special cardinal points of circles and arcs, at 45° and 90°.
File:Snap Center.png Center: snaps to the center point of arcs and circles.
File:Snap Ortho.png Ortho: snaps on imaginary lines that cross the last point, and extend at 0°, 45° and 90°.
File:Snap Intersection.png Intersection: snaps to the intersection of two line or arc segments. Hover the mouse over the two desired objects to activate their intersection snaps.
File:Snap Special.png Special: snaps on special points defined by the object. introduced in version 0.17
File:Snap Dimensions.png Dimensions: lets you snap to one of the three lines making up the draft dimension.
File:Snap WorkingPlane.png Working plane: always places the snapped point on the current working plane, even if you snap to a point outside that working plane.

Options

File:Snap Lock.png Lock: turns snapping on/off globally
Certain additional snap locations can be obtained by combining 2 snap locations, such as ortho + extension, that will give you a snap point at the intersection of their imaginary lines.
Other, more complex snap locations can also be obtained by using constraining (by pressing SHIFT or X or Y or Z while drawing).
Pressing L while drawing locks the current angle of the line segment being drawn.
The maximum distance at which a point is snapped a snap location is specified in the preferences, and can also be changed on-the-fly by pressing [ or ] keys.
Pressing Q while drawing inserts a hold point at the current location of the mouse cursor. You will then be able to snap orthogonally to those hold points, and at the intersections of their orthogonal axes. If midpoint snapping is enabled, you will also be able to snap at the mid distance between any two hold points. introduced in version 0.17
