Sweet Home 3D is a free interior design software application that allows for the planning and development of floor plans, as well as the ability to arrange furniture on it and view the results in 3D.

Features

1. Draw walls only.
2. Change the color or the texture of the walls, the floors and the ceilings, importing images of your own patterns if needed.
3. Drag and drop doors, windows and furniture onto the plan from a catalog of objects organized by categories, in which you can import 3D models created by yourself or downloaded from the web.
4. Customize the size, the orientation, the elevation, the colors and the textures of each piece of furniture.
5. View the changes in the plan simultaneously in a 3D view, in which you can navigate either from an aerial view point, or from a virtual visitor view point.
6. Annotate the plan with room areas, dimension lines, texts and show the North direction with a compass rose.
7. Create a photorealistic image of your arrangement depending on the time of the day and the light sources placed in the plan.
8. Create a video from a virtual path in the 3D view.
9. Print the home plan and the 3D view or export them in files at PDF, PNG, JPEG, SVG, OBJ standard formats, to reuse designed homes in other software.
10. Extend the features of Sweet Home 3D with plug-ins programmed in Java, or by developing a derived version based on its Model View Controller architecture.
