Polyline Tool

1. Select the Polyline tool using one of the following methods:
   • Go to Markup > Lines > Polyline.
   • Click  on theMarkups toolbar.
   • Press SHIFT+N.
2. Click on the PDF to define the first point of the segmented line.
3. Click again to define the next point. A line segment is drawn between this point and the previous one. Repeat as needed.
4. To complete the line, double-click when placing the last point.
5. To close the line path and connect the last point to the first point, place the last point over the top of the first point.

Note: A Polyline is an open line, even if the first and last points touch. Use the Polygon tool to create a closed shape.

Tips:

• Hold down SHIFT to draw lines that are at horizontal, vertical, or 45° angles.

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.

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 a line or change its angle, click and drag the appropriate yellow handle.

To scale the markup up or down, click and drag the appropriate purple handle.

See Editing Markups for more information.

The appearance of the Polyline markup is configurable, including its color, thickness, pattern, ends, and opacity.

To change the appearance of a Polyline markup, select it and click the Properties tab.

Appearance Properties

Color: Sets the line color.

Fill Color: Controls the fill color of the endpoints.

Highlight: Makes the fill color and line transparent so underlying content shows through.

Opacity: Sets opacity level of the line and endpoints, from 0 (invisible) to 100 (opaque).

Line Width: Sets the line thickness in points.

Style: Determines the pattern of the line segment.

Line Start and Line End: Controls the appearance of the endpoints for each side of the line. The diagram below shows samples of each type of endpoint.

Each endpoint has an associated Scale that determines the size of the endpoint in relation to the Line Width. By default, it is set to Auto and will automatically adjust as the Line Width is changed.
