Snap to Objects and Snap Align are two options useful to align, join and draw more precisely shapes in the Stage.

Snap to Objects

The "Snap to objects" option can be selected from View -> Snapping -> Snap to Objects, or from the "Snap to Objects" button on the options area of the "Tools panel" (the icon with the image of a magnet, see the picture below).
Select Snap to Objects
- If Snap to Objects is enabled, it displays a small, thick circle under the pointer, when you draw a perfect circle, a square, a perfect vertical and horizontal line, or when the object is within snapping distance of another object.

- When this option is enabled, it forces to merge the line or the shape when it comes close to other object. When you want to draw lines or shapes close to each other, it is indicated to disable "Snap to Objects".
- The Snap tolerance can be adjusted from Edit -> Preferences, then choose Drawing. In that window, to the Connect lines you can select: "Must be close", "Normal", or "Can be distant".
- Snap to Objects not work with the Pencil, Brush, or Eraser Tools.

Snap Align

To enable "Snap Align", click View -> Snapping -> Snap Align.
