Add lines, arrows, rectangles and ovals to PDF

The pre-defined drawing shapes, which include the Line  tool, Rectangle tool and Oval tool, are the simplest drawing markup tools to add quickly to your PDF documents. You can change the look (color, opacity, etc.) of all your drawings, and you can edit the straight lines so they use arrows and other pointer styles. All drawings you add have their own pop-up note attached, meaning you can add a text message to explain each drawing in more detail. (See PDF annotator feature overview for related information.)

To add a line, rectangle or oval drawing markup:

1. On the Commenting toolbar, click the arrow next to the Pencil tool.
2. Select the Line  tool, Rectangle tool or Oval tool.
3. Click and drag on the page to add the drawing.
4. Release the left mouse button to complete the shape.

To add a comment to your drawing markup:

1. Select the Hand tool from the toolbar.
2. Double-click the edge of the drawing.
3. In the pop-up note, enter your text message.

To update the appearance or properties of a drawing:

1. Right-click the drawing and select Properties.
2. Modify the color, opacity, etc.
3. Close the Comment Properties window.

Tip: You can change the default properties of your comments by right clicking on a note and choosing the Set Properties as Default option.

To open the Comments panel and view all comments, do one of the following:

• Select the Show/Hide Document panel  toolbar button, followed by the Comments panel  button.
• Choose View > Document panel > Comments.
• Use the F6 shortcut key, followed by the Comments panel  button.
