Are you looking for a quick an easy way to rearrange your home without moving a single piece of furniture? If so, you may want to check out Floorplan, a free Adobe Air application that allows you to draw out your floor plan and arrange furniture with a click of a button.
If you find that Floorplan’s interface, set of tools, and options are a bit basic, you are correct, it is a very simple application, but simplicity comes with its perks. To use the application all you have to do is select a shape, set the real world dimensions and place it on the graph paper, repeat until you have all your furniture laid out. There are two options that are really needed to make this application great; the ability to name the objects and the ability to set a boundary for the space you are working on. Other than that the application does a great job of allowing you to quickly draw objects on the screen.
Floorplan requires Adobe Air and can be downloaded free for Windows, Mac, and Linux from the Adobe Marketplace.
