You can attach a note to nearly any markup that does not have a text box of its own. Simply double-click the markup to open the Note pop-up window. Notes attached to markups are functionally similar to the Note Tool.

You can add an action to nearly any markup. Simply right-click the markup and select Edit Action to open the Action dialog box.

Select a markup to reveal its control handles. Each handle controls a different aspect of the markup's size and orientation.

To rotate the markup, click and drag the orange handle outside the markup (when the markup is first placed, it will be at the top). By default, the markup is rotated in increments of 15°; to rotate in increments of 1°, hold down SHIFT while dragging.

The rotation can also be entered in the Rotation field found in the Layout section of the Properties tab.

To resize the markup, click and drag the appropriate yellow handle. When dragging the control handles at the endpoints of the line, the arc will automatically continue on its original ellipse. To automatically lengthen or shorten the arc in 15° increments, hold down SHIFT while dragging.

See Editing Markups for more information.

Note: An Arc is an open line. While their endpoints can nearly touch, arcs cannot be closed into a ellipses. Use the Ellipse Tool to create an ellipse, if desired.
