About snapping

Snap behavior in Microsoft Office Visio positions and aligns shapes exactly. Snapping pulls shapes to one another or to ruler subdivisions, grid (grid: Nonprinting horizontal and vertical lines that appear at regular intervals on the page.) lines, guides (guide, guide point: A reference line you can drag onto the drawing page to position shapes precisely. Drag guides from the rulers, and the guide point from the upper-left corner of the drawing window.), or guide points (guide, guide point: A reference line you can drag onto the drawing page to position shapes precisely. Drag guides from the rulers, and the guide point from the upper-left corner of the drawing window.) so you can control placement and alignment. You can control what types of objects shapes snap to and the snap strength, which is the amount of pull that an object exerts.

Shape snapped to a ruler subdivision

By default, shapes snap to both ruler subdivisions and grid lines. To snap shapes more easily to ruler subdivisions, turn off snapping to grid lines.

 Note   You may not always want to snap shapes. For example, by turning off snapping, you may find it easier to draw a smooth, freeform curve (freeform curve: A shape with curved segments. Also called a spline.).
