FormSketch comes with a library of many professionally designed icon sets for various different industries, so that no matter your business needs there should be something that can be used.
In FormSketch, select the Icons option in the drawing menu at the bottom of the screen. You can then search or select the industry type in a dropdown, or select the magnifying glass tool and use the search bar to find a suitable icon.
(Note: If there are specific icons for your industry that cannot be found in the library, then you can contact Support at support@formitize.com and ask about having a set of icons added.)
To add the icon to the map, simply select what icon you'd like to use and then tap / click on the spot in the map that you would like it to be.
After you have placed a symbol on the map, it will be added to the used icons list in the bottom right corner of the map grid itself.
