Note: The construction toolset is a part of the PRO subscription.
How to use the polygon and polyline tools:
- Open a file you’d like to work with.
- Select the Draw tab at the top.
- Select the Polygon or Polyline tool. You can select the color for each tool on the color picker. You also get access to other properties such as the border thickness, style, hatch patterns, fill color, and opacity.
- Follow the onscreen instructions.
- You can move your shape around, resize it, edit, or delete the polygon or polylines.

If you frequently use a particular shape, e.g. the red arrow, you can add it to the Favorites to work even faster. Learn how to create your own toolset in PDF Expert.
