Sketch Snaps

Each Sketch Snap allows you to automatically snap to selected entities as you sketch. By default, all Sketch Snaps except Grid are enabled. You can control all Sketch Snaps through snap options.

Access Sketch Snaps through the Quick Snaps toolbar, the Quick Snaps flyout on the Sketch toolbar, or the shortcut menu.

Use Sketch Snaps with sketch entities, model edges in parts, assemblies, and drawings.

On sketches with multiple entities, only the current sketch entity displays snaps.

Sketch Snaps	Tool	Description
End points and sketch points		Snaps to the end of the following sketch entities: lines, polygons, rectangles, parallelograms, fillets, arcs, parabolas, partial ellipses, splines, points, chamfers, and centerlines. Snaps to the center of arcs.
Center Points		Snaps to the center of the following sketch entities: circles, arcs, fillets, parabolas, and partial ellipses.
Midpoints		Snaps to the midpoints of lines, polygons, rectangles, parallelograms, fillets, arcs, parabolas, partial ellipses, splines, points, chamfers, and centerlines.
Quadrant Points		Snaps to the quadrants of circles, arcs, fillets, parabolas, ellipses, and partial ellipses.
Intersections		Snaps to the intersections of entities that meet or entities that intersect.
Nearest		Supports all entities. Clear Nearest Snap, to enable all snaps. Your pointer does not need to be in the immediate vicinity of another sketch entity to show inference or snap to that point. Select Nearest Snap, and snaps are enabled only when the pointer is in the vicinity of the snap point.
Tangent		Snaps to tangents on circles, arcs, fillets, parabolas, ellipses, partial ellipses, and splines.
Perpendicular		Snaps a line to another line.
Parallel		Creates a parallel entity to lines.
Horizontal/vertical lines		Snaps a line vertically to an existing horizontal sketch line, and horizontally to an existing vertical sketch line.
Horizontal/vertical to points		Snaps a line vertically or horizontally to an existing sketch point.
Length		Snaps lines to the increments that are set by the grid, without requiring display of the grid. To enable Length Snaps, press and hold Shift while sketching.
Grid		Snaps sketch entities to the grid’s vertical and horizontal divisions. This is the only sketch snap that is not active by default. If Grid Snap is cleared, it never snaps to grid. If Grid Snap is selected: Only snaps to grid if Snap only when grid is displayed is selected. Always snaps to grid (even if the grid is not displayed) if Snap only when grid is displayed is cleared.
Angle		Snaps to angles. To set the degrees, click Tools > Options > System Options > Sketch, select Relations/Snaps, and set a value for Snap angle.
