Yes! With Formsketch, you have multiple options for furniture items or landscaping icons to use in order to enhance your mapping experience and make it easier to read / understand.
In the bottom menu of the Formsketch application, select the Icons option. This will bring up a menu with many different icons of objects that you might find in a house / property. Adding an icon is as easy as selecting the one that you would like to use, and then clicking on the area in the map where you would like it to go.
If you want to move the icon to another spot in the map, then just select the arrow tool in the top menu, and select the imagine. You will be able to move it around, increase or decrease the size of the object, and delete it by selecting the delete option in the top sidebar and clicking on the icon.
