Sweet Home 3D is a free interior design application that helps you place your furniture on a house 2D plan, with a 3D preview. Whether you think Apple's decision is right or not, Mac OS X users should be aware that, until further notice, Sweet Home 3D won't be able to run under Mac OS X Lion, because it needs Java to run. If you weren't aware of this requirement, it's normal because even if this web site speaks about Java in various places, you don't have to know in which language Sweet Home 3D is programmed to run it.
You can design indoor settings very accurately thanks to the measurement system that's integrated into Sweet Home 3D. Creating a room is as simple as dragging a pair of lines onto a floor plan because the program generates the 3D model automatically.
Don't worry about the door or window spaces because sweet Home 3D creates that space when you place a window or a door on a certain wall.
Finally, the gallery of objects you can use is vast and you can even add new ones, as long as they're OBJ, LWS or 3DS format. Give it a try, remember, it's totally free and it can help you save a lot of money.
